ABSTRACT
Probabilistic Safety Assessment (PSA) is an important method to evaluate the safety concerns of Nuclear Power Plants (NPPs) from probability perspective. The Reliability, Availability, Maintainability, Inspectability (RAMI) approach was promoted by International Thermonuclear Experimental Reactor (ITER) organization system reliability and availability, reduce technical risks acceptable level perspective for fusion devices. Both PSA RAMI adopt probabilistic failure issues nuclear systems. In this contribution, analysis purposes, methods, objects, quantitative indexes were firstly compared. Then, integrated assessment based on reactors proposed, case study in-vessel LOCA accident performed demonstrate effectiveness proposed method. application results indicate that not only can perform PSA, but also reactors. integrates characteristics RAMI, breaks barrier between preliminarily solves some problems reactors, enriches connotation
