| Abstract: | Risk informed categorization of structures,systems and components(SSCs) for nuclear power plants is an integrated method by three steps,i.e.probabilistic risk assessment,deterministic estimation of defense-in-depth and sensitivity analysis.In the article,the deterministic estimating process is studied,and a set of revised process for risk informed categorization of SSCs is established.For selecting systems of auxiliary feedwater system,the containment spray system and component cooled water system from Daya... |
