Battling for nuclear energy by exposing opposition motives [19Jul11] - 0 views

  • In the money-driven battle over our future energy supply choices, the people who fight nuclear energy have imagination on their side. They can, and often do, invent numerous scary tales about what might happen without the need to actually prove anything.
  • One of the most powerful weapons in their arsenal is the embedded fantasy that a nuclear reactor accident can lead to catastrophic consequences that cannot be accepted. This myth is doubly hard to dislodge because a large fraction of the nuclear energy professionals have been trained to believe it. When you want to train large numbers of slightly above average people to do their job with great care and attention to detail, it can be useful to exaggerate the potential consequences of a failure to perform. It is also a difficult myth to dislodge because the explanation of why it is impossible requires careful and often lengthy explanations of occasionally complex concepts.
  • The bottom lines of both Chernobyl and Fukushima tell me that the very worst that can realistically happen to nuclear fission reactors results in acceptable physical consequences when compared to the risk of insufficient power or the risk of using any other reliable source of power. The most negative consequences of both accidents resulted from the way that government leaders responded, both during the crisis stage and during the subsequent recoveries.

  • Instead of trying to explain the basis for those statements more fully, I’ll try to encourage people to consider the motives of people on various sides of the discussion. I also want to encourage nuclear energy supporters to look beyond the financial implications to the broader implications of a less reliable and dirtier electrical power system. When the focus is just on the finances, the opposition has an advantage – the potential gains from opposing nuclear energy often are concentrated in the hands of extremely interested parties while the costs are distributed widely enough to be less visible. That imbalance often leads to great passion in the opposition and too much apathy among the supporters. Over at Idaho Samizdat, Dan Yurman has written about the epic battle of political titans who are on opposing sides of the controversy regarding the relicensing and continued operation of the Indian Point Nuclear Power Station. Dan pointed out that there is a large sum of money at stake, but he put it in a way that does not sound too terrible to many people because it spreads out the pain.
  • In round numbers, if Indian Point is closed, wholesale electricity prices could rise by 12%.
  • A recent study quoted in a New York Times article put the initial additional cost of electricity without Indian Point at about $1.5 billion per year, which is a substantial sum of money if concentrated into the hands of a few thousand victors who tap the monthly bills of a few million people. Here is a comment that I added to Dan’s post:Dan – thank you for pointing out that the battle is not really a partisan one determined by political party affiliation. By my analysis, the real issue is the desire of natural gas suppliers to sell more gas at ever higher prices driven by a shift in the balance between supply and demand.
  • They never quite explain what is going to happen as we get closer and closer to the day when even fracking will not squeeze any more hydrocarbons out of the drying sponge that is the readily accessible part of the earth’s crust.The often touted “100 – year” supply of natural gas in the US has a lot of optimistic assumptions built in. First of all, it is only rounded up to 100 years – 2170 trillion cubic feet at the end of 2010 divided by 23 trillion cubic feet per year leaves just 94 years.
  • Secondly, the 2170 number provided by the Potential Gas Committee report includes all proven, probable, possible and speculative resources, without any analysis of the cost of extraction or moving them to a market. Many of the basins counted have no current pipelines and many of the basins are not large enough for economic recovery of the investment to build the infrastructure without far higher prices.Finally, all bets are off with regard to longevity if we increase the rate of burning up the precious raw materia
  • BTW – In case your readers are interested in the motives of a group like Riverkeepers, founded and led by Robert F. Kennedy, Jr., here is a link to a video clip of him explaining his support for natural gas.http://atomicinsights.com/2010/11/power-politics-rfk-jr-explains-how-pressure-from-activists-to-enforce-restrictions-on-coal-benefits-natural-gas.html
  • The organized opposition to the intelligent use of nuclear energy has often painted support for the technology as coming from faceless, money-hungry corporations. That caricature of the support purposely ignores the fact that there are large numbers of intelligent, well educated, responsible, and caring people who know a great deal about the technology and believe that it is the best available solution for many intransigent problems. There are efforts underway today, like the Nuclear Literacy Project and Go Nuclear, that are focused on showcasing the admirable people who like nuclear energy and want it to grow rapidly to serve society’s never ended thirst for reliable power at an affordable price with acceptable environmental impact.
  • The exaggerated, fanciful accident scenarios painted by the opposition are challenging to disprove.
  • I just read an excellent post on Yes Vermont Yankee about a coming decision that might help to illuminate the risk to society of continuing to let greedy antinuclear activists and their political friends dominate the discussion. According to Meredith’s post, Entergy must make a decision within just a week or so about whether or not to refuel Vermont Yankee in October. Since the sitting governor is dead set against the plant operating past its current license expiration in the summer of 2012, the $100 million dollar expense of refueling would only result in about 6 months of operation instead of the usual 18 months.Meredith has a novel solution to the dilemma – conserve the fuel currently in the plant by immediately cutting the power output to 25%.

