Title (EN) THERMAL MANAGEMENT OF MOLTEN FUEL NUCLEAR REACTORS
(FR) GESTION THERMIQUE DE RÉACTEURS NUCLÉAIRES À COMBUSTIBLE FONDU
Abstract:
(EN) This disclosure describes various configurations and components of a molten fuel fast or thermal nuclear reactor for managing the operating temperature in the reactor core. The disclosure includes various configurations of direct reactor auxiliary cooling system (DRACS) heat exchangers and primary heat exchangers as well as descriptions of improved flow paths for nuclear fuel, primary coolant and DRACS coolant through the reactor components.
(FR) L'invention concerne diverses configurations et composants d'un réacteur nucléaire thermique ou rapide à combustible fondu pour gérer la température de fonctionnement dans un cœur de réacteur. L'invention concerne diverses configurations de système de refroidissement auxiliaire de réacteur direct (DRACS) des échangeurs de chaleur et des échangeurs de chaleur primaires ainsi que des descriptions de voies d'acheminement améliorées pour le combustible nucléaire, un liquide de refroidissement primaire et un liquide de refroidissement DRACS à travers les composants de réacteur.
