Why the Fukushima disaster is worse than Chernobyl [29Aug11][ - 0 views

  • This nation has recovered from worse natural – and manmade – catastrophes. But it is the triple meltdown and its aftermath at the Fukushima nuclear power plant 40km down the coast from Soma that has elevated Japan into unknown, and unknowable, terrain. Across the northeast, millions of people are living with its consequences and searching for a consensus on a safe radiation level that does not exist. Experts give bewilderingly different assessments of its dangers.
  • Some scientists say Fukushima is worse than the 1986 Chernobyl accident, with which it shares a maximum level-7 rating on the sliding scale of nuclear disasters. One of the most prominent of them is Dr Helen Caldicott, an Australian physician and long time anti-nuclear activist who warns of "horrors to come" in Fukushima.
  • Chris Busby, a professor at the University of Ulster known for his alarmist views, generated controversy during a Japan visit last month when he said the disaster would result in more than 1 million deaths. "Fukushima is still boiling its radionuclides all over Japan," he said. "Chernobyl went up in one go. So Fukushima is worse."

  • On the other side of the nuclear fence are the industry friendly scientists who insist that the crisis is under control and radiation levels are mostly safe. "I believe the government and Tokyo Electric Power [Tepco, the plant's operator] are doing their best," said Naoto Sekimura, vice-dean of the Graduate School of Engineering at the University of Tokyo. Mr Sekimura initially advised residents near the plant that a radioactive disaster was "unlikely" and that they should stay "calm", an assessment he has since had to reverse.
  • Slowly, steadily, and often well behind the curve, the government has worsened its prognosis of the disaster. Last Friday, scientists affiliated with the Nuclear and Industrial Safety Agency said the plant had released 15,000 terabecquerels of cancer-causing Cesium, equivalent to about 168 times the 1945 atomic bombing of Hiroshima, the event that ushered in the nuclear age. (Professor Busby says the release is at least 72,000 times worse than Hiroshima).
  • Caught in a blizzard of often conflicting information, many Japanese instinctively grope for the beacons they know. Mr Ichida and his colleagues say they no longer trust the nuclear industry or the officials who assured them the Fukushima plant was safe. But they have faith in government radiation testing and believe they will soon be allowed back to sea.
  • That's a mistake, say sceptics, who note a consistent pattern of official lying, foot-dragging and concealment. Last week, officials finally admitted something long argued by its critics: that thousands of people with homes near the crippled nuclear plant may not be able to return for a generation or more. "We can't rule out the possibility that there will be some areas where it will be hard for residents to return to their homes for a long time," said Yukio Edano, the government's top government spokesman.
  • hundreds of former residents from Futaba and Okuma, the towns nearest the plant, were allowed to visit their homes – perhaps for the last time – to pick up belongings. Wearing masks and radiation suits, they drove through the 20km contaminated zone around the plant, where hundreds of animals have died and rotted in the sun, to find kitchens and living rooms partly reclaimed by nature.
  • It is the fate of people outside the evacuation zones, however, that causes the most bitter controversy. Parents in Fukushima City, 63km from the plant, have banded together to demand that the government do more to protect about 100,000 children. Schools have banned soccer and other outdoor sports. Windows are kept closed. "We've just been left to fend for ourselves," says Machiko Sato, a grandmother who lives in the city. "It makes me so angry."
  • Many parents have already sent their children to live with relatives or friends hundreds of kilometres away. Some want the government to evacuate the entire two million population of Fukushima Prefecture. "They're demanding the right to be able to evacuate," says anti-nuclear activist Aileen Mioko Smith, who works with the parents. "In other words, if they evacuate they want the government to support them."
  • Aid Fukushima: The UN's Office for the Co-ordination of Humanitarian Affairs reported bilateral aid worth $95m Chernobyl: 12 years after the disaster, the then Ukrainian president, Leonid Kuchma, complained that his country was still waiting for international help.
  • But many experts warn that the crisis is just beginning. Professor Tim Mousseau, a biological scientist who has spent more than a decade researching the genetic impact of radiation around Chernobyl, says he worries that many people in Fukushima are "burying their heads in the sand." His Chernobyl research concluded that biodiversity and the numbers of insects and spiders had shrunk inside the irradiated zone, and the bird population showed evidence of genetic defects, including smaller brain sizes.
  • "The truth is that we don't have sufficient data to provide accurate information on the long-term impact," he says. "What we can say, though, is that there are very likely to be very significant long-term health impact from prolonged exposure."
  • Economic cost Fukushima: Japan has estimated it will cost as much as £188bn to rebuild following the earthquake, tsunami and nuclear crisis. Chernobyl There are a number of estimates of the economic impact, but thetotal cost is thought to be about £144bn.
  • Safety Fukushima: workers are allowed to operate in the crippled plant up to a dose of 250mSv (millisieverts). Chernobyl: People exposed to 350mSv were relocated. In most countries the maximum annual dosage for a worker is 20mSv. The allowed dose for someone living close to a nuclear plant is 1mSv a year.
  • Death toll Fukushima: Two workers died inside the plant. Some scientists predict that one million lives will be lost to cancer. Chernobyl: It is difficult to say how many people died on the day of the disaster because of state security, but Greenpeace estimates that 200,000 have died from radiation-linked cancers in the 25 years since the accident.
  • Exclusion zone Fukushima: Tokyo initially ordered a 20km radius exclusion zone around the plant Chernobyl: The initial radius of the Chernobyl zone was set at 30km – 25 years later it is still largely in place.
  • Compensation Fukushima: Tepco's share price has collapsed since the disaster largely because of the amount it will need to pay out, about £10,000 a person Chernobyl: Not a lot. It has been reported that Armenian victims of the disaster were offered about £6 each in 1986
  • So far, at least, the authorities say that is not necessary. The official line is that the accident at the plant is winding down and radiation levels outside of the exclusion zone and designated "hot spots" are safe.
  • Japan has been slow to admit the scale of the meltdown. But now the truth is coming out. David McNeill reports from Soma City

