Shimane NPP Proceeding Steadily on Safety Measures toward Restart

In August, the Chugoku Electric Power Co., filed an application with the Nuclear Regulation Authority (NRA) of Japan to investigate the compatibility of the Shimane-3 (ABWR, 1,373MWe) with the country’s new regulatory standards. NRA has been making a similar examination at the power company’s Shimane-2 (BWR, 820MWe) since January 2014.

Prior to the filing, Shimane Prefecture had presented the power company with several conditions, including the following: (1) making earthquake and tsunami evaluations based on the latest knowledge, and adopting safety measures accordingly, (2) implementing severe accident measures after considering their effectiveness and impact, and (3) establishing disaster-relief measures in close cooperation with local governments. The prefecture agreed to the filing on August 9, with Chugoku Electric Power submitting its application the day after. Going forward, Atoms in Japan (AIJ) will report on the work on safety measures based on the new regulatory standards, as well as the latest progress at the Shimane-3.

NRA Allows Tokai-2 to Be Operated for Sixty Years, a First for a BWR

On November 7, Japan’s Nuclear Regulation Authority (NRA) issued the final approval needed to extend the operating lifetime of the Tokai-2 Nuclear Power Plant (BWR, 1100MWe) by an additional twenty years. The plan is owned and operated by the Japan Atomic Power Company (JAPC).

NRA has now approved lifetime extensions for three PWRs: the Takahama-1 and -2 NPPs and the Mihama-3 NPP, all owned and operated by the Kansai Electric Power Co. (Kansai EP). The Tokai-2 NPP is the first BWR in Japan to have its lifetime extended. As part of the NRA’s safety examination under the country’s new regulatory standards, approval of revisions to the operational safety program came twenty days before expiration of the forty-year operational limit for the Tokai-2 NPP. All the legal requirements have now been met for restarting for Tokai-2, following the permission given in September 2018 to make changes to the reactor installation (i.e., the basic design approval), and the approval granted in October 2018 for the work plan (i.e., the detailed design approval). JAPC said that...more
