'Absolutely No Progress Being Made' at Fukushima Nuke Plant, Undercover Reporter Says [... - 0 views

  • "Absolutely no progress is being made" towards the final resolution of the crisis, Suzuki told reporters at a Foreign Correspondents' Club of Japan news conference on Dec. 15. Suzuki, 55, worked for a Toshiba Corp. subsidiary as a general laborer there from July 13 to Aug. 22, documenting sloppy repair work, companies including plant operator Tokyo Electric Power Co. (TEPCO) playing fast and loose with their workers' radiation doses, and a marked concern for appearances over the safety of employees or the public.
  • For example, the no-entry zones around the plant -- the 20-kilometer radius exclusion zone and the extension covering most of the village of Iitate and other municipalities -- have more to do with convenience that actual safety, Suzuki says. "(Nuclear) technology experts I've spoken to say that there are people living in areas where no one should be. It's almost as though they're living inside a nuclear plant," says Suzuki. Based on this and his own radiation readings, he believes the 80-kilometer-radius evacuation advisory issued by the United States government after the meltdowns was "about right," adding that the government probably decided on the current no-go zones to avoid the immense task of evacuating larger cities like Iwaki and Fukushima.
  • The situation at the plant itself is no better, where he says much of the work is simply "for show," fraught with corporate jealousies and secretiveness and "completely different" from the "all-Japan" cooperative effort being presented by the government.

  • "Reactor makers Toshiba and Hitachi (brought in to help resolve the crisis) each have their own technology, and they don't talk to each other. Toshiba doesn't tell Hitachi what it's doing, and Hitachi doesn't tell Toshiba what it's doing." Meanwhile, despite there being no concrete data on the state of the reactor cores, claims by the government and TEPCO that the disaster is under control and that the reactors are on-schedule for a cold shutdown by the year's end have promoted a breakneck work schedule, leading to shoddy repairs and habitual disregard for worker safety, he said.
  • "Working at Fukushima is equivalent to being given an order to die," Suzuki quoted one nuclear-related company source as saying. He says plant workers regularly manipulate their radiation readings by reversing their dosimeters or putting them in their socks, giving them an extra 10 to 30 minutes on-site before they reach their daily dosage limit. In extreme cases, Suzuki said, workers even leave the radiation meters in their dormitories.
  • According to Suzuki, TEPCO and the subcontractors at the plant never explicitly tell the workers to take these measures. Instead the workers are simply assigned projects that would be impossible to complete on time without manipulating the dosage numbers, and whether through a sense of duty or fear of being fired, the workers never complain. Furthermore, the daily radiation screenings are "essentially an act," with the detector passed too quickly over each worker, while "the line to the buzzer that is supposed to sound when there's a problem has been cut," Suzuki said.

Japan's Toshiba eyes nuclear power alliance [14Aug12] - 0 views

  • Toshiba plans to sell some of its controlling stake in nuclear-power unit Westinghouse Electric as it looks to form an alliance to tap demand in emerging markets, reports said Tuesday. The Japanese engineering giant, which holds about 67 percent of Westinghouse, said it would sell as much as 16 percent of the US firm to buyers with a foothold in nations eager to build nuclear plants, after demand in post-Fukushima Japan fell away.

Japan, Vietnam Move Ahead On Nuclear Reactor Plans, Despite Fukushima [28Sep11] - 0 views

