German Village; 100% Energy Independent & Renewable [24Aug12] - 0 views

  • The village of Feldheim 60km from Berlin has become an unusual tourist attraction. The village’s independent energy grid and 100% renewable energy sources has gained international attention. The village has its own energy grid and generates power from wind, biogas and solar. The model of Feldheim extinguishes the myth of needing nuclear or fossil fuel for baseload power and the assumption that big utility companies are required for electricity.
  • The transformation in Feldheim began in 1995 with a few wind turbines. Now the village has more wind turbines than homes. in 2008 the village added a biogas heat plant that runs off of corn waste and pig manure with a back up furnace that runs on lumber waste. In 2008 Feldheim decided they wanted their own energy grid. E,on refused to sell the existing grid to the city so they partnered with Energiequelle and built their own smart grid. Each villager paid in $3,972 for the grid installation but get a 31% savings on electricity and 10% savings on heat. It also created 30 permanent jobs for the town. Energiequelle is not building an electricity storage facility that will hold two days worth of electricity.
  • Feldheim did all of this while fighting the big utility companies and Germanies regulatory system that was not friendly to the drastic change Feldheim made.

Drinking the Radioactive Kool-Aid: Countries Switching From Coal to Nuclear [02Dec11] - 0 views

  • South Africa, the host of U.N. global climate talks, is faced with a conundrum -- it wants to wean itself off of coal-powered plants seen as primate culprits of greenhouse gas emissions and find a cleaner energy source.It is turning to nuclear power, despite the catastrophic environmental degradation the world witnessed after Japan's Fukushima plant disaster this year.
  • The global climate talks that opened earlier this week in Durban are seeing a widening division on nuclear power, with many advanced economies moving away from it after Fukushima and emerging states heavily reliant on fossil fuels embracing it as a cleaner way to power their development. "If you want to be part of the climate change race and mitigation you basically have renewables and nuclear. Renewables are intermittent and you need a firm and reliable baseload technology. Renewables are not in a position to provide this yet," said H. Holger Rogner, section head of the International Atomic Energy Agency's planning and economic studies section. South Africa, among the world's top 20 emitters per capita of carbon dioxide, and many other emerging countries, see nuclear power as a way to ensure energy security for the coming years and as a bridge to a time when they are rich enough to afford adding more renewables to their power mix.
  • The Fukushima disaster changed the economics of the nuclear industry by drying up markets in developed countries such as Japan and increasing competition among the few global conglomerates who can build nuclear power plants.

: Iran to Punish EU with Oil Cut for Several Years 29Jan12] - 0 views

  • A senior Iranian lawmaker stressed that Tehran will block its oil supplies to the European Union for the next 5 to 15 years as part of its strategy to punish the EU for its oil ban against Tehran.
  • "We will change the threat into an opportunity for Iran and cut Iran's oil supplies to the Europeans for five to 15 years," member of the parliament's National Security and Foreign Policy Commission Mohammad Karim Abedi told FNA on Sunday.
  • He pointed to a bill drafted in the parliament to cut oil exports to the EU, and noted, "We will not leave enemies' sanctions unanswered and we will impose other sanctions on them in addition to closing Iran's oil supplies to Europe." Abedi also said that Iran will use the banned oil in its refineries and petrochemical complexes to turn it into more valuable products.

Iran postpones vote on banning oil sales to EU [28Jan12] - 0 views

  • An Iranian lawmaker says his parliament has postponed vote on a bill requiring the government to immediately halt crude oil sales to Europe. The ban would be a response to the EU's decision to stop importing Iranian oil and freeze assets of its central bank.
  • Lawmaker Ali Adiani Rad is quoted by the semiofficial ISNA news agency as saying lawmakers need experts' views before they vote on the ban. Many Iranian officials have called for an immediate ban on oil exports to the European bloc before the EU's ban goes into full effect in July.

BP to end cleanup operations in Gulf oil spill [09Nov11] - 0 views

  • Focus will turn to restoring areas damaged in the oil spill, which the coast guard says represents an important milestone
  • BP will officially be off the hook for any deposits of oil that wash up on the shores of the Gulf of Mexico – unless they can be traced directly to the Macondo well, it has emerged.Under a plan approved by the Coast Guard on 2 November, the oil company will end active cleanup operations and focus on restoring the areas damaged by last year's oil disaster.The plan, which was obtained by the Associated Press, sets out a protocol for determining which areas of the Gulf still need to be cleaned, and when BP's responsibility for that would end.
  • The plan "provides the mechanisms for ceasing active cleanup operations", AP said.It went on to suggest the biggest effort would be reserved for the most popular, heavily visited beaches. More oil would be tolerated on remote beaches. BP will be responsible for cleaning up thick oil in marshes – unless officials decide it is best to let nature do its work.The agency quoted coast guard officials saying the plan represented an important milestone in restoring the Gulf. BP has set aside about $1bn for restoration.The Obama administration has been indicating for some time that the Gulf of Mexico oil disaster, which began on 20 April 2010 with an explosion on board the Deepwater Horizon drilling rig that killed 11 workers, was moving into a second phase.Earlier on Tuesday, the US government rolled out a new five-year plan for selling offshore drilling leases.The proposal was a radically scaled back version of the president's earlier plans for offshore drilling – put forward just a few weeks before the Deepwater Horizon blowout – that would have opened up the Arctic and Atlantic coasts for drilling.

  • Oil companies will still be able to apply for leases in the eastern Gulf of Mexico and in two unexplored areas off the northern coast of Alaska.But the government has placed the Atlantic and Pacific coasts off-limits."It will have an emphasis in the Gulf of Mexico," the interior secretary, Ken Salazar, told a meeting. "We see robust oil and gas development in the Gulf of Mexico."A number of commentators described the plan as an attempt to please two implacable enemies: the oil industry and the environmental movement.But the proposals drew heavy criticism from both sides. Oil companies said the plan did not go far enough while environmental groups were angry that Obama was opening up pristine Arctic waters to drilling.

