Title
(EN) DEVICES, SYSTEMS, AND METHODS FOR REMOVING HEAT FROM A NUCLEAR REACTOR CORE
(FR) DISPOSITIFS, SYSTÈMES ET PROCÉDÉS D'ÉLIMINATION DE LA CHALEUR D'UN CŒUR DE RÉACTEUR NUCLÉAIRE
Abstract
(EN) A heat pipe configured to remove heat from a nuclear reactor core is disclosed herein. The heat pipe can include an Inner housing defining an inner volume configured to accommodate a heat source and an outer housing configured about the inner housing and the heat source. A wick can be positioned between at least a portion of the inner housing and at least a portion of the outer housing, wherein the wick can include a capillary material, and wherein the wick can define an intermediate volume between the inner housing and the outer housing. A working fluid can be positioned within the intermediate volume, wherein the working fluid can evaporate at a first end of the heat pipe and condense at a second end of the heat pipe adjacent to a heat exchanger, and wherein the wick can return condensed working fluid to the first end of the heat pipe.
(FR) Un caloduc conçu pour éliminer la chaleur d'un cœur de réacteur nucléaire est divulgué ici. Le caloduc peut comprendre un boîtier interne délimitant un volume interne conçu pour recevoir une source de chaleur et un boîtier externe conçu autour du boîtier interne et de la source de chaleur. Une mèche peut être positionnée entre au moins une partie du boîtier interne et au moins une partie du boîtier externe, la mèche pouvant comprendre un matériau capillaire, et la mèche pouvant délimiter un volume intermédiaire entre le boîtier interne et le boîtier externe. Un fluide de travail peut être positionné à l'intérieur du volume intermédiaire, le fluide de travail pouvant s'évaporer au niveau d'une première extrémité du caloduc et se condenser au niveau d'une seconde extrémité du caloduc adjacente à un échangeur de chaleur, et la mèche pouvant renvoyer le fluide de travail condensé à la première extrémité du caloduc.
