摘要：The authors present operating principles of passive safety systems used in nuclear power plants using the example of the AP1000 plant.In particular,they describe the passive residual heat removal system and the passive containment cooling system.Moreover,the paper presents an analysis of a scenario involving the failure to start of active elements (Diesel generators) in the case of a loss of off-site power.The study presents the role of passive safety systems mentioned above in residual heat removal,as well as their impact on the temperature of the working medium in the cooling circuit and the refuelling water storage tank (IRWST).