Irreversible Climate Change Looms Within Five Years [09Nov11] - 0 views

  • LONDON, UK, November 9, 2011 (ENS) - Unless there is a "bold change of policy direction," the world will lock itself into an insecure, inefficient and high-carbon energy system, the International Energy Agency warned at the launch of its 2011 World Energy Outlook today in London. The report says there is still time to act, but despite steps in the right direction the door of opportunity is closing
  • The agency's warning comes at a critical time in international climate change negotiations, as governments prepare for the annual UN climate summit in Durban, South Africa, from November 28.
  • international agreement whose effect is put in place by 2017, then the door will be closed forever," IEA Chief Economist Fatih Birol warned today. "Growth, prosperity and rising population will inevitably push up energy needs over the coming decades. But we cannot continue to rely on insecure and environmentally unsustainable uses of energy," said IEA Executive Director Maria van der Hoeven. "Governments need to introduce stronger measures to drive investment in efficient and low-carbon technologies," she said.

  • "The Fukushima nuclear accident, the turmoil in parts of the Middle East and North Africa and a sharp rebound in energy demand in 2010 which pushed CO2 emissions to a record high, highlight the urgency and the scale of the challenge," van der Hoeven said.
  • Some key trends are pointing in worrying directions, the agency told reporters today. CO2 emissions have rebounded to a record high, the energy efficiency of global economy worsened for second straight year and spending on oil imports is near record highs.
  • World Energy Outlook's central New Policies Scenario, which assumes that recent government commitments are implemented in a cautious manner, primary energy demand increases by one-third between 2010 and 2035, with 90 percent of the growth in non-OECD economies. In the New Policies Scenario, cumulative carbon dioxide emissions over the next 25 years amount to three-quarters of the total from the past 110 years, leading to a long-term average temperature rise of 3.5 degrees C. "Were the new policies not implemented, we are on an even more dangerous track, to an increase of six degrees C. The IEA projects that China will consolidate its position as the world's largest energy consumer. It consumes nearly 70 percent more energy than the United States by 2035, even though, by then, per capita demand in China is still less than half the level in the United States. The share of fossil fuels in global primary energy consumption falls from around 81 percent today to 75 percent in 2035.

Louisiana sinkhole, bubbles, 1000s quakes link to oil, gas ENMOD - National Human Right... - 0 views

  • On Monday, as officials warned an explosion is possible from gas in Louisiana’s sinkhole area where radioactive waste has been pumped into a cavern and the Department of Natural Resources (DNR) authorized drilling a new well in the danger sinkhole zone, a seismologist told the Examiner that seismic activity exists in that zone and that fossil fuel industries’ environmental modifications (ENMODs) causing the gas bubbles, giant sinkhole and thousands of quakes resulting in the State of Emergency, is a “real possibility.”
  • Seismic activity is being detected from Louisiana’s giant sinkhole area, according to Horton, whose work at University of Memphis involves monitoring the New Madrid fault line for the United States Geological Survey (USGS) as well as the Louisiana disaster.

South Korea's 15 Year Power Demand Forecast Includes More Nuclear Power Plants [08Dec10] - 0 views

  • South Korea, which currently has 20 operational nuclear reactors, will build 14 new facilities to make atomic power the biggest source of energy by 2024, said Ministry of Knowledge Economy in a statement Tuesday. As a result, nuclear energy will provide 48.5% of the nation's energy consumption by the target year from the current 32%, the Ministry of Knowledge Economy said in a long-term national energy development plan
  • Coal is currently the biggest source of energy in South Korea that meets 42% of the nation's energy needs
  • Renewable energy sources like solar and wind power will also provide 8.9% of the nation's energy needs by 2024 compared with the current 1.3%, it said.

