| Abstract: | This paper presents the probabilistic safety analysis(PSA)of containment cooling system in passive special safety facility for Chinese advanced PWRs of nuclear power plants AC600.The unavailability of the system,contribution of main parts fault to the unavailability and the key importance of each component are calculated by fault tree analysis technology.Comparing the results of the several existed PWRs at home and abroad,it can be concluded that passive containment cooling system of AC600 has a considerable improvement in terms of safety,reliability and economics.As a new design,it has a lot of topics to study further. |