  • In Japan's most aggressive move to promote exports of nuclear technology since the Fukushima Daiichi accident in March, a Tokyo-based utility consortium signed a deal with Vietnam on Wednesday to conduct a feasibility study for two new reactors. The agreement comes as a lifeline to Japan's nuclear industry, which harbors ambitions of expanding abroad, even as its future is in doubt at home. Amid a post-disaster reassessment of energy policy, the government has vowed to reduce dependence on nuclear power for domestic electricity generation. But it has continued to push nuclear technology in overseas markets.
  • For Vietnam, where rapid economic growth has increased demand for electricity, the contract with Japan Atomic Power Co. offers a way to diversify its energy mix beyond two Russian nuclear reactors currently under construction. The Vietnamese government said last year it plans 13 nuclear reactors at eight separate plants with a combined capacity of 15,000 megawatts by 2030. "This important milestone ... shows Vietnam's determination to develop nuclear power plants, especially in the face of global economic difficulties and after the incident at Japan's Fukushima plant," Vietnamese Deputy Minister of Industry and Trade Hoang Quoc Vuong said at the signing ceremony in Hanoi. He said he expects nuclear power to account for 7% of Vietnam's installed generation capacity by 2030.
  • Lessons from the Fukushima disaster will be taken into account in the Vietnamese project, according to officials from Japan Atomic Power, a consortium of Japan's nine nuclear utilities, including Fukushima Daiichi plant operator Tokyo Electric Power Co. (9501.TO). "We pledge to work hard to ensure the nuclear power development of Vietnam," said Japan Atomic Power President Yasuo Hamada. Vietnamese officials said Japan will build advanced boiling water reactors (ABWR), a type of technology used by Hitachi Ltd. (6501.TO) and Toshiba Corp. (6502.TO). But Japan Atomic Power officials in Tokyo said no decision had been made on the type or contractor for construction and operation.

  • On Thursday, a larger consortium of 13 Japanese companies, including the nine electric utilities, along with Hitachi and Toshiba, plan to sign another memorandum with Vietnam Electricity to start talks on reactor bids. That Tokyo-based entity, the International Nuclear Energy Development of Japan Co., was set up last year under the trade ministry to promote reactor exports. The Japanese government is expected to foot most of the bill for the plant through development aid and export promotion programs run by state-owned Japan Bank for International Cooperation and Nippon Export and Investment Insurance. It made a down payment on that by underwriting the entire Y2 billion ($26 million) cost of the 18-month feasibility study.

Proof Of Fukushima Weapons Program Rests On A Pile Of Manure[09Sep11] - 0 views

  • Soon after Japan's triple disaster, I suggested that an official cover-up of a nuclear-weapons program hidden inside the Fukushima No.1 plant was delaying the effort to contain the reactor meltdowns. Soon after the tsunami struck, the Tokyo Electric Power Company reported that only three reactors had been generating electricity on the afternoon of March 11.. (According to the initial report, these were the older GE-built reactors 1,2 and 6.). Yet overheating at five of the plant's six reactors indicated that two additional reactors had also been operating (the newer and more advanced Nos. 3 and 4, built by Toshiba and Hitachi). The only plausible purpose of such unscheduled operation is uranium enrichment toward the production of nuclear warhead
  • On my subsequent sojourns in Japan, other suspicious activities also pointed to a high-level cover-up, including systematic undercounts of radiation levels, inexplicable damage to thousands of imported dosimeters, armed anti-terrorism police aboard trains and inside the dead zone, the jamming of international phone calls, homing devices installed in the GPS of rented cars, and warning visits to contacts by government agents discouraging cooperation with independent investigations. These aggressive infringements on civil liberties cannot be shrugged off as an overreaction to a civil disaster but must have been invoked on grounds of national security.
  • One telltale sign of high-level interference was the refusal by science equipment manufacturers to sell isotope chromatography devices to non-governmental customers, even to organizations ready to pay $170,000 in cash for a single unit. These sensitive instruments can detect the presence of specific isotopes, for example cesium-137 and strontium-90. Whether uranium was being enriched at Fukushima could be determined by the ratio of isotopes from enriched weapons-grade fissile material versus residues from less concentrated fuel rods.

