Regarding the Tsuruga Nuclear Power Station Unit 2 in Fukui Prefecture, the fact that Japan Atomic Power Co., Ltd. deleted some past data from the fault data and recorded only the latest results would affect the evaluation, and it was deemed unsuitable. Due to the issue pointed out by the committee, Nippon Electric is taking measures such as submitting the deleted data again.
Regarding the Tsuruga Nuclear Power Station Unit 2 which is going to restart, Nippon Electric Power Co., Ltd. deleted some observation results shown in the past in the data of the boring survey on the fault passing directly under the nuclear power plant submitted to the Nuclear Regulation Authority this February. , Only the latest analysis result was described.
On the other hand, the Regulatory Commission has suspended the examination because the data cannot be compared and it affects the evaluation and is inappropriate.
Nihondenden explained to the regulatory committee on the 4th, and said that the deletion was not arbitrary, and decided to submit the deleted data again.
In addition, he explained measures to prevent recurrence, such as establishing a system to check whether the handling of data in the materials is appropriate from an objective standpoint. The Regulatory Commission is considering whether or not the response of Nippon Electric Power Company is appropriate.
Regarding the Tsuruga Nuclear Power Plant Unit 2, the focus is on whether or not the fault that passes beneath it will move in the future, but the examination has not been completed and the timing of restart will remain uncertain.