Nuclear safety: A dangerous veil of secrecy [11Aug11] - 0 views

  • There are battles being fought on two fronts in the five months since a massive earthquake and tsunami damaged the Daiichi nuclear power plant in Fukushima, Japan. On one front, there is the fight to repair the plant, operated by the Tokyo Electric Power Company (TEPCO) and to contain the extent of contamination caused by the damage. On the other is the public’s fight to extract information from the Japanese government, TEPCO and nuclear experts worldwide.
  • The latter battle has yielded serious official humiliation, resulting high-profile resignations, scandals, and promises of reform in Japan’s energy industry whereas the latter has so far resulted in a storm of anger and mistrust. Even most academic nuclear experts, seen by many as the middle ground between the anti-nuclear activists and nuclear lobby itself, were reluctant to say what was happening: That in Fukushima, a community of farms, schools and fishing ports, was experiencing a full-tilt meltdown, and that, as Al Jazeera reported in June, that the accident had most likely caused more radioactive contamination than Chernobyl
  • As recently as early August, those seeking information on the real extent of the damage at the Daiichi plant and on the extent of radioactive contamination have mostly been reassured by the nuclear community that there’s no need to worry.
  • ...29 more annotations...
  • The money trail can be tough to follow - Westinghouse, Duke Energy and the Nuclear Energy Institute (a "policy organisation" for the nuclear industry with 350 companies, including TEPCO, on its roster) did not respond to requests for information on funding research and chairs at universities. But most of the funding for nuclear research does not come directly from the nuclear lobby, said M.V. Ramana, a researcher at Princeton University specialising in the nuclear industry and climate change. Most research is funded by governments, who get donations - from the lobby (via candidates, political parties or otherwise).
  • “There's a lot of secrecy that can surround nuclear power because some of the same processes can be involved in generating electricity that can also be involved in developing a weapon, so there's a kind of a veil of secrecy that gets dropped over this stuff, that can also obscure the truth” said Biello. "So, for example in Fukushima, it was pretty apparent that a total meltdown had occurred just based on what they were experiencing there ... but nobody in a position of authority was willing to say that."
  • This is worrying because while both anti-nuclear activists and the nuclear lobby both have openly stated biases, academics and researchers are seen as the middle ground - a place to get accurate, unbiased information. David Biello, the energy and climate editor at Scientific American Online, said that trying to get clear information on a scenario such as the Daiichi disaster is tough.
  • "'How is this going to affect the future of nuclear power?'That’s the first thought that came into their heads," said Ramana, adding, "They basically want to ensure that people will keep constructing nuclear power plants." For instance, a May report by MIT’s Center For Advanced Nuclear Energy Systems (where TEPCO funds a chair) points out that while the Daiichi disaster has resulted in "calls for cancellation of nuclear construction projects and reassessments of plant license extensions" which might "lead to a global slow-down of the nuclear enterprise," that  "the lessons to be drawn from the Fukushima accident are different."
  • "In the United States, a lot of the money doesn’t come directly from the nuclear industry, but actually comes from the Department of Energy (DOE). And the DOE has a very close relationship with the industry, and they sort of try to advance the industry’s interest," said Ramana. Indeed, nuclear engineering falls under the "Major Areas of Research" with the DOE, which also has nuclear weapons under its rubric. The DOE's 2012 fiscal year budge request to the US Congress for nuclear energy programmes was $755m.
  • "So those people who get funding from that….it’s not like they (researchers) want to lie, but there’s a certain amount of, shall we say, ideological commitment to nuclear power, as well as a certain amount of self-censorship."  It comes down to worrying how their next application for funding might be viewed, he said. Kathleen Sullivan, an anti-nuclear specialist and disarmament education consultant with the United Nations Office of Disarmament Affairs, said it's not surprising that research critical of the nuclear energy and weapons isn't coming out of universities and departments that participate in nuclear research and development.
  • "It (the influence) of the nuclear lobby could vary from institution to institution," said Sullivan. "If you look at the history of nuclear weapons manufacturing in the United States, you can see that a lot of research was influenced perverted, construed in a certain direction."
  • Sullivan points to the DOE-managed Lawrence Berkeley National Laboratory at the University of California in Berkley (where some of the research for the first atomic bomb was done) as an example of how intertwined academia and government-funded nuclear science are.
  • "For nuclear physics to proceed, the only people interested in funding it are pro-nuclear folks, whether that be industry or government," said Biello. "So if you're involved in that area you've already got a bias in favour of that technology … if you study hammers, suddenly hammers seem to be the solution to everything."
  • And should they find results unfavourable to the industry, Ramana said they would "dress it up in various ways by saying 'Oh, there’s a very slim chance of this, and here are some safety measure we recommend,' and then the industry will say, 'Yeah,yeah, we’re incorporating all of that.'" Ramana, for the record, said that while he's against nuclear weapons, he doesn't have a moral position on nuclear power except to say that as a cost-benefit issue, the costs outweigh the benefits, and that "in that sense, expanding nuclear power isn't a good idea." 
  • The Center for Responsive Politics - a non-partisan, non-profit elections watchdog group – noted that even as many lobbying groups slowed their spending the first quarter of the year, the Nuclear industry "appears to be ratcheting up its lobbying" increasing its multi-million dollar spending.
  • Among the report's closing thoughts are concerns that "Decision-making in the  immediate aftermath of a major crisis is often influenced by emotion," and whether"an accident like Fukushima, which is so far beyond design basis, really warrant a major overhaul of current nuclear safety regulations and practises?" "If so," wonder the authors, "When is safe safe enough? Where do we draw the line?"
  • The Japanese public, it seems, would like some answers to those very questions, albeit from a different perspective.  Kazuo Hizumi, a Tokyo-based human rights lawyer, is among those pushing for openness. He is also an editor at News for the People in Japan, a news site advocating for transparency from the government and from TEPCO. With contradicting information and lack of clear coverage on safety and contamination issues, many have taken to measuring radiation levels with their own Geiger counters.
