Fukushima-1. Withdrawal of fuel and return of inhabitants


The withdrawal of fuel cores postponed for four years from the exploded reactor began. Meanwhile, the evacuated inhabitants urge to return to the thrown houses. Japan started extraction of unused fuel cores from the special pool on the third reactor of emergency Fukushima Plant-1. First of all will take seven fuel assemblies with the smallest risk of damage. In total in the reactor there are 566 fuel cores. The day before the city of Okuma located near the destroyed nuclear power plant was partially opened for people, having recognized about 40 percent of the territory as safe for accommodation, but the former inhabitants do not hurry to come back there yet. The correspondent.net tells details. Liquidation of Fukushima Plant-1 on March 11, 2011 in Japan there was the strongest earthquake in the history of the archipelago which caused the powerful tsunami which took away lives 18.5 thousand people. The brunt of the disaster damaged the NPP, the cooling system otlyuchitsya, nuclear fuel melted and burned protective building 1.2 and 3 of reactors, because of it occurred leak of hydrogen and he exploded. The fourth reactor suffered from explosion next. In total at Fukushima-1 six power units. As a result of accident nobody died. There were emissions of large volume of radioactive materials that led to infection of areas, adjacent to the station. 770 thousand of terabekkerely radiation - about 15 percent from leak level as a result of accident in Chernobyl were released into the atmosphere. The Japanese engineers-nuclear physicists counted explosion on Fukushima-1 that about 40 years for reduction of the NPP in a safe state will be required. Investigation by the cause of accident called actions of operating organization of Tokyo Electric Power and the public supervisory authorities which resulted in inability of the station to resist to natural disaster. At the end of 2012 the radiation level on the coast where there is Fukushima Plant-1, exceeded norm more than a hundred times. In general, nuclear pollution above norm was found in radius of 80 kilometers from the station. Growth of number of the people having cancer was recognized as insignificant, however the World Health Organization says that in the next 15 years the picture will worsen as in risk group there are people who at the time of accident were 20 years old. Last year the employee Fukushima-1 died from cancer. The financial damage, including costs of mitigation of consequences, costs of deactivation and compensations, is estimated approximately at 200 billion dollars. Every year this sum grows. The third Fukushima-1/Getty reactor In one and a half years after catastrophic accident, on August 13, 2012 the government of Japan officially began the procedure of refusal of atomic energy. Then Japanese relied on renewable energy carriers. Before accident on Fukushima nuclear power plants covered 30 percent of requirement Japan in the electric power and wanted to increase this indicator to 50 percent. The works on removal of all 1535 fuel cores from the pool of power unit number four were completed in 2014. Withdrawal of nuclear fuel from Wad Dra
