Title (EN) ASSEMBLY FOR AN FNR-NA-TYPE NUCLEAR REACTOR, WITH A HOUSING PROVIDED WITH SPACER PLATES WITH IMPROVED RIGIDITY
(FR) ASSEMBLAGE POUR REACTEUR NUCLEAIRE DE TYPE RNR-NA, A BOITIER MUNI DE PLAQUETTES D'ESPACEMENT A RAIDEUR AMELIOREE
Abstract:
(EN) The invention relates to an assembly for a nuclear reactor, particularly for a sodium-cooled fast-neutron reactor RNR-Na, comprising a housing (10) with a longitudinal axis (X), each main face of the housing comprising, in the central part thereof, a spacer plate (2) with an adjacent assembly, comprising a part projecting towards the outside, the assembly also comprising a reinforcing sleeve (3) which is added inside the housing (10) and held therein, arranged next to the plates (2).
(FR) L'invention concerne un assemblage pour réacteur nucléaire, notamment pour un réacteur à neutrons rapides refroidi au sodium RNR-Na, comportant un boîtier (10) d'axe longitudinal (X), chaque face principale du boîtier comprenant, dans sa partie centrale, une plaquette (2) d'espacement avec un assemblage adjacent, comprenant une partie faisant saillie vers l'extérieur, l'assemblage comprenant en outre un manchon de renfort (3) rapporté et maintenu à l'intérieur du boîtier (10) et agencé en regard des plaquettes (2).