Experts split on how to decommission Fukushima nuclear plant [29Aug11] - 0 views

  • What is actually going to take place at the Fukushima No. 1 Nuclear Power Plant, where word is that the four reactors that were crippled in the Great East Japan Earthquake and tsunami will eventually be decommissioned? The Ministry of Economy, Trade and Industry's Nuclear and Industrial Safety Agency (NISA) defines "decommissioning" as the process of removing spent fuel from reactors and dismantling all facilities. Ultimately, the site of a decommissioned reactor is meant to be reverted into a vacant lot.
  • In 1996, the then Japan Atomic Energy Research Institute (JAERI) -- now the Japan Atomic Energy Agency (JAEA) -- finished decommissioning its Japan Power Demonstration Reactor. The decommissioning process of the Tokai Nuclear Power Plant in the Ibaraki Prefecture village of Tokai began in 1998 and is set to end in fiscal 2020, while the No. 1 and No. 2 nuclear reactors at the Hamaoka Nuclear Power Plant in the Shizuoka Prefecture city of Omaezaki are slated for decommissioning by fiscal 2036. Around the world, only around 15 nuclear reactors have thus far been dismantled.
  • The standard decommissioning process entails six major steps: 1. Remove spent fuel rods, 2. Remove radioactive materials that have become affixed to reactor pipes and containers, 3. Wait for radiation levels to go down with time, 4. Dismantle reactors and other internal vessels and pipes, 5. Dismantle the reactor buildings, and 6. Make the site into a vacant lot.
  • ...17 more annotations...
  • "Cleaning," "waiting," and "dismantling" are the three key actions in this process. Needless to say, this all needs to be done while simultaneously containing radioactive materials.
  • In the case of the Tokai Nuclear Power Plant, the first commercial plant to undergo decommissioning, spent fuel was removed over a span of three years beginning in 1998, and was transported to Britain for reprocessing. Dismantling of the facilities began in 2001, with current efforts being made toward the dismantling of heat exchangers; workers have not yet begun to take the reactor itself apart. The entire process is expected to be an 88.5-billion-yen project involving 563,000 people.
  • Hitachi Ltd., which manufactures nuclear reactors, says that it "generally takes about 30 years" to decommission a reactor. The Hamaoka Nuclear Power Plant's No. 1 and No. 2 reactors operated by Chubu Electric Power Co. are also expected to take about 30 years before they are decommissioned.
  • In the case of the Fukushima No. 1 Nuclear Power Plant, meanwhile, the biggest challenge lies in how to remove the fuel, says Tadashi Inoue, a research advisor at the Central Research Institute of Electric Power Industry (CRIEPI), a foundation that conducts research on energy and environmental issues in relation to the electrical power industry.
  • "we must deal with rubble contaminated with radioactive materials that were scattered in the hydrogen blasts and treat the radiation-tainted water being used to cool nuclear fuel before we can go on to fuel removal."
  • Currently, the Fukushima plant's operator, Tokyo Electric Power Co. (TEPCO), is desperately trying to treat the contaminated water. Huge challenges remain with regards to the contaminated rubble, as radiation levels of over 10 sieverts per hour were found near outdoor pipes on the plant grounds just the other day. Exposure to such high levels would mean death for most people.
  • Each step in the process toward decommissioning is complicated and requires great numbers of people. It's a race against time because the maximum amount of radiation that workers can be exposed to is 250 millisieverts.
  • Prefacing the following as "a personal opinion," Inoue says: "Building a car that can protect the people inside as much as possible from radioactive materials, and attaching an industrial robotic arm to the car that can be manipulated by those people could be one way to go about it."
  • Two types of fuel removal must take place. One is to take out the spent fuel in the containment pools, and the other is to remove the melted fuel from the reactor cores. Because the radiation levels of the water in the spent fuel pools have not shown any significant changes from before the crisis, it is believed that the spent fuel has not suffered much damage. However, removing it will require repairing and reinstalling cranes to hoist the fuel rods out.
  • The breached reactor core is a bigger problem. It is believed that raising water levels inside the reactor has been difficult because of a hole in the bottom of the vessel. It will be necessary to plug the hole, and continue filling the vessel with water while extracting the melted fuel. How to fill the vessel with water is still being debated. If the reactor can be filled with water, steps taken after the 1979 Three Mile Island nuclear accident can serve as a guide because in that case, in which approximately 50 percent of the core had melted, workers were able to fill the reactor with water and remove the fuel within.
  • Inoue predicts that removal of spent fuel from the containment pools will begin about five years after the crisis, and about 10 years in the case of melted fuel from the reactor core. Work on the four reactors at the Fukushima plant will probably take several years.
  • "Unless we look at the actual reactors and take and analyze fuel samples, we can't know for sure," Inoue adds. Plus, even if workers succeed in removing the fuel, reprocessing it is an even more difficult task. A review of processing methods and storage sites, moreover, has yet to take place.
  • Meanwhile, at least one expert says he doesn't believe that workers will be able to remove the melted fuel from the crippled plant.
  • "If there's 10 sieverts per hour of radiation outside, then the levels must be much higher closer to the reactor core," says Tadahiro Katsuta, an associate professor at Meiji University and an expert in reactor engineering and reactor policy who was once a member of an anti-nuclear non-profit organization called Citizens' Nuclear Information Center (CNIC). "The fuel has melted, and we haven't been able to cool it consistently. If work is begun five or 10 years from now when radiation levels have not yet sufficiently gone down, workers' health could be at serious risk."
  • Katsuta predicts that it will probably take at least 10 years just to determine whether it is possible to remove the fuel. He adds that it could very well take 50 years before the task of dismantling the reactor and other facilities is completed.
  • What Katsuta has in mind is a Chernobyl-style concrete sarcophagus, which would entail cloaking the melted tomb with massive amounts of concrete. "How could we simultaneously dismantle four reactors that have been contaminated to the extent that they have by radioactive materials?" asks Katsuta. "Japan has little experience in decommissioning reactors, and this case is quite different from standard decommissioning processes. It's not realistic to think we can revert the site back to a vacant lot. I think we should be considering options such as entombing the site with concrete or setting up a protective dome over the damaged reactor buildings
  • what we face is a great unknown to all of mankind.

