Simulation on Steam Supply System of Comprehensive Environmental Reliability Test for CAP1400 Passive Containment System

The steam supply system provides steam for CAP1400 passive containment cooling system comprehensive environmental reliability test to simulate the release of steam inside the containment during an accident condition. In this paper, RELAP5/MOD3.3 program was used to establish a steam system imitating model and to carry out the analysis in order to obtain the steam supply system operating parameter of critical equipment, which provides the basis for setting the reference and test control systems.
