Much later in terms of quantity of high level radioactive waste than it was originally designed for.” This represents 125 million curies of radioactive cesium-137 and the NRC has reported that up to 100 percent of the hazardous material could be released from a pool fire, Kamps said. “I would like to point out that Fukushima Daiichi units one, two, three and four combined in terms of the inventory of high level radioactive waste in their storage pools does not match some of these reactors I mentioned in terms of how much waste is in these pools,” Kamps said. “So the risks are greater here for boil downs and the consequences of a radioactive fire in these pools.” Fortunately, the people who are not a part of the antinuclear community are finally beginning to recognize their own strength and to realize that they do not have to remain silent while the lies are being spread.

  • NOTHING happend to the fuel in the pools at Fukushima. I would like to see some evidence other than the word of an activist who frightens kids for a living to support Gunter’s rant about peices of fuel being ejected miles away. From the looks of that video, the fuel didn’t move an inch. There is also a poll associated with the article. The poll discloses that it is completely unscientific, since it allows anyone to vote and is not based on randomly selected participants. However, I think that the results as of 0315 this morning are pretty amusing since the antinuclear opinion piece has been posted for nearly a week.
  • Perhaps this October 12, 2011 post titled Oyster Creek Response that was published on Clean Energy Insight has something to do with the way the results are shaping up with 1029 out of 1080 respondents (95.3%) saying that Oyster Creek should not stop operating. Here is one more example of how inbred the group of antinuclear activists has become. I am talking here about the people who are so adamantly opposed to using nuclear energy that they do not even want existing nuclear plants to keep on producing clean, emission free, low cost electricity. Michael Mariotte of NIRS makes the following extraordinary claim: Ninety-five percent of the people in the world know about Fukushima, Michael Mariotte of the Nuclear Information and Resource Service said.
  • “It took a really extraordinary event for 95 percent of the people in the world to know about it,” he said. “If they know about Fukushima, they know about Mark 1 reactors exploding in the air and releasing toxic radiation across the world and they know that’s not a good thing. Something has to be done to make sure that never happens again.” I could not let that one pass without a comment; I am quite sure that Mariotte has once again fallen victim to the fact that he surrounds himself with people who echo his own prejudices. Here is my response.
  • Marriotte makes an interesting statement by he claiming that “95% of the people in the world” know about Fukushima. That statement might be true about the people in the United States, where advertiser-supported television news programs covered the events with breathless hype for several months. I am pretty sure that you would have a difficult time finding anyone in China, central Africa, the Asian subcontinent, South America or the Middle East who can even pronounce Fukushima, much less know anything about GE Mark 1 containments. Most of them would not even know that they should be worried about radiation because they have never been taught to be afraid of something that they cannot smell, feel, taste, or hear especially when it occurs at levels that have no chance of making them sick within their expected lifetime. Mariotte, Gunter, Kamps, Katz and Bridenbaugh are all members of a vocal, but tiny group of people who have been carrying the water of the fossil fuel industry for decades by opposing nuclear energy, the only real competitor it has. They are victims of groupthink who believe that their neighbors in Takoma Park are representative of the whole world.
  • Just before making this comment, I voted in the unscientific poll associated with the article. 95% say that Oyster Creek should keep on powering New Jersey homes and businesses. They are not impressed by the Beyond Nuclear FUD; they like clean electricity.

Oldbury 1 to shut down in early 2012 [23Oct11] - 0 views

  • After 44 years of operation, unit 1 of the UK's Oldbury nuclear power plant will be permanently shut down in February 2012, ten months earlier than expected, Magnox Ltd announced.
  • The company said that further operation of the 217 MWe Magnox reactor was "no longer economically viable." The decision to shut down the unit - the only operational reactor at the site - was taken "after careful consideration by operators Magnox and the site owners the Nuclear Decommissioning Authority (NDA), in conjunction with independent regulators the Office for Nuclear Regulation (ONR)."   Built in the 1960s and among the first generation of UK reactors, both of the gas-cooled, graphite-moderated first generation reactors at Oldbury were originally scheduled to shut down at the end of 2008. However, the NDA requested permission from the regulator to operate beyond that date, earning revenue to help pay for decommissioning. While unit 2 was eventually shut down in June 2011, unit 1 was expected to close at the end of 2012. To date, the site has generated over 130 terawatt-hours (TWh) of electricity.  
  • Oldbury site director Phil Sprague said, "Oldbury's excellent generation history is a terrific success story, especially as the site was originally planned to close in 2008. As a result of excellent teamwork between Magnox, the NDA and ONR the site's operational life was extended until February 2012, and it is a testament to the skills and dedication of the workforce who have operated and maintained the reactors to such a high standard that it has been able to continue to generate safely."   Magnox Ltd noted that since their originally planned shut down date of 2008, the two units have generated an additional 7 TWh, worth an estimated £300 million ($478 million) to the British taxpayer. This extra generation, it added, also saved some six million tonnes of carbon from being released into the atmosphere.   NDA executive director for delivery Mark Lesinski commented: "The income from electricity sales has provided an important contribution to the funding for our decommissioning program. Magnox and NDA will now work with stakeholders to ensure a smooth transition into the next stage for the site which will involve defueling and subsequent decommissioning."

  • Under current plans, the operation to remove the fuel from both units should be completed in 2013. After most of the structures at Oldbury have been removed, the site will enter the 'care and maintenance' stage of decommissioning around 2027, after which the reactor is left to cool. Final site clearance activities are scheduled between 2092 and 2101.   The last two remaining Magnox reactors currently in operation in the UK are at Wylfa site. The two 490 MWe units there are scheduled to shut down at the end of 2012.   Horizon Nuclear Power - a 50-50 joint venture between RWE nPower and EOn UK - plans to submit a planning application for a new nuclear power plant at Oldbury around 2014. According to the company, "Given the right market conditions, and subject to a final investment decision, preliminary works could begin in 2016, followed by main construction from 2019." Horizon is yet to decide which of the two available reactor designs - Areva's EPR or Westinghouse's AP1000 - it would like to build.

CPS must die [24Oct07} - 0 views

  • Collectively, Texas eats more energy than any other state, according to the U.S. Department of Energy. We’re fifth in the country when it comes to our per-capita energy intake — about 532 million British Thermal Units per year. A British Thermal Unit, or Btu, is like a little “bite” of energy. Imagine a wooden match burning and you’ve got a Btu on a stick. Of course, the consumption is with reason. Texas, home to a quarter of the U.S. domestic oil reserves, is also bulging with the second-highest population and a serious petrochemical industry. In recent years, we managed to turn ourselves into the country’s top producer of wind energy. Despite all the chest-thumping that goes on in these parts about those West Texas wind farms (hoist that foam finger!), we are still among the worst in how we use that energy. Though not technically “Southern,” Texans guzzle energy like true rednecks. Each of our homes use, on average, about 14,400 kilowatt hours per year, according to the U.S. Energy Information Administration. It doesn’t all have to do with the A/C, either. Arizonans, generally agreed to be sharing the heat, typically use about 12,000 kWh a year; New Mexicans cruise in at an annual 7,200 kWh. Don’t even get me started on California’s mere 6,000 kWh/year figure.
  • Let’s break down that kilowatt-hour thing. A watt is the energy of one candle burning down. (You didn’t put those matches away, did you?) A kilowatt is a thousand burnin’ candles. And a kilowatt hour? I think you can take it from there. We’re wide about the middle in Bexar, too. The average CPS customer used 1,538 kilowatt hours this June when the state average was 1,149 kWh, according to ERCOT. Compare that with Austin residents’ 1,175 kWh and San Marcos residents’ 1,130 kWh, and you start to see something is wrong. So, we’re wasteful. So what? For one, we can’t afford to be. Maybe back when James Dean was lusting under a fountain of crude we had if not reason, an excuse. But in the 1990s Texas became a net importer of energy for the first time. It’s become a habit, putting us behind the curve when it comes to preparing for that tightening energy crush. We all know what happens when growing demand meets an increasingly scarce resource … costs go up. As the pressure drop hits San Anto, there are exactly two ways forward. One is to build another massively expensive power plant. The other is to transform the whole frickin’ city into a de-facto power plant, where energy is used as efficiently as possible and blackouts simply don’t occur.
  • Consider, South Texas Project Plants 1&2, which send us almost 40 percent of our power, were supposed to cost $974 million. The final cost on that pair ended up at $5.5 billion. If the planned STP expansion follows the same inflationary trajectory, the price tag would wind up over $30 billion. Applications for the Matagorda County plants were first filed with the Atomic Energy Commission in 1974. Building began two years later. However, in 1983 there was still no plant, and Austin, a minority partner in the project, sued Houston Power & Lighting for mismanagement in an attempt to get out of the deal. (Though they tried to sell their share several years ago, the city of Austin remains a 16-percent partner, though they have chosen not to commit to current expansion plans).