Nuclear Power is Not Dead--Not By a Long Shot [13Apr11] - 0 views

  • Obviously, the last thing the nuclear power industry needed was another black eye. Yet even with ongoing disaster in Japan, the nuclear power revival is one that cannot be stopped — even by the combined power of an earthquake and a tsunami. Outside of the dramatic news coverage, the atomic beat goes on. Here's why... As desirable as it is to develop a safer alternative, nuclear power is still one of the bedrocks of the power generation that fuels the world economy.
  • All told, 442 nuclear power plants across the globe provide roughly 14% of its electricity generation. That figure is going to be impossible to finesse or eliminate... even under the best-case scenarios for the development of wind, solar power, and/or other forms of alternative energy. According to the International Energy Association (IEA), world electricity demand is likely to grow 2.7 percent a year from now until 2015, and then at 2.4 percent annually until 2030 — making nuclear power even more of a necessary evil.
  • Nuclear Revival Lives The result: The nuclear industry is experiencing a major global power surge. Worldwide, 65 reactors are already under construction with 344 more reactors planned. Add it all up and it makes for a 92% increase from today's levels for the global nuclear industry. Even through the lens of the Fukishima disaster, this trend will go on long after the current Japanese turmoil leaves the headlines

  • Why?
  • Because realistically, there is no other course
  • One of the design developments for investors to keep an eye on is in construction of what are known as small modular reactors (SMRs). This new school category of plants is defined as reactors making less than 300 megawatts of electricity, or the amount needed to power 300,000 American homes. (That's about a quarter of the energy output of today's big reactors.)
  • Factory-built and delivered on site, small modular reactors have the potential to change the nuclear landscape. In this case, it's as simple as time and money. Because unlike large reactors that cost as much as $10 billion and take five years to build, small modular reactors can be built in half the time and for as little as $5000 per kilowatt capacity. What's more, the modular units arrive on site ready to "plug and play", dramatically changing the old model of time and cost. But here's the real kicker: SMRs are designed for a high level of passive or inherent safety in the event of a malfunction.
  • according to a 2010 report by the American Nuclear Society, many of the prudent safety provisions already built in large reactors are unnecessary in the smaller designs. And their smaller size also allows them to be built underground, making them considerably less vulnerable to the events that caused the Fukishima disaster
  • “This is a reactor that is designed with safety first,” says Victor Reis, senior advisor in the Office of Undersecretary of Energy for Science, “not one that you do the physics first and then add the safety on.”
  • These smaller designs also have the support of the current administration, whose 2012 budget request provides $67 million to help companies develop smaller plants and win regulatory approval for their designs. Meanwhile, the Commerce Department recently called SMRs a “tremendous new commercial opportunity for U.S. firms and workers” since, according to the International Atomic Energy Agency, the global demand for small modular reactors could reach 500 to 1,000 reactors by 2040.
  • One of the early leaders in this new trend is a long-time nuclear player called Babcock and Wilcox (NYSE: BWC).

Why You Should Ignore Germany's Nuclear U-Turn [02Jun11] - 0 views

  • According to German Chancellor Angela Merkel, “We want the electricity of the future to be safe, reliable and economically viable.” And in her mind, nuclear power doesn’t fit the bill anymore. She’s wrong. The truth is, nuclear power is safe, reliable, clean and cheap. And that’s precisely why global nuclear capacity is going to keep increasing, by as much as 50% between now and 2020. It’s also the reason why the long-term investment thesis for uranium stocks remains compelling
  • Don’t Let Recent Events Mislead You As humans, we have a tendency toward recency bias. In other words, we give recent events extra importance when making decisions. The recent radiation crisis in Japan is an example.
  • believing that nuclear power is now suddenly unsafe is patently wrong. As the following chart shows, nuclear power is actually the safest form of energy production available. And if anything, the crisis at Japan’s 40-year-old Fukushima Daiichi plant is only going to increase the safety precautions at existing and new nuclear power plants
  • ...4 more annotations...
  • Not only is nuclear power safest, it also happens to be extremely clean. Nuclear power generation produces virtually no greenhouse gases. It’s one of the most economical energy sources, too. It only costs about $0.04 per kilowatt hour (kWh) to produce electricity with nuclear power, compared to $0.08 per kWh for wind and more than $0.18 per kWh for solar.
  • While Germany Pulls a U-ey, Follow China, India and America Instead While Germany’s nuclear decision has made headlines this week, the positive future for nuclear power was underlined a few weeks ago when two of the fastest-growing global economies gave the industry a big shot in the arm. ~ China: On May 12, China’s Nuclear Energy Association announced plans to boost the country’s nuclear power capacity as much as eight times by 2020. ~ India: A day later, India’s Atomic Energy Commission announced plans to increase production 13-fold by 2020. And they’re not alone. Although the United States didn’t announce any specific growth plans, it’s certainly not abandoning nuclear power production.
  • In the aftermath of the Japan crisis, the U.S. Nuclear Regulatory Commission said it would scrutinize nuclear license renewals. But in April, the commission renewed the operating license for the largest nuclear power plant in the United States for another 20 years. And as Jeff Eerkens, an adjunct professor at the University of Missouri’s Nuclear Science and Energy Institute, estimates, the United States needs to quintuple its number of power plants to keep up with electricity demand.