The Rally for Vermont Yankee: At the Plant Gates During the Refueling Outage [26Oct11] - 0 views

  • The Vermont Yankee nuclear power plant is undergoing a refueling outage. For most plants, the situation would be business as usual.  The state of Vermont, however, believes it has the power to shut down Vermont Yankee in March 2012, even though the plant has a 20-year license extension from the U.S. Nuclear Regulatory Commission. In order to continue operations at Vermont Yankee, Entergy (the plant’s owner and operator) has sued the state. In these uncertain circumstances, it was unclear whether or not Vermont Yankee would buy and load fuel in October. A decision to load fuel would mean that Entergy might lose tens of millions of dollars if the plant is actually shut down in March. Entergy’s other choice was closing the plant in October, which would mean job losses, rising electricity prices, and increased air pollution in Vermont.
  • The company made a choice to keep the plant running, even amidst uncertainty. Entergy is loading fuel right now at Vermont Yankee, which is a true vote of confidence in nuclear power! Motivation for the Rally We decided to show our support for Entergy’s decision and for all the workers at the refueling. Howard Shaffer and I planned a pro-nuclear rally that would take place right at the gates of the plant during shift change. We wanted the workers to see that people support them! Here’s a quote from the press release about the rally:
  • “The people working the outage will appreciate our support,” said co-organizer Howard Shaffer, coordinator of the Vermont Pilot Project of the American Nuclear Society. “We are grateful to Entergy for giving us permission to be at the Governor Hunt House for the rally.”
  • ...4 more annotations...
  • Howard and I planned thoroughly, as usual. We sent a press release. We sent e-mails to lists of people, inviting them to come. I put the rally on my blog and on the Save Vermont Yankee Facebook page. Howard sent a practical e-mail with directions to the plant and recommendations for dressing for the weather. He stressed the importance of wearing sturdy-soled shoes for standing on damp grass. We did everything we could to make the rally a success. We had held a rally before, early in the morning of the first day of the Entergy/Vermont trial. At that rally, we had 25 people, a good showing, and reporters noted that both opponents and supporters of the plant were present. (I blogged about this rally at ANS Nuclear Cafe). We hoped to have an equally successful rally this time.
  • Instead, this rally  “went viral.” About 25 people had said they would come. Instead, there were about 60 people! People told their friends. People brought their kids. One man of 92 years came to support the plant.  (He is sitting on the bench in the photo.) One couple came down from Vermont’s Champlain Islands. A man who owns the local tavern came with his son. Among all these people, I met some who I had previously met only on Facebook, and I met their kids, too! Two documentary filmmakers interviewed Howard, and one interviewed me. The people at the plant were very happy, honking, and waving at us. “Nuke Roadie” (look up his Facebook page) was there and posted pictures of the rally on his page. The plant posted great pictures of the rally on the Vermont Yankee Facebook page.  (I include some of those pictures here, by permission.)
  • An article that appeared in the Brattleboro Reformer newspaper was very positive about the event.  Since the supporters came and went during the rally, however, the article stated there were thirty people. Actually, there were about twice that many. Lessons Learned What are some of the lessons learned from this rally? Well, the rally was yesterday, and we haven’t quite digested all the lessons yet, but here are some:
  • Organizations grow. Success at one rally helps build success at the next one. People tell their friends. Afternoon rallies are better than rallies that start at 7:30 a.m., at least in terms of getting people to show up. (Yeah, this is obvious…) Some rallies let people stand up for nuclear in a potentially confrontational situation (our first rally). On the other hand, sometimes it’s great just to be among friends! This pro-nuclear rally was a great evening amongst friends!

