Fukushima Daiichi Nuclear Power Plant Off-site Center dismantled Fukushima Okuma-cho, September 10, 17:20

In the event of an accident at the TEPCO Fukushima Daiichi NPS, the “off-site center” in Fukushima Prefecture was abandoned four days after the accident due to inadequate protective measures against radioactive materials, even though it was the headquarters that took measures locally The demolition work of "" began on the 10th.

The Off-Site Center is a country that allows people involved in the site to gather information and evacuate smoothly when an accident occurs at a nuclear facility based on a lesson learned from a critical accident in Tokai Village, Ibaraki Prefecture 20 years ago. Etc. were installed nationwide.

The “Off-site Center” in Okuma-cho, Fukushima Prefecture started operation in 2002, and the national emergency headquarters was established in the nuclear accident eight and a half years ago.

However, the emergency generator was not used, and the protective measures to prevent the entry of radioactive materials were insufficient, the radiation dose in the room increased, and the function that was originally expected to be abandoned four days after the accident. I couldn't do it.

About this facility, Fukushima Prefecture decided to dismantle because of the establishment of a new off-site center and the request for residential land development from the local community, and work began on the 10th.

From the reinforced concrete 2-story building, the desks and chairs that were left at that time were carried away.

Demolition is scheduled to end next March.

Fukushima Prefecture will transfer precious materials such as whiteboards describing the response status at the time to the “Great East Japan Earthquake and Nuclear Disaster Relegation Hall” under construction, and will share lessons learned, but researchers will leave the buildings. There is also an opinion that asks for this, and it seems that it will become a debate about how to convey the lessons of the nuclear accident after this dismantling.

Offsite center during the Great East Japan Earthquake

The off-site center in Okuma-cho, Fukushima Prefecture is a facility where the country establishes a local response headquarters when a problem occurs at the Fukushima Daiichi nuclear power plant and the neighboring Fukushima Daiichi nuclear power plant in the same town. Operation began in 2002.

However, the accident that caused a large amount of radioactive material to be released at this facility, which was set up at a very close distance of only 5 km from the nuclear power plant, was “unexpected”.

Immediately after the accident, the emergency generator could not be used, and the power outage continued until dawn on March 12. In addition, it was difficult to contact local governments without communication lines.

In addition, it was a harsh environment where only a few days were prepared for the staff who gathered the stored food, and no nap room was secured in the building.

In addition, the air conditioner does not have a filter for blocking radioactive materials, and the room is high enough to reach 1 millisievert in less than half a day, which can be exposed to ordinary people for a year. It was a quantity.

As a result, the staff who responded were forced to withdraw to the prefectural office in Fukushima City, about 60 km away, just four days after the accident.

Nuclear power plant accidents

How will we inherit the lessons of the nuclear accident?

Fukushima Prefecture will collect and utilize materials from that time.

Since December last year, experts from Fukushima University, commissioned by Fukushima Prefecture, have collected 234 items, including a whiteboard that shows the status of their response at the off-site center in Okuma.

It will be exhibited at the “Great East Japan Earthquake and Nuclear Disaster Museum” under construction in the neighboring Futaba Town.

NHK entered the off-site center with permission from Fukushima Prefecture four days before the dismantling began.

In addition to chairs and desks, there were still copy machines and telephones used for accidents, and blankets that were thought to have been used for nap in the room. .

However, depending on the prefecture and town, there was no place for discussion about leaving the building itself as an “earthquake ruin” because the residents did not hear from them.

The question of how to work to prevent weathering of important lessons has been re-examined after the dismantling of the off-site center.

Mr. Junichi Yonera, the Fukushima Nuclear Safety Measures Division, said, “There are parts of the country and prefectures that were not supposed to be anticipated. I will go. "