  • CPS didn’t just pull nukes out of a hat when it went looking for energy options. CEO Milton Lee may be intellectually lazy, but he’s not stupid. Seeking to fulfill the cheap power mandate in San Antonio and beyond (CPS territory covers 1,566 square miles, reaching past Bexar County into Atascosa, Bandera, Comal, Guadalupe, Kendall, Medina, and Wilson counties), staff laid natural gas, coal, renewables and conservation, and nuclear side-by-side and proclaimed nukes triumphant. Coal is cheap upfront, but it’s helplessly foul; natural gas, approaching the price of whiskey, is out; and green solutions just aren’t ready, we’re told. The 42-member Nuclear Expansion Analysis Team, or NEAT, proclaimed “nuclear is the lowest overall risk considering possible costs and risks associated with it as compared to the alternatives.” Hear those crickets chirping?
  • NEAT members would hold more than a half-dozen closed-door meetings before the San Antonio City Council got a private briefing in September. When the CPS board assembled October 1 to vote the NRG partnership up or down, CPS executives had already joined the application pending with the U.S. Nuclear Regulatory Commission. A Supplemental Participation Agreement allowed NRG to move quickly in hopes of cashing in on federal incentives while giving San Antonio time to gather its thoughts. That proved not too difficult. Staff spoke of “overwhelming support” from the Citizen’s Advisory Board and easy relations with City staff. “So far, we haven’t seen any fatal flaws in our analysis,” said Mike Kotera, executive vice president of energy development for CPS. With boardmember and Mayor Phil Hardberger still in China inspecting things presumably Chinese, the vote was reset for October 29.
  • No one at the meeting asked about cost, though the board did request a month-by-month analysis of the fiasco that has been the South Texas Project 1&2 to be delivered at Monday’s meeting. When asked privately about cost, several CPS officers said they did not know what the plants would run, and the figure — if it were known — would not be public since it is the subject of contract negotiations. “We don’t know yet,” said Bob McCullough, director of CPS’s corporate communications. “We are not making the commitment to build the plant. We’re not sure at this point we really understand what it’s going to cost.” The $206 million outlay the board will consider on Monday is not to build the pair of 1,300-megawatt, Westinghouse Advanced Boiling Water Reactors. It is also not a contract to purchase power, McCullough said. It is merely to hold a place in line for that power.
  • It’s likely that we would come on a recurring basis back to the board to keep them apprised of where we are and also the decision of whether or not we think it makes sense for us to go forward,” said Larry Blaylock, director of CPS’s Nuclear Oversight & Development. So, at what point will the total cost of the new plants become transparent to taxpayers? CPS doesn’t have that answer. “At this point, it looks like in order to meet our load growth, nuclear looks like our lowest-risk choice and we think it’s worth spending some money to make sure we hold that place in line,” said Mark Werner, director of Energy Market Operations.
  • Another $10 million request for “other new nuclear project opportunities” will also come to the board Monday. That request summons to mind a March meeting between CPS officials and Exelon Energy reps, followed by a Spurs playoff game. Chicago-based Exelon, currently being sued in Illinois for allegedly releasing millions of gallons of radioactive wastewater beneath an Illinois plant, has its own nuclear ambitions for Texas. South Texas Project The White House champions nuclear, and strong tax breaks and subsidies await those early applicants. Whether CPS qualifies for those millions remains to be seen. We can only hope.
  • CPS has opted for the Super Honkin’ Utility model. Not only that — quivering on the brink of what could be a substantial efficiency program, CPS took a leap into our unflattering past when it announced it hopes to double our nuclear “portfolio” by building two new nuke plants in Matagorda County. The utility joined New Jersey-based NRG Energy in a permit application that could fracture an almost 30-year moratorium on nuclear power plant creation in the U.S.
  • After Unit 1 came online in 1988, it had to be shut down after water-pump shaft seared off in May, showering debris “all over the place,” according to Nucleonics Week. The next month two breakers failed during a test of backup power, leading to an explosion that sheared off a steam-generator pump and shot the shaft into the station yard. After the second unit went online the next year, there were a series of fires and failures leading to a half-million-dollar federal fine in 1993 against Houston Power. Then the plant went offline for 14 months. Not the glorious launch the partnership had hoped for. Today, CPS officials still do not know how much STP has cost the city, though they insist overall it has been a boon worth billions. “It’s not a cut-and-dried analysis. We’re doing what we can to try to put that in terms that someone could share and that’s a chore,” said spokesman McCollough. CPS has appealed numerous Open Records requests by the Current to the state Attorney General. The utility argues that despite being owned by the City they are not required to reveal, for instance, how much it may cost to build a plant or even how much pollution a plant generates, since the electricity market is a competitive field.
  • How do we usher in this new utopia of decentralized power? First, we have to kill CPS and bury it — or the model it is run on, anyway. What we resurrect in its place must have sustainability as its cornerstone, meaning that the efficiency standards the City and the utility have been reaching for must be rapidly eclipsed. Not only are new plants not the solution, they actively misdirect needed dollars away from the answer. Whether we commit $500 million to build a new-fangled “clean-coal” power plant or choose to feed multiple billions into a nuclear quagmire, we’re eliminating the most plausible option we have: rapid decentralization.
  • A 2003 study at the Massachusetts Institute of Technology estimates the cost of nuclear power to exceed that of both coal and natural gas. A U.S. Energy Information Administration report last year found that will still be the case when and if new plants come online in the next decade. If ratepayers don’t pay going in with nuclear, they can bet on paying on the way out, when virtually the entire power plant must be disposed of as costly radioactive waste. The federal government’s inability to develop a repository for the tens of thousands of tons of nuclear waste means reactors across the country are storing spent fuel in onsite holding ponds. It is unclear if the waste’s lethality and tens of thousands of years of radioactivity were factored into NEAT’s glowing analysis.
  • The federal dump choice, Nevada’s Yucca Mountain, is expected to cost taxpayers more than $60 billion. If it opens, Yucca will be full by the time STP 3&4 are finished, requiring another federal dump and another trainload of greenbacks. Just the cost of Yucca’s fence would set you back. Add the price of replacing a chain-link fence around, let’s say, a 100-acre waste site. Now figure you’re gonna do that every 50 years for 10,000 years or more. Security guards cost extra. That is not to say that the city should skip back to the coal mine. Thankfully, we don’t need nukes or coal, according to the American Council for an Energy-Efficient Economy, a D.C.-based non-profit that champions energy efficiency. A collection of reports released this year argue that a combination of ramped-up efficiency programs, construction of numerous “combined heat and power” facilities, and installation of on-site renewable energy resources would allow the state to avoid building new power plants. Texas could save $73 billion in electric generation costs by spending $50 billion between now and 2023 on such programs, according to the research group. The group also claims the efficiency revolution would even be good for the economy, creating 38,300 jobs. If ACEEE is even mostly right, plans to start siphoning millions into a nuclear reservoir look none too inspired.
  • To jump tracks will take a major conversion experience inside CPS and City Hall, a turning from the traditional model of towering plants, reels of transmission line, and jillions of dependent consumers. CPS must “decentralize” itself, as cities as close as Austin and as far away as Seattle are doing. It’s not only economically responsible and environmentally sound, but it is the best way to protect our communities entering what is sure to be a harrowing century. Greening CPS CPS is grudgingly going greener. In 2004, a team of consultants, including Wisconsin-based KEMA Inc., hired to review CPS operations pegged the utility as a “a company in transition.” Executives interviewed didn’t understand efficiency as a business model. Even some managers tapped to implement conservation programs said such programs were about “appearing” concerned, according to KEMA’s findings.
  • While the review exposed some philosophical shortcomings, it also revealed for the first time how efficiency could transform San Antonio. It was technically possible, for instance, for CPS to cut electricity demand by 1,935 megawatts in 10 years through efficiency alone. While that would be accompanied with significant economic strain, a less-stressful scenario could still cut 1,220 megawatts in that period — eliminating 36 percent of 2014’s projected energy use. CPS’s current plans call for investing $96 million to achieve a 225-megawatt reduction by 2016. The utility plans to spend more than four times that much by 2012 upgrading pollution controls at the coal-fired J.T. Deely power plant.
  • In hopes of avoiding the construction of Spruce 2 (now being built, a marvel of cleanliness, we are assured), Citizen Oversight Committee members asked KEMA if it were possible to eliminate 500 megawatts from future demand through energy efficiency alone. KEMA reported back that, yes, indeed it was possible, but would represent an “extreme” operation and may have “unintended consequences.” Such an effort would require $620 million and include covering 90 percent of the cost of efficiency products for customers. But an interesting thing happens under such a model — the savings don’t end in 2012. They stretch on into the future. The 504 megawatts that never had to be generated in 2012 end up saving 62 new megawatts of generation in 2013 and another 53 megawatts in 2014. With a few tweaks on the efficiency model, not only can we avoid new plants, but a metaphorical flip of the switch can turn the entire city into one great big decentralized power generator.
  • Even without good financial data, the Citizen’s Advisory Board has gone along with the plan for expansion. The board would be “pennywise and pound foolish” not to, since the city is already tied to STP 1&2, said at-large member Jeannie O’Sullivan. “Yes, in the past the board of CPS had been a little bit not as for taking on a [greater] percentage of nuclear power. I don’t know what their reasons were, I think probably they didn’t have a dialogue with a lot of different people,” O’Sullivan said.
  • For this, having a City-owned utility offers an amazing opportunity and gives us the flexibility to make most of the needed changes without state or federal backing. “Really, when you start looking, there is a lot more you can do at the local level,” said Neil Elliott of the ACEEE, “because you control building codes. You control zoning. You can control siting. You can make stuff happen at the local level that the state really doesn’t have that much control of.” One of the most empowering options for homeowners is homemade energy provided by a technology like solar. While CPS has expanded into the solar incentives field this year, making it only the second utility in the state to offer rebates on solar water heaters and rooftop panels, the incentives for those programs are limited. Likewise, the $400,000 CPS is investing at the Pearl Brewery in a joint solar “project” is nice as a white tiger at a truck stop, but what is truly needed is to heavily subsidize solar across the city to help kickstart a viable solar industry in the state. The tools of energy generation, as well as the efficient use of that energy, must be spread among the home and business owners.
  • Joel Serface, with bulb-polished pate and heavy gaze, refers to himself as a “product of the oil shock” who first discovered renewables at Texas Tech’s summer “geek camp.” The possibilities stayed with him through his days as a venture capitalist in Silicon Valley and eventually led him to Austin to head the nation’s first clean-energy incubation center. Serface made his pitch at a recent Solar San Antonio breakfast by contrasting Texas with those sun-worshipping Californians. Energy prices, he says, are “going up. They’re not going down again.” That fact makes alternative energies like solar, just starting to crack the 10-cent-per-killowatt barrier, financially viable. “The question we have to solve as an economy is, ‘Do we want to be a leader in that, or do we want to allow other countries [to outpace us] and buy this back from them?’” he asked.
  • To remain an energy leader, Texas must rapidly exploit solar. Already, we are fourth down the list when it comes not only to solar generation, but also patents issued and federal research awards. Not surprisingly, California is kicking silicon dust in our face.

