摘要

#CMT# #/CMT# The assembly has vessels (2) placed in a sink of a concrete case (1) that is inserted in ground, where vessels are cylindrical in shape. The vessels rest on a base of the sink and permits inert gas e.g. argon, to circulate around the vessel and to join an argon gas plenum (7). A pressurized back plate (8) is supported by a cylindrical ferrule (11) resting on a cold base and connected to a pump (28) in another vessel by a U-shaped channel. #CMT#USE : #/CMT# Vessel assembly for a breeder nuclear reactor cooled by circulation of sodium or other liquid metal. #CMT#ADVANTAGE : #/CMT# The assembly permits to offer high rigidity with respect to accidents, earthquakes or any aggressions, while avoiding long bent pipe that is utilized in existing assembly, thus permitting to offer reduced encumbrance and reduced construction mass, and hence permitting to offer a compact vessel assembly. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an elevation view of a vessel assembly. 1 : Concrete case 2 : Vessels 7 : Argon gas plenum 8 : Pressurized back plate 11 : Cylindrical ferrule 28 : Pump.