Uranium Mining is Poisoning the Bread Basket of the World - 0 views

  •  
    Thousands of open uranium mines excavated beginning in the 1950s continues to release radiation today. There have been inadequate measurements but the limited measures done show ongoing leaks larger than Fukushima. How did we get here? It is estimated that 60 to 80 percent of uranium in the US is located on tribal land, particularly in the lands of the Navajo and Great Sioux Nations.

Japan-based Author: Fukushima damage so great "Japan gov't would go well beyond bankruptcy" - Up to $10 trillion says Tokyo prof. - Equal to 10 years of national budget [09Nov11] - 0 views

  • Writer urges Taiwan to abandon nuclear power, Taipei Times, Nov. 9, 2011: Saying that the compensation for damage caused by the nuclear crisis at the Fukushima Dai-ichi nuclear power plant in Japan was way beyond what Tokyo Electric Power Co (TEPCO) or the Japanese government could afford, a Japan-based Taiwanese writer yesterday urged Taiwan to abandon all nuclear power. Writer Liu Li-erh (劉黎兒), who has lived in Tokyo for 30 years, made the appeal at a press conference held at the legislature [...]
  • Liu said the president of TEPCO had remarked that nuclear power was actually a very expensive power source when compensation fees are calculated, and that a professor from the University of Tokyo has even estimated that it would cost up to ¥800 trillion, amounting to approximately 10 years of the national budget, if the soil and road surface of radiation-affected areas are to be cleaned up. The damage is so much that the Japanese government would go well beyond bankruptcy, Liu said.

NUCLEAR POWER - Resisting "Rust Belt" reactors' radioactive risks! [04Aug12] - 0 views

  • As if the closing steel mills and automobile manufacturing plants weren't bad enough, some of the oldest, most risky atomic reactors in the U.S. are located in the Midwest. Worse still, they are on the shores of the Great Lakes, putting at risk the drinking water supply for 40 million people downstream in the U.S., Canada, and a large number of Native American First Nations. Altogether, 33 atomic reactors are located on the shorelines of the Great Lakes. Two of the most infamous of these radiologically risky "Rust Belt reactors" are Entergy Nuclear's Palisades in southwest Michigan, and FirstEnergy's Davis-Besse in northwest Ohio.
  • Last month, U.S. Rep. Ed Markey (D-MA), a long-time watchdog on the nuclear industry, wrote the U.S. Nuclear Regulatory Commission (NRC) about an acidic, radioactive leak representing a "crisis in the control room at the Palisades nuclear power plant." The leakage had been ongoing for a year, and was being "contained" in glorified buckets referred to by Entergy PR spokesman Mark Savage as "catch basins." Although the leak came to light when Palisades was forced to shutdown after its rate reached more than 30 gallons per day, it had been ongoing for months at a rate of 15 gallons per day. The tritiated and borated water is leaking from a 300,000 gallon Safety Injection Refueling Water storage tank, which is safety critical for both reactor core and radiological containment cooling. Whistleblowers contacted Washington, D.C. attorney Billie Pirner Garde, who alerted Rep. Markey, who wrote NRC. The NRC Office of Investigations has launched a probe into potential Entergy wrongdoing. On July 17th, NRC issued a "Confirmatory Action Letter" which enables Palisades to keep operating into 2013, even if the leak increases to nearly 38 gallons per day!
  • Markey demanded a copy of an internal Entergy report surveying its own workers on "safety culture" at Palisades. Michigan Radio obtained a copy, which reveals "a lack of accountability at all levels," and a workforce deeply distrustful of management, fearful that they will be harassed and punished if they dare to raise safety concerns.

