Regarding Tsuruga Nuclear Power Station Unit 2 in Fukui Prefecture, the Nuclear Regulatory Commission pointed out that it is inappropriate to delete some of the data submitted by Japan Atomic Power Company in the past and overwrite it, and to describe only the latest survey results. Japan Atomic Power Company has revealed that it has been overwriting repeatedly five years before the start of document creation.
The overwritten data is a part of the observation results shown in the past among the materials related to the fault passing directly under Tsuruga Nuclear Power Plant Unit 2, and Japan Atomic Power Company explained the circumstances on the 19th.
In this, he explained, "At that time, I thought that it was a document and I knew that I could modify it and present it." If new survey results are obtained, it is okay to delete the data shown in the past. Judging, it was clarified that overwriting has been repeated since 2016 when the material creation was started.
The NRA, the secretariat, commented one after another, saying, "The reliability of Japan Atomic Power Company in the examination was destroyed by overwriting" and "Did you recognize that you made an important decision?"
A series of actions by Japan Atomic Power Company is expected to be discussed at a regular meeting of the Regulatory Commission next week.
Regarding Tsuruga Nuclear Power Plant Unit 2, six years ago, at an expert meeting of the Regulatory Commission, it was pointed out that "the fault that passes directly under the reactor may move in the future," and Japan Atomic Power Company argued. The deliberation follows parallel lines.
