FOX: Nuclear reactor halted on "suspicion of cracks"; "We have found anomalies," says B... - 0 views

  • Belgium has temporarily shut one of its seven nuclear power reactors on suspicion that one of its components might be cracked, the country’s atomic power regulator said Wednesday. “We have found anomalies,” said Karina De Beule, spokesman for the ACFN, the federal agency for nuclear control. The agency is “evaluating these anomalies, if they can cause cracks,” De Beule said

BBC News - Belgium plans to phase out nuclear power [31Oct11] - 0 views

  • Belgium's main political parties have agreed on a plan to shut down the country's two nuclear power stations, but they have not yet set a firm date. A new coalition government is being set up and the nuclear shutdown will be on its agenda, officials say. If alternative energy sources are found to fill the gap then the three oldest reactors will be shut down in 2015. Germany is the biggest industrial power to renounce nuclear energy since Japan's Fukushima disaster in March.
  • Belgium has seven reactors at two nuclear power stations, at Doel in the north and Tihange in the south. They are operated by Electrabel, which is part of GDF-Suez. The agreement reached on Sunday night confirms a decision taken in 2003, which was shelved during Belgium's political deadlock following the last government's collapse in April 2010. Belgium will need to replace 5,860 megawatts of power if it is to go ahead with the nuclear phase-out.

Fukushima Desolation Worst Since Nagasaki as Population Flees From Fallout [27Sep11] - 0 views

  • Beyond the police roadblocks that mark the no-go zone around Japan’s wrecked Fukushima nuclear plant, six-foot tall weeds invade rice paddies and vines gone wild strangle road signs along empty streets.
  • “Older folks want to return, but the young worry about radiation,” said Harada, whose family ran the farm for 40 years.
  • What’s emerging in Japan six months since the nuclear meltdown at the Tokyo Electric Power Co. plant is a radioactive zone bigger than that left by the 1945 atomic bombings at Hiroshima and Nagasaki. While nature reclaims the 20 kilometer (12 mile) no-go zone, Fukushima’s $3.2 billion-a-year farm industry is being devastated and tourists that hiked the prefecture’s mountains and surfed off its beaches have all but vanished.

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.

Areva, TVA Discuss Use of Mixed-Oxide Nuclear Fuel From Retired Weapons [21Feb11] - 1 views

  • French energy group Areva has entered tentative talks with the Tennessee Valley Authority that could pave the way for TVA’s nuclear plants to use fuel made from retired weapons. On Friday, the company announced it signed a letter of intent with TVA to initiate discussions on the use of fuel from the Department of Energy’s Mixed-Oxide Fuel Fabrication Facility. While it would not obligate TVA to use the fuel, the letter highlights the agency’s ongoing relationship with DOE in evaluating the fuel-from-weapons program
  • Scheduled to begin operating in 2016, the mixed-oxide facility at DOE’s Savannah River site in South Carolina will blend plutonium from disassembled weapons with depleted uranium oxide, according to the National Nuclear Security Administration. Using the fuel in commercial reactors would make the plutonium unfit for explosives and help meet a commitment made by the United States and Russia in 2000 to dispose of 68 metric tons of surplus plutonium. Shaw Areva MOX Services Llc. holds the contract to build and operate the South Carolina facility
  • According to NNSA, more than 30 commercial reactors currently use mixed-oxide fuel, including at plants in the United Kingdom, Germany, France, Belgium and Switzerland.

  • “As the world leader in MOX fuel production, Areva has a long, successful history of producing reliable mixed-oxide fuel in Europe and has many satisfied customers around the globe. We look forward to partnering with TVA as it evaluates the potential use of MOX fuel in its nuclear plants,” Jacques Besnainou, CEO of Areva North America, said in a release