UPDATE: Extremely High Radiation (20,000 CPM) in Ontario After Rainfall [16Aug11] - 0 views

  • UPDATE: Nine Mile Point 2 nuclear facility shut down twice in 1 week due to a "higher than normal leak".  On August 8th the plant was shut down, then again on August 11th.  Nine Mile Point 2 is situated on Lake Ontario and was leaking into it.  Could that be the source of the extremely high radiation found in Toronto area rainwater? 9wsyr.com (WSYR-TV) -- The Nine Mile Nuclear Plant's unit two is back up and running. The plant needed to be shut down twice this week because of leaks, but Friday night all the repairs were complete.
  • Inspections have assured that there are no other issues and the unit is back up to about 24 percent power.   It will take a little more time to get the unit back up to 100 percent.   Representatives say the leaks were never a risk to the public, or to plant employees.

German Nuclear Decommissioning and Renewables Build-Out [23Oct11] - 0 views

  • Germany will be redirecting its economy towards renewable energy, because of the political decision to decommission its nuclear plants, triggered by the Fukushima event in Japan and subsequent public opposition to nuclear energy. Germany's decision would make achieving its 2020 CO2 emission reduction targets more difficult.   To achieve the CO2 emissions reduction targets and replace nuclear energy, renewable energy would need to scale up from 17% in 2010 to 57% of total electricity generation of 603 TWh in 2020, according to a study by The Breakthrough Institute. As electricity generation was 603 TWh in 2010, increased energy efficiency measures will be required to flat-line electricity production during the next 9 years.   Germany has 23 nuclear reactors (21.4 GW), 8 are permanently shut down (8.2 GW) and 15 (13.2 GW) will be shut down by 2022. Germany will be adding a net of 5 GW of coal plants, 5 GW of new CCGT plants and 1.4 GW of new biomass plants in future years. The CCGT plants will reduce the shortage of quick-ramping generation capacity for accommodating variable wind and solar energy to the grid.
  • Germany is planning a $14 billion build-out of transmission systems for onshore and future offshore wind energy in northern Germany and for augmented transmission with France for CO2-free hydro and nuclear energy imports to avoid any shortages.    Germany had fallen behind on transmission system construction in the north because of public opposition and is using the nuclear plant shutdown as leverage to reduce public opposition. Not only do people have to look at a multitude of 450-ft tall wind turbines, but also at thousands of 80 to 135 ft high steel structures and wires of the transmission facilities.   The $14 billion is just a minor down payment on the major grid reorganization required due to the decommissioning of the nuclear plants and the widely-dispersed build-outs of renewables. The exisitng grid is mostly large-central-plant based. 
  • This article includes the estimated capital costs of shutting down Germany's nuclear plants, reorganizing the grids of Germany and its neighbors, and building out renewables to replace the nuclear energy.    Germany’s Renewable Energy Act (EEG) in 2000, guarantees investors above-market fees for solar power for 20 years from the point of installation. In 2010, German investments in  renewables was about $41.2 billion, of which about $36.1 billion in 7,400 MW of solar systems ($4,878/kW). In 2010, German incentives for all renewables was about $17.9 billion, of which about half was for solar systems.   The average subsidy in 2010 was about ($9 billion x 1 euro/1.4 $)/12 TWh = 53.6 eurocents/kWh; no wonder solar energy is so popular in Germany. These subsidies are rolled into electric rates as fees or taxes, and will ultimately make Germany less competitive in world markets.   http://thebreakthrough.org/blog//2011/06/analysis_germanys_plan_to_phas-print.html http://mobile.bloomberg.com/news/2011-05-31/merkel-faces-achilles-heel-in-grids-to-unplug-german-nuclear.html http://www.theecologist.org/News/news_analysis/829664/revealed_how_your_country_compares_on_renewable_investment.html http://en.wikipedia.org/wiki/Solar_power_in_Germany

