America Needs a Bunker to Store Its Mountain of Toxic TVs | via @Wired
The firefighters extinguished the blaze within a few hours, but the larger danger remains. The March 2 fire was just one symptom of enormous problem that's spreading across the country. As we move to flat screen TVs and computer displays, we're discarding our big, bulky old school televisions and CRT monitors, and they're piling up in warehouses like the one that caught fire in Parowan, with nowhere to go. These discarded screens aren't just a fire hazard. They're filled with lead and other toxic materials.
In California alone, more than 100 million pounds of leaded CRT monitors glass is recovered each year, according to CalRecycle, the state's recycling agency...Environmentalists say there's no obvious solution to the problem, but that means it's time for the government to step in. At the very least, we need a place where this growing pile of glass and lead can be cleaned and stored until we know what to do with it. We need a Yucca Mountain for all our CRTs.
Billions of Pounds of Leaded Glass
If you've ever hauled one of the bulky monitors that were universal before the advent of flat panel displays, you'll know that they are remarkably heavy. That's because, behind the screen, there's a big funnel of heavy leaded glass designed to be sturdy and to protect consumers from radiation leakage. The glass is recyclable, and for awhile, U.S. recyclers were able to ship it off for reuse in other countries.
But today, there are only a handful of places that will accept this leaded glass....

The $65 billion nuclear waste fiasco...storing nuclear waste at reactors sites “politically unsustainable.”
POLITICO....Industry argues that the damages are closer to $50 billion — which raises the bottom line to $65 billion including the money spent on Yucca.
The cost of the refunds is little known to the public, but it's such a huge liability that DOE tracks the figure closely. The government is still fighting the utilities' claims in court, but utilities have been racking up a string of wins.
The costs of inaction don't just include dollars. The lack of a final resting place for the waste means that each nuclear plant has to stockpile its own. Thousands of tons of waste are stranded at sites around the country, including at plants that have shut down.
"I'm trying to think of some fancy words but at the end of the day it's just a massive consumer rip-off," said Greg White, a regulator on the Michigan Public Service Commission who also heads the nuclear waste panel for the National Association of Regulatory Utility Commissioners. NARUC, which represents state-level regulators, won a legal victory this month when the D.C. Circuit Court of Appeals ordered DOE to stop collecting the fee.
Salo Zelermyer, a former George W. Bush-era DOE attorney who works at the law firm Bracewell & Giuliani, says the waste program has "plainly broken down" and that the government had made "no discernable progress towards its commitments."
Energy Secretary Ernest Moniz also expressed frustration this month, calling the system of storing nuclear waste at reactors sites "politically unsustainable."
"For nuclear energy to be competitive here in the U.S. and ensure its safety and security abroad, we have to address the problem of disposition of used nuclear fuel and high-level waste," Moniz said during a panel discussion at an American Nuclear Society meeting. He previously served on a blue-ribbon commission that advised Obama on changes to the nation's nuclear waste policy.
But like others in the Obama administration, Moniz maintains that Yucca Mountain is not "a workable option."
Congress chose the Nevada site in 1987 as the country's sole permanent nuclear repository, but it continues to draw fierce opposition from many of the state's residents and elected officials. One of its most powerful opponents is Senate Majority Leader Harry Reid (D-Nev.), who blocked funding for the project and pushed the Obama administration to kill it — something DOE did in 2010.
Reid and Sen. Ed Markey (D-Mass.) have long argued that the studies supporting the project were discredited because Congress short-circuited the site-selection process to focus solely on Yucca. The administration says the government needs to start over with a new waste site — and this time, the selection process must be "consent based" to win public acceptance.
"When this Administration took office, the timeline for opening Yucca Mountain had already been pushed back by two decades, stalled by public protest and legal opposition, with no end in sight," DOE spokeswoman Niketa Kumar said in an email.
Canada's nuclear waste disposal plan risks polluting the Great Lakes with toxic nuclear waste
"Neither the U.S. nor Canada can afford the risk of polluting the Great Lakes with toxic nuclear waste," U.S. Reps. Dan Kildee, Sander Levin, John Dingell and Gary Peters of Michigan said in a letter to a panel that is expected to make a recommendation next spring to Canada's federal government, which has the final say....The decision on the $1 billion Canadian project could influence the broader debate over burying nuclear waste deep underground, said Per Peterson, a nuclear engineering professor at the University of California at Berkeley, who served on a national commission that studied the waste issue in the United States. The U.S. government's plan for building a repository at Yucca Mountain in Nevada has been halted by stiff opposition.