U.S. Ready to Take More Oil Action If Needed, Official Says [23Jun11] - 0 views

  • The U.S., after authorizing the release of 30 million barrels of oil from its emergency stockpile, is prepared to take additional action if needed to react to disruptions in world supplies, according to an Obama administration official. The decision to draw oil from the Strategic Petroleum Reserve, part of an international move to release 60 million barrels, was made after months of consulting with allies and oil-producing nations, according to officials, who briefed reporters on condition they not be named.
  • The coordinated release of 60 million barrels by the U.S. and 27 other nations would provide about 2 million barrels a day within the first 30 days, according to the IEA.
  • Supply Concerns The release is being done in response to disruption caused by the Libya conflict and in anticipation of increasing demand during the U.S. summer driving season, the official said. It is intended more to ensure supply rather than affect prices, according to the official. The national average retail price for a gallon of regular gasoline is $3.612, according to a AAA survey.

Energy Demand Will Push Development of Nuclear Power - WSJ.com [24Oct11] - 0 views

  • It has been two years since Mohamed ElBaradei stepped down as head of the United Nations' nuclear watchdog, but the Nobel peace laureate still has nuclear technology very much on his mind.
  • But Mr. ElBaradei doesn't subscribe to the widely held view that Fukushima has killed off the nuclear industry for the foreseeable future. In fact, he argues countries exiting nuclear-power generation are the exception rather than the rule. "There will be, in the short term, a slowdown in some countries. But others like France, India or China [won't see] an impact on their [nuclear] programs," he says.
  • He also points to some nuclear newcomers, such as the United Arab Emirates and Turkey.

  • Further development of nuclear power is guaranteed by the exponential global growth in energy demand, he says, pointing to a study by the U.S. Energy Information Administration estimating global electricity-generation growth of 87% by 2035 as the world's population grows.
  • But while he argues the planet has to live with nuclear energy he acknowledges this has a risk. "Nuclear energy as with any technology has always a risk. You have to balance the costs and benefits," he says.
  • "People need to take safety much more seriously than in the past. I've suggested a number of things that need to be done: a mandatory peer review by experts on every facility, an overall review of all nuclear plants both civilian and military."
  • "People are hypersensitive to anything nuclear, to radioactivity. You don't know how it will impact you. The nuclear industry has to take that into account. They have to go out of their way to make sure that it is as safe as possible. We have to design nuclear-power reactors not just for the worst-case scenario but for the seemingly impossible," he says.

Japan winter power enough despite nuclear lack: government | Reuters - 0 views

  • (Reuters) - Japanese utilities will largely avoid power shortages this winter despite prolonged reactor shutdowns amid public concerns over nuclear safety, but hurdles remain for next summer, the government said on Tuesday.
  • It also unveiled ways to bridge the gap next summer, when peak-hour demand is expected to exceed supply by 16,560 megawatts, compared with the biggest gap this winter of 2,530 MW in one area, if no reactors restart by then.
  • Utilities plan to secure additional fossil-fuel capacity of 4,090 MW by next summer, but other plans depend on how far policy initiatives, such as fiscal spending, can encourage energy conservation and the use of solar and wind power, leaving the risk of rolling blackouts.
  • ...3 more annotations...
  • Using gas and oil to make up for the loss of all nuclear power reactors will cost more than 3 trillion yen ($38 billion) a year, based on imported fuel prices and utilization rates in 2009, the government has estimated.
  • "Even if no reactors are restarted by next summer, the government would like to do its utmost through policy efforts to ensure we can meet peak-hour demand and avoid a rise in costs for energy," Trade Minister Yukio Edano said at a news conference after he and other ministers discussed chances of power shortages this winter and next summer.
  • The ongoing radiation crisis at Tokyo Electric Power Co's Fukushima Daiichi plant, triggered by the March earthquake and tsunami, has shaken public confidence in nuclear safety, forcing watchdogs to set stricter regulations for restarting reactors closed for regular checks.