WNA Director: Nuclear Reborn? [11Mar10] - 0 views

  • In Europe and the United States, signs of the long-discussed “nuclear renaissance” are increasingly positive. But it’s in China (which now has 21 out of the 53 reactors under construction around the world) that the initial boom is occurring. Increasing mentions of nuclear power in the mass media, often with a generally positive slant, are very welcome, but the industry now needs to build new reactors in great volume. China, with its vast requirements for clean power generation, is therefore the key
  • An important element has been public statements from respected third-party advocates for nuclear, many of whom were previously either strongly opposed or seen as agnostic. Some of these come from the environmental movement, notably Patrick Moore, one of the founders of Greenpeace, but the support of James Lovelock, the originator of the Gaia Theory of the Earth as a self-regulating organism, has been particularly important.
  • The industry has recognised that securing public buy-in is critical and conditional upon in-depth dialogue. It accepts that concerns over safety, waste and non-proliferation will continue to impose a strict regulatory regime on the industry and that this is necessary, despite it costing a great deal of valuable time and money. 
  • ...2 more annotations...
  • One possible barrier to renewed industry growth is the 20-year mummification of the industry’s supply sector. However, this is changing, with membership of the UK Nuclear Industry Association (NIA) booming as companies realise that there will be many new opportunities in this sector as the UK returns to building reactors. Another possible negative, namely the need to ensure a strict world non-proliferation regime, has been reinforced by the North Korean and Iranian cases, to which endless column inches and analyses have been devoted.  On the other hand, three highly important factors have moved very strongly in the industry’s favour: the industry’s own operating performance, the greenhouse gas emissions debate and concerns over energy security of supply
  • The 435 reactors around the world generate electricity very cheaply and earns significant profits for their owners, irrespective of the power market, whether it is liberalised or regulated. The challenge for the industry is to cut the capital investment costs of new reactors to enable many new reactor projects to go forward. Concerns over climate change and the perceived need to moderate greenhouse gas emissions has worked strongly in the industry’s favour and, at the very least, have opened an opportunity for the industry as a viable mitigation technology. The argument for more nuclear power as a means of securing additional energy security of supply has also become increasingly important, particularly in those countries who perceive themselves as becoming increasingly reliant on supplies from geopolitically unstable or otherwise unattractive countries. It is important to recall that this was the main argument that prompted both France and Japan, now numbers two and three in world nuclear generation, to go down this path in the 1970s in the aftermath of two “oil shocks”.

Senator Lamar Alexander: "Nuclear Power Is the Most Reliable and Useful Source of Green Electricity Today" [16JUN10] - 0 views