  • Now six months after the disaster, the smoking gun has finally surfaced, not on a Japanese paddy field but inside a pile of steer manure from a pasture near Sacramento, California
  • The sample of cattle dung and underlying soil was sent to the nuclear engineering lab of the University of California, Berkeley, which reported on September 6:
  • We tested a topsoil sample and a dried manure sample from the Sacramento area. The manure was produced by a cow long before Fukushima and left outside to dry; it was rained on back in March and April. Both samples showed detectable levels of Cs-134 and Cs-137, with the manure showing higher levels than the soil probably because of its different chemical properties and/or lower density. One interesting feature of t the Sacramento and Sonoma soil samples is that the ratio of Cesium-137 to Cesium-134 is very large - approximately 17.6 and 5.5, respectively. All of our other soil samples until now had shown ratios of between 1 and 2. We know from our air and rainwater measurements that material from Fukushima has a cesium ratio in the range of approximately 1.0 to 1.5, meaning that there is extra Cs-137 in these two soil samples. The best explanation is that in addition to Fukushima fallout, we have also detected atmospheric nuclear weapons testing fallout in these soils. Weapons fallout contains only Cs-137 (no Cs-134) and is known to be present in older soils ..Both of these samples come from older soils, while our samples until this point had come from newer soils.
  • The last atmospheric nuclear blast at the Nevada Test Site occurred in 1962, whereas the manure was presumably dropped less than 49 years ago. Over the past year, the approximate life-span of a cow patty, the rain that fell on the plain came not from a former province of Spain. Within that short time-frame, the only possible origin of radioactive fallout was Fukushima.To think otherwise would be lame.
  • Sun-dried manure is more absorbent than the rocky ground of Northern California, which explains the higher level in Sacramento dung than in the Sonoma soil. As a rule of thumb, the accuracy of radiation readings tends to improve with higher concentration of the test material.The manure acted like a sponge for the collection of radioactive rainfall. Its ratio of Cs-137 (resulting from enriched uranium) to Cs-134 (from a civilian fuel rod) is more than 17-to-1. Larger by 1,700 percent, this figure indicates fission of large amounts of weapons-grade material at Fukushima.
  • The recent higher readings were probably based on either late releases from a fire-destroyed extraction facility or the venting of reactor No.3, a Toshiba-designed unit that used plutonium and uranium mixed oxide or MOX fuel. Unannounced nighttime airborne releases in early May caused radiation burns in many people, as happened to my forearms. Those plumes then drifted toward North America.
  • Enrichment of uranium for nuclear warheads is prohibited under constitutional law in Japan and by terms of the Non-Proliferation Treaty. Since no suspects have been charged by prosecutors, this cannot be a plot by a few individuals but stands as the crime of a national entity.
  • Yellow-Cake Factory 608   Fukushima Province has a history of involvement in atomic weapons development, according to a New York Times article by Martin Fackler titled "Fukushima's Long Link to a Dark Nuclear Past" (Sept. 6). Following the lead of Japanese news reports, the correspondent visited the town of Ishikawa, less than an hour's drive south of the Fukushima No.1 nuclear plant. There he interviewed Kiwamu Ariga who as a student during the war was forced to mine uranium ore from a local foothill to supply the military-run Factory 608, which refined the ore into yellow-cake.
  • Several research groups worked on building a super-weapon for militarist Japan. The Naval Technology Research Institute was best-positioned due to its secret cooperation with the German Navy. Submarine U-234 was captured in the Atlantic after Germany's surrender with a cargo of uranium along with two dead passengers - Japanese military officers .Soon after departing Norway, U-864 was bombed and sunk, carrying a load of two tons of processed uranium..
  • In the article for the Atlanta Constitution, dated, Oct. 2, 1946, David Snell reported that the Japanese military had successfully tested a nuclear weapon off Konan on Aug. 12, 1945. There are detractors who dispute the account by a decommissioned Japanese intelligence officer to the American journalist, stationed in occupied Korea with the 24th Criminal Investigation Detachment of the U.S. Army. A cursory check on his background shows Snell to have been a credible reporter for Life magazine, who also contributed to the Smithsonian and The New Yorker magazines. A new book is being written by American and Russian co-authors on the Soviet shoot-down of the Hog Wild, a B-29 that flew over Konan island soon after the war's end..
  • Due to its endemic paranoia about all things nuclear, the U.S. government had a strong interest in suppressing the story of Japan's atomic bomb program during the war, just as Washington now maintains the tightest secrecy over the actual situation at Fukushima.
  • The emerging picture shows that nuclear-weapons development, initiated in 1954 by Prime Minister Nobusuke Kishi and supervised by Yasuhiro Nakasone, was centered inside civilian nuclear plants, since the Self-Defense Forces were bound by strict Constitutional rules against war-making and the Defense Agency is practically under the direct supervision of the U.S. Joint Chiefs of Staff. Funding came from the near-limitless budget of the Tokyo Electric Power Company (TEPCO), which today claims financial insolvency without explanation of how its vast cash holdings disappeared. A clandestine nuclear program must be expensive, since it would include the cost of buying the silence of parliament, the bureaucracy and foreign dignitaries.
  • Following the March 11 disaster, TEPCO sent a team of 250 emergency personnel into the plant, yet only 50 men were assigned to cooling the reactors. The other 200 personnel stayed out of sight, possibly to dismantle an underground plutonium-extraction facility. No foreign nuclear engineers or Japanese journalists were ever permitted entry into the reactor structures.   Radiation leakage from Fukushima No.1 prevented local police from rescuing hundreds of tsunami survivors in South Soma, many of whom consequently went unaided and died of wounds or exposure. Tens of thousands of farmers have lost their ancestral lands, while much of Japan's agriculture and natural areas are contaminated for several generations and possibly longer, for the remaining duration of the human species wherever uranium and plutonium particles have seeped into the aquifers.
  • TEPCO executives, state bureaucrats and physicists in charge of the secret nuclear program are evading justice in contempt of the Constitution. As in World War II, the Japanese conservatives in their maniacal campaign to eliminate their imagined enemies succeeded only in perpetrating crimes against humanity and annihilating their own nation. If history does repeat itself, Tokyo once again needs a tribunal to send another generation of Class-A criminals to the gallows.