"Demonstrating that this facility can be approved and operated safely is important because it can improve confidence that future high-level waste facilities also can be operated safely," Peterson said.
The Canadian "deep geologic repository" would be the only deep-underground storage facility in North America, aside from a military installation in New Mexico. Other U.S. radioactive waste landfills are shallow - usually 100 feet deep or less.
The most highly radioactive waste generated at nuclear plants is spent fuel, which wouldn't go into the Canadian chamber....Please continue reading from Great Lakes nuclear waste disposal plan makes odd allies - CBS News | shared via feedly mobile

U.S. Nuclear Power in Decline, billion$ at stake via @Sustainablog
The nuclear industry's troubles began well before the 1979 accident at Pennsylvania's Three Mile Island nuclear plant sowed public mistrust of atomic power. In 1957, the country's first commercial nuclear reactor was completed in Pennsylvania. By the mid-1960s, excitement over an energy source predicted to be "too cheap to meter" had created a frenzied rush to build reactors. But utilities soon pulled back on the throttle as the realities of construction delays and cost overruns sank in. Annual orders for new reactors, which peaked at more than 40 in 1973, fell sharply over the next several years. The two reactor orders placed in 1978 would be the last for three decades.
Of the 253 reactors that were ordered by 1978, 121 were canceled either before or during construction, according to the Union of Concerned Scientists' David Lochbaum. Nearly half of these were dropped by 1978. The reactors that were completed—the last of which came online in 1996—were over budget three-fold on average.
By the late 1990s, 28 reactors had permanently closed before their 40-year operating licenses expired. A number of factors played a role in this, including cost escalation, slower electricity demand growth, and a changing regulatory environment. Despite these closures, the United States was still left with 104 reactors totaling some 100 gigawatts (100,000 megawatts) of generating capacity—by far the most of any country.
Then, spurred on by new tax credits and loan guarantees promised in the 2005 Energy Policy Act—as well as by high prices for natural gas, a competing fuel—the industry has recently had visions of a "nuclear renaissance." By 2009, utilities were planning more than 30 new reactors. But in the years since, the vast majority of these plans have been shelved. Even with huge subsidies, private lenders still see new nuclear projects as too risky to finance. Meanwhile, the U.S. shale gas production boom sent natural gas prices plummeting, further darkening nuclear's prospect.
In 2012, the U.S. Nuclear Regulatory Commission (NRC) approved four new reactors for construction, two each at the Vogtle plant in Georgia and the Summer plant in South Carolina. These reactors are all of the same commercially untested design, purportedly quicker to build than previous plants. Both projects benefit from fairly new state laws that shift the economic risk to ratepayers. These "advanced cost recovery" laws, also passed in Florida and North Carolina, allow utilities to raise their customers' rates to pay for new nuclear plants during and even before construction—regardless of whether the reactors are ever finished.
Construction at both sites began in March 2013. Even as the first concrete was poured at the $14-billion Vogtle project, it was reportedly 19 months behind schedule and more than $1 billion over budget. The Summer project, a $10 billion endeavor, also quickly ran into problems. In June its owner, Scana Corp., admitted that it was running about a year behind and faced $200 million in additional costs. With these delays, the earliest projected completion date for any of these reactors is some time in late 2017.
The only other reactor currently under construction in the United States is Watts Bar 2 in Tennessee. It broke ground in 1972 and, after being on hold for two decades, was finally scheduled for completion in 2012. But that year, the owner—the Tennessee Valley Authority—announced it would be delayed again until 2015 and that the cost of the project would rise by up to 80 percent, to $4.5 billion.
Several utilities have recently dropped plans for new reactors or for "uprates," where an existing reactor's generating capacity is increased. For example, in May 2013 Duke Energy suspended its application to the NRC for two proposed reactors in North Carolina, citing slow electricity demand growth. Then in August, Duke pulled plans for a two-reactor, $24.7-billion project in Florida, on which it had already spent—and mostly recovered from its ratepayers—$1 billion. The company worried that mid-2013 amendments to the state's advanced cost recovery law would make it more difficult to fund ongoing projects with higher customer bills.
