World may countries, which has an operating nuclear power plant already or plans to construct in order to meet growing power demand. Named PWR2000, which could be suitable to serve the future energy source of next generation nuclear power after APR1400. Therefore, the development of containment is one of key areas in advanced reactor development. In order to study for 2000MWe class containment, mainly two works have been done. The first, Mass and energy release data for PWR2000 was obtained through the analysis of a double ended guillotine break LOCA by using MARS 2.1 of system analysis code. The second, a methodology based on scaling principles is determined the PWR2000 containment size (height, radius, cooling system, etc.) according to the power level. The sensitivity analyses for important parameters of the containment size such as height, radius, volume and spray flow rate are also performed to see the effects on containment performance using CONTEMPT4/MOD4 code. For the passive containment adopted in PWR2000 obtains good economical benefits, which is possible that changing the vessel material and increasing the wall thickness of the vessel increased the containment vessel pressure. In conclusion, the net free volume of containment is one of the most important and sensitive parameter in containment analysis. And it was found that the containment pressure and temperature come to peak in accordance with the reduction of containment net volume.