  • SUMMARY OF ESTIMATED CAPITAL AND OTHER COSTS   The estimated capital costs and other costs for decommissioning the nuclear plants, restoring the sites, building out renewables, wind and solar energy balancing plants, and reorganizing electric grids over 9 years are summarized below.    The capital cost and subsidy cost for the increased energy efficiency measures was not estimated, but will likely need to be well over $180 billion over 9 years, or $20 billion/yr, or $20 b/($3286 b in 2010) x 100% = 0.6% of GDP, or $250 per person per yr.     Decommission nuclear plants, restore sites: 23 @ $1 billion/plant = $23 billion Wind turbines, offshore: 53,300 MW @ $4,000,000/MW = $213.2 billion   Wind turbines, onshore: 27,900 MW @ $2,000,000/MW = $55.8 billion Wind feed-in tariff extra costs rolled into electric rates over 9 years: $200 billion  Solar systems: 82,000 MW @ $4,500,000/MW = $369 billion Solar feed-in tariff extra costs rolled into electric rates over 9 years = $250 billion. Wind and solar energy balancing plants: 25,000 MW of CCGTs @ $1,250,000/MW = $31.3 billion Reorganizing European elecric grids tied to German grids: $150 billion
  • RENEWABLE ENERGY AND ENERGY EFFICIENCY TARGETS   In September 2010 the German government announced the following targets:   Renewable electricity - 35% by 2020 and 80% by 2050 Renewable energy - 18% by 2020, 30% by 2030, and 60% by 2050 Energy efficiency - Reducing the national electricity consumption 50% below 2008 levels by 2050.  http://en.wikipedia.org/wiki/Renewable_energy_in_Germany   Germany has a target to reduce its nation-wide CO2 emissions from all sources by 40% below 1990 levels by 2020 and 80-85% below 1990 levels by 2050. That goal could be achieved, if 100% of electricity is generated by renewables, according to Mr. Flasbarth. Germany is aiming to convince the rest of Europe to follow its lead.
  • A 2009 study by EUtech, engineering consultants, concluded Germany will not achieve its nation-wide CO2 emissions target; the actual reduction will be less than 30%. The head of Germany's Federal Environment Agency (UBA), Jochen Flasbarth, is calling for the government to improve CO2 reduction programs to achieve targets. http://www.spiegel.de/international/germany/0,1518,644677,00.html   GERMAN RENEWABLE ENERGY TO-DATE   Germany announced it had 17% of its electrical energy from renewables in 2010; it was 6.3% in 2000. The sources were 6.2% wind, 5.5% biomass, 3.2% hydro and 2.0% solar. Electricity consumption in 2010 was 603 TWh (production) - 60 TWh (assumed losses) = 543 TWh http://www.volker-quaschning.de/datserv/ren-Strom-D/index_e.php  
  • Wind: At the end of 2010, about 27,200 MW of onshore and offshore wind turbines was installed in Germany at a capital cost of about $50 billion. Wind energy produced was 37.5 TWh, or 6.2% of total production. The excess cost of the feed-in-tariff energy bought by utilities and rolled into electricity costs of rate payers was about $50 billion during the past 11 years.   Most wind turbines are in northern Germany. When wind speeds are higher wind curtailment of 15 to 20 percent takes place because of insufficient transmission capacity and quick-ramping gas turbine plants. The onshore wind costs the Germany economy about 12 eurocent/kWh and the offshore wind about 24 eurocent/kWh. The owners of the wind turbines are compensated for lost production.   The alternative to curtailment is to “sell” the energy at European spot prices of about 5 eurocent/kWh to Norway and Sweden which have significant hydro capacity for balancing the variable wind energy; Denmark has been doing it for about 20 years.   As Germany is very marginal for onshore wind energy (nation-wide onshore wind CF 0.167) and nearly all of the best onshore wind sites have been used up, or are off-limits due to noise/visual/environmental impacts, most of the additional wind energy will have to come from OFFSHORE facilities which produce wind energy at about 2 to 3 times the cost of onshore wind energy. http://theenergycollective.com/willem-post/61774/wind-energy-expensive
  • Biomass: At the end of 2010, about 5,200 MW of biomass was installed at a capital cost of about $18 billion. Biomass energy produced was 33.5 TWh, or 5.5% of production. Plans are to add 1,400 MW of biomass plants in future years which, when fully implemented, would produce about 8.6 TWh/yr.   Solar: At the end of 2010, about 17,320 MW of PV solar was installed in Germany at a capital cost of about $100 billion. PV solar energy produced was 12 TWh, or 2% of total production. The excess cost of the feed-in-tariff energy bought by utilities and rolled into the electricity costs of rate payers was about $80 billion during the past 11 years.   Most solar panels are in southern Germany (nation-wide solar CF 0.095). When skies are clear, the solar production peaks at about 7 to 10 GW. Because of insufficient capacity of transmission and quick-ramping gas turbine plants, and because curtailment is not possible, part of the solar energy, produced at a cost to the German economy of about 30 to 50 eurocent/kWh is “sold” at European spot prices of about 5 eurocent/kWh to France which has significant hydro capacity for balancing the variable solar energy. http://theenergycollective.com/willem-post/46142/impact-pv-solar-feed-tariffs-germany  
  • Hydro: At the end of 2010, about 4,700 MW of hydro was installed. Hydro energy produced was 19.5 TWh, or 3.2% of production. Hydro growth has been stagnant during the past 20 years. See below website.   As it took about $150 billion of direct investment, plus about $130 billion excess energy cost during the past 11 years to achieve 8.2% of total production from solar and wind energy, and assuming hydro will continue to have little growth, as was the case during the past 20 years (almost all hydro sites have been used up), then nearly all of the renewables growth by 2020 will be mostly from wind, with the remainder from solar and biomass. http://www.renewableenergyworld.com/rea/news/article/2011/03/new-record-for-german-renewable-energy-in-2010??cmpid=WNL-Wednesday-March30-2011   Wind and Solar Energy Depend on Gas: Wind and solar energy is variable and intermittent. This requires quick-ramping gas turbine plants to operate at part-load and quickly ramp up with wind energy ebbs and quickly ramp down with wind energy surges; this happens about 100 to 200 times a day resulting in increased wear and tear. Such operation is very inefficient for gas turbines causing them to use extra fuel/kWh and emit extra CO2/kWh that mostly offset the claimed fuel and CO2 reductions due to wind energy. http://theenergycollective.com/willem-post/64492/wind-energy-reduces-co2-emissions-few-percent  
  • Wind energy is often sold to the public as making a nation energy independent, but Germany will be buying gas mostly from Russia supplied via the newly constructed pipeline under the Baltic Sea from St. Petersburg to Germany, bypassing Poland.   GERMANY WITHOUT NUCLEAR ENERGY   A study performed by The Breakthrough Institute concluded to achieve the 40% CO2 emissions reduction target and the decommissioning of 21,400 MW of nuclear power plants by 2022, Germany’s electrical energy mix would have to change from 60% fossil, 23% nuclear and 17% renewables in 2010 to 43% fossil and 57% renewables by 2020. This will require a build-out of renewables, reorganization of Europe’s electric grids (Europe’s concurrence will be needed) and acceleration of energy efficiency measures.   According to The Breakthrough Institite, Germany would have to reduce its total electricity consumption by about 22% of current 2020 projections AND achieve its target for 35% electricity generated from renewables by 2020. This would require increased energy efficiency measures to effect an average annual decrease of the electricity consumption/GDP ratio of 3.92% per year, significantly greater than the 1.47% per year decrease assumed by the IEA's BAU forecasts which is based on projected German GDP growth and current German efficiency policies.
  • The Breakthrough Institute projections are based on electricity consumption of 544  and 532 TWh  in 2008 and 2020, respectively; the corresponding production is 604 TWh in 2008 and 592 TWh in 2020.   http://thebreakthrough.org/blog//2011/06/analysis_germanys_plan_to_phas-print.html http://www.iea.org/textbase/nppdf/free/2007/germany2007.pdf   Build-out of Wind Energy: If it is assumed the current wind to solar energy ratio is maintained at 3 to 1, the wind energy build-out will be 80% offshore and 20% onshore, and the electricity production will be 592 TWh, then the estimated capital cost of the offshore wind turbines will be [{0.57 (all renewables) - 0.11 (assumed biomass + hydro)} x 592 TWh x 3/4] x 0.8 offshore/(8,760 hr/yr x average CF 0.35) = 0.0533 TW offshore wind turbines @ $4 trillion/TW = $213 billion and of the onshore wind turbines will be [{0.57 (all renewables) - 0.11 (assumed biomass + hydro)} x 592 TWh x 3/4] x 0.2 onshore/(8,760 hr/yr x average CF 0.167) = 0.279 TW of wind turbines @ $2 trillion/TW = $56 billion, for a total of $272 billion. The feed in tariff subsidy for 9 years, if maintained similar to existing subsidies to attract adequate capital, will be about $150 billion offshore + $50 billion onshore, for a total of $200 billion.    
  • Note: The onshore build-out will at least double Germany’s existing onshore wind turbine capacity, plus required transmission systems; i.e., significant niose, environmental and visual impacts over large areas.   Recent studies, based on measured, real-time, 1/4-hour grid operations data sets of the Irish, Colorado and Texas grids, show wind energy does little to reduce CO2 emissions. Such data sets became available during the past 2 to 3 years. Prior studies, based on assumptions, estimates, modeling scenarios, and statistics, etc., significantly overstate CO2 reductions.  http://theenergycollective.com/willem-post/64492/wind-energy-reduces-co2-emissions-few-percent   Build-out of PV Solar Energy: The estimated capital cost of the PV solar capacity will be [{0.57 (all renewables) - 0.11 (assumed biomass + hydro)} x 592 TWh x 1/4]/(8,760 hr/yr x average CF 0.095) = 0.082 TW @ $4.5 trillion/TW = $369 billion. The feed in tariff subsidy, if maintained similar to existing subsidies to attract adequate capital, will be about $250 billion.   Reorganizating Electric Grids: For GW reasons, a self-balancing grid system is needed to minimize CO2 emissions from gas-fired CCGT balancing plants. One way to implement it is to enhance the interconnections of the national grids with European-wide HVDC overlay systems (owning+O&M costs, including transmission losses), and with European-wide selective curtailment of wind energy, and with European-wide demand management and with pumped hydro storage capacity. These measures will reduce, but not eliminate, the need for balancing energy, at greater wind energy penetrations during high-windspeed weather conditions, as frequently occur in Iberia (Spain/Portugal).  
  • European-wide agreement is needed, the capital cost will be in excess of $150 billion and the adverse impacts on quality of life (noise, visuals, psychological), property values and the environment will be significant over large areas.    Other Capital Costs: The capacity of the quick-ramping CCGT balancing plants was estimated at 25,000 MW; their capital cost is about 25,000 MW x $1,250,000/MW = $31.3 billion. The capital costs of decommissioning and restoring the sites of the 23 nuclear plants will be about $23 billion.   Increased Energy Efficiency: Increased energy efficiency would be more attractive than major build-outs of renewables, because it provides the quickest and biggest "bang for the buck", AND it is invisible, AND it does not make noise, AND it has minimal environmental impact, AND it usually reduces at least 3 times the CO2 per invested dollar, AND it usually creates at least 3 times the jobs per invested dollar, AND it usually creates at least 3 times the energy reduction per invested dollar, AND it does all this without public resistance and controversy.   Rebound, i.e., people going back to old habits of wasting energy, is a concept fostered by the PR of proponents of conspicuous consumption who make money on such consumption. People with little money love their cars getting 35-40 mpg, love getting small electric and heating bills. The rebound is mostly among people who do not care about such bills.
  • A MORE RATIONAL APPROACH   Global warming is a given for many decades, because the fast-growing large economies of the non-OECD nations will have energy consumption growth far outpacing the energy consumption growth of the slow-growing economies of the OECD nations, no matter what these OECD nations do regarding reducing CO2 emissions of their economies.   It is best to PREPARE for the inevitable additional GW by requiring people to move away from flood-prone areas (unless these areas are effectively protected, as in the Netherlands), requiring new  houses and other buildings to be constructed to a standard such as the Passivhaus standard* (such buildings stay cool in summer and warm in winter and use 80 to 90 percent less energy than standard buildings), and requiring the use of new cars that get at least 50 mpg, and rearranging the world's societies for minimal energy consumption; making them walking/bicycling-friendly would be a good start.   If a nation, such as the US, does not do this, the (owning + O&M) costs of its economy will become so excessive (rising resource prices, increased damage and disruptions from weather events) that its goods and services will become less competitive and an increasing percentage of its population will not be able to afford a decent living standard in such a society.   For example: In the US, the median annual household income (inflation-adjusted) was $49,445, a decline of 7% since 2000. As the world’s population increases to about 10 billion by 2050, a triage-style rationing of resources will become more prevalent. http://www.usatoday.com/news/nation/story/2011-09-13/census-household-income/50383882/1
  • * A 2-year-old addition to my house is built to near-Passivhaus standards; its heating system consists of a thermostatically-controlled 1 kW electric heater, set at 500 W, that cycles on/off on the coldest days for less than 100 hours/yr. The addition looks inside and out entirely like standard construction. http://theenergycollective.com/willem-post/46652/reducing-energy-use-houses

