There is no problem with the other emergency generators… Operator’s cause investigation policy
It was reported that one of the emergency generators at the Shika Nuclear Power Plant, located in an area damaged by a strong earthquake on the Noto Peninsula, automatically shut down during test operation on the 17th.
According to the Yomiuri Shimbun and local public broadcaster NHK on the 18th, Hokuriku Electric Power Company, the operator of the Shika Nuclear Power Plant located in Shikamachi, Ishikawa Prefecture, said that one emergency diesel generator for Unit 1 of the Shika Nuclear Power Plant was in operation from around 5 p.m. on the 17th. announced that it had started.
However, this generator automatically shut off 15 minutes after starting operation.
This test run was conducted to check if there were any problems as an earthquake of about 5 magnitude occurred in Shikamachi on the 16th. It took 80 minutes for each emergency generator. There was no problem with other emergency generators.
The Japan Meteorological Agency divides earthquake shaking into 10 levels: intensity 0, intensity 1, intensity 2, intensity 3, intensity 4, intensity 5, intensity 5, intensity 6, intensity 6, and intensity 7. Jindo 0 is the lowest level.
A seismic intensity of about 5 is an earthquake at a level that makes most people feel scared and want to grab something. In some cases, desks, dishes, books, etc. may fall. In some cases, furniture that is not fixed may move and become unstable, shaking to the point of falling over.
Hokuriku Electric Power Company announced that it would investigate the cause of the automatic shutdown of emergency generators.
Sika Nuclear Power Plant cannot use some of the electricity received from outside due to the impact of the earthquake. Hokuriku Electric Power Company explained that it has secured power sources that are important for safety in that it has multiple emergency generators.
However, when a magnitude 7.6 earthquake occurred at the Sika Nuclear Power Plant on the 1st, the transformer piping of Units 1 and 2 of the nuclear power plant was damaged. A total of 23,000 liters of oil was leaked.
Hokuriku Electric Power Company announced that it had recovered most of the oil, but during repeated checks on the 7th, it discovered an oil slick about 10 meters wide and 5 meters long above sea level.
