TEPCO president fell sick amid troubles at its nuke plantTOKYO, March 27, KyodoMasataka Shimizu, president of Tokyo Electric Power Co., which operates the crisis-hit Fukushima nuclear plant, fell sick March 16 and took some days off from the liaison office between the government and the utility firm, TEPCO officials said Sunday.While Shimizu was away from the office set up at the firm's headquarters, he collected information and issued instructions from a different room of the headquarters building to address the troubles at the Fukushima Daiichi nuclear power station hit by the March 11 quake and subsequent tsunami, the officials said. He has already recovered and come back to work at the liaison office, they said.A TEPCO spokesperson declined to elaborate on his health condition, but said he did not fall over or need to be hooked up to an intravenous drip.Shimizu has not appeared in public since attending a press conference on March 13, two days after the catastrophe that wreaked havoc on northeastern and eastern Japan.==Kyodo

Dobro, Yoyogi, ne komentarises vest da im curi plutonijum na sve strane... vazno je da si utripovao da je francuski ministar slagao (a nije!).Ili je i dalje sve pod kontrolom? Hoces li ostati medju poslednjima, ostaviti svoje dete, da bi dokazao da su Japanci uberturbomegadojaja nacija i da im niko nista ne moze, pa ni nuklearne havarije?
Nista ne curi, taman posla na sve strane, ne mrdam malim prstom.

Kako to mislis, braco, "curi na sve strane". To je veoma tezak metal i nije mobilan. Prema saopstenju kompanije, sadrzaj Pu nadjen u zemljistu ispod NE Fukushima Daiichi nije opasan po ljudsko zdravlje i slican je onom koji je padao na Japan posle nuklearnih proba koje su izvodjene od strane svetskih sila ranijih decenija.

Meni je jako jako zanimljivo da se u izvestajima o nesreci u Fukushimi zapadni mediji veoma cesto okrecu, manje ili vise suptilno, prici o japanskim kulturnim specificnostima, a da niko nije pricao o americkim i britanskim kulturnim specificnostima posle (za sada neuporedivo, ne za decimalu nego za celu algebru opasnijeg) BP akcidenta.

Plutonijum je nesporno detektovan oko elektrane. Nema kako drugacije da izadje nego da procuri. Jedna je stvar ako je iscureo u okviru kontaminirane vode kojom se hlade reaktori, a drugo je ako curi iz ostecenih sipki. Za sada to nije nista strasno, sva je prilika i da ce da ostane pod nekom relativnom kontrolom, uprkos tome sto je tamo haos. Part-time evakuacije, part-time uzbune, part-time sugestije o nekoriscenju vode...

Okej, dosli smo dovde od "curenja na sve strane", sto je onako prilicno uobicajena FUD formulacija, kakvih smo se nacitali zadnjih nedelja.

Plutonium detected in soil at Fukushima nuke plantTOKYO (Kyodo) -- Plutonium has been detected in soil at five locations at the crippled Fukushima Daiichi atomic power plant, Tokyo Electric Power Co. said Monday, adding to woes over radiation contamination in the country's worst nuclear crisis.The operator of the six-reactor complex said that the plutonium, the presence of which was confirmed for the first time in the ongoing nuclear emergency, could have been discharged from nuclear fuel at the plant hit by the devastating March 11 earthquake and tsunami, but does not pose a major risk to human health.Plutonium is more toxic than other radioactive substances such as iodine and cesium, but the levels confirmed from soil samples taken at the plant on March 21 and 22 were almost the same as those from the fallout detected in Japan following past nuclear tests by the United States and Russia, said the utility known as TEPCO.The government's Nuclear and Industrial Safety Agency said it remains unknown which reactor plutonium came from and that TEPCO and the science ministry will strengthen monitoring on the environment both in the plant and outside of a 20-kilometer exclusion zone set by the government.Hidehiko Nishiyama, a spokesman for the nuclear regulatory body, said the detection of plutonium suggests "certain damage to fuel rods" and said it is "deplorable" that the toxic radioactive material was found despite various containment functions at the reactors.Meanwhile, TEPCO and the agency said Monday that high levels of radiation exceeding 1,000 millisieverts per hour were spotted Sunday in water in a trench outside the No. 2 reactor's building at the nuclear plant. They said the contaminated water is suspected to have come from the reactor's core, where fuel rods have partially melted.The agency said TEPCO is expected to pump out similarly highly radioactive water that has been building up in the basement of the No. 2 reactor's turbine building, which is connected to the trench, in a bid to eventually remove the water.TEPCO has found the concentration of radioactive substances in a pool at the No. 2 reactor's basement was 100,000 times higher than usual for water in a reactor core.The company added the radiation level in the air in the trench stood at 100 to 300 millisieverts.At a radiation level of 1,000 millisieverts per hour, people could suffer a decrease in the number of lymphocytes -- a type of white blood cell -- in just 30 minutes, and half could die within 30 days by remaining in such conditions for four hours.Although it remains unknown whether the contaminated water has flowed into the sea from the trench that is 55 meters away from the shore, TEPCO suspects the high concentration of radioactive substances found in seawater near the plant reactors' drainage outlets may be linked to the trench water.Earlier Monday, the nuclear agency said radioactive iodine-131 at a concentration 1,150 times the maximum allowable level was detected Sunday in a seawater sample taken around 1.5 kilometers north of the drainage outlets of the troubled Nos. 1-4 reactors.Haruki Madarame, chairman of the Nuclear Safety Commission of Japan, a government panel, told reporters he is "very worried" about the high-level radiation found in water in the trench, which is outside the radiation-controlled area set by TEPCO.Maradame said he cannot predict when the ongoing nuclear emergency will end and pointed to the possibility that fuel rods in the No. 2 reactor, which were temporarily exposed to the atmosphere, have been significantly damaged."We must control the water well so it won't ever go outside" the complex, said Sakae Muto, vice president of TEPCO, at a news conference.On Monday, TEPCO continued to remove highly radioactive water from inside reactor buildings at the crisis-hit plant, in an effort to enable engineers to restore the power station's crippled cooling functions. The turbine buildings are equipped with electric equipment necessary to cool down the reactors.Nishiyama denied the possibility that the No. 2 reactor's vessel has cracks or holes, saying there is no data to suggest this. It is rather likely that radioactive water has leaked from pipes or valves, he said.He said it is now necessary to strike a balance between two missions -- injecting coolant water into the reactor cores and spent nuclear fuel pools to prevent them from overheating, and removing radioactive water in the turbine buildings and trenches.The spokesman said the water contamination may have been caused by operations to pour massive amounts of coolant water into the reactors and pools.
malo previse "unknown" i "cannot predict" za moj ukus