Uranium Deals Prove Most Lucrative as Nuclear Demand Increases: Real M&A [25Oct11] - 0 views

  • Uranium takeovers are offering investors the biggest potential payoffs, less than a year after the partial meltdown of Japan’s Fukushima nuclear plant. Hathor Exploration Ltd. (HAT), the owner of a uranium deposit in northern Saskatchewan, yesterday traded 8.4 percent above a bid from Rio Tinto Group that topped an offer from Cameco Corp. (CCO) That signals investors are now betting Hathor will extract the biggest price hike of any pending North American deal greater than $500 million, according to data compiled by Bloomberg. Kalahari Minerals Plc (KAH), which resumed talks with China Guangdong Nuclear Power Group after a takeover was derailed by Japan’s disaster, would now hand shareholders a higher return than the pre-Fukushima agreement, even with a 5 percent lower offer.
  • Hathor slipped 0.2 percent to C$4.49 in Toronto today, while Cameco fell 0.2 percent to C$20.88. Rio Tinto retreated 2.1 percent to 3,302.5 pence in London. Cameco, the world’s biggest uranium producer, took its takeover offer for Hathor directly to shareholders after the companies couldn’t agree on a price. The proposal would give Hathor’s shareholders C$3.75 a share in cash, valuing the uranium explorer at C$520 million ($530 million), according to the Aug. 26 statement.
  • After investors pushed the stock as much as 12 percent above Cameco’s offer, Rio Tinto, the world’s second-largest mining company, trumped the proposal last week. Rio Tinto’s bid valued Hathor at C$4.15 a share in cash, or C$578 million, according to the Oct. 19 statement.

Japanese government still refusing to evacuate Fukushima children [30Oct11] - 0 views

  • On the 27th of October 2011, Fukushima women met government officials in Tokyo to demand that the government evacuate Fukushima children immediately. But, the government official only repeated the government’s policy of cleaning up the contaminated area in Fukushima. On the 27th of October 2011, hundreds of Fukushima women gathered in front of the governmental building (Ministry of Economy, Trade and Industry) in Tokyo to protest against nuclear power plants. Among them, thirty Fukushima women met government officials. They handed a written request asking for the abolition of all nuclear power plants and the evacuation of Fukushima children, and demanded the government answer to it in writing by 11th of November.

Fracking floors energy giants - Business Analysis & Features - Business - The Independent - 0 views

  • A fortnight after writing $2.84bn (£1.84bn) off the value of its Fayetteville shale gas business in Arkansas, BHP is poised to reveal on Wednesday that the charge helped push down its profits by a massive 40 per cent – to $14.2bn – in the year to June 30.

  • US gas price fell from $3.88 per thousand cubic feet when the deal was struck to as little as $1.91 in April, before recovering slightly to now hover around $2.75. Today's mildly-improved US gas price is well below its peak of $14 per thousand cubic feet in 2005
  • hile protests in the US have largely failed to curb the shale gas industry's development, the plummeting gas price is now doing the job for them. The number of shale gas rigs operating in the US has tumbled by 44 per cent in the past year to stand at about 300 now, according to industry estimates.
  • Hydrocarbon producers such as Chesapeake and BHP are furiously switching their fracking resources from gas to oil, which is unlikely to suffer the same depression in its price as gas as the US has the infrastructure in place to export much of the additional oil it produces from shale. As a result, the number of shale oil rigs has leapt by 35 per cent to about 860 in the past year.

Tepco officially admitted they don't need nuclear power [22Nov11] - 0 views

  • 11/22/2011, it turned out that Tepco estimated that they can cover all the electric consumption even without nuclear plants. By using pumped-storage power generation and steam-power generation ,next summer they can supply more than 57 million kilowatts, which is the maximum supply capacity of this summer. This year, we did not run out of power. 57 million kilowatts is even OVER supply. The annual peak of the electric consumption is late August in Japan. By proving that they can cover the potential demand of next summer, it has become clear that they don’t need nuclear power through a year. There are 54 nuclear plants in Japan. Tepco owns 17 of them.

Post-Fukushima, Nuclear Power Changes Latitudes - [28Nov11] - 0 views

  • As the full cost of the Fukushima nuclear accident continues to climb—Japanese officials now peg it at $64 billion or more—nuclear power’s future is literally headed south. Developed countries are slowing or shuttering their nuclear-power programs, while states to their south, in the world’s hotspots (think the Middle East and Far East), are pushing to build reactors of their own. Normally, this would lead to even more of a focus on nuclear safety and nonproliferation. Yet, given how nuclear-reactor sales have imploded in the world’s advanced economies, both these points have been trumped by nuclear supplier states’ desires to corner what reactor markets remain.
  • This spring, Germany permanently shut down eight of its reactors and pledged to shutter the rest by 2022. Shortly thereafter, the Italians voted overwhelmingly to keep their country nonnuclear. Switzerland and Spain followed suit, banning the construction of any new reactors. Then Japan’s prime minister killed his country’s plans to expand its reactor fleet, pledging to reduce Japan’s reliance on nuclear power dramatically. Taiwan’s president did the same. Now Mexico is sidelining construction of 10 reactors in favor of developing natural-gas-fired plants, and Belgium is toying with phasing its nuclear plants out, perhaps as early as 2015.
  • China—nuclear power’s largest prospective market—suspended approvals of new reactor construction while conducting a lengthy nuclear-safety review. Chinese nuclear-capacity projections for the year 2020 subsequently tumbled by as much as 30 percent. A key bottleneck is the lack of trained nuclear technicians: to support China’s stated nuclear-capacity objectives, Beijing needs to graduate 6,000 nuclear experts a year. Instead, its schools are barely generating 600.

