Insufficient anti-terrorism measures at TEPCO Fukushima Daini Nuclear Power Plant

The Nuclear Regulatory Commission has taken measures against terrorism, such as finding some of the doors of the "protected area" where entry is restricted at TEPCO's Fukushima Daini Nuclear Power Station in Fukushima Prefecture, which is not properly managed. It was announced that there was a defect in.

It was set to the lightest level among the four grades related to the protection of nuclear materials, as measures have already been taken.

At the Kashiwazaki-Kariwa Nuclear Power Plant in Niigata Prefecture of TEPCO, problems related to terrorist countermeasures continued, such as the fact that multiple facilities for detecting the intrusion of terrorists were broken last year and it became clear that the subsequent countermeasures were not functioning sufficiently. The Regulatory Commission has imposed administrative sanctions on TEPCO and is also investigating other nuclear power plants for similar problems.

Among them, it was found that some doors in the "protected area" in the turbine building were not properly managed at TEPCO's Fukushima Daini Nuclear Power Plant Units 1 and 4 in Fukushima Prefecture. ..

This door seems to have existed since the beginning of the construction of the nuclear power plant.

The person in charge of nuclear material protection did not recognize that it needed to be managed, and the Regulatory Commission was unaware of the existence of the door.

It was also found that some of the entrances and exits of the protected areas of Units 1 to 4 were not fully inspected by metal detectors.

The Regulatory Commission said that the door was not directly connected to the outside and the entry was restricted, and that all deficiencies had already been taken, etc. , Both were judged to be the most minor levels.

In addition, on the 19th, it was reported that there was an opening in the ditch leading to the "peripheral protected area" at the Ikata nuclear power plant of Shikoku Electric Power Company.

Since Shikoku Electric Power has already closed the opening, the Regulatory Commission has set this as the lightest level in four stages.

Local mayor "Great impact on the townspeople"

Regarding the fact that the Fukushima Daini Nuclear Power Station was confirmed to be deficient in anti-terrorism measures, Yukihide Matsumoto, the mayor of Naraha Town, where the Daini Nuclear Power Station is located, said, "There was a problem with the Kashiwazaki Kariwa Power Station, and I was wondering. The infrastructure for the city is being improved, and while we are working on migration and settlement, the impact on the townspeople will be great. "

Sonouede, touch on the policy the government to release into the sea and treated water to the criteria below, including radioactive substances such as tritium, which continue to increase at the Fukushima Daiichi nuclear power plant in the prospect of the two years after the decision last month, in "TEPCO is happening repeatedly scandal Therefore, I feel that it will have an impact on various aspects. As a company that operates a nuclear power plant, it is necessary to drastically review the idea of ​​crisis management, and I would like you to work on a change in awareness. " Was

TEPCO "I apologize for giving you anxiety."

At the meeting on the 19th, Mr. Hitoshi Shinbo, General Manager of the Public Relations Department of TEPCO's Fukushima Daini Nuclear Power Station, said, "The series of incidents from the Kashiwazaki-Kariwa Nuclear Power Plant has given everyone great anxiety. We apologize for the inconvenience. "

On top of that, "I think all the staff members are aware of the importance of nuclear security, but not everyone understood at the same level how much they had to do in detail. Currently, it is a drastic effort to strengthen the protection of nuclear material. We are considering countermeasures, but we would like to work hard one by one to earn the trust of the local people. "

Chairman Fuketa "There is a lot of room for improvement in both businesses and regulatory agencies."

Regarding the fact that the TEPCO Fukushima Daini Nuclear Power Station also revealed deficiencies in anti-terrorism measures, Toyoshi Fuketa, chairman of the Nuclear Regulation Authority, said, "The nuclear material protection cases revealed today have been long-term. This has raised awareness of nuclear material protection at the Fukushima Daini Nuclear Power Station. Although measures have been taken, we would like to continue to look at the overall efforts for nuclear material protection. " ..

On top of that, "The difficulty of protecting nuclear materials is that some people, both the business operator and the regulatory agency, are paying close attention to this issue, and the number of people who may notice the issue may be limited. I would like to find out if there are any changes on the regulatory side. I think there is a lot of room for improvement on both sides. "
