The effects of operating faults or failures in a nuclear power plant involving discharge of steam from the circuit are limited by condensing the steam-air mixt. at supersonic speed by contact with liq. flowing in the same direction. The supersonic speed is itself generated by the energy released in the fault. The rate of condensation of the escaping steam is considerably increased. The size of the plant required is reduced and its reliability is regard to radioactive pollution of the environment is considerably improved. POUR LIMITER LES CONSEQUENCES DE LA FUITE DU CALOPORTEUR (EAU SOUS PRESSION PAR EXEMPLE) EN CAS DE RUPTURE DU CIRCUIT PRIMAIRE 7, ON FAIT CONDENSER LA VAPEUR D'EAU DU MELANGE VAPEUR-AIR FORME A LA SUITE DE L'INCIDENT DANS UN COURANT DE LIQUIDE A VITESSE SUPERSONIQUE RELATIVE. LE SYSTEME, ASSOCIE A UNE CENTRALE AYANT UNE ENVELOPPE ETANCHE 1 DANS LAQUELLE EST PLACE LE BLOC PILE 2, COMPORTE UN DISPOSITIF DE CONDENSATION FORCEE 5 DE LA VAPEUR. CE DISPOSITIF 5 COMPORTE AU MOINS UN INJECTEUR 12 DONT LA BUSE SUPERSONIQUE 16 EST RELIEE AU VOLUME 20 DE L'ENVELOPPE 1. LA CHAMBRE DE MELANGE 17 DE L'INJECTEUR 12 EST RELIEE AVEC UN RESERVOIR 13 CONTENANT UN LIQUIDE DE REFROIDISSEMENT 14. LE VOLUME GAZEUX 19 DU RESERVOIR 13 EST RELIE AU VOLUME 20. LE DIFFUSEUR 18 DE L'INJECTEUR 12 EST RELIE, A TRAVERS UN ELEMENT DE FERMETURE, A UN RESERVOIR DE COLLECTE DE CONDENSAT 15.