  • U.S. Senator Lamar Alexander (R-Tenn.), chairman of the Senate Republican Conference, delivered a speech this week at the International V.M. Goldschmidt Conference in Knoxville.  Alexander serves on the Senate Environment and Public Works Committee and is the chairman of the Tennessee Valley Authority Congressional Caucus.  His remarks as prepared follow:
  • When
  • in a speech in Oak Ridge in May of 2009, I called for America to build 100 new nuclear plants during the next twenty years.  Nuclear power produces 70 percent of our pollution-free, carbon-free electricity today.  It is the most useful and reliable source of green electricity today because of its tremendous energy density and the small amount of waste that it produces.  And because we are harnessing the heat and energy of the earth itself through the power of the atom, nuclear power is also natural.
  • ...10 more annotations...
  • Forty years ago, nuclear energy was actually regarded as something of a savior for our environmental dilemmas because it didn’t pollute.  And this was well before we were even thinking about global warming or climate change.  It also didn’t take up a great deal of space.  You didn’t have to drown all of Glen Canyon to produce 1,000 megawatts of electricity.  Four reactors would equal a row of wind turbines, each one three times as tall as Neyland Stadium skyboxes, strung along the entire length of the 2,178-mile Appalachian Trail.   One reactor would produce the same amount of electricity that can be produced by continuously foresting an area one-and-a-half times the size of the great Smoky Mountains National Park in order to create biomass.  Producing electricity with a relatively small number of new reactors, many at the same sites where reactors are already located, would avoid the need to build thousands and thousands of miles of new transmission lines through scenic areas and suburban backyards. 
  • While nuclear lost its green credentials with environmentalists somewhere along the way, some are re-thinking nuclear energy because of our new environmental paradigm – global climate change.  Nuclear power produces 70 percent of our carbon-free electricity today.  President Obama has endorsed it, proposing an expansion of the loan guarantee program from $18 billion to $54 billion and making the first award to the Vogtle Plant in Georgia.  Nobel Prize-winning Secretary of Energy Steven Chu wrote recently in The Wall Street Journal about developing a generation of mini-reactors that I believe we can use to repower coal boilers, or more locally, to power the Department of Energy’s site over in Oak Ridge.  The president, his secretary of energy, and many environmentalists may be embracing nuclear because of the potential climate change benefits, but they are now also remembering the other positive benefits of nuclear power that made it an environmental savior some 40 years ago
  • The Nature Conservancy took note of nuclear power’s tremendous energy density last August when it put out a paper on “Energy Sprawl.”  The authors compared the amount of space you need to produce energy from different technologies – something no one had ever done before – and what they came up with was remarkable.  Nuclear turns out to be the gold standard.  You can produce a million megawatts of electricity a year from a nuclear reactor sitting on one square mile.  That’s enough electricity to power 90,000 homes.  They even included uranium mining and the 230 square miles surrounding Yucca Mountain in this calculation and it still comes to only one square mile per million megawatt hours
  • And for all that, each turbine has the capacity to produce about one-and-a-half megawatts.  You need three thousand of these 50-story structures to equal the output of one nuclear reactor
  • When people say “we want to get our energy from wind,” they tend to think of a nice windmill or two on the horizon, waving gently – maybe I’ll put one in my back yard.   They don’t realize those nice, friendly windmills are now 50 stories high and have blades the length of football fields.  We see awful pictures today of birds killed by the Gulf oil spill.  But one wind farm in California killed 79 golden eagles in one year. The American Bird Conservancy says existing turbines can kill up to 275,000 birds a year.
  • Coal-fired electricity needs four square miles, because you have to consider all the land required for mining and extraction.  Solar thermal, where they use the big mirrors to heat a fluid, takes six square miles.  Natural gas takes eight square miles and petroleum takes 18 square miles – once again, including all the land needed for drilling and refining and storing and sending it through pipelines.  Solar photovoltaic cells that turn sunlight directly into electricity take 15 square miles and wind is even more dilute, taking 30 square miles to produce that same amount of electricity.
  • , wind power can be counted on to be there 10 to 15 percent of the time when you need it.  TVA can count on nuclear power 91 percent of the time, coal, 60 percent of the time and natural gas about 50 percent of the time.  This is why I believe it is a taxpayer rip-off for wind power to be subsidized per unit of electricity at a rate of 25 times the subsidy for all other forms of electricity combined. 
  • the “problem of nuclear waste” has been overstated because people just don’t understand the scale or the risk.  All the high-level nuclear waste that has ever been produced in this country would fit on a football field to a height of ten feet.  That’s everything.  Compare that to the billion gallons of coal ash that slid out of the coal ash impoundment at the Kingston plant and into the Emory River a year and a half ago, just west of here.  Or try the industrial wastes that would be produced if we try to build thousands of square miles of solar collectors or 50-story windmills.  All technologies produce some kind of waste.  What’s unique about nuclear power is that there’s so little of it.
  • Now this waste is highly radioactive, there’s no doubt about that.  But once again, we have to keep things in perspective.  It’s perfectly acceptable to isolate radioactive waste through storage.  Three feet of water blocks all radiation.  So does a couple of inches of lead and stainless steel or a foot of concrete.  That’s why we use dry cask storage, where you can load five years’ worth of fuel rods into a single container and store them right on site.  The Nuclear Regulatory Commission and Energy Secretary Steven Chu both say we can store spent fuel on site for 60 or 80 years before we have to worry about a permanent repository like Yucca Mountain
  • then there’s reprocessing.  Remember, we’re now the only major nuclear power nation in the world that is not reprocessing its fuel.  While we gave up reprocessing in the 1970s, the French have all their high-level waste from 30 years of producing 80 percent of their electricity stored beneath the floor of one room at their recycling center in La Hague.  That’s right; it all fits into one room.  And we don’t have to copy the French.  Just a few miles away at the Oak Ridge National Laboratory they’re working to develop advanced reprocessing technologies that go well beyond what the French are doing, to produce a waste that’s both smaller in volume and with a shorter radioactive life.  Regardless of what technology we ultimately choose, the amount of material will be astonishingly small.  And it’s because of the amazing density of nuclear technology – something we can’t even approach with any other form of energy

IAEA To Host Conference On Nuclear Power HR Development [31Dec09] - 0 views

  •  
    This won't highlight, here is an intro clip: "More than 50 Member States have recently approached the IAEA expressing interest in launching a nuclear power programme. In all cases the development of human resources capable of supporting the implementation of these programmes has been identified as one of the main challenges. Additionally, many of the 30 Member States that already have nuclear power programmes are either expanding, or considering the expansion of their programmes. For many of them this comes at the same time as there is a need to replace the generation of workers that commissioned the plants now in operation. Given these needs, the education, recruitment, selection, training, qualification and retention of human resources to support the introduction and expansion of nuclear power programmes has been a matter of concern for many national governments and has attracted a great deal of attention and support from industry and international organizations. The decline in the number of younger people studying nuclear sciences and a growing number of universities giving up or strongly limiting their nuclear education programmes have given rise to new initiatives for networking educational institutions, universities and industry training centres. New national and international "platforms" for sharing knowledge and expertise in nuclear education and training (WNU, ANENT, ENEN, ANSN, UNENE and others) have been established and have become the drivers renewed interest in nuclear education"

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.