  • India, another potential nuclear boom market, is discovering a different set of headaches: effective local opposition, growing national wariness about foreign nuclear reactors, and a nuclear liability controversy that threatens to prevent new reactor imports. India was supposed to bring the first of two Russian-designed reactors online this year in tsunami-prone Tamil Nadu state. Following Fukushima, though, local residents staged a series of starvation strikes, and the plant’s opening has now been delayed. More negative antinuclear reactions in the nearby state of West Bengal forced the local government to pull the plug on a major Russian project in Haripur. It’s now blocking an even larger French reactor-construction effort at Jaitapur.
  • These nuclear setbacks come as Prime Minister Manmohan Singh is straining to reconcile India’s national nuclear-accident-liability legislation with U.S. demands that foreign reactor vendors be absolved of any responsibility for harm that might come to property or people outside of a reactor site after an accident
  • n the United States, new-reactor construction has also suffered—not because of public opposition but because of economics
  • persuade his Parliament to cap foreign vendors’ liability to no more than $300 million (even though Japan has pegged Fukushima damages at no less than $64 billion).
  • The bottom line is that in 2007, U.S. utilities applied to the Nuclear Regulatory Commission to build 28 nuclear-power plants before 2020; now, if more than three come online before the end of the decade, it will be a major accomplishment.
  • France—per capita, the world’s most nuclear-powered state. Frequently heralded as a nuclear commercial model for the world, today it’s locked in a national debate over a partial nuclear phaseout.
  • his Socialist opponent, François Hollande, now well ahead in the polls, has proposed cutting nuclear power’s contribution to the electrical grid by more than a third by 2025. Hollande is following a clear shift in French public opinion, from two thirds who backed nuclear power before Fukushima to 62 percent who are now favoring a progressive phaseout. In addition, the French courts just awarded Greenpeace €1.5 million against the French nuclear giant EDF for illegally spying on the group. Public support of this judgment and the French Socialist Party’s wooing of the French Greens makes the likelihood of Hollande backing off his pledge minuscule.

AM - Fukushima secrecy over workers and conditions[ 07Dec11] - 0 views

  • TONY EASTLEY: Still in Japan and the ABC has obtained documents revealing the lengths being taken to keep work at the crippled Fukushima nuclear plant secret and to stop workers there from actually talking to the media.One former worker at the plant has told the ABC how they were given sub-standard protective gear after the accidents.North Asia correspondent Mark Willacy reports from Iwaki City in Fukushima.MARK WILLACY: Inside the leeching and twisted remains of the Fukushima nuclear plant 3000 workers are labouring to stabilise the melted reactor cores.It's dirty and dangerous work, and some workers claim they're being exposed and exploited.
  • : "I was not told how much radiation I would be exposed to or how high the radiation would be," says this man who worked at the Fukushima plant during the meltdowns. "They just gave me an anorak to wear and sent me to work. I worked at installing vents inside the reactor buildings to get rid of the steam so we could avert another explosion," he tells me.There's a good reason why this Fukushima worker doesn't want his identity revealed and that's because like others, he's been gagged.The ABC has obtained a document drawn up by one of the Fukushima subcontractors. It demands that its employees at the plant keep all of their work secret and under no circumstances are they permitted to talk to the media.

  • "Right after the meltdowns some workers were not even given face masks with filters in them," says the Communist Party councillor from Iwaki, a city 45 kilometres from the nuclear plant. "Others had to share rubber boots. Some of the boots had holes in them that let in radioactive water in," he says.The operator of Fukushima,TEPCO, does admit that there was a shortage of gear at the plant but the situation has now improved, according to TEPCO spokesman Yoshikazu Nagai.
  • "The situation was chaotic in the early stages of the accident," he tells me. "There were cases where groups of workers had to share a Geiger counter. But now all workers have their own device, as well as suits. And all radiation exposure is measured and controlled," he says. But Iwaki City Councillor Hiroyuki Watanabe says the situation at Fukushima is still chaotic. He's collected dozens of files on safety breaches at the plant, as well as the alleged underpayment of workers.
  • "Subcontractors working for TEPCO have ripped off their employees," he tells me. "Some workers are paid as little as $80 a day," he says.The former Fukushima worker we spoke to confirmed this, saying he left because his subcontractor wages were much less than those paid to TEPCO employees.For its part, TEPCO pleads ignorance when it comes to what its subcontractors pay its employees.
  • "We do not know what kind of wages they're paid or the particular conditions they're working under," says TEPCO spokesman Yoshikazu Nagai.

Japan Times: Radiation problems will continue for a very long time - Complete disclosur... - 0 views

  • Organizers of the Global Conference for a Nuclear Power Free World [in Yokohama] claimed 6,000 participants from some 30 countries [...] The conference shows all the signs of turning into a coherent, focused movement. [...] The conference’s call for “full transparency, accountability and responsibility by the Japanese Government and Tokyo Electric Power Company” is just as important. Without complete disclosure, progress toward grasping the causes of the problem and finding solutions cannot gain traction. The conference’s calls for ongoing data collection about the safety of food and materials will also be close to the hearts of all consumers. Already, consumers have been demanding basic information about foodstuffs and potentially contaminated materials. Last week’s discovery that radioactive gravel in concrete used to build a new condominium in Nihonmatsu, Fukushima Prefecture, is one more reminder that problems will continue for a very long time. Nuclear issues have come to home to roost. [...] it is clear that a practical consensus towards a different energy future is well underway. Now that is a weekend well spent!

