"Besides, Russia has a great deal to gain by exploiting the agreement on civil nuclear cooperation with the US, signed on the sidelines of the "lobster summit" between Presidents George W Bush and Vladimir Putin on July 2, which is a major concession by Washington, allowing Russia to set up facilities for reprocessing spent nuclear fuel of US origin on commercial terms - a highly lucrative business indeed. In immediate terms, Washington's concession has opened the way for Russia to reprocess the spent fuel of US origin from South Korea and Taiwan." Det giver sandelig grund til bekymring for miljøet !!!

160311, Newsmax GE Sclentist Quit Over Troubled Reactors. Scientist Dale Bridenbaugh and two colleagues at General Electric quit their jobs in the 1970s to express their concern about the company's Mark 1 nuclear reactor — the design of the troubled reactors at the Fukushima Daiichi plant in Japan.
160311, Benzinga, Dangers Of General Electric's Mark 1 Reactors Known For 40 Years. As far back as 1972, there were warnings that, if a Mark 1 reactor's cooling system failed, the fuel rods would overheat and, as a result, the primary containment vessel surrounding the reactor would burst, spilling radiation into the environment. That warning is dangerously close to becoming a premonitlon, with a containment vessel damaged at the Fukushima Daiichi nuclear plant in Japan. ... Stephen H. Hanauer, then a safety official with the Atomic Energy Commission said 1972 that the Mark 1 system should be discontinued because, among other concerns, the smaller containment design is more susceptible to explosion and rupture from a buildup of hydrogen, which may be the case at Fukushima Daiichi. Also in 1972, Joseph HenGdry, who later became the chairman of the Nuclear Regulatory Commission, said that while the idea of banning Mark 1 systems was attractive, it could also spell "the end of nuclear power" due to the fact that the technology had become so widely accepted. ... In the late 1980s, Mark 1 reactors in the United States were retrofitted with venting systems to help ease pressure in overheating situations, after Harold Denton, an official with the Nuclear Regulatory Committee, said that Mark 1 had a 90 percent probability of bursting if the fuel rods were to overheat and melt in an accident.
270311, Reuters, Low-level radiation found in Massachusetts rainwater. .. The low level of radioiodine-131 detected in precipitation at a sample location in Massachusetts is comparable to findings in California, Washington state and Pennsylvania and poses no threat to drinking supplies, public health officials said. ... Trace amounts of radiation believed to have originated from damaged Fukushima Daiichi reactors in the aftermath of Japan's devastating 9.0 earthquake on March 11 have also been detected in air samples in several western U.S. States, but at levels so small they posed no risk to human health.
hentet 290311, jconline, Radiation in Japan seawater, soil may be spreading. The [radioactive] water, must be removed and safely stored before work can continue to power up the plant's regular cooling system, nuclear safety officials said. ... Workers also discovered radioactive water in the deep trenches outside three units, with the airborne radiation levels outside Unit 2 exceeding 1,000 millisieverts per hour - more than four times the amount hat the government considers safe for workers, TEPCO said Monday. .... the contamination in Unit 2 appeared to be due to a partial meltdown of the reactor core. A TEPCO spokesman said the presence of radioactive chemicals such as iodine and cesium point to damaged fuel rods as the source. .... New readings show contamination in the ocean has spread about a mile (1.6 kilometers) farther north of the nuclear site lan before. ... Meanwhile, a strong earthquake shook the region and prompted a brief tsunami alert. .... Scores of strong earthquakes have rattled Japan over the past two weeks, adding to the sense of unease across Japan, where the final death toll from the March 11 disasters is expected to top 18,000 and hundreds of thousands remain homeless. ... TEPCO officials said Sunday that radiation in leaking water in Unit 2 was 10 million times above normal - an apparent spike that sent employees fleeing. The day ended with officials saying the huge figure had been miscalculated and was 100,000 times above normal, still very high but far better than the earlier results.
