Abstract
L'invention concerne un boitier pour le stockage sous eau d'assemblages combustibles. The invention relates to a case for storage under fuel assembly water.
Il comporte une enveloppe métallique parallélépipé dique revêtue extèrieurement d'une matière absorbant les neutrons. L'épaisseur de l'enveloppe métallique est comprise entre 1,5 et 2,5 mm et l'épaisseur du revêtement est au plus égale à 2 mm. La masse de carbure de bore par cm2 de surface du boitier est supérieure à 0.146 g. Le revêtement peut être obtenu par projection au chalumeau plasma de grains de carbure de bore entièrement enrobés dans du nickel ou par dépôt gravitaire de carbure de bore fixé sur le boitier par dépôt électrolytique ou chimique de nickel. It has a parallelepiped metal casing dique coated externally with a material absorbing neutrons. The thickness of the metal casing is between 1.5 and 2.5 mm and the thickness of the coating is at most equal to 2 mm. The mass of boron carbide by cm2 of surface of the case is greater than 0.146 g. The coating can be obtained by blowtorch projection fully coated boron carbide grain plasma in nickel or by gravity deposit of boron carbide fixed on the case by electrolytic or chemical deposition of nickel.
L'invention s'applique au stockage d'assemblages combustibles en piscine du combustible. The invention applies to the storage of assemblies fuel in fuel pool.