South Africa Says 'No Decision Made' on Building Nuclear Plants [10Oct11] - 0 views

  • South Africa’s Department of Energy said reports of a tender process being under way for six new nuclear power plants “are factually incorrect.” “At no point has the government committed to build six new nuclear reactors,” the department said in an e-mailed statement today. The government "hasn’t selected any design, vendor nor suppliers of the nuclear power plants. No decision has been made on the actual number.’’ South Africa plans to diversify energy sources away from coal, which makes up more than 90 percent of its generation capacity of about 40,000 megawatts. It also aims to prevent a repeat of power outages in 2008 that temporarily shut most of the nation’s mines and smelters, its biggest source of foreign exchange.
  • Energy Minister Dipuo Peters has proposed a strategy for the roll-out of new nuclear power plants to the Cabinet, the ministry said. The government approved plans to boost its nuclear energy capacity by 9.6 electrical gigawatt, it said. Safety concerns following the meltdown of nuclear reactors in Fukushima, Japan, prompted Peters to postpone the opening of the bids until next year, she said on Sept. 15.
  • ‘Factually Incorrect’ The energy department’s statement said it “noted” an article published by the Mail & Guardian on Oct. 6. The newspaper listed potential bidders for a 1 trillion rand ($126 billion) tender to build six nuclear plants by 2030 as Areva SA, EDF SA (EDF), Toshiba Corp. (6502)’s Westinghouse Electric Corp. unit, China Guangdong Nuclear Power Holding Corp., Korea Electric Power Corp. (KEP) and Rosatom Corp. The report, which cited unidentified people in government and industry, is “full of statements that are not true and factually incorrect,” the Department of Energy said in its statement.

Speaking tour of Japan challenges financing for new U.S. reactors [20Aug10] - 0 views

  • Beyond Nuclear's Kevin Kamps toured Japan from August 2nd to 12th, visiting Tokyo, Fukushima, Fukui, Kansai and Kyushu. A highlight included meeting with officials from the Japan Bank for International Cooperation and the Nippon Export and Investment Insurance agency, where a letter signed by 75 U.S. national and grassroots groups was delivered, urging no Japanese financing for risky new reactors in the U.S. A backgrounder spelled out these risks in detail. Most proposed new U.S. atomic reactors have designs owned by Japanese companies -- either Toshiba (Westinghouse), Hitachi (General Electric), or Mitsubishi. At South Texas Project, Toshiba and Tokyo Electric Power Company are even partners in the venture. In addition, Japan Steel Works would be the primary supplier of large nuclear components, such as reactor pressure vessels and steam generators. The Japanese news media were alerted to the letter and meeting, and the Japanese Prime Minister, Minister of Finance, and Minister of Economy, Trade, and Industry received copies of the letter.

