Abstract
A racking device is provided for storing and/or transporting nuclear fuel assemblies. The racking device includes 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) includes first and second assemblies having interlacing notches (6a, 6b) made of aluminium alloy including boron. Each second stage (Ei) includes first and second structures (7a, 7b) stacked in a stacking direction (8) and each is made of one or more materials which are free of neutron-absorbing elements. The first and second structures (7a, 7b) are free of notches on their opposite edges in the stacking direction (8).