In June, the nation's largest nuclear utility, Exelon, canceled uprate projects at plants in Pennsylvania and Illinois. (These are two of at least six uprates dropped by utilities in 2013 as of early September.) Just over a month later, the French utility Électricité de France (EDF) announced it was bowing out of a partnership with Exelon that operates nuclear plants in New York and Maryland. In fact, EDF will no longer pursue U.S. nuclear projects at all, instead focusing its U.S. efforts on renewables.
This year has also already witnessed the permanent shutdown of four reactors totaling 3.6 gigawatts of capacity. The first to fall was Duke's Crystal River reactor in Florida. Although the plant was licensed to run until 2016, Duke decided to close it rather than pay for needed repairs. Then Dominion Energy's 39-year-old Kewaunee reactor in Wisconsin closed, citing competition from low gas prices. It had recently been approved to operate through 2033. And in June, Southern California Edison shuttered its two San Onofre reactors after 18 months of being offline due to a leak in a brand new steam generator. These retirements leave the United States with 100 reactors, averaging 32 years in operation. (France is second, with 58 reactors.)
More closures will soon follow, particularly among the roughly half of U.S. reactors in so-called merchant areas where nuclear competes with other technologies and prices are set by the market. A 2013 report by Mark Cooper at the Vermont Law School indicates that there are nine merchant reactors that, like Kewaunee, were granted 20-year life extensions but are especially at risk of closure. Epitaphs are already being written for two of them: Vermont's lone nuclear power plant will close in 2014, and the country's oldest reactor, Oyster Creek in New Jersey, will retire by 2019.
"Regulated" areas, where state authorities set electricity prices such that nuclear operators are guaranteed a profit, contain the rest of the U.S. reactors. Even for many of these plants, the economics may not allow for survival much longer. According to Credit Suisse, the cost of operating and maintaining the aging reactor fleet is rising at 5 percent a year and the nuclear fuel cost is growing even faster, at 9 percent annually. Wind and solar power costs, on the other hand, continue to drop as their electric output grows rapidly.
Dealing with nuclear waste is another expensive proposition. Over the past 30 years, the U.S. government has spent some $15 billion trying to approve a central repository for nuclear waste, and for most of that time the only site under consideration has been Nevada's Yucca Mountain. Amid concerns about the site's safety and its extreme unpopularity in Nevada, the Obama administration has moved to abandon the project entirely and explore other options.
A federal appeals court ruled in August 2013 that the NRC must resume reviewing the site's suitability. In the meantime, the waste keeps accumulating. The 75,000 tons of waste now stored at 80 temporary sites in 35 states is projected to double by 2055. All this has implications for nuclear power's prospects for expansion: nine states, including California, Connecticut, and Illinois, have prohibited new nuclear plants until a solution to the waste issue is found.
The low level of liability for nuclear operators in case of an accident also puts taxpayers on the hook. Plant owners pay into an insurance pool of just $12 billion; the public would cover any further damages. For comparison, cleanup and compensation for the 2011 Fukushima nuclear disaster in Japan is projected to cost at least $60 billion. The Natural Resources Defense Council estimates that a catastrophic accident at New York's Indian Point plant could cost 10 to 100 times that amount. This risk will be underscored on September 29, 2013, when one of Indian Point's two reactors becomes the first ever to operate with an expired license.
If the reactors now under construction in Georgia and South Carolina actually come online, they are projected to generate electricity that is much more expensive than nearly any other source, including wind and solar power. New nuclear plants are simply too expensive to replace the aging fleet. And with uprate proposals for existing reactors being pulled, it appears the industry cannot depend on this option to increase capacity much either.
The NRC has approved 20-year operating life extensions for more than two thirds of existing U.S. reactors; most of the rest will probably be granted extensions as well. Even if these units reach the end of their licensed life—which past experience says is unlikely—if no new plants come online to replace them, the last U.S. reactor will be shut down by the late 2050s. Any industry hopes ride heavily on the success of the Vogtle and Summer projects. As U.S. Energy Secretary Ernest Moniz said in a recent interview, if these plants now under construction keep racking up huge cost overruns and delays, "it is very hard to see a future for nuclear power plants" in the United States.

