概要
Corrective action program (CAP) is one of the key elements to suppress the risk in the nuclear power station.Japanese new regulatory inspection scheme which is similar to US reactor over sight process (ROP) started in 2020.4. This new inspection scheme has a potential to improve licensees’ CAP effectiveness using well-organized graded approach supported by probabilistic risk assessment.This paper first explains some core elements of graded approach prepared in ROP and second reviews one year operation of new Japanese regulatory inspection scheme from this graded approach point of view, thirdly introduces the long-term quantitative safety effect of the application of graded approach in CAP.