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

  • Tokyo Shinbun is a regional newspaper covering Kanto region of Japan. It has been reporting on the Fukushima accident and resultant radiation contamination in a more honest and comprehensive manner than any national newspaper. (Their only shortcoming is that their links don't seem to last for more than a week.)Their best coverage on the subject, though, is not available digitally but only in the printed version of the newspaper. But no worry, as there is always someone who transcribes the article and post it on the net for anyone to see.
  • In the 2nd half of the January 27 article, Tokyo Shinbun details what kind of workers are currently working at Fukushima I Nuclear Power Plant: migrant workers young (in their 20's) and not so young (in their 60's), untrained, $100 a day. Some of them cannot even read and write.
  • Right now, 70% of workers at the plant are migrant contract workers from all over Japan. Most of them have never worked at nuke plants before. The pay is 8000 yen to 13,000 yen [US$104 to $170] per day. Most of them are either in their 20s who are finding it difficult to land on any job, or in their 60s who have "graduated" from the previous jobs."

  • The relationship between the cause of Mr. Osumi's death and radiation exposure is unknown. However, it is still the radiation exposure that is most worrisome for the workers who work at Fukushima I Nuke Plant to wind down the accident. The radiation exposure limit was lowered back to the normal "maximum 50 millisieverts per year" and "100 millisieverts in 5 years" on December 16 last year. It was done on the declaration of "the end of the accident" by Prime Minister Noda that day.
  • The radiation exposure limit was raised to 250 millisieverts per year right after the accident, as a special measure. The Ministry of Health and Labor argued that the number was based on the international standard for a severe accident which was 500 millisieverts. But the real purpose was to increase the number of hours that can be put in by the workers and to increase the number of workers to promptly wind down the accident.
  • However, as the prime minister wanted to appeal "the end of the accident", the limit was lowered back to the normal limit.
  • According to TEPCO, the radiation exposure levels of workers exceeded [annualized?] 250 millisieverts in some cases right after the accident, but since April it has been within 100 millisieverts.
  • However, the workers voice concerns over the safety management. One of the subcontract workers told the newspaper:
  • He also says the safety management cannot be fully enforced by TEPCO alone, and demands the national government to step in. "They need to come up with the management system that include the subcontract workers. Unless they secure the [safe] work environment and work conditions, they cannot deal with the restoration work that may continue for a long while."
  • From Tokyo Shinbun (1/27/2012):(The first half of the article is asbout Mr. Osumi, the first worker to die in May last year after the plant "recovery" work started. About him and his Thai wife, please read my post from July 11, 2011.)
  • Then the workers start working at the site. But there are not enough radiation control personnel who measure radiation levels in the high-radiation locations, and warn and instruct the workers. There are too many workers because the nature of the work is to wind down the accident. There are workers who take off their masks or who smoke even in the dangerous [high radiation] locations. I'm worried for their internal radiation exposures."
  • In the rest area where the workers eat lunch and smoke, the radiation level is 12 microsieverts/hour. "Among workers, we don't talk about radiation levels. There's no point."
  • The worker divulged to us, "For now, they've managed to get workers from all over Japan. But there won't be enough workers by summer, all bosses at the employment agencies say so." Local construction companies also admit [to the scarcity of workers by summer.]
  • "Local contractors who have been involved in the work at Fukushima I Nuclear Power Plant do not work there any more. It's dangerous, and there are jobs other than at the nuke plant, such as construction of temporary housing. The professional migrant workers who hop from one nuclear plant to another all over Japan avoid Fukushima I Nuke Plant. The pay is not particularly good, so what is the point of getting high radiation to the max allowed and losing the opportunity to work in other nuclear plants? So, it's mostly amateurs who work at the plant right now. Sooner or later, the supply of workers will dry up."
  • As to the working conditions and wage levels of the subcontract workers, TEPCO's PR person explains, "We believe the subcontracting companies are providing appropriate guidance." As to securing the workers, he emphasizes that "there is no problem at this point in sourcing enough workers. We will secure necessary workers depending on how the work progresses."
  • However, Katsuyasu Iida, Director General of Tokyo Occupational Safety and Health Center who have been dealing with the health problems of nuclear workers, points out, "Workers are made to work in a dangerous environment. The wage levels are going down, and there are cases of non-payment. It is getting harder to secure the workers."
  • As to the safety management, he said, "Before you start working at a nuclear power plant, you have to go through the "training before entering radiation control area". But in reality the training is ceremonial. The assumptions in the textbook do not match the real job site in an emergency situation. There were some who could not read, but someone else filled in the test for them at the end of the training."
  • Memo from the desk [at Tokyo Shinbun]: Workers at Fukushima I Nuke Plant are risking their lives. Some are doing it for 8000 yen per day. A councilman who also happens to work for TEPCO earns more than 10 million yen [US$130,000] per year. Executives who "descended from heaven" to cushy jobs in the "nuclear energy village" are alive and well. To move away from nuclear power generation is not just about energy issues. It is to question whether we will continue to ignore such "absurdity".
  • Well said. Everybody in the nuclear industry in Japan knew that the industry depended (still does) on migrant workers who were (still are) hired on the cheap thorough layer after layer of subcontracting companies. Thanks to the Fukushima I Nuclear Plant accident, now the general public know that. But there are plenty of those who are still comfortable with the nuclear power generated by the nuclear power plants maintained at the expense of such workers and see nothing wrong with it.

