川内原子力発電所の第1回安全性向上評価の概要について
概要
Sendai Nuclear Power Station is the first one in Japan whose units has restarted under new regulatory requirements after Fukushima-Daiichi Nuclear Disaster. For these restarted units, Safety Improvement Assessment is mandated to be conducted after every outage by the new regulatory requirements. The assessment shall be reported to Nuclear Regulatory Authority (NRA) and disclosed on the Web. Kyushu Electric Power Company submitted the assessment report first in Japan to NRA on July 6, 2017 for Sendai unit 1, on September 25, 2017 for Sendai unit 2 in compliance with this requirement. NRA decided to hold open hearings to discuss continuous improvement of the Assessments among its secretariats and utilities, including that for following restarted plants. As a result of the hearings, NRA identified 10 areas for improvement (AFIs) on the Assessment. All utilities shall address these AFIs. This paper describes the overview of these assessments, the major AFIs and the efforts to address them.