Appeals court: Nuclear Regulatory Commission has been violating federal law by delaying a decision on a proposed nuclear waste dump in Nevada - Yahoo! News
WASHINGTON (AP) — In a rebuke to the Obama administration, a federal appeals court ruled Tuesday that the Nuclear Regulatory Commission has been violating federal law by delaying a decision on a proposed nuclear waste dump in Nevada.
By a 2-1 vote, the U.S. Court of Appeals for the District of Columbia ordered the commission to complete the licensing process and approve or reject the Energy Department's application for a never-completed waste storage site at Nevada's Yucca Mountain.
In a sharply worded opinion, the court said the nuclear agency was "simply flouting the law" when it allowed the Obama administration to continue plans to close the proposed waste site 90 miles northwest of Las Vegas. The action goes against a federal law designating Yucca Mountain as the nation's nuclear waste repository.
"The president may not decline to follow a statutory mandate or prohibition simply because of policy objections," Judge Brett M. Kavanaugh wrote in a majority opinion, which was joined Judge A. Raymond Randolph. Chief Judge Merrick B. Garland dissented.
The appeals court said the case has important implications for the separation of powers between the executive and legislative branches of government.
"It is no overstatement to say that our constitutional system of separation of powers would be significantly altered if we were to allow executive and independent agencies to disregard federal law in the manner asserted in this case by the Nuclear Regulatory Commission," Kavanaugh wrote. "The commission is simply defying a law enacted by Congress ... without any legal basis."
A spokesman for the NRC said Tuesday the agency was reviewing the decision. He declined further comment.
Energy Secretary Ernest Moniz said the Energy Department was not a party to the lawsuit, but he characterized the Yucca Mountain project as "a complete stalemate." He said he saw no evidence of that changing.
"Currently we do not have funding," he told reporters at a clean energy conference Tuesday in Las Vegas.
The court's decision was hailed by supporters of the Yucca site, which has been the focus of a dispute that stretches back more than three decades. The government has spent an estimated $15 billion on the site but has never completed it. No waste is stored there.
"This decision reaffirms a fundamental truth: The president is not above the law," said South Carolina Attorney General Alan Wilson. The Obama administration "cannot pick and choose which laws to follow and which to ignore," Wilson said.

Oilsand taxes will pay for Molten Salt Reactor development. MSR will provide steam for $200 billion
Terrestrial Energy Inc. ("TEI") was founded in late 2012, and is domiciled in Ontario, Canada. Its mission is to commercialize its patent-pending Molten Salt Reactor technology in Canada. The company has been formed around Dr. David LeBlanc, and his intellectual property portfolio. Dr. LeBlanc is the internationally recognized expert on MSR technology.
LeBlanc is going to develop the Integral Molten Salt Reactor, or IMSR. The goal is to commercialize the Terrestrial reactor by 2021. They have oilsand partners.
David LeBlanc had a presentation - Molten Salt Reactors and the Oil Sands:
Odd Couple or Key to North American Energy Independence?
Molten Salt Reactor Advantages
* Many potential variations but sharing unique advantages
* Increased Safety
* Reduced Costs
* Resource Sustainability
* Greatly Reduced Long Lived Wastes
* Fission products almost all benign after a few hundred years
* The transuranics (Np,Pu,Am,Cm) are the real issue and reason for "Yucca Mountains"
* All designs produce less TRUs and can be kept in or recycled back into the reactor to fission off (IMSR will keep the waste inside)
* Over a thousand fold improvement over conventional "Once Through"
Molten Salt and Oilsands
* Using nuclear produced steam for Oil Sands production long studied
* Vast majority of oil only accessible by In-Situ methods
* No turbine island needed so 30% to 40% the capital cost saved (instead of steam to turbine for electricity just send it underground to produce oil from oilsands)
* Oil sands producers expected to pay 200 Billion$ on carbon taxes over the next 35 years, funds mandated to be spent on cleantech initiatives
* Canada Oil Sands in ground reserves of 2 trillion barrels, current estimate 10% recoverable (likely much higher with cheaper steam)
* 64 GWth nuclear to add 6.4 million bbls/day (200B$/year revenue)
* 64 GWth needed as about 200 small 300MWth MSRs
* Oil Sands a bridge to MSRs then with time, MSRs a bridge to not needing oil
IMSR design
* No fuel fabrication cost or salt processing = extremely low fuel costs
* Under 0.1 cents/kwh
* Right size reactors, right pressure stea
The IMSR is a simplfied design denature molten salt reactor design that takes features of the Small Modular Advanced High Temperature Reactor (SmAHTR)
With the right combination of power density and core design Terrestrial could build the IMSR with upwards of six times the electrical output of the same size vessel as SmAHTR. It would require replacing the graphite core every four years. The fuel would reside temporarily in a holding tank during the core swap. That marks an improvement over the SmAHTR concept, which requires a swap of the solid fuel core every four years.