Pa i curi na sve strane, samo sto to nije traumaticno kao sto zvuci. Tezak metal koji ne stupa tek tako u jedinjenja. Ne moze to curenje da dovede do humanitarne katastrofe, ali da ce da bude dodatni problem prilikom sanacije havarije, to hoce.

Od pre neki dan, ali da se podsetimo s kim imamo posla :

Japanese Nuclear Plant Operator Plagued by ScandalFor years, Tepco, the operator of the Fukushima power plant, has been widely criticized for deadly accidents and improper inspections. The Fukushima disaster is the tragic nadir in a history of poor management at the company's nuclear facilities.InfoIt must have been a difficult day for Tsunehisa Katsumata. In 2003, the then-president of the Tokyo Electric Power Company, or Tepco, gave a speech addressing what, until then, had been the biggest scandal in the history of Japan's largest energy utility company. In 29 incidents the year before, nuclear power plant maintenance documents had been falsified and Tepco had been forced to take 17 nuclear reactors temporarily offline as a result. Tepco CEO Hiroshi Araki and four other top executives resigned.In unflinching words, Katsumata took his company to task for its shortcomings and announced no less than a new corporate culture, one with a strict code of ethics and a policy of open and honest communication with the public. Today, though, those words must ring hollow to the people who have received high levels of radiation following the accident at the Fukushima I power plant, and to those who have been evacuated and may never be able to return to their homes located near the plant again.The tone of Katsumata's speech was clear: The numerous past incidents were in no way isolated mistakes made by individual employees. Instead, they were the result of a corporate culture at Tepco that had allowed hair-raising breaches in safety to occur.A Nuclear Division Spins out of Control"First, we must admit that we had no clear rules to judge whether equipment was fit for service," Katsumata states in his speech, which is still available on Tepco's website today. He said that there were no rules addressing the fact that machinery and equipment generally wear away or crack with the passage of time, so equipment was used as long as such flaws didn't pose "safety hazards."And therein lies the problem: When something was unclear, Tepco engineers apparently made arbitrary decisions. "They repeatedly made personal decisions based on their own idea of safety," Katsumata said. But it is clear that those ideas of safety weren't stringent enough. "Nuclear division members tended to regard a stable supply of electricity as the ultimate objective," he said.Over time, the nuclear division appeared to spin out of control, according to Katsumata's assessment. "The engineers were so confident in their knowledge of nuclear power that they came to hold the erroneous belief that they would not have to report problems to the national government as long as safety was maintained," he said. In the end, "they went as far as to delete factual data and falsify inspection and repair records."He also attributed another dangerous trait to the engineers. The high degree of technical specialization required in nuclear power generation, he warned, had "hampered flexible personnel changes in the nuclear power division, and as a result, this division became a homogeneous and exclusive circle of engineers who defied checks by other divisions, including the management."The 2004 manuscript is only one testament to the nuclear power giant's troubled approach to crisis management. Both before and after the speech, an impressive list of incidents continued to grow, including deadly accidents. During the 1980s and 1990s, in several instances Tepco falsified data in voluntary inspections, including the number of cracks in the reactor pressure vessels. In 1991 and 1992, the safety vessel of Reactor 1 at the Fukushima plant, which had gone online in 1971, was tested for leaks. According to Tepco, workers pumped air into the safety vessel in order to reduce the rate of leaks. In 2000, a reactor at the Fukushima nuclear plant had to be shut down because of a hole in a fuel rod. Similar incidents had already occurred in 1997 and 1994 in which radiation had been released. In 2002, cracks in water pipes were discovered at the nuclear power plant. In 2002, an engineer with the US firm General Electric, which manufactured three of the six reactors at the Fukushima Daiichi nuclear power plant, also raised the alarm bell. Inspeactions had not been carried out at a total of 13 reactors at Tepco power plants. He showed the Japanese nuclear regulatory authority 29 instances of falsified data and cover-ups, a development that led to the resignations in 2002 of top Tepco executives. In 