HECTR analysis of equipment temperature response to hydrogen burns in a subatmospheric containment building

Conference ·
OSTI ID:5664330
Analyses of equipment temperature response to hydrogen burns in a subatmospheric containment have been performed using the HECTR computer code. Parameters studied included LOCA break size and location, equipment location, containment spray operation and ignition criteria. HECTR predicts that the operation of igniters can lead to prolonged equipment temperatures in hydrogen source compartment that are higher than temperatures to which safety-related equipment is usally qualified. Further, if ignition is delayed and the containment sprays are operational, HECTR indicates potentially detonable mixtures can result.
