Description

Since the Fukushima Dai-ichi accident, the importance of 'system safety' has been recognized. Particularly, on the system safety assessment of plants in operation, the various degradation aspects with transition of time has been emphasized. Accordingly, functional degradation will be the assessment target, and the changes in the safety codes and the concept of safety will be dealt with; where, the reliability assessment will be made on the consolidation of important functions under a system, not on individual components. The basic function of the system will be evaluated for each systems and subsystems on all of the plant. Reliability assessment for which damage risk of the three key factors - Shut-down capability, Core cooling capability and Boundary conditions - will be evaluated by applying the Defence-in-Depth concept.
