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 (26) 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 (22) of the coolant lines and is effective to entrain hydrogen from the break, and the air downflow path is in the area (28) adjacent the containment wall (12). 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.

La présente invention concerne une amélioration du système passif éliminant recombinaison catalytique l'hydrogène de l'enceinte de confinement d'un réacteur nucléaire en cas perte accidentelle de fluide caloporteur. Un déflecteur (26) à l'intérieur de l'enceinte de confinement y entretient un flux d'air ascendant et un flux d'air descendant entre lesquels s'établit un échange par convection. Au niveau de la zone (22) des tubes de fluide caloporteur, le flux d'air ascendant entraîne l'hydrogène issu de la fissure, le flux d'air redescendant en passant au niveau de la zone (28) voisine de la paroi de confinement (12). En aval des tubes de fluide caloporteur, la circulation du flux d'air ascendant est canalisée de façon à confiner l'hydrogène entraîné vers la circulation d'air ascendant canalisé. Les modules de recombinaison catalytique d'hydrogène disposés dans la circulation d'air ascendant canalisé recombinent avec l'oxygène du flux d'air ascendant canalisé l'hydrogène déjà entraîné.
