Hydrogen Removal Analysis in Severe Accident Induced by Loss of Feed Water for XUDAPU Nuclear Power Plant
-
Abstract
After loss of feed water accident, if the safety features fail to start up, the primary will loss heat sink, which may lead core uncover to generate hydrogen by Zirconium-Water Reaction. The hydrogen release to the containment could cause deflagration or detonation, which would produce both high thermal and pressure loads on the containment. This paper use MAAP4 to analyze the hydrogen removal capability after the severe accident induced by loss of feed water.
