Title (EN) SODIUM-CESIUM VAPOR TRAP SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE PIÈGE À VAPEUR DE SODIUM-CÉSIUM
Abstract:
(EN) Sodium-cesium trap systems and methods for the simultaneous removal of both sodium (Na) and cesium (Cs) in gas are provided. The trap system includes a contacting vessel having an inlet and an outlet with carrier gas channeled therethrough. A heating system maintains a temperature gradient across the contacting vessel between a first temperature at the inlet and a second temperature at the outlet such that sodium and cesium contained within the carrier gas are condensed into liquid and the carrier gas exiting the vessel is substantially free of sodium and cesium.
(FR) L'invention concerne des systèmes et des procédés de piégeage de sodium-césium pour l'élimination simultanée à la fois du sodium (Na) et du césium (Cs) présents dans un gaz. Le système de piégeage comprend un récipient de contact comportant une entrée et une sortie, un gaz porteur étant canalisé entre celles-ci. Un système de chauffage maintient un gradient de température à travers le récipient de mise en contact entre une première température au niveau de l'entrée et une seconde température au niveau de la sortie, de sorte que le sodium et le césium contenus dans le gaz porteur soient condensés en liquide et que le gaz porteur sortant du récipient soit sensiblement exempt de sodium et de césium.
