Abstract (en)

[origin: EP0055679A2] The casing for the underwater storage of fuel assemblies comprises a parallelepipedal metal envelope coated on the outside with a neutron absorbing material. The thickness of the metal envelope is comprised between 1.5 and 2.5 mm and the thickness of the coating is at the most equal to 2 mm The mass of boron carbide per cm<s2>s of surface of casing exceeds 0.146 g. The coating may be obtained by projection by a plasma torch of boron carbide grains completely coated with nickel or by gravity deposit of boron carbide fixed on the casing by electrolytic or chemical deposit of nickel. The invention applies to the storage of fuel assemblies in swimming pools.
