概要
Particularly, Since the on Fukushima the system Dai-ichi safety assessment accident, the of importance plants in operation, of “system the safety” various has degradation been recognized. aspects with transiti on of time ha been emphasized. Accordingly, functional degradation will be the assessment target, reliability and assessment the changes will in the be made safety on codes the consolidation and the concept of of important safety will functions be dealt under with; a where, system, the not on individual components.
