It has been 15 years since the Niigata Chuetsu-oki Earthquake 16 days ago.
At the TEPCO Kashiwazaki Kariwa Nuclear Power Station, which has been out of operation for a long time after the earthquake and the accident at the Fukushima Daiichi Nuclear Power Station, one-third of the operators have no experience in operating the nuclear power plant. Improvement of technology is an issue.
At the Kashiwazaki-Kariwa Nuclear Power Plant in Niigata Prefecture, due to the impact of the Niigata Chuetsu-oki Earthquake, which observed a maximum seismic intensity of 6 upper, there was damage such as a fire in the transformer. I can no longer drive.
After that, some reactors resumed operation, but the accident at the Fukushima Daiichi nuclear power plant occurred in 2011, and all reactors have been shut down.
According to TEPCO, the Kashiwazaki-Kariwa Nuclear Power Plant has been out of operation for a long period of time, and of the 266 operators, 97, or 36% of the total, have no experience in operating the nuclear power plant.
For this reason, TEPCO has dispatched operators to nuclear power plants of other electric power companies for training, etc. in order to develop human resources, but due to the spread of the new coronavirus infection, it has been canceled for the past two years. about it.
Furthermore, due to the effects of a series of inadequate counter-terrorism measures, the procedure for restarting Unit 7 was in progress, and there is no prospect of restarting, so improving the skills of operators is an issue.