Actual workers talk about Fukushima [26Sep11] - 0 views

  • At the moment the conditions at Unit 1 of Fukushima nuclear power plant continues to be chaos, so Tadaharu Murakami (pseudonym), 30 years, an employee of a company that works as a subcontractor for Tokyo Electric Power. “The workers are not enough, TEPCO has recently committed even many people without experience who have never worked in a nuclear plant. As for the places of work, everything is really chaotic. It educates the people by giving them the ABCs teaches fundamental things such as wearing protective clothing like you.”
  • On The Pointy Guy) As a symbol of the discontent that elicits such a situation, there was an “incident” on 28 August has a live camera from TEPCO, which is mounted inside the block 1, sent pictures of a “mysterious” staff, who has placed himself in front of the lens and has said anything, while he pointed his finger at the camera. Murakami explains that after the conference on 30th August, during which expressed Yasuhiro Sonoda, responsible parliamentarians of the Cabinet, the wish that he would like to share the thoughts of “this person”, what he thinks, the guy who pretends to be that person and the real conditions on the website the bulletin board system of “2channel” has been disclosed. He has hit the nail on the head when he said that “for the people who work there, the working conditions are unfair and illegal. We have no insurance, we are poorly paid and we even have a contract. ”
  • Murakami confirmed, “that what he wrote on the Internet, the truth. Even when I worked before the accident in March as a temporary worker in Fukushima Daiichi have, you have promised me 15,000 yen a day and I’ve got nothing. “He continues,” when I asked at the sitting of the subcontractor, why do not they pay me what they owe me, they said, ‘You work for a subcontractor? So they have no right to make such a request.” I turned also to workers of TEPCO, which have responded harshly to me, I consider myself strictly to the rules of the line and that’s all. “I wait one more month and if they do not pay me, I’ll sue the subcontractor. “Murakami is confirmed by the descriptions, which are made on the internet about the poor accommodation,” even when it has cooled a bit in early September, break every day at least 10 workers due to fatigue together. I want them to rapidly improve the living conditions.”

This is the extreme main obstacle drive more radioactivity in the key zones.
  • On 1 August, measurements show in addition to an exhaust pipe between reactor 1 and 2 incredibly high readings, which can hardly believe it: 10,000 millisievert/hour! (Such a dose to take once meant certain death). From there it always escape greatly increased radiation doses. It has begun, and from there to discover little by little other zones, where the values are higher than 100 millisievert, zones which are provided with a cone that bears “forbidden access” the inscription, in the vicinity of such zones can not be work.
  • Even many experienced workers from the nuclear industry have refused to work in Fukushima, she said, “This is suicide,” because they know the effects of elevated radioactivity. To compensate for this, we hired more and more people without experience, instead of being useful to increase the chaos.” Whether you begin the process of establishing a decontamination system or whether the reactor buildings with a lack of protection surrounds, at the end are nothing more than the emergency measures.
  • You will not find a real solution that allows to separate the molten fuel rods, which are the cause of the diffusion of radioactive material when the technician can not approach the fast reactor core. In any case, it is an operation “almost impossible”, said the analysis by Masashi Goto, Toshiba developed for the nuclear reactor cores. “In the blocks 1, 2 and 3, there is a strong possibility that has emerged during the melting of nuclear fuel not only from the pressure vessel, but also from the protective sheath. At the moment nobody is able to determine, is melted in the extent and to what extent the core. I can not imagine how people can work there or at another location, where the danger has reached a point that nobody has ever experienced. “

NRC Has Authority to Deal With Seismic Risks, Lochbaum Says [29Sep11] - 0 views

  • Nuclear regulators already have “sufficient information and knowledge” to deal with earthquake risks at existing U.S. reactors and don’t need to wait for a broader review, a safety advocate said. The Nuclear Regulatory Commission developed seismic rules for new plants in 1996 and has since approved preliminary construction for proposed nuclear units at a Southern Co. plant in Georgia and certified an early reactor design by Toshiba Corp.’s Westinghouse Electric unit, according to comments filed with the agency today by David Lochbaum, director of the Nuclear Safety Project at the Cambridge, Massachusetts-based Union of Concerned Scientists.
  • “If the NRC truly lacks sufficient information about seismic hazards and how safety at nuclear power reactors is affected, then the agency cannot responsibly have issued early site permits and certified new reactor designs,” he said. The NRC is in the process of evaluating seismic hazards in the central and eastern U.S. in response to updated geologic information. By the end of this year, the agency plans to develop an earthquake probability model for reactor owners to use and may require all U.S. plants to review their seismic risks within the next two years.
  • The NRC has said “repeatedly” the broad seismic review “deals with an issue that fails to present an immediate safety concern,” Scott Burnell, an agency spokesman, said in an e- mail. Existing plants are built to “safely withstand the earthquakes at their sites,” he said. Earthquake Protections The NRC is weighing requirements to bolster plant protections against earthquakes and floods in the wake of the nuclear disaster in Japan caused by a March temblor and tsunami that led to radiation leaks and meltdowns at Tokyo Electric Power Co.’s Fukushima Dai-Ichi plant.

