Abstract

A large amount of hydrogen is released under the LOCA in marine nuclear reactor, which seriously affects the safety of ships, so it is very important to investigate the hydrogen risk in nuclear reactor cabin. The three-dimensional computational fluid dynamics code GASFLOW is used to simulate the hydrogen behavior in the cuboid reactor cabin under LOCA and analyze the hydrogen risk in different areas. The results show that hydrogen explosion and flame acceleration are likely to occur under the LOCA without hydrogen mitigation measures. The pressure and temperature of the cabin are less than the design value, but once hydrogen explosion occurs, the pressure and temperature may destroy the devices and the integrity of the cabin.