  • "The public fully trusted the Japanese Government," said Hizumi. But the absence of "true information" has massively diminished that trust, as, he said, has the public's faith that TEPCO would be open about the potential dangers of a nuclear accident.
  • A report released in July by Human Rights Now highlights the need for immediately accessible information on health and safety in areas where people have been affected by the disaster, including Fukushima, especially on the issues of contaminated food and evacuation plans.
  • A 'nuclear priesthood' Biello describes the nuclear industry is a relatively small, exclusive club.
  • The interplay between academia and also the military and industry is very tight. It's a small community...they have their little club and they can go about their business without anyone looking over their shoulder. " This might explain how, as the Associated Press reported in June, that the U.S. Nuclear Regulatory Commission was "working closely with the nuclear power industry to keep the nationalise ageing reactors operating within standards or simply failing to enforce them."
  • However, with this exclusivity comes a culture of secrecy – "a nuclear priesthood," said Biello, which makes it very difficult to parse out a straightforward answer in the very technical and highly politicised field.  "You have the proponents, who believe that it is the technological salvation for our problems, whether that's energy, poverty, climate change or whatever else. And then you have opponents who think that it's literally the worst thing that ever happened and should be immediately shut back up in a box and buried somewhere," said Biello, who includes "professors of nuclear engineering and Greenpeace activists" as passionate opponents on the nuclear subject.
  • In fact, one is hard pressed to find a media report quoting a nuclear scientist at any major university sounding the alarms on the risks of contamination in Fukushima. Doing so has largely been the work of anti-nuclear activists (who have an admitted bias against the technology) and independent scientists employed by think tanks, few of whom responded to requests for interviews.
  • So, one's best bet, said Biello, is to try and "triangulate the truth" - to take "a dose" from anti-nuclear activists, another from pro-nuclear lobbyists and throw that in with a little bit of engineering and that'll get you closer to the truth. "Take what everybody is saying with a grain of salt."
  • Since World War II, the process of secrecy – the readiness to invoke "national security" - has been a pillar of the nuclear establishment…that establishment, acting on the false assumption that "secrets" can be hidden from the curious and knowledgeable, has successfully insisted that there are answers which cannot be given and even questions which cannot be asked. The net effect is to stifle debate about the fundamental of nuclear policy. Concerned citizens dare not ask certain questions, and many begin to feel that these matters which only a few initiated experts are entitled to discuss.  If the above sounds like a post-Fukushima statement, it is not. It was written by Howard Morland for the November 1979 issue of The Progressive magazine focusing on the hydrogen bomb as well as the risks of nuclear energy.
  • The US government - citing national security concerns - took the magazine to court in order to prevent the issue from being published, but ultimately relented during the appeals process when it became clear that the information The Progressive wanted to publish was already public knowledge and that pursuing the ban might put the court in the position of deeming the Atomic Energy Act as counter to First Amendment rights (freedom of speech) and therefore unconstitutional in its use of prior restraint to censor the press.
  • But, of course, that's in the US, although a similar mechanism is at work in Japan, where a recently created task force aims to "cleanse" the media of reportage that casts an unfavourable light on the nuclear industry (they refer to this information as "inaccurate" or a result of "mischief." The government has even go so far as to accept bids from companies that specialise in scouring the Internet to monitor the Internet for reports, Tweets and blogs that are critical of its handling of the Daiichi disaster, which has presented a unique challenge to the lobby there.
  • "They do not know how to do it," he said of some of the community groups and individuals who have taken to measure contamination levels in the air, soil and food
  •  Japan's government has a history of slow response to TEPCO's cover-ups. In 1989, that Kei Sugaoka, a nuclear energy at General Electric who inspected and repaired plants in Japan and elsewhere, said he spotted cracks in steam dryers and a "misplacement" or 180 degrees in one dryer unit. He noticed that the position of the dryer was later omitted from the inspection record's data sheet. Sugaoka told a Japanese networkthat TEPCO had instructed him to "erase" the flaws, but he ultimately wrote a whistleblowing letter to METI, which resulted in the temporary 17 TEPCO reactors, including ones at the plant in Fukushima.
  • the Japanese nuclear lobby has been quite active in shaping how people see nuclear energy. The country's Ministry of Education, together with the Natural Resources Ministry (of of two agencies under Japan's Ministry of Economy, Trade and Industry - METI - overseeing nuclear policies) even provides schools with a nuclear energy information curriculum. These worksheets - or education supplements - are used to inform children about the benefits of nuclear energy over fossil fuels.
  • There’s reason to believe that at least in one respect, Fukushima can’t and won’t be another Chernobyl, at least due to the fact that the former has occurred in the age of the Internet whereas the latter took place in the considerably quaint 80s, when a car phone the size of a brick was considered the height of communications technology to most. "It (a successful cover up) is definitely a danger in terms of Fukushima, and we'll see what happens. All you have to do is look at the first couple of weeks after Chernobyl to see the kind of cover up," said Biello. "I mean the Soviet Union didn't even admit that anything was happening for a while, even though everybody was noticing these radiation spikes and all these other problems. The Soviet Union was not admitting that they were experiencing this catastrophic nuclear failure... in Japan, there's a consistent desire, or kind of a habit, of downplaying these accidents, when they happen. It's not as bad as it may seem, we haven't had a full meltdown."
  • Fast forward to 2011, when video clips of each puff of smoke out of the Daiichi plant make it around the world in seconds, news updates are available around the clock, activists post radiation readings on maps in multiple languages and Google Translate picks up the slack in translating every last Tweet on the subject coming out of Japan.
  • it will be a heck of a lot harder to keep a lid on things than it was 25 years ago.