#Fukushima I Nuke Plant: Full of Untrained, Migrant Workers, TEPCO Says Subcontractors ... - 0 views

  • Tokyo Shinbun is a regional newspaper covering Kanto region of Japan. It has been reporting on the Fukushima accident and resultant radiation contamination in a more honest and comprehensive manner than any national newspaper. (Their only shortcoming is that their links don't seem to last for more than a week.)Their best coverage on the subject, though, is not available digitally but only in the printed version of the newspaper. But no worry, as there is always someone who transcribes the article and post it on the net for anyone to see.
  • In the 2nd half of the January 27 article, Tokyo Shinbun details what kind of workers are currently working at Fukushima I Nuclear Power Plant: migrant workers young (in their 20's) and not so young (in their 60's), untrained, $100 a day. Some of them cannot even read and write.
  • However, the workers voice concerns over the safety management. One of the subcontract workers told the newspaper:
  • ...17 more annotations...
  • Low wages
  • The relationship between the cause of Mr. Osumi's death and radiation exposure is unknown. However, it is still the radiation exposure that is most worrisome for the workers who work at Fukushima I Nuke Plant to wind down the accident. The radiation exposure limit was lowered back to the normal "maximum 50 millisieverts per year" and "100 millisieverts in 5 years" on December 16 last year. It was done on the declaration of "the end of the accident" by Prime Minister Noda that day.
  • The radiation exposure limit was raised to 250 millisieverts per year right after the accident, as a special measure. The Ministry of Health and Labor argued that the number was based on the international standard for a severe accident which was 500 millisieverts. But the real purpose was to increase the number of hours that can be put in by the workers and to increase the number of workers to promptly wind down the accident.
  • However, as the prime minister wanted to appeal "the end of the accident", the limit was lowered back to the normal limit.
  • According to TEPCO, the radiation exposure levels of workers exceeded [annualized?] 250 millisieverts in some cases right after the accident, but since April it has been within 100 millisieverts.
  • Right now, 70% of workers at the plant are migrant contract workers from all over Japan. Most of them have never worked at nuke plants before. The pay is 8000 yen to 13,000 yen [US$104 to $170] per day. Most of them are either in their 20s who are finding it difficult to land on any job, or in their 60s who have "graduated" from the previous jobs."
  • He also says the safety management cannot be fully enforced by TEPCO alone, and demands the national government to step in. "They need to come up with the management system that include the subcontract workers. Unless they secure the [safe] work environment and work conditions, they cannot deal with the restoration work that may continue for a long while."
  • As to the safety management, he said, "Before you start working at a nuclear power plant, you have to go through the "training before entering radiation control area". But in reality the training is ceremonial. The assumptions in the textbook do not match the real job site in an emergency situation. There were some who could not read, but someone else filled in the test for them at the end of the training."
  • Then the workers start working at the site. But there are not enough radiation control personnel who measure radiation levels in the high-radiation locations, and warn and instruct the workers. There are too many workers because the nature of the work is to wind down the accident. There are workers who take off their masks or who smoke even in the dangerous [high radiation] locations. I'm worried for their internal radiation exposures."
  • In the rest area where the workers eat lunch and smoke, the radiation level is 12 microsieverts/hour. "Among workers, we don't talk about radiation levels. There's no point."
  • The worker divulged to us, "For now, they've managed to get workers from all over Japan. But there won't be enough workers by summer, all bosses at the employment agencies say so." Local construction companies also admit [to the scarcity of workers by summer.]
  • "Local contractors who have been involved in the work at Fukushima I Nuclear Power Plant do not work there any more. It's dangerous, and there are jobs other than at the nuke plant, such as construction of temporary housing. The professional migrant workers who hop from one nuclear plant to another all over Japan avoid Fukushima I Nuke Plant. The pay is not particularly good, so what is the point of getting high radiation to the max allowed and losing the opportunity to work in other nuclear plants? So, it's mostly amateurs who work at the plant right now. Sooner or later, the supply of workers will dry up."
  • As to the working conditions and wage levels of the subcontract workers, TEPCO's PR person explains, "We believe the subcontracting companies are providing appropriate guidance." As to securing the workers, he emphasizes that "there is no problem at this point in sourcing enough workers. We will secure necessary workers depending on how the work progresses."
  • However, Katsuyasu Iida, Director General of Tokyo Occupational Safety and Health Center who have been dealing with the health problems of nuclear workers, points out, "Workers are made to work in a dangerous environment. The wage levels are going down, and there are cases of non-payment. It is getting harder to secure the workers."
  • From Tokyo Shinbun (1/27/2012):(The first half of the article is asbout Mr. Osumi, the first worker to die in May last year after the plant "recovery" work started. About him and his Thai wife, please read my post from July 11, 2011.)
  • Memo from the desk [at Tokyo Shinbun]: Workers at Fukushima I Nuke Plant are risking their lives. Some are doing it for 8000 yen per day. A councilman who also happens to work for TEPCO earns more than 10 million yen [US$130,000] per year. Executives who "descended from heaven" to cushy jobs in the "nuclear energy village" are alive and well. To move away from nuclear power generation is not just about energy issues. It is to question whether we will continue to ignore such "absurdity".
  • Well said. Everybody in the nuclear industry in Japan knew that the industry depended (still does) on migrant workers who were (still are) hired on the cheap thorough layer after layer of subcontracting companies. Thanks to the Fukushima I Nuclear Plant accident, now the general public know that. But there are plenty of those who are still comfortable with the nuclear power generated by the nuclear power plants maintained at the expense of such workers and see nothing wrong with it.