LeBlanc envisions IMSR reactor sizes ranging from 25 MWe to 300 MWe.
The 25 MWe version of the IMSR is the size of a fairly deep hottub

Nuclear Is NOT a Low-Carbon Source of Energy | Decentralizing energy production, increasing efficiency & increasing energy conservation are the real solutions for the environment.
Washington's Blog: Why Do People Claim that Nuclear Power is a Low-Carbon Source of Energy?
Even well-known, well-intentioned scientists sometimes push bad ideas. For example, well-known scientists considered pouring soot over the Arctic in the 1970s to help melt the ice – in order to prevent another ice age. That would have been stupid. Even Obama's top science adviser – John Holdren –warned in the 1970′s of a new ice age … and is open to shooting soot into the upper atmosphere. That might be equally stupid.
In other words, scientists – even prominent ones – sometimes fall prey to hairball theories and dangerous proposals. (Remember, doctors used to bleed patients to remove the "bad humors".)
Similarly, some scientists are under the mistaken impression that nuclear power is virtually carbon-free, and thus must be pushed to prevent runaway global warming. (If you don't believe in global warming, then this essay is not aimed at you … although you might wish to forward it to those who do.)
But this is a myth.
Amory Lovins is perhaps America's top expert on energy, and a dedicated environmentalist for close to 50 years. His credentials as an energy expert and environmentalist are sterling.
Lovins is a former Oxford don, who taught at nine universities, most recently Stanford. He has briefed 19 heads of state, provided expert testimony in eight countries, and published 31 books and several hundred papers. Lovins' clients have included the Pentagon, OECD, UN, Resources for the Future, many national governments, and 13 US states, as well as many Fortune 500 companies, major real-estate developers, and utilities. Lovins served in 1980-81 on the U.S. Department of Energy's Energy Research Advisory Board, and in 1999-2001 and 2006-08 on Defense Science Board task forces on military energy efficiency and strategy.
Lovins says nuclear is not the answer:
Nuclear plants are so slow and costly to build that they reduce and retard climate protection.
Here's how. Each dollar spent on a new reactor buys about 2-10 times less carbon savings, 20-40 times slower, than spending that dollar on the cheaper, faster, safer solutions that make nuclear power unnecessary and uneconomic: efficient use of electricity, making heat and power together in factories or buildings ("cogeneration"), and renewable energy. The last two made 18% of the world's 2009 electricity, nuclear 13%, reversing their 2000 shares–and made over 90% of the world's additional electricity in 2008.
Those smarter choices are sweeping the global energy market. Half the world's new generating capacity in 2008 and 2009 was renewable. In 2010, renewables except big hydro dams won $151 billion of private investment and added over 50 billion watts (70% the total capacity of all 23 Fukushima-style U.S. reactors) while nuclear got zero private investment and kept losing capacity. Supposedly unreliable windpower made 43-52% of four German states' total 2010 electricity. Non-nuclear Denmark, 21% wind-powered, plans to get entirely off fossil fuels. Hawai'i plans 70% renewables by 2025.
In contrast, of the 66 nuclear units worldwide officially listed as "under construction" at the end of 2010, 12 had been so listed for over 20 years, 45 had no official startup date, half were late, all 66 were in centrally planned power systems–50 of those in just four (China, India, Russia, South Korea)–and zero were free-market purchases. Since 2007,nuclear growth has added less annual output than just the costliest renewable–solar power –and will probably never catch up. While inherently safe renewable competitors are walloping both nuclear and coal plants in the marketplace and keep getting dramatically cheaper, nuclear costs keep soaring, and with greater safety precautions would go even higher. Tokyo Electric Co., just recovering from $10-20 billion in 2007 earthquake costs at its other big nuclear complex, now faces an even more ruinous Fukushima bill.