Radioactive waste piles up at Fukushima nuclear plant as disposal method remains in lim... - 0 views

  • Three months after the start of full-scale water circulation system operations at the crippled Fukushima No. 1 Nuclear Power Plant, high-level radioactive waste has kept piling up amid no clear indications of its final disposal destination. As of Sept. 27, plant operator Tokyo Electric Power Co. (TEPCO) had accumulated about 4,700 drums of radioactive waste after three months of cesium decontamination operations initially using U.S. and French equipment which was later joined by Toshiba Corp.’s “Sally” system in August. Since the start of October, TEPCO has conducted the plant’s water circulation operations using the Sally system alone while relegating its U.S. and French counterparts built by Kurion Inc. and Areva SA, respectively, to backups. The Kurion and Sally systems are designed to purify decontaminated water through an absorption unit called a “vessel” that contains zeolites. The vessel is changed every few days and the used vessels become radioactive waste. End Extract

Czechs plan to heavily expand nuclear power, angering anti-nuke neighbors [08Oct11] - 0 views

  • DUKOVANY NUCLEAR PLANT, Czech Republic — Surrounded by corn fields, bicycle routes and a nature reserve, the eight huge cooling towers of the Dukovany nuclear power plant have dominated the Czech countryside near the Austrian border for almost three decades.
  • Against the odds, the government has worked to keep it that way for many years to come.
  • Defying growing global skepticism over the use of atomic energy, it is planning to dramatically increase the country’s nuclear power production — a move that would give the country a place among Europe’s most nuclear-dependent nations.The Czech plan reflects a sharp division over nuclear use among European nations, and relations with neighboring countries that have decided to go nuclear free could be seriously harmed.
  • ...3 more annotations...
  • The Czechs argue nuclear energy is needed because it is a clean and cost efficient source.They currently rely on six nuclear reactors — four 440-megawatt reactors in Dukovany and two 1,000-megawatt reactors at another plant in Temelin located an hour’s drive north of the Austrian border — for 33 percent of their total electricity. The government hopes to at least double that output. “We consider increasing electricity production in nuclear plants from some 30 percent to about 60 percent by 2050,” Deputy Industry and Trade Minister Tomas Huner told the Associated Press. “We have been mining uranium and there’s no doubt nuclear energy is irreplaceable for us in the long term,” said Huner, whose ministry has to present the new energy overhaul for the next 50 years to the government by year’s end.
  • German Chancellor Angela Merkel’s government decided to phase out nuclear energy by 2022 following the March meltdown at Japan’s Fukushima plant, and Switzerland has followed suit. Austria abandoned nuclear energy after the 1986 Chernobyl nuclear disaster and strictly opposes the Czech nuclear program.Other former Soviet bloc nations, now in the EU, are following the Czechs’ lead on nuclear power — reflecting diverging economic needs between east and west.Slovakia is currently building more nuclear facilities. And Poland has engaged in talks with French, U.S. and Japanese firms about know-how and technology for its first nuclear installation to be completed by 2030.
  • A trio of big players — U.S.-based Westinghouse Electric Co., a subsidiary of Japan’s Toshiba Corp., France’s state-owned nuclear engineering giant Areva SA and a consortium led by Russia’s Atomstroyexport — are already bidding to win a lucrative multibillion tender to build two more reactors at the Temelin plant. The reactors are expected to be operational in the middle of the next decade.The plant has been heavily protested by Austrian environmentalists who demand it be closed because of security concerns. Czech authorities insist both plants are safe and will have no problems passing so-called nuclear reactor stress tests currently being conducted across Europe after the Japanese disaster.Opened a year before the Chernobyl disaster, Dukovany’s life was expected to expire in some 30 years. Germany is closing plants of the same age — but the Czechs refuse to do that despite international pressure.