140311, Spiegel, Nuclear Disaster Will Have Political Impact as Great as 9/11. The nuclear disaster in Fukushima makes it hard to ignore the vulnurabilities of the technology. It could spell the end of nuclear power, German commentators argue on Monday. The government in Berlin may now cave in to mounting pressure to suspend its 12-year extension of reactor lifetimes, they say. ... Chancellor Angela Merkel's coalition of conservatives and the pro-business Free Democratic Party (FDP) reversed the planned phaseout of the 17 nuclear reactors by 2021, amending a decision taken by a previous center-left government in 2002 to end nuclear power generation in Germany. ... A majority of Germans are opposed to nuclear power and the Fukushima accident is becoming a campaign issue ahead of state elections, the most important of which is being held in the conservative-ruled and wealthy state of Baden-Württemberg on March 27. .... On Monday, support in Merkel's coalition for extending nuclear lifetimes started to crumble. Foreign Minister Guido Westerwelle, the leader of the FDP, called for a safety review at all German nuclear plants. Power stations whose cooling systems were found to lack multiple safety levels would have to be switched off "until the situation is totally clear." ... "The safety precautions (at the Japanese nuclear plant) weren't just insufficient; the operating company TEPCO systematically breached them, as the government ascertained in 2002. TEPCO falsified security reports in more than 200 cases. .. the often incompetent and corrupt governments were never voted out of office. The perestroika that Japan so urgently needs has scarcely begun," ... "It was always said that danger only came from rickety old reactors in former Eastern Bloc states - while conveniently ignoring that Sweden [!!!!!, OJ], France or the United States kept on narrowly avoiding maximum credible accidents. ... "That is over now. Faith in redundant, coincidence-proof security precautions has been wiped out by Fukushima. The high-tech democracy Japan has shown what could happen if an Internet attack on German or French nuclear reactors were to happen as it did with the 'Stuxnet' program against the Iranian nuclear program. ... 'The nuclear accident is giving even firm supporters of nuclear power cause for thought, because the unthinkable happened in Fukushima. But even if we wanted to, we couldn't switch off all nuclear reactors overnight. Because the lights would literally go out. The maximum credible accident of Fukushima forces us to check the safety standards of our nuclear power stations. And to think harder about the quickest possible way to get out of nuclear power generation." ... Then and ever since, the builders of nuclear power stations in Europe, North America and Japan boasted that a serious accident could be virtually ruled out thanks to superior Western Nuclear technology." ... "The disaster at Fushima shows: It's simply not true. "It is unlikely to be a coincidence that it was an old reactor with a design from the 1960s that got into trouble. The technology of this type of plant, which also operates in Germany, is outdated. Its safety level is significantly below that of modern nuclear plants, they wouldn't get construction approval these days. The accident has reinforced the lessons to be drawn from this: The plants that were originally intended for a lifespan of 40 years must not have their lifetimes extended, is being done everywhere both in the West and the East -- because It yields major profits for the operators." On the contrary: the old reactors in particular must be taken off the grid as soon as possible.

220311, bloomberg, Jason Clenfield - Fukushima Engineer Says He Helped Cover Up Flaw at Dai-Ichi Reactor No. 4 - Mitsuhiko Tanaka says he helped conceal a manufacturing defect in the $250 million steel Vessel installed at the Fukushima Dai-Ichi No. 4 reactor while working for a unit of Hitachi Ltd. in 1974. ... Tanaka says the reactor pressure vessel inside Fukushima's unit No. 4 was damaged at a Babcock-Hitachi foundry in Kure City, in Hiroshima prefecture, during the last step of a manufacturing process that took 2 ½ years and cost tens of millions of dollars. If the mistake had been discovered, the company might have been bankrupted, he said. ... After a month of computer modeling, Tanaka came up with a way to use pumpjacks to pop out the sunken wall. While it would look like nothing had ever happened, no-one knew what the effect of the repair would have on the integrity of the vessel. [Det er ikke den, der er gået, men hvornår sker det ! i 1988] .. Tanaka says he went to the Trade Ministry to report the cover-up he'd been involved in more than a decade earlier. The government refused to investigate and Hitachi denied his accusations, he said.
230311, Counterpunch, HIROSE TAKASHI, Introduced by Douglas Lummis, What They're Covering Up at Fukushima ... Hirose Takashi has written a whole shelf full of books, mostly on the nuclear power industry and the military-industrial complex. Probably his best known book is Nuclear Power Plants for Tokyo in which he took the logic of the nuke promoters to its logical conclusion: if you are so sure that they're safe, why not build them in the center of the city, instead of hundreds of miles away where you lose half the electricity in the wires? [Et særdeles relevant og afslørende spørgsmål !!] ... After reading his account, you will wonder, why do they keep on sprinkling water on the reactors, rather than accept the sarcophagus solution [i.e., entombing the reactors in concrete. Editors.] ... But more importantly, accepting the sarcophagus solution means admitting that they were wrong, and that they couldn't fix the things. ... Hirose: ... If you want to cool a reactor down with water, you have to circulate the water inside and carry the heat away, otherwise it has no meaning. So the only solution is to reconnect the electricity. Otherwise it's like pouring water on lava. ... Here's what it looks