Title
(DE) KERNREAKTOR MIT PRIMÄRSICHERHEITSWÄRMETAUSCHER
(EN) NUCLEAR REACTOR INCORPORATING A PRIMARY SAFETY HEAT EXCHANGER
(FR) REACTEUR NUCLEAIRE INTEGRANT UN ECHANGEUR DE CHALEUR PRIMAIRE DE SECURITE
Abstract
(EN) The invention relates to a nuclear reactor (10) comprising a vessel (100) incorporating at least one primary power heat exchanger (200) for cooling the primary liquid of the nuclear reactor during the normal operation of the reactor and at least one primary passive safety heat exchanger (120) for cooling the primary liquid of the nuclear reactor in the event of a malfunction in the normal cooling of the primary liquid of the reactor. The nuclear reactor (10) is characterised in that the vessel (100) comprises a compartment (110) arranged in the thickness thereof, and in that the primary passive safety heat exchanger (120) is at least partially contained inside said compartment (110).
(FR) L'invention se rapporte à un réacteur nucléaire (10) comportant une cuve (100) intégrant au moins un échangeur de chaleur primaire de puissance (200) pour le refroidissement du liquide primaire du réacteur nucléaire en fonctionnement normal du réacteur et au moins un échangeur de chaleur primaire de sécurité passif (120) pour le refroidissement du liquide primaire du réacteur nucléaire en cas de dysfonctionnement du refroidissement normal du liquide primaire du réacteur, ledit réacteur nucléaire (10) étant caractérisé en ce que la cuve (100) comporte un logement (110) ménagé dans son épaisseur et en ce que ledit échangeur de chaleur primaire de sécurité passif (120) est intégré au moins partiellement dans ledit logement (110).