Economic Aspects of Nuclear Fuel Reprocessing [12Jul05] - 0 views

  • On Tuesday, July 12, the Energy Subcommittee of the House Committee on Science will hold a hearing to examine whether it would be economical for the U.S. to reprocess spent nuclear fuel and what the potential cost implications are for the nuclear power industry and for the Federal Government. This hearing is a follow-up to the June 16 Energy Subcommittee hearing that examined the status of reprocessing technologies and the impact reprocessing would have on energy efficiency, nuclear waste management, and the potential for proliferation of weapons-grade nuclear materials.
  • Dr. Richard K. Lester is the Director of the Industrial Performance Center and a Professor of Nuclear Science and Engineering at the Massachusetts Institute of Technology. He co-authored a 2003 study entitled The Future of Nuclear Power. Dr. Donald W. Jones is Vice President of Marketing and Senior Economist at RCF Economic and Financial Consulting, Inc. in Chicago, Illinois. He co-directed a 2004 study entitled The Economic Future of Nuclear Power. Dr. Steve Fetter is the Dean of the School of Public Policy at the University of Maryland. He co-authored a 2005 paper entitled The Economics of Reprocessing vs. Direct Disposal of Spent Nuclear Fuel. Mr. Marvin Fertel is the Senior Vice President and Chief Nuclear Officer at the Nuclear Energy Institute.
  • 3. Overarching Questions  Under what conditions would reprocessing be economically competitive, compared to both nuclear power that does not include fuel reprocessing, and other sources of electric power? What major assumptions underlie these analyses?  What government subsidies might be necessary to introduce a more advanced nuclear fuel cycle (that includes reprocessing, recycling, and transmutation—''burning'' the most radioactive waste products in an advanced reactor) in the U.S.?
  • ...13 more annotations...
  • 4. Brief Overview of Nuclear Fuel Reprocessing (from June 16 hearing charter)  Nuclear reactors generate about 20 percent of the electricity used in the U.S. No new nuclear plants have been ordered in the U.S. since 1973, but there is renewed interest in nuclear energy both because it could reduce U.S. dependence on foreign oil and because it produces no greenhouse gas emissions.  One of the barriers to increased use of nuclear energy is concern about nuclear waste. Every nuclear power reactor produces approximately 20 tons of highly radioactive nuclear waste every year. Today, that waste is stored on-site at the nuclear reactors in water-filled cooling pools or, at some sites, after sufficient cooling, in dry casks above ground. About 50,000 metric tons of commercial spent fuel is being stored at 73 sites in 33 states. A recent report issued by the National Academy of Sciences concluded that this stored waste could be vulnerable to terrorist attacks.
  • Under the current plan for long-term disposal of nuclear waste, the waste from around the country would be moved to a permanent repository at Yucca Mountain in Nevada, which is now scheduled to open around 2012. The Yucca Mountain facility continues to be a subject of controversy. But even if it opened and functioned as planned, it would have only enough space to store the nuclear waste the U.S. is expected to generate by about 2010.  Consequently, there is growing interest in finding ways to reduce the quantity of nuclear waste. A number of other nations, most notably France and Japan, ''reprocess'' their nuclear waste. Reprocessing involves separating out the various components of nuclear waste so that a portion of the waste can be recycled and used again as nuclear fuel (instead of disposing of all of it). In addition to reducing the quantity of high-level nuclear waste, reprocessing makes it possible to use nuclear fuel more efficiently. With reprocessing, the same amount of nuclear fuel can generate more electricity because some components of it can be used as fuel more than once.
  • The greatest drawback of reprocessing is that current reprocessing technologies produce weapons-grade plutonium (which is one of the components of the spent fuel). Any activity that increases the availability of plutonium increases the risk of nuclear weapons proliferation.  Because of proliferation concerns, the U.S. decided in the 1970s not to engage in reprocessing. (The policy decision was reversed the following decade, but the U.S. still did not move toward reprocessing.) But the Department of Energy (DOE) has continued to fund research and development (R&D) on nuclear reprocessing technologies, including new technologies that their proponents claim would reduce the risk of proliferation from reprocessing.
  • The report accompanying H.R. 2419, the Energy and Water Development Appropriations Act for Fiscal Year 2006, which the House passed in May, directed DOE to focus research in its Advanced Fuel Cycle Initiative program on improving nuclear reprocessing technologies. The report went on to state, ''The Department shall accelerate this research in order to make a specific technology recommendation, not later than the end of fiscal year 2007, to the President and Congress on a particular reprocessing technology that should be implemented in the United States. In addition, the Department shall prepare an integrated spent fuel recycling plan for implementation beginning in fiscal year 2007, including recommendation of an advanced reprocessing technology and a competitive process to select one or more sites to develop integrated spent fuel recycling facilities.''
  • During floor debate on H.R. 2419, the House defeated an amendment that would have cut funding for research on reprocessing. In arguing for the amendment, its sponsor, Mr. Markey, explicitly raised the risks of weapons proliferation. Specifically, the amendment would have cut funding for reprocessing activities and interim storage programs by $15.5 million and shifted the funds to energy efficiency activities, effectively repudiating the report language. The amendment was defeated by a vote of 110–312.
  • But nuclear reprocessing remains controversial, even within the scientific community. In May 2005, the American Physical Society (APS) Panel on Public Affairs, issued a report, Nuclear Power and Proliferation Resistance: Securing Benefits, Limiting Risk. APS, which is the leading organization of the Nation's physicists, is on record as strongly supporting nuclear power. But the APS report takes the opposite tack of the Appropriations report, stating, ''There is no urgent need for the U.S. to initiate reprocessing or to develop additional national repositories. DOE programs should be aligned accordingly: shift the Advanced Fuel Cycle Initiative R&D away from an objective of laying the basis for a near-term reprocessing decision; increase support for proliferation-resistance R&D and technical support for institutional measures for the entire fuel cycle.''  Technological as well as policy questions remain regarding reprocessing. It is not clear whether the new reprocessing technologies that DOE is funding will be developed sufficiently by 2007 to allow the U.S. to select a technology to pursue. There is also debate about the extent to which new technologies can truly reduce the risks of proliferation.
  •  It is also unclear how selecting a reprocessing technology might relate to other pending technology decisions regarding nuclear energy. For example, the U.S. is in the midst of developing new designs for nuclear reactors under DOE's Generation IV program. Some of the potential new reactors would produce types of nuclear waste that could not be reprocessed using some of the technologies now being developed with DOE funding.
  • 5. Brief Overview of Economics of Reprocessing
  • The economics of reprocessing are hard to predict with any certainty because there are few examples around the world on which economists might base a generalized model.  Some of the major factors influencing the economic competitiveness of reprocessing are: the availability and cost of uranium, costs associated with interim storage and long-term disposal in a geologic repository, reprocessing plant construction and operating costs, and costs associated with transmutation, the process by which certain parts of the spent fuel are actively reduced in toxicity to address long-term waste management.
  • Costs associated with reducing greenhouse gas emissions from fossil fuel-powered plants could help make nuclear power, including reprocessing, economically competitive with other sources of electricity in a free market.
  •  It is not clear who would pay for reprocessing in the U.S.
  • Three recent studies have examined the economics of nuclear power. In a study completed at the Massachusetts Institute of Technology in 2003, The Future of Nuclear Power, an interdisciplinary panel, including Professor Richard Lester, looked at all aspects of nuclear power from waste management to economics to public perception. In a study requested by the Department of Energy and conducted at the University of Chicago in 2004, The Economic Future of Nuclear Power, economist Dr. Donald Jones and his colleague compared costs of future nuclear power to other sources, and briefly looked at the incremental costs of an advanced fuel cycle. In a 2003 study conducted by a panel including Matthew Bunn (a witness at the June 16 hearing) and Professor Steve Fetter, The Economics of Reprocessing vs. Direct Disposal of Spent Nuclear Fuel, the authors took a detailed look at the costs associated with an advanced fuel cycle. All three studies seem more or less to agree on cost estimates: the incremental cost of nuclear electricity to the consumer, with reprocessing, could be modest—on the order of 1–2 mills/kWh (0.1–0.2 cents per kilowatt-hour); on the other hand, this increase represents an approximate doubling (at least) of the costs attributable to spent fuel management, compared to the current fuel cycle (no reprocessing). Where they strongly disagree is on how large an impact this incremental cost will have on the competitiveness of nuclear power. The University of Chicago authors conclude that the cost of reprocessing is negligible in the big picture, where capital costs of new plants dominate all economic analyses. The other two studies take a more skeptical view—because new nuclear power would already be facing tough competition in the current market, any additional cost would further hinder the nuclear power industry, or become an unacceptable and unnecessary financial burden on the government.