San Onofre nuclear power plant unit shut down after potential leak [30Jan12] - 0 views

  • Officials at the San Onofre nuclear power plant shut down one of the facility's two units Tuesday evening after a sensor detected a possible leak in a steam generator tube.The potential leak was detected about 4:30 p.m., and the unit was completely shut down about an hour later, Southern California Edison said. "The potential leak poses no imminent danger to the plant workers or the public," utility spokeswoman Jennifer Manfre told The Times. She said there were no evacuations and that crews were assessing the situation to determine if a leak had occurred.

Greg Palast » Fukushima: They Knew [10Nov11] - 0 views

  • Here was the handwritten log kept by a senior engineer at the nuclear power plant:
  • Wiesel was very upset. He seemed very nervous. Very agitated. . . . In fact, the plant was riddled with problems that, no way on earth, could stand an earth- quake. The team of engineers sent in to inspect found that most of these components could "completely and utterly fail" during an earthquake. "Utterly fail during an earthquake." And here in Japan was the quake and here is the utter failure. The warning was in what the investigations team called The Notebook, which I'm not supposed to have.  Good thing I've kept a copy anyway, because the file cabinets went down with my office building .... WORLD TRADE CENTER TOWER 1, FIFTY-SECOND FLOOR
  • [This is an excerpt in FreePress.org from Vultures' Picnic: In Pursuit of Petroleum Pigs, Power Pirates and High-Finance Fraudsters, to be released this Monday.  Click here to get the videos and the book.] Two senior nuclear plant engineers were spilling out their souls and files on our huge conference table, blowing away my government investigations team with the inside stuff about the construction of the Shoreham, New York, power station. The meeting was secret. Very secret. Their courage could destroy their careers: No engineering firm wants to hire a snitch, even one who has saved thousands of lives. They could lose their jobs; they could lose everything. They did. That’s what happens. Have a nice day.

  • On March 12 this year, as I watched Fukushima melt, I knew:  the "SQ" had been faked.  Anderson Cooper said it would all be OK.  He'd flown to Japan, to suck up the radiation and official company bullshit.  The horror show was not the fault of Tokyo Electric, he said, because the plant was built to withstand only an 8.0 earthquake on the Richter scale, and this was 9.0.  Anderson must have been in the gym when they handed out the facts.  The 9.0 shake was in the middle of the Pacific Ocean, 90 miles away.  It was barely a tenth of that power at Fukushima. I was ready to vomit.  Because I knew who had designed the plant, who had built it and whom Tokyo Electric Power was having rebuild it:  Shaw Construction.  The latest alias of Stone & Webster, the designated builder for every one of the four new nuclear plants that the Obama Administration has approved for billions in federal studies.
  • But I had The Notebook, the diaries of the earthquake inspector for the company.  I'd squirreled it out sometime before the Trade Center went down.  I shouldn't have done that.  Too bad. All field engineers keep a diary. Gordon Dick, a supervisor, wasn’t sup- posed to show his to us. I asked him to show it to us and, reluctantly, he directed me to these notes about the “SQ” tests.
  • SQ is nuclear-speak for “Seismic Qualification.” A seismically qualified nuclear plant won’t melt down if you shake it. A “seismic event” can be an earthquake or a Christmas present from Al Qaeda. You can’t run a nuclear reactor in the USA or Europe or Japan without certified SQ. This much is clear from his notebook: This nuclear plant will melt down in an earthquake. The plant dismally failed to meet the Seismic I (shaking) standards required by U.S. and international rules.
  • From The Notebook: Wiesel was very upset. He seemed very nervous. Very agitated. [He said,] “I believe these are bad results and I believe it’s reportable,” and then he took the volume of federal regulations from the shelf and went to section 50.55(e), which describes reportable deficiencies at a nuclear plant and [they] read the section together, with Wiesel pointing to the appropriate paragraphs that federal law clearly required [them and the company] to report the Category II, Seismic I deficiencies. Wiesel then expressed his concern that he was afraid that if he [Wiesel] reported the deficiencies, he would be fired, but that if he didn’t report the deficiencies, he would be breaking a federal law. . . . The law is clear. It is a crime not to report a safety failure. I could imagine Wiesel standing there with that big, thick rule book in his hands, The Law. It must have been heavy. So was his paycheck. He weighed the choices: Break the law, possibly a jail-time crime, or keep his job.
  • I think we should all worry about Bob. The company he worked for, Stone & Webster Engineering, built or designed about a third of the nuclear plants in the United States.

US Radiation Monitoring May Have Been Handed Off To Nuclear Industry [04Nov11] Lobbyist... - 0 views

  • Lucas W Hixson may have uncovered a major abuse of the public trust by the NRC. In late March 2011 the NRC issued a directive that allowed the nuclear industry lobbyist group NEI to supply radiation monitoring data to the NRC who would then forward it to the EPA. March 24th the NRC discussed handing over radiation monitoring to nuclear industry lobbyists, April 14th RadNet was shut down and went back to routine monitoring schedules. This meant no ongoing food,water and air filter testing. Only the radiation level monitors were left operating. The EPA claimed that levels were going down as the reason for shutting down the expanded monitoring, but places like Idaho did not have the decreases seen at other sites.
  • The NRC directive put commercial nuclear power plant owners in charge of voluntarily providing the public with radiation monitoring data but it would be run through their nuclear industry lobbyists before it would then be provided to the NRC. Raw data was not provided directly to the NRC. Considering the massive US nuclear industry offensive to flood the media with propaganda downplaying the Fukushima nuclear disaster, they are hardly a reliable source to tell the public what the radiation levels are.
  • RadNet itself had many problems, stations didn’t work, some were not calibrated before the disaster. Even more disturbing is that the EPA does not even handle their own radiation monitoring network. The important function falls to a former Bush administration appointee running a business out of a rundown storefront in New Mexico. Under a $238,000 no bid contract Environmental Dimensions supposedly manages, maintains and operates RadNet, the only tool the public has to see if we are being subjected to nuclear fallout. The blogger that broke this story states that Environmental Dimensions has tripled their revenue in recent years. The company cites a different address as their mailing address. This shows up as a tiny house in Albuquerque. EDI was also part of a 12 million dollar contract in 2010 along with a couple of other contractors. The contract provides environmental & remediation services to the US Corps of Engineers. EDI claims to have been in business since 1990 but owner, Ms. Bradshaw worked for the DoD in 2006.

  • What little system the public has for radiation notification through the EPA has been shuffled off to a no bid contract with spurious origins and the system experienced widespread problems when it was needed most. That system was mostly turned off just over a month after the disaster. The NRC, the agency tasked with protecting the public from nuclear disasters decided to hand everything over to the nuclear industry’s lobbyists.

Fast reactor advocates throw down gauntlet to MIT authors[24Jul11] - 0 views

  • Near the end of 2010, the Massachusetts Institute of Technology released a summary of a report titled The Future of the Nuclear Fuel Cycle as part of its MIT Energy Initiative. The complete report was released a few months ago. The conclusions published that report initiated a virtual firestorm of reaction among the members of the Integral Fast Reactor (IFR) Study group who strongly disagreed with the authors.
  • the following quote from the “Study Context” provides a good summary of why the fast reactor advocates were so dismayed by the report.
  • For decades, the discussion about future nuclear fuel cycles has been dominated by the expectation that a closed fuel cycle based on plutonium startup of fast reactors would eventually be deployed. However, this expectation is rooted in an out-of-date understanding about uranium scarcity. Our reexamination of fuel cycles suggests that there are many more viable fuel cycle options and that the optimum choice among them faces great uncertainty—some economic, such as the cost of advanced reactors, some technical such as implications for waste management, and some societal, such as the scale of nuclear power deployment and the management of nuclear proliferation risks. Greater clarity should emerge over the next few decades, assuming that the needed research is carried out for technological alternatives and that the global response to climate change risk mitigation comes together. A key message from our work is that we can and should preserve our options for fuel cycle choices by continuing with the open fuel cycle, implementing a system for managed LWR spent fuel storage, developing a geological repository, and researching technology alternatives appropriate to a range of nuclear energy futures.

