Overseas Network, May 24. According to the Japanese media "Fukushima Minyou" on the 24th, Japan's Tokyo Electric Power Company (Tepco) announced on the 23rd that it has conducted a review on the safety of the Gner container (wrapping the reactor) inside Unit 1 of the Fukushima Nuclear Power Plant. shell), it was found that part of the foundation concrete supporting the reactor pressure vessel was damaged and the steel bars inside were exposed.
Tepco said it may be caused by the heating of the fuel dissolved.

TEPCO said that this is the first time that the foundation damage of Units 1 to 4 of the Fukushima nuclear power plant has occurred.
In addition, multiple white lumps were found directly under the pressure vessel of the nuclear reactor of Unit 1.
TEPCO believes that if there is major damage to the foundation, the pressure vessel is likely to fall.
In order to investigate the situation of Unit 1 of the Fukushima Daiichi Nuclear Power Plant, TEPCO deployed an underwater robot to inspect the inside of the reactor containment of Unit 1 in February 2022.
The robot filmed that there may be "nuclear debris" and sediment in the containment.
In March, the robot was damaged by water while it was working, which interrupted the investigation.
Some media pointed out that since the serious nuclear leakage accident at the Fukushima Daiichi nuclear power plant in 2011, the Japanese government and TEPCO have taken insufficient measures to deal with the nuclear accident and have many loopholes.