Nuclear Stress tests take on Fukushima lessons [19Sep11] - 0 views

  • European regulators have been publishing progress reports on the program of stress tests being carried out at nuclear power plants in response to the Fukushima accident. In the weeks following the Fukushima accident, the European Council (EC) requested a review of safety at European nuclear power plants when faced by challenging situations. The criteria for the reviews, now known as stress tests, were produced for the European Commission by the European Nuclear Safety Regulatory Group (ENSREG). Progress reports were due to be submitted to the European Commission by 15 September, and many nuclear regulators and in some cases plant operators have published summaries, including regulators in Belgium, France, Hungary, Romania, Slovakia, Slovenia, Spain, Sweden and the UK.
  • The reports vary from country to country, but the take-home story emerging from the reports is that Europe's nuclear plants are generally well placed to withstand beyond-design-basis events. Some plants have already put into practice initial measures to improve safety in response to Fukushima, and the tests are bringing to light more measures that need to be taken to improve resilience on a plant-by-plant basis.   Some measures that have already been identified are simple to put into place: for example, housekeeping routines have been changed to reduce the potential for seismic interactions (where non-safety related equipment could impact or fall onto seismically qualified equipment) at UK power plants.
  • stress tests focus on three areas highlighted by events in Japan: external threats from earthquake and flooding, specifically tsunami; the consequences of loss of safety functions, that is, a total loss of electricity supply (also referred to as station black-out, or SBO), the loss of ultimate heat sink (UHS), or both; and issues connected with the management of severe accidents. The UHS is a medium to which the residual heat from the reactor is transferred, for example the sea or a river.

  • While tsunami are not foreseen as a problem in Europe, the plants have been obliged to consider other external and internal initiating events that could trigger a loss of safety functions.In France, a total of 150 nuclear facilities including operating reactors, reactors under construction, research reactors and other nuclear facilities are affected. In its progress report, French regulator Autorité de Sûreté Nucléaire (ASN) notes that the risk of similar phenomena to those that triggered the Fukushima accident is negligible and says that it prefers to submit a more comprehensive report for all of its affected installations later in the year. However, reports for the 80 facilities identified as priorities have been submitted and those for the country's 58 operating power reactors have already been published on the ASN's web site.
  • No fundamental weaknesses in the definition of design basis events or the safety systems to withstand them has been revealed for UK nuclear power plants from either the stress tests or from earlier national reviews, according to the progress report from the UK's Office for Nuclear Regulation (ONR). However, lessons are being learnt about improving resilience for beyond-design-basis events and removing or reducing cliff-edges, and will be applied in a timely manner, the regulator says.
  • Measures under consideration in the UK include the provision of additional local flood protection to key equipment and the provision of further emergency back-up equipment to provide cooling and power, while EDF Energy, operator of the country's AGRs and single PWR plant, is preparing additional studies to reconsider flood modelling for specific sites and to review recent climate change information that arrived subsequent to recent routine ten-yearly safety reviews. The main focus for the country's Magnox reactors will be to improve the reliability of cooling systems in the face of a variety of beyond-design-basis faults to reduce or minimise the potential for cliff-edges. Evaluations of findings are still ongoing. Operators have up to 31 October to make their full report back to their national regulator, and regulators have until 31 December to make their full reports to the European Commission.

Fukushima desolation worst since Hiroshima, Nagasaki [07Oct11] - 0 views

  • Beyond the police roadblocks that mark the no-go zone around the wrecked Fukushima No. 1 nuclear plant, 2-meter-tall weeds invade rice paddies and vines gone wild strangle road signs along empty streets. Takako Harada, 80, returned to an evacuated area of Iitate, a village in Fukushima Prefecture, to retrieve her car. Beside her house is an empty cattle pen, the 100 cows slaughtered on government orders after radiation from the March 11 atomic disaster saturated the area, forcing 160,000 people to move away and leaving some places uninhabitable for two decades or more. "Older folks want to return, but the young worry about radiation," said Harada, whose family ran the farm for 40 years. "I want to farm, but will we be able to sell anything?"
  • What is emerging six months since the nuclear meltdowns at the Tokyo Electric Power Co. plant is a radioactive zone bigger than that left by the 1945 atomic bombings at Hiroshima and Nagasaki.
  • While nature reclaims the 20-km no-go zone, Fukushima's ¥240 billion a year farm industry is being devastated and tourists that hiked the prefecture's mountains and surfed off its beaches have all but vanished.

