Nuclear Facilities

Licensing status for the Japanese nuclear facilities

The new safety regulation was estabished in 2013 to include the TEPCO Fukushima Daiichi NPP accident lessons learned and opinions/proposals from inside and outside of Japan. Each utility's reactor installation and operation are to be evaluated in accordance with this regulation.

Currently, multiple NPPs and other nuclear facilities, e.g. fuel cycle facilities are undergoing a safety review conducted by the Nuclear Regulation Authority (NRA).

The review mainly targets three items submitted by respective utilities, which is 1) change in reactor installation, 2) construction plan and 3) operational safety programs, and the following chart shows the progress of the NRA review on reactor installation change.
