Abstract

Réacteur nucléaire refroidi au métal liquide intégrant un système complètement passif d’évacuation de la puissance résiduelle (EPUR) à source froide modulaire. L’invention consiste essentiellement à réaliser un réacteur nucléaire intégrant un système qui garantit à la fois: - une évacuation de la puissance résiduelle de manière totalement passive dès l’instant initial de l’accident ; - une évacuation de la chaleur à travers la cuve primaire ; - une réduction du risque d’interaction chimique entre le sodium (ou NaK) et le matériau qui assure la fonction de la source froide finale ; - la présence d’une source froide finale assurant la même fonction que les échangeurs du type sodium/air ou NaK/air, utilisés selon l’état de l’art, mais de nature différente (réservoir avec MCP).