  • A government panel investigating Tepco's finances estimated the cost of compensation to people affected by the nuclear disaster will exceed ¥4 trillion.
  • The bulk of radioactive contamination cuts a 5- to 10-km-wide swath of land running as far as 30 km northwest of the nuclear plant, surveys of radiation hot spots by the science ministry show. The government extended evacuations beyond the 20-km zone in April to cover this corridor, which includes parts of Iitate.
  • No formal evacuation zone was set up in Hiroshima after the U.S. dropped an atomic bomb on the city on Aug. 6, 1945, though as the city rebuilt relatively few people lived within 1 km of the hypocenter, according to the Hiroshima Atomic Bomb Museum. Food shortages forced a partial evacuation of the city in summer 1946.
  • On April 26, 1986, an explosion at the Chernobyl reactor hurled 180 metric tons of nuclear fuel into the atmosphere, creating the world's first exclusion zone of 30 km around a nuclear plant. A quarter of a century later, the zone is still classed as uninhabitable. About 300 residents have returned despite government restrictions.
  • Tepco's decision in the 1960s to name its atomic plant Fukushima No. 1 has today associated a prefecture of about 2 million people that's almost half the size of Belgium with radiation contamination. In contrast, Chernobyl is the name of a small town near the namesake plant in what today is Ukraine.
  • Some people believed A-bomb survivors could emit radiation and others feared radiation caused genetic mutations, said Evan Douple, associate chief of research at the Radiation Effects Research Foundation in Hiroshima. An examination of more than 77,000 first-generation children in Hiroshima and Nagasaki after the bombings found no evidence of mutations, he said.
  • While radiation readings are lower in Fukushima than Hiroshima, Abel Gonzales, the vice chairman of the International Commission on Radiological Protection, said similar prejudices may emerge. "Stigma. I have the feeling that in Fukushima this will be a very big problem," Gonzales said during a symposium held in the city of Fukushima on the six-month anniversary of the disaster. Some children who fled Fukushima are finding out what Gonzales means. Fukushima schoolchildren were being bullied at their new school in Chiba Prefecture for "carrying radiation," the Sankei Shimbun reported in April, citing complaints made to education authorities. An 11-year-old Fukushima boy was hospitalized in Niigata Prefecture after being bullied at his new school, Kyodo News reported April 23.
  • Radiation risks in the 20-km zone forced the evacuation of about 8 percent, or 160,000, of some 2 million people who live in Fukushima. Almost 56,000 were sent to areas outside Fukushima, prefecture spokesman Masato Abe said. More than 8,000 left on their own accord because of radiation fears, Abe said
  • side the evacuation areas, levels of radiation higher than the government's criteria for evacuation have been recorded at 89 of 210 monitoring posts. At 24 of the sites, the reading was higher than the level at which the International Atomic Energy Agency says increases the risk of cancer. Japan Atomic Energy Institute researcher Toshimitsu Homma used science ministry data to compare the geographic scale of the contamination in Fukushima with Chernobyl.
  • He estimates the no-go zone in Fukushima will cover 132 sq. km, surrounded by a permanent monitoring area of 264 sq. km, assuming Japan follows the criteria set by the Soviet Union in 1986. The two areas combined equal about half the size of the five boroughs that comprise New York City. In the case of Chernobyl, the two zones cover a land mass 25 times greater, according to Homma's figures.
  • "Contradiction in some official statements, and the appearance of nonscientifically based 'expert' voices, confused and added stress to the local populations in each case," said Evelyn Bromet, a distinguished professor in the department of psychiatry at State University of New York, Stony Brook. "Lies got told, contradictions got told. In the end it's easier to believe nobody," Bromet said in an interview, citing mental health studies she did on people in the areas.
  • What radiation hasn't ruined, the earthquake and tsunami devastated. Fukushima Prefecture welcomed 56 million domestic and overseas visitors in 2009, equal to 44 percent of Japan's population.
  • The coastal town of Minamisoma this year canceled its annual qualifying stage for the world surfing championship, part of a waterfront that lured 84,000 beachgoers in July and August last year, said Hiroshi Tadano, head of the town's economic division. This year, nobody visited the beaches in the two months. "Most of the beaches are destroyed," Tadano said. "And of course, radiation played its part."
  • The area's biggest festival, Soma Nomaoi, a re-enactment of samurai battles, attracted 200,000 visitors last year. This year 37,000 came. Of the 300 horses typically used in the event, 100 were drowned in the tsunami and another 100 were evacuated due to radiation, Tajino said. Minamisoma resident Miyaguchi, 54, lost his home and parents in the tsunami. He quit his job at Tepco, leaving him unemployed and housed in an evacuation center

Nuclear workers dosed with Plutonium during mishap [06Oct11] - 0 views

  • SOURCE: Nuclear inspectors exposed to radiation, Nature.com, October 05, 2011 Today, the International Atomic Energy Agency (IAEA) reported that one of its nuclear inspectors had been exposed to radiation during a 4 October inspection of the Belgoprocess nuclear waste facility in Dessel, Belgium. The inspector, along with an inspector from EURATOM and a Belgoprocess employee, apparently received a dose of radiation after a vial or flask of plutonium accidentally fell on the floor, according to releases from the company and the Belgian Federal Nuclear Control Agency (AFCN).