  • The group of fast reactor supporters includes some notable scientists and engineers whose list of professional accomplishments is at least as long as those of the people who produced the MIT report. In addition, it includes people like Charles Till and Yoon Chang who were intimately involved in the US’s multi-decade long fast reactor development and demonstration program that resulted in demonstrating a passively safe, sodium cooled reactor and an integral recycling system based on metallic fuel and pyroprocessing.
  • That effort, known as the Integral Fast Reactor, was not just based on an out-dated concept of uranium availability, but also on the keen recognition that the public wants a clear solution to “the nuclear waste issue” that does not look like a decision to “kick the can down the road.”
  • he Science Council for Global Initiatives produced a detailed critique of the MIT paper and published that on Barry Brook’s Brave New Climate blog at the end of May 2011. The discussion has a great deal of interest for technical specialists and is supporting evidence that belies the often asserted falsehood (by people who oppose nuclear technology) that the people interested in developing and deploying nuclear technology speak with a single, almost brainwashed voice.
  • In recent days, however, the controversy has become more interesting because the IFR discussion group has decided to issue a public debate challenge and to allow people like me to write about that challenge in an attempt to produce some response.
  • I think your team is dead wrong on your conclusion that we don’t need fast reactors/closed fuel cycle for decades.Your study fails to take into account the political landscape the competitive landscape the safety issue environmental issues with uranium miningIt is unacceptable to the public to not have a solution to the waste issue. Nuclear power has been around for over 50 years, and we STILL HAVE NO OPTION FOR THE WASTE today other than interim dry cask storage. There is no national repository. Without that, the laws in my state forbid construction of a new nuclear power plant.
  • Other countries are pursuing fast reactors, we are not. Russia has 30 years of commercial operating history with fast reactors. The US has zero.We invented the best Gen IV technology according to the study done by the Gen IV International Forum. So what did we do with it? After spending $5B on the project, and after proving it met all expectations, we CANCELLED it (although the Senate voted to fund it).
  • An average investment of $300M a year could re-start our fast reactor program with a goal of actually commercializing our best reactor design (the IFR according the GIF study).
  • At least we’d have a bird in the hand that we know works, largely solves the waste problem, since the fast reactor waste needs only to be stored for a few hundred years at most, and doesn’t require electric power or any active systems to safely shut down.
  • Investing lots of money in a project and pulling the funding right before completion is a bad strategy for technology leadership.
  • MIT should be arguing for focusing and finishing what we started with the IFR. At least we’d have something that addresses safety, waste, and environmental issues. Uranium is cheap because we don’t have to pay for the environmental impact of uranium mining.

Questions of Competence at Ft. Calhoun Plant [25sep11] - 0 views

  • The switch — one that's tripped when Fort Calhoun Nuclear Station needs to safely shut down its reactor — was making an unusual buzzing sound.Plant engineers looked into it, made some repairs and overall didn't think it was a big deal.Turns out they didn't understand the problem as well as they thought they did. During a later test, the switch malfunctioned.
  • The kind of thinking that led to the switch failure at the nuclear power plant 19 miles north of Omaha has now landed the plant in some hot water with federal regulators. More than a mechanical failing, it suggests a culture that's out of step with the assume-nothing, take-no-chances, stay-on-top-of-things approach that's demanded when working with a technology where multiple errors and failures can cascade into very, very bad results. The switch issue came on the heels of another regulatory write-up Fort Calhoun had received for having inadequate plans for dealing with extremely massive flooding — flooding even greater than the historic high water levels seen at the plant this summer.
  • Fort Calhoun is one of only two out of the nation's 104 nuclear reactors currently on the U.S. Nuclear Regulatory Commission's list of most-troubled plants, and one of only eight to land on it over the past decade.It's all caused a great deal of introspection within the plant's owner, the Omaha Public Power District. While the utility's top leaders say the plant remains a safe one, in hindsight they say the staff's safety focus had slipped."We had a slow, subtle decline,'' Gary Gates, OPPD's president and CEO, said in an interview during a plant visit last week. "This plant is used to running at a high level of performance. We're embarrassed to be in this situation. This is not how Fort Calhoun runs.

  • Gates said he and OPPD are committed to making any changes necessary to restore the NRC's confidence, and he hasn't ruled out management changes. He believes the plant and its 700 workers will emerge in the end stronger and more focused.Despite the regulatory issues, the plant that typically provides almost one-sixth of the electricity powering lights, TVs and toasters in the Omaha area is preparing to resume operations later this fall after months in a flood-related shutdown mode.
  • The NRC, OPPD and nuclear power experts all say that the public has nothing to fear from Fort Calhoun's troubles or the restarting of its reactor. They say U.S. nuclear plants are engineered and scrutinized in ways intended to ensure they never reach the point of catastrophe.Take, for example, that recent switch failure. There are three identical switches that perform the same function at Fort Calhoun, a multiple redundancy built in just in case of such a problem, with two needing to work to shut down the reactor.And operators also have five different ways they can shut it down manually. They train on each method several times a year in a simulator that is identical to the plant's actual control room, right down to the shade of carpeting.

Hurricane Irene shuts down US nuclear reactors [29Aug11] - 0 views

  • A nuclear reactor in Maryland has been shut down because of wind damage, while others were either taken offline or operating at reduced capacity as precautionary measures before the arrival of hurricane Irene on Sunday.A reactor at the Calvert Cliffs nuclear plant in Lusby, Maryland, remained off-line on Sunday, after going into automatic shutdown when a piece of aluminum siding ripped from a nearby building damaged a transformer.Constellation Energy, which operates the Lusby plant, said the facility was safe and that a second reactor was operating at full capacity. No power outages were expected because of the shutdown.
  • Maryland state emergency agency said the plant would reopen after inspection. "Number one will stay offline until they have folks that will crawl over every inch of it," its spokesman, Quentin Banks said.It was the second complete shutdown caused by Irene, after authorities took a plant offline in New Jersey as a precaution before the storm.Exelon Corporation decided on Saturday afternoon to take its Oyster Creek generator offline as Irene blew in. "It's really as a precaution, a conservative action, because we do expect hurricane force winds," Marshall Murphy, an Exelon spokesman, told reporters.
  • Fourteen nuclear plants from North Carolina to New Hampshire were in Irene's path

The Hindu :AEC chief puts odds of N-plant accidents at '1-in-infinity' [10Nov11] - 0 views

  • The probability of an accident due to a nuclear plant is one is to infinity and all atomic power plants in the country conform to safety standards, chairman of Atomic Energy Commission Srikumar Banerjee said on Thursday. “At least 1.75 lakh people die due to road accidents in a single year whereas there are nearly 14,000 nuclear plants in the world and the casualty rate till date is just 52,” Dr. Banerjee told reporters on the sidelines of the golden jubilee celebrations of Terminal Ballistic Research Laboratory (TBRL) at Ramgarh, near Chandigarh. Pointing out that no human activity can be risk-free, he said there was a definite need for creating awareness and programmes should to be intensified to convince the people in the neighbourhood of a proposed or existing nuclear plant. He said human body faces more radiation during a CT scan than working in a nuclear power plant.
  • Referring to the recent Fukushima nuclear accident, Dr. Banerjee said it happened after a gap of 25 years and the cause and effect of the accident was earthquake followed by a tsunami. “It was not a nuclear accident... immediately after the earthquake, the nuclear reactor shut down and nuclear chain reaction stopped,” he said adding it was a complete station blackout as the decay heat produced in the plant could not be taken out. He, however, said the total casualty due to the nuclear accident was zero. “The spread of radiation was not as high as it was projected,” he said talking about the nuclear accident in Japan. After a nuclear reactor is shut down the energy level comes down to around 2 per cent from 100 per cent due to heat decay, Dr. Banerjee said. He, however, exuded confidence all nuclear plants in the country are safe and conform to the standards of Atomic Energy Regulatory Board and are taken care of by Nuclear Power Corporation. “India too experienced earthquakes and tsunami in the past but there was no nuclear accident as the nuclear plants had all the gadgets to give signal much in advance,” he said. Dr. Banerjee rejected that alarm bells had rung in India after the Japanese nuclear accident. “All steps needed for safety and security for nuclear plants have been taken by Nuclear Power Corporation,” he added.
  • He, however, stressed that it was necessary to strengthen the mechanism in the passive cooling system in nuclear plants in India. In the passive cooling system, heat can be taken out from the plant. Responding to a query regarding protests by habitants before setting up a nuclear plant in their neighbourhood, he said what is needed is to explain things to local people in simple local language and also convince them what actually the plant is. After land acquisition, a package must be given to the affected people and at all costs excellent relationship is needed with people living around the plant. He termed it as “baseless,” the allegation that nuclear radiation comes out from the nuclear plant. Besides, the plants along the coastal areas do not have any effect on the lives of fish, he added.