Since 2005, new U.S. reactors (if any) have been 100+% subsidized–yet they couldn't raise a cent of private capital, because they have no business case. They cost 2-3 times as much as new windpower, and by the time you could build a reactor, it couldn't even beat solar power. Competitive renewables, cogeneration, and efficient use can displace all U.S. coal power more than 23 times over–leaving ample room to replace nuclear power's half-as-big-as-coal contribution too–but we need to do it just once.
(Read Lovins' technical papers on the issue here.)
Alternet points out:
Mark Cooper, senior fellow for economic analysis at the Vermont Law School … found that the states that invested heavily in nuclear power had worse track records on efficiency and developing renewables than those that did not have large nuclear programs. In other words, investing in nuclear technology crowded out developing clean energy.
BBC notes:
Building the [nuclear] power station produces a lot of CO2 ….
Greenpeace points out:
When it comes to nuclear power, the industry wants you to think of electricity generation in isolation ….. And yet the production of nuclear fuel is a hugely intensive process. Uranium must be mined, milled, converted, enriched, converted again and then manufactured into fuel. You'll notice the [the nuclear industry] doesn't mention the carbon footprint of all steps in the nuclear chain prior to electricity generation. Fossil fuels have to be used and that means CO2 emissions.
An International Forum on Globalization report – written by environmental luminaries Ernest Callenback, Gar Smith and Jerry Mander – have slammed nuclear power as catastrophic for the environment:
Nuclear energy is not the "clean" energy its backers proclaim. For more than 50 years, nuclear energy has been quietly polluting our air, land, water and bodies—while alsocontributing to Global Warming through the CO2 emissions from its construction, mining, and manufacturing operations. Every aspect of the nuclear fuel cycle—mining, milling, shipping, processing, power generation, waste disposal and storage—releases greenhouse gases, radioactive particles and toxic materials that poison the air, water and land. Nuclear power plants routinely expel low-level radionuclides into the air in the course of daily operations. While exposure to high levels of radiation can kill within a matter of days or weeks, exposure to low levels on a prolonged basis can damage bones and tissue and result in genetic damage, crippling long-term injuries, disease and death.
See this excellent photographic depiction of the huge amounts of fossil fuel which goes into building and operating a nuclear power plant.
Nature reported in 2008:
"You're better off pursuing renewables like wind and solar if you want to get more bang for your buck."
***
Evaluating the total carbon output of the nuclear industry involves calculating those emissions and dividing them by the electricity produced over the entire lifetime of the plant. Benjamin K. Sovacool, a research fellow at the National University of Singapore, recently analyzed more than one hundred lifecycle studies of nuclear plants around the world, his results published in August in Energy Policy. From the 19 most reliable assessments, Sovacool found that estimates of total lifecycle carbon emissions ranged from 1.4 grammes of carbon dioxide equivalent per kilowatt-hour (gCO2e/kWh) of electricity produced up to 288 gCO2e/kWh. Sovacool believes the mean of 66 gCO2e/kWh to be a reasonable approximation.
The large variation in emissions estimated from the collection of studies arises from the different methodologies used – those on the low end, says Sovacool, tended to leave parts of the lifecycle out of their analyses, while those on the high end often made unrealistic assumptions about the amount of energy used in some parts of the lifecycle. The largest source of carbon emissions, accounting for 38 per cent of the average total, is the "frontend" of the fuel cycle, which includes mining and milling uranium ore, and the relatively energy-intensive conversion and enrichment process, which boosts the level of uranium-235 in the fuel to useable levels. Construction (12 per cent), operation (17 per cent largely because of backup generators using fossil fuels during downtime), fuel processing and waste disposal (14 per cent) and decommissioning (18 per cent) make up the total mean emissions.
According to Sovacool's analysis, nuclear power, at 66 gCO2e/kWh emissions is well below scrubbed coal-fired plants, which emit 960 gCO2e/kWh, and natural gas-fired plants, at 443 gCO2e/kWh. However, nuclear emits twice as much carbon as solar photovoltaic, at 32 gCO2e/kWh, and six times as much as onshore wind farms, at 10 gCO2e/kWh. "A number in the 60s puts it well below natural gas, oil, coal and even clean-coal technologies. On the other hand, things like energy efficiency, and some of the cheaper renewables are a factor of six better. So for every dollar you spend on nuclear, you could have saved five or six times as much carbon with efficiency, or wind farms," Sovacool says. Add to that the high costs and long lead times for building a nuclear plant about $3 billion for a 1,000 megawatt plant, with planning, licensing and construction times of about 10 years and nuclear power is even less appealing.