Rossi's Self Sustaining One Megawatt Reactor [21Jul11] - 0 views

  • Almost everyone in the alternative energy community is aware of Andrea Rossi's cold fusion based E-Cat (Energy Catalyzer) technology. It is a game changer that allows vast amounts of energy to be produced by inducing a nuclear fusion process between small quantities of nickel powder and hydrogen gas. Instead of the reaction taking place in a gigantic multi-billion dollar experimental reactor, it takes place in a device that can fit on a table top. This technology seems to be everything to be hoped for in a revolutionary new source of energy to replace fossil fuels -- safe, cheap, environmentally friendly, and inexhaustible. 
  • It seems that as the launch of the technology approaches, the flow of information is accelerating. The information is coming from Defkalion Green Technologies Incorporated, Andrea Rossi himself, and from other sources. The following is a review of some of the breaking news.

  • Dear Alessandro Casali: This photo [shown in the opening of this PESN story] has been taken during the stress test of a series of E-Cats a couple of weeks ago, together with the Greek Scientist Christos Stremmenos. They are some of the E-Cats that will compound the 1 MW plant. In that phase the E-Cats were working making steam WITHOUT energy input. This is why you see us so focused (me and Stremmenos). The 1 MW plant, probably will work mostly without energy input, I suppose, because we are resolving the safety issues connected. The 4 red spots are pumps, the E-Cat clusters are hidden. The three characters in the photo are Prof. Sergio Focardi, Prof. Christos Stremmenos and me. Warm Regards, A.R.
  • Here is a comment on this topic from Rossi's blog, "The Journal of Nuclear Physics." http://www.journal-of-nuclear-physics.com/?p=501&cpage=2#comment-54414 
  • (I think the reason he uses the word "mostly" in the above post, is that the one megawatt plant will require input power to start. Also, if a reactor core starts to drift lower in output, power will be used for a few minutes to bring it back to a normal operating temperature. For the vast majority of the time, there will be no input power.) The fact that the one megawatt plant will use no input power (the vast majority of the time) is very important. This will be absolute -- beyond any doubt -- proof that the technology works as claimed. Simply put, the pathological skeptics and naysayers will not be able to refute that cold fusion is taking place.

Build baby build - new nuclear power plants[25Jul11] - 0 views

  • CBS News aired a short piece titled US heat wave causes new look at nuclear energy that is worth a look. Though it includes the obligatory appearance of a professional antinuclear activist – in this case, Dr. Edwin Lyman of the Union of Concerned Scientists – the story provides some encouraging clips of the massive quantities of dirt being moved by thousands of workers who are making preparations for Vogtle Units 3 and 4 in eastern Georgia.
  • The story also reminds people why some of us are so interested in building new nuclear power plants – we know how vital reliable electricity is. That knowledge is reinforced when power grids are stressed and when people die due to complications associated with heat exposure. We know that nuclear plants have a far better chance of being available when needed than the wind turbines that were AWOL during the heat wave because, darn it, when the heat domes hover, the air is still and muggy. If there was a reliable breeze we would not be so dependent on our air conditioners!
  • a comment that I provided to CBS regarding their story:Nuclear power plants have proven that they are safe neighbors. In more than 50 years of commercial operation, the total number of deaths from exposure to radiation from nuclear power plants around the entire world is less than 100. In contrast, thousands of people die every year from exposure to the hazardous waste products that fossil fuel plants dump into our atmosphere as a routine part of their operation.I like having the ability to use electricity on demand. I like having clean air. I like the idea that building new nuclear plants that can operate reliably for 60-80 years is resulting in new jobs for thousands of American mechanics, electricians, construction workers, engineers and procedure writers. (Disclosure: I fall into that last category and am currently part of a large team that is designing another version of a reactor that can keep itself under control for at least three days without any sources of electricity.)

  • Dr. Lyman is a professional antinuclear activist who has never actually operated a plant. He has a PhD in nuclear physics, but that does not mean that he ever studied anything about engineering or operations. It might not even mean that he studied anything about nuclear fuel.

Utility regulators scrutinize energy giants' nuclear energy plans- Florida [10Aug11] - 0 views

  • Florida Power & Light and Progress Energy are asking the Public Service Commission to sign on off their proposals to pass off about $355 million in nuclear energy-related costs to residents and businesses. The money would go to upgrade existing power plants, including one in St. Lucie County, and two cover the costs of new nuclear reactors that may not begin operating for at least another decade.
  • Hearings on the nuclear cost recovery plans are scheduled to begin this morning at 9:30 a.m in Tallahassee and can be viewed live on the internet at www.floridapsc.com or The Florida Channel’s website at www.thefloridachannel.org. The meeting will begin with a discussion of which documents will remain secret.
  • Juno Beach-based FPL is asking for about $196 million next year to help upgrade nuclear plants in St. Lucie and Miami-Dade counties and to move forward on a plan to build two new reactors at the Miami-Dade site known as “Turkey Point.” The energy companies and many state lawmakers the expansion of nuclear power is necessary to wean the state off fossil fuels and to save money for customers.

  • But attorneys for large businesses, consumers and environmental groups question the methodology the energy companies are using and whether customers will actually benefit in the long run.
  • The state Office of Public Counsel, which represents consumers, argues that FPL’s decisions to “fast track” the new reactors led to inflated costs – an argument FPL disputes. If approved, FPL’s request would result in a $2.09 increase next year for residential customers, based on 1,000 kilowatt hours of electricity usage.