2006, radioactive steam leaked from a pipe at the Fukushima plant. The company was also accused the same year of falsifying data about coolant water temperatures in 1985 and 1988. The data had then been used during mandatory inspections of the plant in 2005. In 2007, further falsified reactor data from Tepco emerged. In 2007, at least eight people died when the Kashiwazaki-Kariwa nuclear power plant was badly damaged in an earthquake. Pipes burst, fire broke out and radioactive water leaked from a spent fuel pool. Tepco had to decontaminate the affected building. The nuclear power plant remained closed for one year so earthquake safety -- which had allegedly already been good enough -- could be improved. Later it was determined that Tepco had missed 117 inspections at the site. In March 2009, another fire broke out at the Kashiwazaki-Kariwa plant, resulting in one employee injury. On March 2, 2011, just days before the start of the current earthquake catastrophe, Japan's nuclear regulators lobbed accusations of mass negligence against Tepco. It alleged that Tepco had failed to inspect 33 pieces of equipment at the Fukushima-Daiichi plant, one of the sites of the current catastrophe, including central cooling system elements in the six reactors, and spent fuel pools that hadn't been inspected according to regulations. The company has since admitted to having made the errors. At the same time, Tepco also reported to the nuclear regulatory authority that it had not only failed to do the 33 inspections at the Fukushima-Daiichi plant, but also 19 further inspections at the nearby Fukushima-Daini plant. Some experts had already been warning since the 1970s that the Mark 1 reactor type, produced by US manufacturer General Electric and also called the "Fukushima design," was not constructed to survive a combination of an earthquake and tsunami. Only days after the earthquake, two engineers who helped build the plant confirmed at a press conference that serious construction errors had been made. Many backup systems for emergencies had not been built at the plant.'What is Going on Here?'Looking at the situation today, statements made by Tepco spokesman Hiroyuki Kuroda in March 2004 seem bitterly ironic. He pledged that Tepco had "learned numerous valuable lessons" from the 2002 scandal. "One of the most important was that information should always be shared," he said.But the company's approach to public information seemed to be precisely the opposite during the past two years. Just as it had in previous years, Tepco appears to have reported to the Japanese government only those things it was unable to keep secret. It was only when the shell of one of the reactor buildings exploded live on television on March 12 that the world became aware of the true extent of the accident.As a result, five days after the tsunami, Japanese Prime Minister Naoto Kan himself visited executives at Tepco headquarters and shouted at flabbergasted engineers: "What is going on here?" He reportedly accused the Tepco officials of placing the well-being of their own company above that of the Japanese people."It is not a matter of whether Tepco collapses, it is a matter of whether Japan goes wrong," he is reported to have said. Afterwards, Kan named himself the head of a crisis team made up of government and Tepco officials.Critics Claim Tepco Did More to Save Plant than Ensure SafetyBy doing so, he may have helped prevent even worse things from happening because the attitude that seems to have permeated Tepco -- namely that the company and its property should be given the greatest priority -- appears to remain in place, even in the face of a nuclear catastrophe. The engineers reportedly considered pumping ocean water mixed with boric acid into the damaged Reactor 1 as early as the morning of March 12 in order to prevent a threatening total core meltdown.The problem was that the action would have been equivalent to abandoning the reactor altogether because the salt water would have caused damage that could have permanently destroyed the plant. The engineers waited for hours before they finally begin pumping sea water at 8:20 p.m. local time into the reactor. A Tepco spokesman said the company had waited until the right time, taking into account the security of the entire facility.Critics, however, hold another view. Tepco "hesitated because it tried to protect its assets," Akira Omoto, a former Tepco executive and a member of the Japan Atomic Energy Commission, told the Wall Street Journal. Another government official, speaking on the condition of anonymity, told the newspaper: "This disaster is 60 percent man-made. They failed in their initial response. It's like Tepco dropped and lost a 100 yen coin while trying to pick up a 10 yen coin."
