Abstract

Réacteur nucléaire refroidi par un métal liquide, comportant une cuve contenant le coeur du réacteur immergé sous le niveau du métal liquide, cette cuve étant suspendue sous une dalle de fermeture s'étendant au-dessus du niveau et étant séparée de celui-ci par une atmosphère d'un gaz inerte, ladite dalle étant traversée par des composants répartis autour du coeur. Selon l'invention, le réacteur comporte, montée sous la dalle dans l'atomosphère de gaz inerte au-dessus du niveau du métal liquide, une structure calorifuge souple, parallèle à la dalle mais séparée de celle-ci, cette structure s'étendant latéralement à partir de la paroi interne de la cuve et étant traversée par des viroles de passage des composants à travers la dalle. Application aux réacteurs à neutrons rapides.Nuclear reactor cooled by a liquid metal, comprising a vessel containing the core of the reactor submerged below the level of the liquid metal, this vessel being suspended under a closing slab extending above the level and being separated therefrom by a an inert gas atmosphere, said slab being traversed by components distributed around the core. According to the invention, the reactor comprises, mounted under the slab in the inert gas atomosphere above the level of the liquid metal, a flexible heat-insulating structure, parallel to the slab but separated from it, this structure extending laterally from the internal wall of the tank and being crossed by ferrules for passing the components through the slab. Application to fast neutron reactors.