Subsidies - Without generous public subsidies, "Many of the 104 reactors curr... - 0 views

  • ...Nor would any new reactors be built in the U.S. today, according to a comprehensive new report written by Doug Koplow of Earth Track for the Union of Concerned Scientists: "Nuclear Power: Still Not Viable Without Subsidies." Ironically, the report's major public unveiling took place on Capitol Hill on March 11 -- the very day the Fukushima nuclear catastrophe began. Since then, one of the lead new reactor proposals in the U.S. -- two new reactors targeted at the South Texas Project, next in line for a multi-billion dollar nuclear loan guarantee and loan backed by U.S. federal taxpayers -- has largely gone belly up: its major partners included Tokyo Electric Power Company (owner and operator of the Fukushima Daiichi nuclear power plant) and Hitachi (merged with General Electric, designer of the catastrophically failed Mark 1 Boiling Water Reactor), as well as Toshiba (Japanese owner of Westinghouse) and the Japan federal government's Bank for International Cooperation. The U.S. partner, NRG Energy of Princeton, NJ, has announced it will put no more money into the project, given the Fukushima nuclear catastrophe. Koplow's report is very likely the single most comprehensive accounting yet of more than half a century of lavish taxpayer and ratepayer subsidization of the nuclear power industry in the U.S. -- often without the public's knowledge, let alone consent. Koplow has concluded that “After 50 years, the nuclear industry needs to move away from government patronage to a model based on real economic viability. The considerable operational and construction risks of this power source need to be reflected in the delivered price of power rather than dumped onto taxpayers.”

U.S., Japanese, and Mongolian nuclear establishments conspire to dump high-le... - 0 views

  • Reuters cites a Mainichi Daily report that such U.S.-Japanese nuclear industry corporate players as General Electric-Hitachi and Toshiba-Westinghouse, in cahoots with Japanese federal ministries and the Mongolian government's uranium mining and nuclear development arm, were close to finalizing a deal on turning Mongolia into an international dumpsite for irradiated nuclear fuel, until the Fukushima Daiichi nuclear catastrophe derailed the schedule. Undeterred by that, the partners in crime (or, at least it should be a crime) are still pursuing the plan.

Miami Herald: Outer shield of new reactors could shatter like a 'glass cup' -NRC lead r... - 0 views

  • Miami, Oct. 16 –Headline: ‘Fukushima disaster can happen here’ Today’s Miami Herald has an article warning South Florida residents they “should take little comfort in assurances that a Fukushima-type catastrophe could not happen here.” It notes that the Miami-area nuclear power plant, Turkey Point, “is just as reliant as Fukushima on offsite electricity, emergency electrical generators and batteries.” Yet, Florida Power & Light (FPL) is trying to build two new reactors at the site, making a total of four.
  • These two proposed reactors, the AP1000 design, are essentially “experimental” and “have never been tested or operated commercially at full scale”. The reactor design has “drawn substantial criticism on safety issues”. The article reviews three of these: 1) “One major issue is that the steel inner-containment structure is barely strong enough to keep radioactivity from escaping during a ‘design basis accident.’ This leaves little margin for error when the steel containment structure eventually corrodes and loses strength. Such corrosion is a common problem in older reactors.” 2) “The British Nuclear Installations Inspectorate has criticized Toshiba/Westinghouse for not sufficiently demonstrating that the outer concrete shield can withstand an external shock, such as an earthquake, hurricane, tornado or impact from a commercial aircraft crash.” 3) “Perhaps, the most damaging criticism comes from Dr. John Ma, the lead structural reviewer evaluating the outer concrete shield for the U.S. Nuclear Regulatory Commission (NRC). Dr. Ma submitted a ‘nonconcurrence statement of dissent’ stating that the outer shield could shatter like a ‘glass cup’ in an earthquake or commercial aircraft crash.”

