Abstract

See full text

An improved system for passively removing hydrogen inside containment in a nuclear reactor in the event of a loss of coolant accident by means of catalytic hydrogen recombination. A baffle wall located inside containment is used to establish within containment an air upflow path and an air downflow path in convective exchange. The air upflow is past the area of the coolant lines and is effective to entrain hydrogen from the break and the air downflow path is in the area adjacent the containment wall. The air upflow path downstream of the coolant lines is ducted so as to confine the entrained hydrogen to the ducted air upflow path and catalytic hydrogen recombiners are located in the ducted air upflow path for recombining said entrained hydrogen with oxygen in said ducted air upflow.
