Abstract

Un tel dispositif est destiné à recueillir, en cas d'incident, les débris du coeur détruit d'un réacteur nucléaire refroidi par liquide. Selon l'invention le dispositif collecteur 5, placé sous le coeur 4 dans la cuve de réacteur 6 remplie de réfrigérant 3, est recouvert, sur le côté tourné vers le coeur 4, d'au moins une couche d'un matériau à pores ouverts ou perforé. Cette couche peut notamment être formée de tissus métalliques. Elle a pour but de réduire la température à la surface du dispositif collecteur 5 en cas d'incident L'invention est applicable en particulier aux surrégénérateurs rapides refroidis au sodium.Such a device is intended to collect, in the event of an incident, the debris from the destroyed core of a liquid-cooled nuclear reactor. According to the invention, the collector device 5, placed under the core 4 in the reactor vessel 6 filled with refrigerant 3, is covered, on the side facing the core 4, with at least one layer of an open-pore material or perforated. This layer can in particular be formed of metallic fabrics. Its aim is to reduce the temperature at the surface of the collecting device 5 in the event of an incident. The invention is applicable in particular to rapid breeder reactors cooled with sodium.
