Abstract:
The invention relates to a storage device for storing and/or transporting nuclear fuel assemblies, which includes recesses ( 2 ) defined by separating partitions ( 9 ) defining first and second recesses ( 2 ), the partition comprising: two first walls ( 22 ) defining the first and second recesses and made of an aluminium-alloy material which is free of neutron-absorbing elements, and defining therebetween a first inter-wall space ( 28 ); two second walls ( 30 ) arranged in the first space ( 28 ) and made of a material which comprises neutron-absorbing elements, the distance between the inner ( 36 ) and outer ( 34 ) surfaces of each second wall ( 30 ) defining a thickness (e 2 ), and a distance (E) being defined between the outer surface ( 34 ) of each second wall and a median partition plane ( 20 ), the values meeting the condition 0.1≤e 2 /E≤0.43.

Claim (Index 1):
A storage device ( 1 ) for temporarily storing and/or transporting PWR type nuclear fuel assemblies, said device being intended to be housed in the cavity of a package and including a plurality of adjacent housings ( 2 ) each intended to receive a nuclear fuel assembly, the housings ( 2 ) being delimited by separating partitions ( 9 ,  11 ) at least one of which delimits on either side of the same first and second housings ( 2 ),\n characterised in that said partition ( 9 ,  11 ) comprises:\n two first walls ( 22 ) each partly delimiting, respectively with its external surface ( 24 ), said first and second housings ( 2 ,  2 ), both first walls ( 22 ) being made of a first material of aluminium alloy free of neutron absorbing elements, both first walls delimiting a first inter-wall space ( 28 ) therebetween; \n two second walls ( 30 ) arranged in the first inter-wall space ( 28 ) and made of a second material comprising neutron absorbing elements and distinct from the first material, each second wall having an external surface ( 34 ) facing one of both first walls ( 22 ), as well as an internal surface ( 36 ) arranged such that both internal surfaces ( 36 ) of both second walls are facing each other and delimit a second inter-wall space ( 38 ) therebetween, the distance between the internal ( 36 ) and external ( 34 ) surfaces of each second wall ( 30 ) defining a thickness (e 2 ), whereas a distance (E) is defined between the external surface ( 34 ) of each second wall and a median partition plane ( 20 ) parallel to the first and second walls ( 22 ,  30 ), \n said device being also characterised in that the thickness (e 2 ) and the distance (E) meet the following condition:\n 0.1\u2264 e 2/ E\u2264 0.43.