Swiss parliament approves nuclear plant phase out [28Sep11] - 0 views

  • The Swiss parliament's upper house on Wednesday approved plans to phase out the country's nuclear plants over the next two decades in the wake of the Fukushima disaster in Japan.It followed a June vote by the lower chamber to back an exit from nuclear energy recommended by the government, which had earlier frozen plans for a new construction programme after the Fukushima atomic plant explosion.
  • Bern said it would count on the development of its already considerable hydro-electric plants and other renewable energy to make up for the loss of nuclear power, while not ruling out importing electricity.If necessary the country could also fall back on electricity produced by fossil fuels, a statement added, while still respecting targets set under Switzerland's climate change policy.Under the government's recommendation, the first nuclear plant to be shut down would be Beznau I in 2019, followed by Beznau II and Muehleberg in 2022, Goegen in 2029 and Leibstadt in 2034.
  • The government predicted that such a programmed phasing out nuclear energy would favour businesses involved in green technology, boost employment and help Switzerland deal with expected rising electricity prices in Europe.Initial calculations estimate that the cost of reshaping the country's energy resources, offset by measures to cut consumption, would cost the country between 0.4 percent and 0.7 percent of gros s domestic product per year.Environment and Energy Minister Doris Leuthard also noted that nuclear energy was anyway becoming more expensive, due to the rising cost of making plants safer and more secure.However, the move to halt atomic energy was opposed by the federation of Swiss businesses EconomieSuisse, which had slammed it as an "irresponsible decision."The association of Swiss electricity companies applauded the decision for a progressive end to nuclear energy, rather than an immediate stop."The continuation of these plants gives us time to find solutions amid a shortage as well as implement more efficient measures," it said.

  • However, the association stressed that the population must be given a say in the decision.
  • Environmental group Green Cross International's president Mikhail Gorbachev meanwhile welcomed Switzerland's decision."I applaud Switzerland for taking this brave step towards ending its reliance on nuclear energy," he said in a statement.

Cheap Solar Paint Takes a Giant Step Closer to Reality [10Apr10] - 0 views

  • For all the excitement over low cost solar power, much of it is still in the development stage backed by government resources and has yet to prove that it can compete on the market with cheap fossil fuels.   However some private investors are starting to bet on low cost solar in a big way.  Among them is tech specialist Len Batterson, whose startup  NextGen Solar is kicking into gear.NextGen Solar will use nanoscale solar “paint” technology developed by Argonne National Laboratory, with the goal of lowering production costs while increasing efficiency compared to thin-film photovoltaic materials.
  • Many Roads to Cost-Competitive SolarFrom turnkey solar kits to the use of low-cost solar materials, there are many different angles from which to push solar into the competitive energy market.  A solar paint that can be economically applied to different surfaces is one solution.  The National Renewable Energy Laboratory is already working on a silicon based solar ink, and The University of Texas is developing spray-on solar cells.  According to chicagobusiness.com writer Paul Merrion, Argonne’s solar technology can be applied to many types of building surfaces, including windows.  It goes on like paint, then dries to form microscopic interconnected solar cells.

Alec Baldwin Knocks Nuclear Power, Calls Reactors 'Filthy' [02Sep11] - 0 views

  • And there is some evidence that the dangers of nuclear power have been underestimated in the past. An Associated Press analysis of a preliminary government report on nuclear reactor safety found that the risk of an earthquake causing a severe accident at a U.S. nuclear plant is as much as 24 times greater than previously thought, suggesting an urgent need for upgrades.
  • But for some opponents of nuclear power, no amount of planning or patching is enough. The risks to the environment and human health, they say, far outweigh whatever benefits nuclear power might have to offer -- even if those benefits include reducing the nation's reliance on fossil fuels.
  • Among those critics is the actor Alec Baldwin, whose thoughts on the subject carry added weight with his admitted interest in entering politics. Earlier this month, he told The New York Times that while a run is not imminent, he has his eye on the mayor's office.

Japan could rebuild faster with renewables, says report [12Apr11] - 0 views

  • The Nautilus Institute for Security and Sustainability has an answer, and it's anything but business as usual. By deploying a mix of renewables and energy efficiency technology, they argue, Japan's need for electricity could be met three years sooner than through nuclear and conventional fossil fuel power.
  • All told, Japan's earthquake and tsunami have knocked out at least 15,000 megawatts of electricity generating capacity -- that's greater than the total summer peak demand for all of New York City
  • Rebuilding with renewables would restore the country’s capacity more cleanly. The initial cost would be higher but spread across the lifetime of the initiatives, it would only amount to an additional 10 percent more per year. The study authors argue this would be more than justified by the positive economic impact of meeting Japan's power needs years before conventional plants could be brought on-line.
  • ...1 more annotation...
  • Japan has to rebuild its infrastructure anyway -- some estimates put the total cost at $310 billion -- so the Nautilus Institute argues that this is an opportunity to deploy a more modern version of what came before. Will Japan seize the opportunity to deploy a smart grid that can be used to balance power production and consumption, and so enable robust energy infrastructure like rooftop solar?

nuclear energy America: Five realities of nuclear energy that should reassure Americans... - 0 views

