Abstract:
1. Storage device for the storing and/or transporting of nuclear fuel assemblies, said device comprising a plurality of adjacent housings, each having a lateral wall, and being able to receive a nuclear fuel assembly therein, said lateral wall being realized using stacking and intercrossing slotted structural assemblies, the structural assemblies oriented lengthwise along a horizontal axis, each structural assembly including at least one plate realized in a first material comprising aluminium, characterized in that each structural assembly further comprises a tubular cross-section element having a hollow interior defined between an upper edge and a lower edge and two lateral flanks, wherein the at least one plate is slidably positioned within the hollow interior along the horizontal axis, the structural assembly having a plurality of vertical slots on its outer surface to allow stacking and intercrossing with an adjacent structural assembly to at least partially form said lateral wall, the at least one plate having a first vertically oriented notch and the tubular cross-section having a second vertically oriented notch, wherein the first notch and the second notch are located to coincide with one another to form the corresponding vertical slot when the at least one plate is positioned within the tubular cross-section element, the tubular cross-section element being realized in a second material selected from steels and titanium or alloys of steels and titanium.