LED Poised To Light Up The World: Study [20Jan12] - 0 views

  • In the next decade, LED lights will capture more than half of the world’s demand for new lighting, the author of a study on green economic opportunities said last night at a University of Chicago forum.
  • Robert Weissbourd, the president of RW-Ventures, was studying economic development in the Chicago region when he and other authors  of “The Chicago Region’s Green Economic Opportunities” (pdf) realized the potential of LED lighting.
  • “It’s projected that the shift to LED lighting is going to be huge. It’s going to capture 60 percent of the market globally in the next ten years.”
  • ...1 more annotation...
  • That shift will be motivated not only by a global response to climate change, but especially by the economic benefits of LED lights. “They’re clearly a superior product,” Weissbourd said, “but not yet market accepted.”

Wind farms can actually INCREASE climate change by raising temperatures, warn academics... - 0 views

  • Temperatures can fall by up to 4C downwind of farms
  • Tory MPs write to PM demanding dramatic subsidy cuts
  • The team from the University of Illinois found that daytime temperatures around wind farms can fall by as much as 4C, while at night temperatures can increase
  • ...3 more annotations...
  • The study found that currently the effect is restricted to areas near to the turbines, but the increase in larger farms could create weather changes on a regional scale.The study was led by Somnath Roy, assistant professor of atmospheric sciences at the university, with the San Gorgonio wind farm in California the focal point of his research.
  • He found that the day ground temperature behind turbines was up to 4C lower than in front. He suggested that the turbines' blades scoop warm from the ground and push the cooler air downwards. This is then reversed at night.
  • Roy, whose findings were published in the Sunday Times, added that he believes the turbines causing turbulence and reducing winds speed are the cause.He also added that the churning of air from low to high can create vortices that could extend the phenomenon for large distances downwind.

A Peek Inside the IAEA [09Oct11] - 0 views

  • This rather mundane looking letter from 2000 talks about a number of concerns going on with the IAEA at that time. One concern was the Bushehr nuclear plant in Iran. “Indications that Russia’s efforts to complete the Bushehr reactor in Iran are plagued with severe safety considerations as witnessed by periodic visits by IAEA experts. ” Recently a whistleblower told that the Bushehr plant was a safety disaster and that it was hobbled together with disparate parts by second string engineers. The US had concerns about the lack of safety assistance at the Mayak nuclear site in Russia. This is similar to the Hanford nuclear site in the US and houses large amounts of volatile nuclear waste. Mayak was the site of an INES level 6 disaster in 1957 that sent a plume of highly radioactive cesium 137 and stronium 90 over a populated area nearby.  This disaster happened due to loss of cooling on a waste tank.
  • The letter also talked about the financial constraint of needing to spend $3 million dollars to do mandated oversight at the Rokkasho Mura nuclear waste facility in Japan. It also spoke of a severe budget crisis by 2001 as countries were not putting more funding into the IAEA as the demands on the agency were increasing. The 2009 accounting of the IAEA’s budget.

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

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

Nuclear Engineer shares concerns about Brunswick Nuclear Leak [19Nov11] - 0 views

  • The US Nuclear Regulatory Commission will begin a special inspection at Progress Energy‘s Brunswick-2 unit in North Carolina after the utility said Friday the reactor pressure vessel’s lid was not adequately tightened when it restarted earlier this week.  Most of us are also paying close attention to the events at Brunswick Nuclear Power Plant, and today I talked with a former nuclear engineer  Chris Harris about the recent developments.
  • The unit shut Wednesday morning after the reactor leaked. An investigation showed the inadequately tightened reactor vessel head was a potentially “significant” safety issue, Progress said in a report filed Friday with the NRC. Workers seeking the source of the leak found that at least 10 of the 64 bolts that secure the reactor vessel head to the pressure vessel were not fully tightened, Progress spokesman Ryan Mosier said in an email Friday.
  • The unit had been in a maintenance outage, was in the process of restarting and was operating at 7% power when workers discovered the leak in the reactor coolant system, Progress said in an event report filed Wednesday with NRC. When the leak exceeded 10 gal/minute, the unit was shut, Progress said.

  • The Brunswick Nuclear Plant has two boiling-water reactors that generate 1,875 megawatts of electricity. Each of the Brunswick reactors is refueled once every 24 months, usually in the spring when the demand for electricity is relatively low. At the Brunswick Plant, 1 million gallons of water per minute are pumped from the Cape Fear River where it passes through the plant’s cooling system and then drops approximately  15 feet to the head of the outflow canal.
  • Refueling procedures are elaborate and well documented procedures, and one of the biggest questions is why the proper procedures were not followed, or were carried out incorrectly. The bolts need to be tensioned in a specific Torque Pattern, which generally includes multiple passes.  Refueling procedures require a crew of  at least 6 engineers, and additional Quality Control inspectors.
  • The Tensioning Tool is inspected and maintained, and is also part of the QC checklist.  This is not a simple situation where someone didn’t torque down the bolts correctly, as multiple personnel would have had to check and confirm the status prior to restart. In fact, according to Progress Energy’s 35 day outage schedule, the reassembly and reactor test are the 9th, and 10th steps of the process, and one can’t help but wonder why this was not detected before the reactor was re-pressurized. Chris had some very good questions regarding the Brunswick event, that I felt were worth sharing.
  • What testing was performed to determine that the RPV Head was Tensioned properly? What caused the improper Tensioning ? Procedure, Skill of the Craft? Aggressive Schedule? What are the Acceptance Criteria in the procedure for a properly tensioned head” How do you know that you meet the Acceptance Criteria?
  • Not only are the procedures and QC process in question, but the event also impacts operations and reliability of reactor components.  Chris highlighted a few questions that he felt were critical to ensure safe restart and operation.
  • Could there have been Foreign Material on the RPV Head Flange? What damage to surrounding equipment in the Drywell was sustained by the Steam/Water Leak? What is the condition of the Refueling Seal, now that it has been sprayed with Steamy/Hot Water? Did Hot/Steamy water find its way on the Outside of the Containment such that Corrosion in the future will be a problem? Did the steam leakage affect the Reactor Vessel Head Studs and their Threaded Holes (in the Reactor Vessel Flange) such that they will fail at a future date? At this point, Progress Energy is keeping fairly quiet about the specifics, and initially only revealed information of a “possible leak at the top of the reactor vessel”.  Monday morning should prove eventful not only for the Utility, but also for regulators.

