abstract

Hydrogen safety is one of the most important issues for severe accident analysis. Comparing with the lumped parameter code, 3-D CFD code GASFLOW has more advantages for analyzing hydrogen related phenomena [1]. However, due to the lacking of passive containment cooling system (PCS) model, GASFLOW is inapplicable for hydrogen analysis of PWR with PCS. This paper shows the development procedure of PCS model, including the model introduction and validation. The main functions of the PCS model are the calculation of falling water film thickness, heat transfer between wall and film, and film evaporation. Then, the hydrogen safety analysis by GASFLOW with PCS model is performed for CAP1400.