***
Money spent on energy efficiency, however, is equivalent to increasing baseload power, since it reduces the overall power that needs to be generated, says Sovacool. And innovative energy-storage solutions, such as compressed air storage, could provide ways for renewables to provide baseload power.
Thomas Cochran, a nuclear physicist and senior scientist at the Natural Resources Defense Council (NRDC), an environmental group in Washington DC … argues that the expense and risk of building nuclear plants makes them uneconomic without large government subsidies, and that similar investment in wind and solar photovoltaic power would pay off sooner.
***
Another question has to do with the sustainability of the uranium supply itself.According to researchers in Australia at Monash University, Melbourne, and the University of New South Wales, Sydney, good-quality uranium ore is hard to come by. The deposits of rich ores with the highest uranium content are depleting leaving only lower-quality deposits to be exploited. As ore quality degrades, more energy is required to mine and mill it, and greenhouse gas emissions rise. "It is clear that there is a strong sensitivity of … greenhouse gas emissions to ore grade, and that ore grades are likely to continue to decline gradually in the medium- to long-term," conclude the researchers. [And see this.]
Beyond Nuclear notes:
The energy consulting firm Ecofys produced a report detailing how we can meet nearly 100% of global energy needs with renewable sources by 2050. Approximately half of the goal is met through increased energy efficiency to first reduce energy demands, and the other half is achieved by switching to renewable energy sources for electricity production. The Intergovernmental Panel on Climate Change agrees and predicts close to 80% of the world's energy supply could be met by renewables by mid‐century.

Since nuclear power plants are reliant upon the electrical grid for 100% of their safety systems' long‐term power, and are shut down during grid failure and perturbations, it is "guaranteed" only as long as the electrical grid is reliable. When the Tsunami and earthquake hit and power was lost in the Fukushima Prefecture, nuclear energy wasn't so "guaranteed." Instead, it became a liability, adding to what was now a triple threat to the region and worsening an already catastrophic situation.

[The claim that] Nuclear power is "low‐carbon electricity" … is the propaganda line commonly used by the nuclear industry which conveniently leaves out every phase of the nuclear fuel chain other than electricity generation. It ignores the significant carbon emissions caused by uranium mining, milling, processing and enrichment; the transport of fuel; the construction of nuclear plants; and the still inadequate permanent management of waste. It also ignores the release ‐ by nuclear power plants and reprocessing facilities ‐ of radioactive carbon dioxide, or carbon‐14, to the air, considered to be the most toxic of all radioactive isotopes over the long‐term.
In fact, studies show that extending the operating licenses of old nuclear power plants emits orders of magnitude more carbon and greenhouse gases per kilowatt hour from just the uranium fuel chain compared to building and operating new wind farms.

Nuclear might begin to address global carbon emissions if a reactor is built somewhere in the world every two weeks. But this is an economically unrealistic, in fact impossible, proposition, with the estimated construction tab beginning at $12 billion apiece and current new reactors under construction already falling years behind schedule.
According to a 2003 MIT study, "The Future of Nuclear Power," such an unprecedented industrial ramping up would also mean opening a new Yucca Mountain‐size nuclear waste dump somewhere in the world "every three to four years," a task still unaccomplished even once in the 70 years of the industry's existence. Further, such a massive scale expansion of nuclear energy would fuel proliferation risks and multiply anxieties about nuclear weapons development, exemplified by the current concern over Iran. As Al Gore stated while Vice President: "For eight years in the White House, every weapons-proliferation problem we dealt with was connected to a civilian reactor program."
Many experts also say that the "energy return on investment" from nuclear power is lower than many other forms of energy. In other words, non-nuclear energy sources produce more energy for a given input.
David Swanson summarizes one of the key findings of the International Forum on Globalization report:
The energy put into mining, processing, and shipping uranium, plant construction, operation, and decommissioning is roughly equal to the energy a nuclear plant can produce in its lifetime. In other words, nuclear energy does not add any net energy.