The myth of renewable energy | Bulletin of the Atomic Scientists - 0 views

  • "Clean." "Green." What do those words mean? When President Obama talks about "clean energy," some people think of "clean coal" and low-carbon nuclear power, while others envision shiny solar panels and wind turbines. And when politicians tout "green jobs," they might just as easily be talking about employment at General Motors as at Greenpeace. "Clean" and "green" are wide open to interpretation and misappropriation; that's why they're so often mentioned in quotation marks. Not so for renewable energy, however.
  • people across the entire enviro-political spectrum seem to have reached a tacit, near-unanimous agreement about what renewable means: It's an energy category that includes solar, wind, water, biomass, and geothermal power.
  • Renewable energy sounds so much more natural and believable than a perpetual-motion machine, but there's one big problem: Unless you're planning to live without electricity and motorized transportation, you need more than just wind, water, sunlight, and plants for energy. You need raw materials, real estate, and other things that will run out one day. You need stuff that has to be mined, drilled, transported, and bulldozed -- not simply harvested or farmed. You need non-renewable resources:
  • ...15 more annotations...
  • Solar power. While sunlight is renewable -- for at least another four billion years -- photovoltaic panels are not. Nor is desert groundwater, used in steam turbines at some solar-thermal installations. Even after being redesigned to use air-cooled condensers that will reduce its water consumption by 90 percent, California's Blythe Solar Power Project, which will be the world's largest when it opens in 2013, will require an estimated 600 acre-feet of groundwater annually for washing mirrors, replenishing feedwater, and cooling auxiliary equipment.
  • Geothermal power. These projects also depend on groundwater -- replenished by rain, yes, but not as quickly as it boils off in turbines. At the world's largest geothermal power plant, the Geysers in California, for example, production peaked in the late 1980s and then the project literally began running out of steam.
  • Wind power. According to the American Wind Energy Association, the 5,700 turbines installed in the United States in 2009 required approximately 36,000 miles of steel rebar and 1.7 million cubic yards of concrete (enough to pave a four-foot-wide, 7,630-mile-long sidewalk). The gearbox of a two-megawatt wind turbine contains about 800 pounds of neodymium and 130 pounds of dysprosium -- rare earth metals that are rare because they're found in scattered deposits, rather than in concentrated ores, and are difficult to extract.
  • Biomass.
  • t expanding energy crops will mean less land for food production, recreation, and wildlife habitat. In many parts of the world where biomass is already used extensively to heat homes and cook meals, this renewable energy is responsible for severe deforestation and air pollution
  • Hydropower.
  • "renewable energy" is a meaningless term with no established standards.
  • The amount of concrete and steel in a wind-tower foundation is nothing compared with Grand Coulee or Three Gorges, and dams have an unfortunate habit of hoarding sediment and making fish, well, non-renewable.
  • All of these technologies also require electricity transmission from rural areas to population centers. Wilderness is not renewable once roads and power-line corridors fragment it
  • the life expectancy of a solar panel or wind turbine is actually shorter than that of a conventional power plant.
  • meeting the world's total energy demands in 2030 with renewable energy alone would take an estimated 3.8 million wind turbines (each with twice the capacity of today's largest machines), 720,000 wave devices, 5,350 geothermal plants, 900 hydroelectric plants, 490,000 tidal turbines, 1.7 billion rooftop photovoltaic systems, 40,000 solar photovoltaic plants, and 49,000 concentrated solar power systems. That's a heckuva lot of neodymium.
  • hydroelectric power from dams is a proved technology. It already supplies about 16 percent of the world's electricity, far more than all other renewable sources combined.
  • None of our current energy technologies are truly renewable, at least not in the way they are currently being deployed. We haven't discovered any form of energy that is completely clean and recyclable, and the notion that such an energy source can ever be found is a mirage.
  • Long did the math for California and discovered that even if the state replaced or retrofitted every building to very high efficiency standards, ran almost all of its cars on electricity, and doubled its electricity-generation capacity while simultaneously replacing it with emissions-free energy sources, California could only reduce emissions by perhaps 60 percent below 1990 levels -- far less than its 80 percent target. Long says reaching that target "will take new technology."
  • it will also take a new honesty about the limitations of technology