Warm water in Sound causes MillstoneNuclear Power Stationt to shut down [13Aug12] - 0 views

  • For the first time, record-breaking water temperatures in Long Island Sound have forced the shutdown of the Unit 2 nuclear reactor at the Millstone Power Station.
  • It appears to be the only nuclear power plant in the nation forced to shut down this summer due to high water temperatures, said Neil Sheehan, spokesman for the Nuclear Regulatory Commission. This is the first time Unit 2 has been shut due to high water temperature since it began operations in 1975, according to Ken Holt, spokesman for Millstone owner Dominion.

Japan's Nukes Following Earthquake - 1 views

  • TEPCO has just released "diaries" from early in the accident giving us a better view of the sequence of events from the operators point of view.
  • The bulk of the materials, distributed on discs with digital files, show reams of raw numerical data. They include photos of broadsheet computer printouts and other formatted charts with thousands of data points for measurements of reactor heat, pressure, water levels, fuel rod positions and the status of cooling pumps, among other functions. Tokyo Electric, or Tepco, also released a smaller batch of more recent documents highlighting its various efforts to restore electric power to each of the reactors, a task that was achieved on April 26. But a series of what Tepco terms reactor "diaries" from the first 48 hours after the quake include the most visually arresting materials. These feature snapshots of whiteboards on which plant employees—11 of whom remained in each of the plant's three control rooms—jotted down status updates on the progress of the reactor shutdowns and steadily increasing radiation levels around the facility.
  • Using red, black or blue ink markers, the plant operators appear to have scribbled down the notes quickly. Many are smudged or illegible. Others depict complex diagrams and are peppered with technical jargon or acronyms such as SBO for "station blackout." http://online.wsj.com/article/SB10001424052748704281504576329011846064194.html

  • So helpless were the plant's engineers that, as dusk fell after Japan's devastating March 11 quake and tsunami, they were forced to scavenge flashlights from nearby homes. They pulled batteries from cars not washed away by the tsunami in a desperate effort to revive reactor gauges that weren't working properly. The plant's complete power loss contributed to a failure of relief vents on a dangerously overheating reactor, forcing workers to open valves by hand.And in a significant miscalculation: At first, engineers weren't aware that the plant's emergency batteries were barely working, the investigation found—giving them a false impression that they had more time to make repairs. As a result, nuclear fuel began melting down hours earlier than previously assumed. This week Tokyo Electric Power Co., or Tepco, confirmed that one of the plant's six reactors suffered a substantial meltdown early in Day 1. http://online.wsj.com/article/SB10001424052748704322804576302553455643510.html
  • Lots of interesting information in this paper from TEPCO:http://www.tepco.co.jp/en/nu/fukushima-np/images/handouts_110525_01-e.pdfUnits 1-4 did not have RCIC.  They had isolation condensers.  Not only that, the isolation condensers were water cooled with 8 hours of water in the condenser reservoir. 
  • HPCI required DC power to operate.  The turbine lube oil pump was DC; it didn't have a shaft oil pump.  I think this may be common here too, anyone willing to verify that?That's why they had trouble so quick:  8 hours later and without AC power they had no way to get water to the pressure vessel.  About the same time the instruments died from a lack of battery power is about the time they lost the isolation condenser from a lack of water.They also verify that they didn't have the hardened vent modification.
  • Fukushima may have a group that could tackle the nuclear crisis looming over Japan. The Skilled Veterans Corps, retired engineers and professionals, want to volunteer to work in the dangerous conditions instead of putting younger generations at risk. More than 200 Japanese retirees are seeking to replace younger workers at Fukushima while the plant is being stabilized. http://www.digitaljournal.com/article/307378

  • The following article focus's on US spent fuel storage safety, Several members of Congress are calling for the fuel to be moved from the pools into dry casks at a faster clip, noting that the casks are thought to be capable of withstanding an earthquake or a plane crash, they have no moving parts and they require no electricity. but there is a reference to Fukishima's dry storage casks farther into the article.But Robert Alvarez, a former senior adviser to the secretary of energy and expert on nuclear power, points out that unlike the fuel pools, dry casks survived the tsunami at Fukushima unscathed. “They don’t get much attention because they didn’t fail,” he said.http://www.nytimes.com/2011/07/06/business/energy-environment/06cask.html?_r=2&pagewanted=1&ref=science
  • In 1967, Tepco chopped 25 meters off the 35-meter natural seawall where the reactors were to be located, according to documents filed at the time with Japanese authorities. That little-noticed action was taken to make it easier to ferry equipment to the site and pump seawater to the reactors. It was also seen as an efficient way to build the complex atop the solid base of bedrock needed to better protect the plant from earthquakes.But the razing of the cliff also placed the reactors five meters below the level of 14- to 15-meter tsunami hitting the plant March 11, triggering a major nuclear disaster resulting in the meltdown of three reactor cores.http://online.wsj.com/article/SB10001424052702303982504576425312941820794.html
  • Toyota was a key executive who was involved in the Fukushima No. 1 plant construction.It is actually common practice to build primary nuclear plant facilities directly on bedrock because of the temblor factor.Toyota also cited two other reasons for Tepco clearing away the bluff — seawater pumps used to provide coolant water needed to be set up on the ground up to 10 meters from the sea, and extremely heavy equipment, including the 500-ton reator pressure vessels, were expected to be brought in by boat.In fact, Tepco decided to build the plant on low ground based on a cost-benefit calculation of the operating costs of the seawater pumps, according to two research papers separately written by senior Tepco engineers in the 1960s.
  • If the seawater pumps were placed on high ground, their operating costs would be accordingly higher."We decided to build the plant at ground level after comparing the ground construction costs and operating costs of the circulation water pumps," wrote Hiroshi Kaburaki, then deputy head of the Tepco's construction office at the Fukushima No. 1 plant, in the January 1969 edition of Hatsuden Suiryoku, a technical magazine on power plants.Still, Tepco believed ground level was "high enough to sufficiently secure safety against tsunami and typhoon waves," wrote Seiji Saeki, then civil engineering section head of Tepco's construction office, in his research paper published in October 1967.
  • Engineers at Tohoku Electric Power Co., on the other hand, had a different take on the tsunami threat when the Onagawa nuclear plant was built in Miyagi Prefecture in the 1980s.Like Fukushima, the plant was built along the Tohoku coast and was hit by tsunami as high as 13 meters on March 11.Before building the plant, Tohoku Electric, examining historic records of tsunami reported in the region, conducted computer simulations and concluded the local coast could face tsumani of up to 9.1 meters.Tohoku Electric had set the construction ground level at 14.8 meters above sea level — which barely spared the Onagawa plant from major damage from 13-meter-high tsunami that hit in March.
  • Former Tepco worker Naganuma said many locals now feel they have been duped by Tepco's long-running propaganda on the safety of its nuclear facilities, despite the huge economic benefits the plant brought to his hometown of Okuma, which hosts the Fukushima No. 1 plant.

Leakage causes operators to shut down Nine Mile 2 nuclear plant [06Aug11] - 0 views

  • Scriba, NY – The Nine Mile Point 2 nuclear station was shut down this morning after higher than normal leakage was detected in its drywell, the plant’s operator said. Constellation Energy Nuclear Group officials declared an “unusual event,” the lowest-level emergency, at 3:22 a.m. and began a controlled shutdown, Constellation officials said in a prepared statement. The leakage rate decreased as the reactor power declined, allowing plant officials to call off the unusual event at 11:27 a.m. Employees this afternoon continued to seek the cause of the leak. The plant will remain shut down so repairs can be made, Constellation officials said. The incident posed no risk to the public or plant employees, officials said.