Inside Fukushima's nuclear ghost town abandoned by people fleeing the fallout |[04Sep11] - 0 views

  • Haunting images taken in a town close to Japan's stricken Fukushima nuclear plant have been released showing a community frozen in time.The new set of photographs, taken in the town of Futaba 12 miles from the Fukushima plant, bear grim similarities to those taken in Pripyat, two miles from the Chernobyl power plant.Children's play areas lie deserted, lonely dogs wander through empty streets, shoes and personal keepsakes are left hastily abandoned in the two towns, both the scenes of hasty evacuations after explosions at the nearby nuclear power stations.

Opinion: Small modular nuclear reactors should power U.S. energy strategy [16Oct11] - 0 views

  • Sen. Dianne Feinstein (D-Calif.) was on her high horse, and the California Democrat wasn’t going to pass up an opportunity to disparage nuclear power. As head of a Senate panel that controls spending on energy technology, Sen. Feinstein zeroed in on a new program that would design small modular reactors over the next five years, striking it from the Department of Energy (DOE) budget for the coming fiscal year. Yet it happens to be precisely the sort of “Made in America” program with great commercial potential that President Obama called for in his jobs speech.
  • Feinstein prefers renewable energy sources, favoring government financial support for solar energy. Never mind that Solyndra Inc., a California-based maker of solar panels that received a $535 million U.S. loan guarantee, recently went bankrupt, along with two other solar firms. By contrast, small modular reactors are affordable and practical. They could be built in U.S. factories for a fraction of the cost of a large nuclear plant and exported for use in generating electricity around the world. In fact, small reactors have been used successfully for more than a half-century to power the U.S. Navy’s nuclear submarines. And the U.S. Army used small reactors during the 1950s and 1960s to provide electricity at remote military installations in Wyoming, Alaska, Greenland, Antarctica and other locations.
  • Several other countries with nuclear programs see great commercial potential in modular reactors; France, China, Japan and Korea are developing simplified, cheaper designs for a global market. “Our choice is clear: Develop these technologies today or import them tomorrow,” Energy Secretary Steven Chu said recently.

  • To jump-start construction of modular reactors, the administration proposed a cost-sharing program of $500 million over five years to help two companies develop designs and obtain Nuclear Regulatory Commission licenses. The DOE funds would be equally matched with industry money. There are those who maintain the government should not be involved in energy development, and that it should be left to the marketplace to determine which technologies emerge in America’s energy future. That’s an understandable sentiment, given the Solyndra scandal. But nuclear power, which has enabled the nation to meet its energy needs for more than a half-century without polluting the air or depending on the whims of foreign rulers, got its start with government financial backing. The first nuclear plants were built with government funds.
  • Like conventional nuclear plants, small modular reactors could produce electricity around the clock, day in and day out, without being subject to weather conditions. But what’s especially appealing about small reactors is their affordability. Instead of having to pay the capital cost of a new nuclear plant, which can run $8 billion or more, a utility would have the option of ordering small modular reactors for construction in a series, as funds become available and the need for electricity arises. The Tennessee Valley Authority recently signed a letter of intent to buy six small modular reactors using conventional light–water reactor technology, each with the capacity to produce 125 megawatts of electricity, from Babcock & Wilcox, a Virginia-based nuclear manufacturer. A small reactor is expected to take three years to build instead of five years or more for a conventional 1,200-megawatt nuclear plant. Experts say that a prototype reactor would cost about $500 million.
  • Small modular reactors — known as SMRs — would be shipped from a factory by rail or truck to a nuclear site and situated side-by-side. They would be hooked to the same electric-power grid but operate independently of one another. One module could be taken off line for refueling and maintenance while the others produce electricity. At some locations, modular reactors could be situated beneath the ground for security. What’s more, SMRs are air-cooled. They don’t have to be located on the oceanfront or near lakes and rivers, an important feature in large parts of the world where water resources are scarce.
  • The question is whether, in the face of opposition from Sen. Feinstein and some other members, Congress will make funds available for developing SMRs. At least 10 U.S. nuclear companies have done preliminary design work. They include such well-known names as Westinghouse, General Electric, General Atomics and Babcock & Wilcox. And a number of start-up companies are part of the competition. “SMRs could change the game and restore U.S. leadership in nuclear power,” said Vic Reis, a senior adviser in the Department of Energy’s Office of Science. “Nuclear power is essential to the administration’s commitment to clean energy.”
  • But if our reactor designs are going to be competitive in the global marketplace, it is essential that American companies be able to compete on a level playing field. Foreign reactor manufacturers have the backing of their governments in the form of subsidies and grants. Our companies, on the other hand, are cut off from government support. Congress can and must make this a turnaround decade in building a more affordable modular reactor for electricity generation. A factory-built small reactor should be the cornerstone of our government’s energy strategy.