like underneath a reactor container (shows a photograph). This is the butt end of the reactor. Take a look. It's a forest of switch levers and wires and pipes. ... You pour salt water on a hot kiln and what do you think happens? You get salt. The salt will get into all these valves and cause them to freeze. They won't move ... Hirose: In principle, it can't. Because even when a reactor is in good shape, it requires constant control to keep the temperature down to where it is barely safe. ... If I were Prime Minister Kan, I would order them to do what the Soviet Union did when the Chernobyl reactor blew up, the sarcophagus solution, bury the whole thing under cement, put every cement company in Japan to work, and dump cement over it from the sky. Because you have to assume the worst case. Why? Because in Fukushima there is the Daiichi Plant with six reactors and the Daini Plant with four for a total of ten reactors. ... As you know, of the six reactors at Daiichi, four are in a crisis state. ... Hirose: For example, yesterday. Around Fukushima Daiichi Station they measured 400 millisieverts - that's per hour. With this measurement (Chief Cabinet Secretary) Edano admitted for the first time that there was a danger to health, but he didn't explain what this means. ... They are saying stupid things like, why, we are exposed to radiation all the time in our daily life, we get radiation from outer space. But that's one millisievert per year. A year has 365 days, a day has 24 hours; Multiply 365 by 24, you get 8760. Multiply the 400 millisieverts by that, you get 3,500,000 the normal dose..... What is dangerous is when that material enters your body and irradiates it from inside. These industry-mouthpiece scholars come on TV and what to they say? They say as you move away the radiation is reduced in inverse ratio to the square of the distance. I want to say the reverse. Internal irradiation happens when radioactive material is ingested into the body. What happens? Say there is a nuclear particle one meter away from you. You breathe it in, it sticks inside your body; the distance between you and it is now at the micron level. One meter is 1000 millimeters, one micron is one thousandth of a millimeter. That's a thousand times a thousand: a thousand squared. That's the real meaning of "inverse ratio of the square of the distance." Radiation exposure is increased by a factor of a trillion. [Jeg får det nu til 1 million - men det rækker]. Inhaling even the tiniest particle, that's the danger.
060411, AlterNet: Susanne Rust, Radiation From Japan's Nuclear Meltdown Finds Its Way Into Califomia's Milk ... Last week, samples taken from a farm in San Luis Obispo and Spokane, Wash., showed contamination with low levels of the radioactive isotope, iodine 131. ... A coalition of scientists and environmentalists insisted ingesting radiation is not the same as background exposures from airplane flights. .... Indeed, just how radioactive particles - particularly iodine 131 and the more dangerous Cesium 137 - move through the food chain remains unclear. .... a contaminated milk supply represents a continuous and chronic exposure. [for den der drikker mælken - indtil radioaktiviteten af de optagne partikler er slut - det afhænger af den pågældende isotops halveringstid OJ] .... What about mothers who are breast-feeding? Presumably, if cows, sheep and goats can pass radiation along in their milk, so can humans. ... 'No mother should ever have to wonder if the milk she feeds her child might be harmful," he wrote in a statement. "Having worked on nuclear issues for 25 years, I know the difference between internal exposures and background radiation. But lots of people don't. As the father of an 11-month old daughter, I'm personally furious at the government for this misleading information."
090411, Hawaii News Now, Japan bans planting rice in radioactive soil. Fears of radiation spread to rice as the planting season began in Japan, prompting the government to ban its cultivation in contaminated soil as fallout leaking from a tsunami-damaged nuclear plant dealt another blow to the national diet. Vegetables and milk were the first foods that sparked concerns. . ... But those worries intensified when highly radioactive water wvas spotted gushing from the complex into the Pacific and contaminated fish showed up in catches. .... But rice has now come under the microscope as the planting season begins in April and May. .... The ban will apply to any soil found to contain high levels of radioactive cesium, and farmers who cannot grow rice will be compensated. Rice grown in uncontaminated soil will be screened. [og det er vigtigt - også for at forebygge snyd.] ... [rice] It's the key ingredient in sake, and citizens proudly buy locally grown varieties. ... In an unusual - and controversial - plan, engineers decided earlier this month to deliberately pump less contaminated water into the ocean from a storage facility they thought might make a good receptacle for the more highly radioactive water. [At det var "controversial" siger sig selv, der er vel næppe noget ringere sted for radioaktivt affald end netop havet - eller luften ! Det betyder at det når helt frem til os i sidste ende.] ... On Saturday, two 190,000-pound (86,000-kilogram) concrete pumps that have been retrofitted to spray water [det lyder også helt forkert, så spreder man jo radioaktiviteten ud i luften] and can be operated by remote control were on their way. ... Concerns about food have led several countries, most recently China, to ban imports of some items from Japan. ... So far, soil containing cesium that exceeds the new limit has been found in only two places in Iitate, a village about 25 miles (40 kilometers) from the Fukushima Dai-ichi nudear complex. ... Fukushima, home to the radiation-leaking plant, was the nation's fourth-largest rice producing prefecture (state) last year. .... but cesium is a concern because it can build up in the body and high levels are thought to be a risk for various cancers.
