The Nuclear Regulatory Commission is in a position to manage the serious deficiencies in anti-terrorism measures that were revealed one after another at the Kashiwazaki-Kariwa Nuclear Power Station of Tokyo Electric Power Company in Niigata Prefecture due to insufficient maintenance of nuclear material protection equipment. We have compiled an interim report stating that there were problems with the efforts at that time, such as the fact that humans had few opportunities to witness the site.
On the 27th, the NRA received an interim report from the Nuclear Regulatory Agency, which is inspecting TEPCO's recurrence prevention measures against the serious deficiencies in the countermeasures against terrorism that occurred one after another at the Kashiwazaki-Kariwa nuclear power plant.
Among these, the deficiencies that occurred one after another at the Kashiwazaki-Kariwa Nuclear Power Plant were that the maintenance and management of nuclear material protection equipment was inadequate compared to other nuclear power plants, and the people in the management position did not participate in the discussion of troubleshooting and the site. He said that there was a problem with the efforts at that time, such as the fact that he was less likely to attend.
On the other hand, the cost reductions that TEPCO has been working on after the Fukushima Daiichi nuclear accident could not be said to be a company-wide problem, saying that there was no evidence of debate that would lead to inadequate anti-terrorism measures.
In response to this interim report, Chairman Toyoshi Fuketa said, "Even though TEPCO, the party involved in the nuclear accident, has a stronger sense of tension and a sense of crisis than anywhere else, it is natural, but it is managed by turning its attention to the protection of nuclear material at the Kashiwazaki Kariwa nuclear power plant. I don't know if it was done. I would like TEPCO to show the policy whether the equipment guarantees the protective power even if the culture and attitude are deteriorated. "
After approving this interim report, the Regulatory Commission has issued a corrective action order to TEPCO in April last year to ban the movement of nuclear fuel in order to lift the harsh natural environment such as snow peculiar to the Kashiwazaki Kariwa nuclear power plant. We decided to focus on future inspections, saying that eight items are necessary, such as the implementation of equipment that can prevent intrusion and the drastic review of the system for dealing with troubles.