Post-Fukushima, 'they' can no longer be trusted - if ever they could [23Oct11] - 0 views

  • His latest book, "Fukushima Meltdown: The World's First Earthquake-Tsunami-Nuclear Disaster," has just become available online as a Kindle book in an excellent and fluid translation by a team under the guidance of American author and scholar, Douglas Lummis. Originally published as "Fukushima Genpatsu Merutodaun" by Asahi Shinsho on May 30, 2011, this is the book that Hirose had hoped he would never have to write. For three decades he has been warning Japanese people about the catastrophes that could been visited on their country — and now his worst nightmare has become a reality. "This is called the '3/11 Disaster' by many," he writes, "but it did not happen on 3/11, it began on 3/11 and it is continuing today. ... Nuclear power plants are a wildly dangerous way to get electricity and are unnecessary. The world needs to learn quickly from Japan's tragedy." Hirose points out that from day one of the disaster the situation in Fukushima had reached the highest level of nuclear accidents, namely level 7 — and from the outset, the government was keenly aware of this fact. But it chose to conceal the truth from the people.
  • "In past nuclear-plant disasters — those at Chernobyl (in present-day Ukraine, in 1986) and at Three Mile Island (in Pennsylvania in the United States, in 1979) — only one reactor was involved in each. However, at the Fukushima No. 1 plant, four reactors went critical at the same time." On March 13, two days after the tsunami that followed the magnitude-9 Great East Japan Earthquake, Masataka Shimizu, the president of Tokyo Electric Power Co. (Tepco), the operator of the stricken nuclear plant, said at a press conference: "The tsunami was beyond all previous imagination. In the sense that we took all measures that could be thought of for dealing with a tsunami, there was nothing wrong with our preparations." As Hirose and many other commentators have pointed out, Tepco executives and government planners knew perfectly well that tsunamis far exceeding 20 meters in height struck that very region in 1896 and again, 37 years later, in 1933. The 14-meter-high tsunami that inundated many of the Fukushima No. 1 plant's facilities was, in fact, well within the parameters of what could objectively be termed "expected" — and was simply not "beyond all previous imagination," as Shimizu claimed.
  • In fact, the willful absence of care by both industry and government comprises nothing less than a blatant act of savagery against the people of Japan. This book is full of enlightening technical explanations on every aspect of nuclear safety, from structural safeguards (and their clear inadequacy) to the nature of hydrogen explosions and meltdowns. Hirose warns us, with detailed descriptions of the lay of the land and the features of each reactor, about the nuclear power plants at Tomari in Hokkaido, Higashidori in Aomori Prefecture and Onagawa in Miyagi Prefecture; about other plants in Ibaraki, Ishikawa, Shimane, Ehime, Saga and Kagoshima prefectures; and perhaps most dangerous of all, about the 14 reactors along the Wakasa Coast in Fukui Prefecture, constituting what I would call Hōshanō Yokochō (Radioactivity Alley). Many of the reactors at these plants are aging and plagued with serious structural problems.

  • "I have looked through the 'Nuclear Plant Archipelago' from north to south," writes Hirose. "I cannot suppress my amazement that on such narrow islands, laced with active earthquake faults, and with earthquakes and volcanoes coming one after another, so many nuclear power plants have been built." There is no shortage of electricity-generating potential in this country. The 10 regional electric power monopolies have perpetrated the myth of the inevitability of nuclear power in order to manipulate this essential market to their own gain. Tepco created a fear of blackouts this past summer in order to aggrandize its own "sacrificial" role. As Hirose points out, Japan is not a preindustrial country; blackouts are not an issue. Many major companies could independently produce sufficient electricity to cover all of Japan's industrial and domestic needs. They are prevented from doing so by the monopolies created by self-interested businessmen and bureaucrats, and by their many lobbyists occupying seats in the Diet.
  • Hirose states: "Electrical generation and electrical transmission should be separated, and the state should manage the transmission systems in the public interest. ... The great fear is that there are many nuclear power plants in the Japanese archipelago that could become the second or third Fukushima. These nuclear plants could cause catastrophes exceeding the Fukushima disaster and thus affect the whole country and possibly the world." There is little difference between this situation and the one in the 1930s, when all-powerful business conglomerates and complying politicians "convinced" the Japanese people that it was in their interests to go to war. One thing comes out of all of this with crystal clarity: "They" can no longer be trusted — if ever they could.