Not counted in that calculation is the energy needed to store nuclear waste for hundreds of thousands of years.
Also not counted is any mitigation of the relatively routine damage done to the environment, including human health, at each stage of the process.

Nuclear energy is not an alternative to energies that increase global warming, because nuclear increases global warming. When high-grade uranium runs out, nuclear will be worse for CO2 emissions than burning fossil fuels. And as global warming advances, nuclear becomes even less efficient as reactors must shut down to avoid overheating.
Also not counted in most discussions is the fact that nuclear reactors discharge tremendous amounts of heat directly into the environment. After all – as any nuclear engineer will tell you – a nuclear reactor is really just a fancy way to boil water.
The Bulletin of the Atomic Scientists noted in 1971:
In terms of thermal efficiency, current nuclear reactors are even worse off than the coal plants. Against the 50 per cent loss of heat in the newest coal plants, as much as 70 per cent of the heat is lost from nuclear plants. This means that thermal pollution can be even more severe ….
1971 was a long time ago, but some nuclear plants are older. For example, Oyster Creek was launched in1969, and many other reactors were built in the early 1970s. Most American nuclear reactors are old (and they are aging very poorly).
Indeed, the Nuclear Information and Resource Service claims:
It has been estimated that every nuclear reactor daily releases thermal energy –heat– that is in excess of the heat released by the detonation of a 15 kiloton nuclear bomb blast.
It doesn't make too much sense to dump massive amounts of heat into the environment … in the name of fighting global warming.
The German Example
Germany permanently shut down 8 nuclear power plants in 2011. Indeed, Germany's phase-out of nuclear will speed up the reduction in its carbon footprint.
PhysOrg reported last year:
A special issue of the Bulletin of the Atomic Scientists, published by SAGE, "The German Nuclear Exit," shows that the nuclear shutdown and an accompanying move toward renewable energy are already yielding measurable economic and environmental benefits, with one top expert calling the German phase-out a probable game-changer for the nuclear industry worldwide.

Freie Universität Berlin politics professor Miranda Schreurs says the nuclear phase-out and accompanying shift to renewable energy have brought financial benefits to farmers, investors, and small business;
Felix Matthes of the Institute for Applied Ecology in Berlin concludes the phase-out will have only small and temporary effects on electricity prices and the German economy;
***
Lutz Mez, co-founder of Freie UniversitÓ“t Berlin's Environmental Policy Research Center, presents what may be the most startling finding of all …. "It has actually decoupled energy from economic growth, with the country's energy supply and carbon-dioxide emissions dropping from 1990 to 2011, even as its gross domestic product rose by 36 percent."
Beyond Nuclear notes:
Germany reduced its carbon emissions in 2011 by 2.1 percent despite the nuclear phaseout. The cut in greenhouse gases was mainly reached due to an accelerated transition to renewable energies and a warm winter. In addition, the EU emissions trading system caps all emissions from the power sector.
While eight nuclear power plants were shut down, solar power output increased by 60 percent. By the end of 2011, renewable energies provided more than 20 percent of overall electricity.
***
Even after shutting its eight oldest nuclear power plants, Germany is still a net exporter of electricity. In 2011, Germany exported 6 TWh more than it imported. Additionally, German electricity exports to Europe's nuclear power house France increased throughout 2011.
The Big Picture
The former chief American nuclear regulator says that nuclear energy is unsafe and should be phased out. Whistleblowers at the Nuclear Regulator Commission say that the risk of a major meltdown at U.S. nuclear reactors is much higher than it was at Fukushima.
And an accident in the U.S. could be a lot larger than in Japan … partly because our nuclear plants hold alot more radioactive material. Radiation could cause illness in huge numbers of Americans, and a major nuclear accident could literally bankrupt America.
More than 75 percent of American nuclear reactors leak radiation … and – contrary to what the snake oil salesmen say – radiation form nuclear plants is very damaging to our health.
Nuclear is wholly subsidized by the government … and would never survive in a free market.
Anyone who says the only choices are nuclear, oil or coal are wrong. The question isn't one type of centralized energy generation versus another.
Decentralizing energy production, increasing efficiency, and increasing energy conservation are the real solutions for the environment.
