Japan concluded the cause of the accident in Fukushima

The lack of preparation and failure to respond to incidents is the cause of the nuclear crisis in Fukushima.

The Japanese government team announced the cause of the nuclear crisis at the Fukushima plant. According to them, the plant management and operation agency did not adequately prevent options to deal with the tsunami and its consequences.

AFP quoted the report as saying, not to point out the shortcomings to blame each other but to find out how the incident took place.

Written report, Tokyo Electric Power Company (TEPCO), the plant's governing body, as well as the authorities "did not prepare options to deal with situations caused by one or more tsunamis. ".

TEPCO has failed to "combine measures other than the basic design to deal with tsunamis. This is a limitation of plant safety assurance , " the report said.

In addition, Japan 's nuclear agency "does not require TEPCO to take concrete measures such as building more works after receiving similar results from TEPCO in 2008 and in early 2011 about The impact of tsunamis on their factory buildings. "

In contrast, TEPCO said in its report that no countermeasures could be taken against the 9-magnitude earthquake and huge waves of waves hit the factory.

The government report said the situation was worsened by the following reasons: delays in information disclosure, managers lacked knowledge in the process of responding to emergency situations and communication between the parties are not good, including information between factory employees and the government, among employees and between government agencies.

Collecting accurate and timely information is a prerequisite for making the right decisions to resolve the problem. Information gathering as well as providing information is very important, the report said.

The report also pointed out that TEPCO employees are not trained to deal with emergencies such as shutting down the system when tsunamis fails to prevent backup mechanisms, and employees also misunderstand the problems. came out with the cooling system at the No.1 and No. 3 reactors, AP quoted the report as saying.

The 500-page report is gathered from the opinions of 450 experts, including government officials and factory employees led by research team members, Yotaro Hatamura, a professor at the university. Tokyo, specializing in research on the causes of published incidents.

The research group, founded by Japanese Prime Minister Nato Kan in May, made preliminary conclusions and is expected to draw a final conclusion on the cause of the incident in mid-2012.

In a report submitted to the United Nations nuclear watchdog earlier, the Japanese government acknowledged the lack of preparation for nuclear incidents at the Fukushima plant.

The six reactors of the Fukushima I nuclear plant were damaged by the earthquake and tsunami, with explosions at four reactors after the cooling system was paralyzed. Last week, authorities announced the plant had reached a steady state but would take decades to completely disable it.

More than 20,000 people died because of the earthquake and tsunami. More than 10,000 people have to evacuate when radioactive materials from nuclear power plants leak to the soil, sea and air.