Shutdown of Fukushima Reactors Is Ahead of Schedule [Nov11] - 0 views

  • Editor's Note: This is part of the IEEE Spectrum special report: Fukushima and the Future of Nuclear Power.
  • This past April, when the Japanese government and Tokyo Electric Power Co. (TEPCO) jointly unveiled their plan to bring the damaged reactors of the Fukushima Dai-ichi nuclear power plant to a cold shutdown and gain control of the release of radioactive materials, they set a tentative completion date for mid-January 2012. And "tentative" had to be the operative word, for the obstacles TEPCO faced—and to some extent still does face—are challenging in the extreme. They include:
  • Fuel rod meltdowns in reactors 1, 2, and 3 due to loss of cooling systems following the 11 March earthquake and tsunami; Severe damage to the upper levels of reactor buildings 1, 3, and 4 and slight damage to building 2, stemming from hydrogen explosions; High levels of radiation and contaminated rubble, making working conditions hazardous and difficult; Thousands of metric tons of contaminated water accumulating on the site and leaking out of the reactors.
  • ...5 more annotations...
  • It appears, however, that the process is now ahead of schedule. Environment Minister Goshi Hosono, who is also in charge of the Fukushima nuclear accident recovery, told the International Atomic Energy Agency's annual general conference in Vienna on 19 September that Japan was now aiming to complete a cold shutdown of the Fukushima plant by December 2011, instead of mid-January 2012. Progress was already evident in July, when Hosono announced that workers had completed step 1 of the two-step road map on schedule, reducing radioactive emissions and starting to bring down the core temperatures in reactors 1, 2, and 3. Hosono attributed the success to the construction of a new cooling system, which had begun pumping water into all three damaged reactors. In addition to cooling, the system also decontaminates the water accumulating in the basements of the reactor and turbine buildings. The contamination is the result of injected water coming into contact with the molten fuel in the pressure vessels.
  • Critics, however, were quick to question the stability of the system and its ad hoc design. The combination of filtering and decontamination technologies—mainly from the French nuclear giant Areva and the U.S. nuclear waste management company Kurion—includes some 4 kilometers of piping. The critics have a point. Even with the addition of a reportedly more robust system (to be used in parallel or as backup as needed) from Toshiba and IHI Corp., TEPCO admits the system underwent 39 disruptions between 10 July and 8 September. One consequence is that roughly 100 000 metric tons of water still need to be decontaminated.
  • Disruptions and remaining challenges notwithstanding, TEPCO has been making progress toward step 2 of the road map: a cold shutdown. According to TEPCO, that means achieving and maintaining a temperature of less than 100 °C as measured at the bottom of a reactor pressure vessel—the steel vessel containing the fuel rods—which itself is enclosed inside a protective containment vessel. A major advance came at the beginning of September, when TEPCO was able to start up the core spray lines to cool reactors 1 and 3. The core spray lines apply water directly to the cores from above, while the system installed in July has been cooling the cores by injecting water from the bottom. TEPCO has also begun increasing the amount of water being injected into reactor 2. The core spray line could not be used until recently because TEPCO first had to survey the subsystem's piping and valves. Given the high radiation in the area, this was difficult, but workers completed the job in July and confirmed the system's operability in August.
  • By late September, as a result of these efforts, the temperatures in all three reactors had dropped below 100 °C for the first time since the accident. As of 29 September, the temperatures for reactors 1, 2, and 3, respectively, were 77.5 °C, 99.7 °C, and 78.7 °C. "We are steadily bringing the postaccident situation under control," says Hosono. "To achieve step 2 this year, we'll move the schedule forward and do our best." But Yoshinori Moriyama, deputy director-general of Japan's Nuclear and Industrial Safety Agency (NISA) is cautious. "We need to maintain this state over the midterm," he says. "Temporary lower temperatures and the nonrelease of radioactive substances do not immediately mean that this is a cold shutdown." In order for NISA to declare a cold shutdown, the temperatures must remain stable and below 100 °C into December. So NISA won't officially declare a cold shutdown until near the end of 2011.
  • Despite these positive developments, nuclear experts point out that achieving a cold shutdown does not make the troubled plant completely safe, given that even spent fuel continues to generate heat for years after use. And upon achieving a cold shutdown, TEPCO must take on a new series of challenges. These include finding where the injected water is escaping, stopping those leaks, dealing with the accumulated contaminated water, removing and storing the thousands of spent fuel rods from the pools in reactors 1 to 4, and then figuring out a way to remove the melted fuel. The last is a task that could take a decade or more, according to experts.
