A210 Research Committee on Chuetsu-Oki Earthquake influences of Kashiwazaki-Kariwa Nuclear Power Station : (2) A Report on the Survey of Kashiwazaki-Kariwa Nuclear Power Station

Abstract

Due to the Niigataken Chuetsu-oki earthquake on 16 July 2007, Tokyo Electric Power Company's Kashiwazaki-Kariwa Nuclear Power Plant (NPP) suffered from quakes exceeding design basis. The plants consisting of seven reactors and related facilities performed its essential functions required in the nuclear safety design such as "stop", "cool", and "confine" as designed, no matter whether in operation or in outage. The fact our group found through surveys in the site tells us that the experience of the Kashiwazaki-Kariwa NPP provides all NPPs with very important scientific findings.
