Title (EN) RACKING DEVICE FOR STORING AND/OR TRANSPORTING NUCLEAR FUEL ASSEMBLIES, INCLUDING STAGES WITH DIFFERENTIATED FUNCTIONS
(FR) DISPOSITIF DE RANGEMENT POUR L'ENTREPOSAGE ET/OU LE TRANSPORT D'ASSEMBLAGES DE COMBUSTIBLE NUCLEAIRE, COMPRENANT DES ETAGES A FONCTIONS DIFFERENCIEES
Abstract:
(EN) The invention relates to a racking device for storing and/or transporting nuclear fuel assemblies, including first stages (Ei-1, Ei+1) for neutron absorption and thermal conductivity, as well as second stages (E2i) for mechanical strength arranged so as to alternate with the first stages, each first stage (Ei-1, Ei+1) including first and second assemblies having interlacing notches (6a, 6b) made of aluminium alloy including boron, and each second stage (Ei) comprising first and second structures (7a, 7b) stacked in the stacking direction (8) and each made of one or more materials which are free of neutron-absorbing elements, said structures (7a, 7b) being free of notches on the opposite edges thereof in the stacking direction (8).
(FR) L'invention concerne un dispositif de rangement pour l'entreposage et/ou le transport d'assemblages de combustible nucléaire, comprenant des premiers étages (Ei-1, Ei+1) d'absorption neutronique et de conductivité thermique, ainsi que des seconds étages (E2i) de résistance mécanique agencés en alternance avec les premiers étages, chaque premier étage (Ei-1, Ei+1) comprenant des premier et second ensembles à encoches entrecroisés (6a, 6b) en alliage d'aluminium comprenant du bore,et chaque second étage (Ei) comportant des première et seconde structures(7a, 7b) empilées selon la direction d'empilement (8) et chacune réalisée dans un ou plusieurs matériaux dépourvus d'éléments absorbeurs de neutrons, ces structures (7a, 7b) étant dépourvues d'encoches sur leurs chants opposés selon la direction d'empilement (8).