  • As we continue to learn about and understand the implications of the Fukushima event, here are five realities that are sometimes lost in the debate:Eliminating nuclear energy is not realistic if we want to maintain our quality of life.
  • omes from nuclear energy, while about 68 percent comes from greenhouse gas-emitting fossil fuels like coal. Nuclear plants continuously produce large amounts of electricity and make up about 70 percent of America's emissions-free generation. Wind and solar make up 8 percent and .01 percent, respectively. Solar, wind and nuclear energy all play a valuable role in our energy mix, but currently, nuclear plants are the only large sources of emissions-free generation that can provide the amount of power we need to keep our homes and businesses running 24 hours per day.Nuclear energy also helps keep electricity costs low. Including the costs of operations, maintenance and fuel, nuclear energy has the lowest production cost of any major energy source. For the past 15 years, the cost of nuclear fuel has remained steadily lower than oil, natural gas and even coal. Of course, these savings, and the benefits of being non-emitting, are realized by utility customers.
  • Day-to-day activities present a greater health threat than a local nuclear plant.The anti-nuclear activists often invoke perceived "dangers" associated with nuclear plants. A review of the facts, however, tells a vastly different story regarding actual risk.In 2010, almost 34,000 people in the United States died in auto accidents. That's about one death every 15 minutes. In the past 60 years, while nuclear energy supplied American electricity, annual fatalities from aircraft crashes ranged from a high of 3,214 deaths in 1972 to a low of 771 deaths in 2004.
  • ...6 more annotations...
  • Yet in the entire history of the nuclear industry, there have been three major reactor accidents: Three Mile Island in Pennsylvania, Chernobyl in Russia and Fukushima. And apart from Chernobyl — which was caused by a flawed reactor design that is not employed anywhere in the United States — no nuclear workers or members of the public have ever died as a result of exposure to radiation from a commercial nuclear plant. This fact is attributable to sound designs, strong construction, a culture in which safety always comes first, a highly trained, conscientious workforce, and rigorous government oversight.
  • Nuclear power plants are constantly upgraded.Unlike cars or appliances that are typically run until they break down, U.S. nuclear plants have a proactive aging-management program that replaces equipment well before it has the opportunity to malfunction. Using the car analogy, think of it this way: While the body of the car may have been manufactured years ago, its engine and safety systems are upgraded and rebuilt continuously with state-of-the-art components over time.In 2009 alone, the U.S. nuclear industry invested approximately $6.5 billion to upgrade plant systems with the latest technology. Continuous upgrades have always been the standard for U.S. nuclear plants for many reasons — most importantly protecting the health and safely of the public and workers. This industry considers continuous improvement to be a necessary investment rather than "optional" expense.
  • The amount of spent fuel is small and can be managed safely.In many cases, the issue of storing used fuel is discussed without proper context.Used nuclear fuel is in the form of solid pellets about the size of a pencil eraser. The fact is, the total amount of waste generated by the entire U.S. nuclear industry over more than 60 years of operation would fit in the area of one football field. For this entire time, we have safely and securely stored this fuel on-site in specially-designed pools and in strongly-engineered dry storage containers.
  • Nobody would argue that the on-site storage of used fuel is ideal. But it is a responsible option for now, since the relative amount of used fuel is so small; because multiple levels of safety and security protection have proven to be effective; more than 50 years of scientific research, engineering and experience proves that it can be stored with little environmental impact; and on-site storage is the only option utilities have until the federal government fulfills its responsibility to identify a long-term disposal solution.Moreover, only a small percentage of the available energy has been harvested from this fuel at the point when regulations require it to be stored on-site. This fuel should be recycled and re-used, as other countries have successfully concluded. But until political barriers in this country allow for this logical path, it must be stored on-site.
  • Nuclear plants have more government oversight than any other industry.The rigor and comprehensiveness of nuclear safety oversight in the United States is extraordinary. Our licensing and regulatory process is studied and emulated worldwide.Every nuclear power plant in the United States has multiple government inspectors on-site, year-round. They are top experts in the field and have unrestricted access to all vital areas of the plant, including plant records. In addition to these daily oversight activities, each plant frequently undergoes multiple evaluations and inspections that include detailed reviews of security, emergency planning, environmental protection, industrial safety, critical plant systems, plant culture and safety processes — all of which are aimed at ensuring the continued safe operation of these facilities.
  • Honest questioning from concerned citizens regarding nuclear energy is understandable. A thinking society should continuously strive for accurate, credible validation of its technologies. As to the safety and security of U.S. nuclear plants, the facts are reassuring. I firmly believe that these — and other facts — should be the basis for any discussion on the future of nuclear energy here in America.

Amano: New nuclear remains on the agenda [13Sep11] - 0 views

  • The worldwide use of nuclear energy will continue to grow despite the Fukushima Daiichi accident, the director general of the International Atomic Energy Agency (IAEA), Yukiya Amano, told a meeting of its Board of Governors. Non-proliferation concerns remain in some countries, he noted.
  • "We now expect the number of operating nuclear reactors in the world to increase by about 90 by 2030, in our low projection, or by around 350, in our high projection, compared to the current total of 432 reactors," Amano told the board. "This represents continuous and significant growth in the use of nuclear power, but at a slower growth rate than in our previous projections."
  • He noted that most of this growth will occur in countries already operating nuclear power plants, especially in Asia. "China and India will remain the main centres of expansion and their nuclear power capacities by 2030 are expected to be as projected before the accident, after a temporary period of slower growth," Amano said. "The projected slowdown in global growth reflects an accelerated phase-out of nuclear power in Germany, some immediate shutdowns and a government review of the planned expansion in Japan, and temporary delays in expansion in several other countries."   According to Amano, interest remains strong in countries considering introducing nuclear energy. He said that the factors that contributed to increasing interest in nuclear energy before the accident remain unchanged: "increasing global demand for energy, as well as concerns about climate change, dwindling reserves of oil and gas and uncertainty of supply of fossil fuels." However, he noted that "a few countries have cancelled or revised their plans, while others have taken a 'wait and see' approach."
  • ...2 more annotations...
  • Amano told the board that the situation at the Fukushima Daiichi site "remained very serious for many months," but the IAEA's assessment now is that the reactors are "essentially stable and the expectation is that the 'cold shutdown' of all the reactors will be achieved as planned."   Amano presented the IAEA board with a draft of a new Nuclear Safety Action Plan, the "result of an intensive process of consultations with member states." He told the meeting, "The draft Nuclear Safety Action Plan represents a significant step forward in strengthening nuclear safety. We must not lose our sense of urgency. I hope the draft action plan will be approved by the board and endorsed by the General Conference next week."
  • "In the aftermath of Fukushima Daiichi, the most important thing is to ensure transparency, build confidence, and meet the high expectations of the public. But it is actions, not words, that count. With this plan we will move from the planning phase to the implementation phase ... Further lessons will be learned and the plan will be updated accordingly."   "It will take rapid and visible improvements in nuclear safety - not just good intentions - to restore public confidence in nuclear power. The agency will play its central part with vigour."
