Regarding the safety measures work for Kashiwazaki-Kariwa Nuclear Power Station Unit 7 in Niigata Prefecture, TEPCO has announced that the fire protection work for a facility called the "waste treatment building" has not been completed.
This is the fourth case in which unfinished construction was found in the safety measures for Unit 7, which was announced to have been completed in January, and TEPCO is investigating further.
It was newly found that the construction was not completed at the shared facility of Units 6 and 7 of the Kashiwazaki-Kariwa Nuclear Power Plant, and the fire protection of the "waste treatment building" that has equipment to treat waste liquid containing radioactive substances. It is construction.
On the 3rd basement floor of the building, there is a part where pipes penetrate the wall, and in this part, new construction was required to prevent the fire from spreading based on the national regulatory standards.
However, according to TEPCO, it seems that the department in charge within the company could not share the fact that construction was necessary.
Regarding the safety measures for Unit 7, which TEPCO is aiming to restart, after it was announced that the construction was completed in January, the actual construction was actually carried out due to some of the water stoppage work related to the reactor cooling system. It turns out that it was not over, and this is the fourth case.
TEPCO said, "We apologize for causing concern to the local people. We will continue to carry out a comprehensive inspection to confirm the existence of unfinished safety measures, and we will inform you of the inspection status again." I will.
