Catastrophe at the plant "Fukushima-1" was preceded by a massive earthquake and the ensuing tsunami. At the epicenter of the quake was magnitude aftershocks 9-9,1 points. The earthquake was the most of strongest in the history of the Land of the Rising Sun. The victims of this natural disaster were about 18 thousand people, and the economic damage from it exceeded $ 300 billion. bucks. Specifically on the nuclear power plant "Fukushima-1" as a result of melting of fuel assemblies in the atmosphere has got a significant amount of radiation. The station decided to retire, it was formed around the 30-km exclusion zone from which evacuated more than 80,000 people. It is expected that the elimination of the consequences of the tragedy and the withdrawal from service station will be about 30 years old.
In late June 2012, the shareholders of Tokyo Electric Power Company approved the allocation of financial assistance in the amount of $ 1 trillion. yen (about 12.6 billion. dollars) to eliminate the effects of a nuclear disaster. The total amount of allocated funds that had been provided by the Government of the Land of the Rising Sun since the tragedy, was 3.5 trillion. yen (about 44.1 billion. dollars).
Specifically, at the time of the earthquake on 3 operating power stations were shut down the emergency protection of the station, which worked normally. With all of this in an hour at the station was completely interrupted power supply (including replacement of diesel power plants). Presumably this was a prerequisite for a strong tsunami that followed the earthquake directly. The tsunami in finding the station could be up to 15 meters.
Electricity supply is a prerequisite for decay heat removal reactors. Immediately after the loss of spare diesel power plants operator station TEPCO said the Japanese government of an emergency situation that prevailed at the plant. From now on the ground station, work began to address the impact of the tragedy, which has focused on solving the problem of emergency power supply systems. To do this, at the plant, it was decided to deliver mobile power plants that were to change a defective diesel units.
At first glance, the basic premise of the catastrophe may seem sudden massive earthquake with the tsunami disaster, as the equipment out of service. If we talk in a different way, the technical problems at the plant as a result of a severe natural disaster. But not far considering the events of the tragedy found that far not the last role in a hell of developments in the nuclear power plant "Fukushima-1" played by human factor, and objectives of the organization of emergency work in an emergency. According to the conclusions of the Japanese parliament perpetrators of the tragedy that occurred at the station are: Tokyo Electric Power Company, the country's authorities and the Japanese mind. And if you make a complaint to the mentality is quite problematic, because this concept is not defined, then the holder of the station and to the government to show them completely can be.
The report of the Federal Inspectorate for Nuclear Safety of Switzerland stressed that plant staff at the time of the tragedy at the station did not always have access to the correct disk imaging on the actual condition of the equipment and the appearance of those or other problems, which in turn led to an incorrect assessment of the situation on the ground and making the wrong solutions. When all this is the first mistake, apparently, was made immediately after the first quake, when the Japanese Meteorological Service has announced a warning about the likelihood of a tsunami with waves up to 3 meters. This signal excitement, which, as it turned out, could not foresee all the scale only the natural disaster at the plant was abandoned without pay tribute to the attention of the safety control services. Apparently, they have not taken any action tribute to the risks posed by the tsunami, which was a mistake that resulted in the irreparable consequences.
Analysis of professionals has shown that human factor played a major role not only in the prevention of ill-fated time option, and in the forthcoming strategy selection, in order to take hold of the situation. According to one of the hypothetical circumstances of deteriorating station, experts of the Federal Security Service of the Swiss dubbed shortage of staff. At the moment immediately when several reactors "Fukushima-1" out of the system, remaining on the staff station in the physical layer are not able to solve the problems which appear immediately stations at various locations. All this, coupled with the lack of accurate behavioral strategies that appears in the disaster, as rassredotachivaniya obligations only led to more confusion at the plant.
According to the views of Japanese parliamentarians and workers of TEPCO and government officials failed conventional Japanese mind, which is admired in Russia and in the world. According to the views of the Japanese members, this tragedy was "made in Japan", and its roots are to be found in Japanese culture. Because the people of the country of the rising sun is quite obedient, faithful adhere to this applets and not subjected to acts of the authorities in question.
The Commission, which included 10 people, was created in December 2011 and in the intervening period of time could make a huge amount of work. Headed the committee Dr. Yotaro Hatamury from the Tokyo Institute. In the work on drafting the final report, the Commission used the questionnaires and surveys actually 13 thousand people, including 1,100 people from the former management of the operating company TEPCO stations and control of the country. On this commission members izderzhali 900 hours. Besides the parliamentary committee investigated and nearby to "Fukushima" nuclear power plants that were eventually affected by the tsunami less damage.
The deputies found out that neither the municipal regulatory authorities nor employees of TEPCO, had not even considered as a possible tsunami version of a nuclear catastrophe. The report said that the management of energy companies and the government acted properly, keeping bad decisions on the part of each other, instead of the order to loaf about the competence of those people who perceive these decisions.
With all of this the last 2 investigation into the circumstances of the disaster lay all the blame for what has happened to natural disasters, deciding that tsunami was so strong that station, as if she was not well fortified, simply could not withstand the pressure of the elements. At the current time, experts believe that TEPCO and the government land of the rising sun is not only not prepared for the probable natural disasters, and did not consider it necessary to speak about the damage rector number 1 during the first tremors. Criticized and activities of former Prime Minister Naoto Kahn, who did not trust the Tokyo Electric Power Company and constantly interfered in the process of eliminating the consequences of the tragedy at the station, requiring further elaboration and reports. According to experts the commission, its involvement in the process "caused chaos in the system of management and staff teams."
As a result of the tragedy at the nuclear power plant "Fukushima-1", which began on March 11, 2011, the station completely melted fuel rods at once at 3 reactors. Vast areas of the country of the rising sun were subjected to radioactive contamination. At the current time, all power units have already been warped into a state of cool stops are the preliminary work on the extraction of their nuclear fuel. According to the plans of the company TEPCO, with the passage of time over the curled and blocks seem to be protective concrete sarcophagus that will prevent the release of radiation into the atmosphere.
