Under the policy of "actively press ahead the construction of nuclear power",our nation imported the most advanced nuclear power technology,the 3rd generation of pressurized-water reactor nuclear power technology AP1000.But some security features of the AP1000 still haven’t be verified.As the last thermal trap of the power plant,the Passive Containment Cooling System(PCCS) is the very important part of the security system,and the study to PCCS is attracting more and more attention.The analysis of PCCS of AP1000 were studied on WGOTHIC program which was developed from GOTHIC program. GOTHIC (Generation of Thermal-Hydraulic Information for Containments)is a general purpose thermal-hydraulics computer program for design, licensing, safety and operating analysis of nuclear power plant containments and other confinement buildings. As the import of AP1000 nuclear technologies, the understanding and application of GOTHIC and WGOTHIC become important. In this essay the author built the model of Passive Containment Cooling System on the GOTHIC platform, and analyzed its reliability.The model solved the technical problems as listed below:(1)The movement of break flow in the containment.(2)The condensing of steam on the inside surface of steel containment.(3)The heat transport inside the steel containment.(4)The heat transfer between steel containment and water film on the outside surface of the containment.(5)The effect of sprinkler system.(6)The heat transfer between water film and air flow.
