Title (EN) SOLID INTERFACE JOINT WITH OPEN POROSITY, FOR NUCLEAR FUEL ROD
(FR) JOINT D'INTERFACE SOLIDE A POROSITE OUVERTE POUR CRAYON DE COMBUSTIBLE NUCLEAIRE
Abstract: front page image
(EN)The invention relates to a novel interface between the sheath (2) and the stack of pellets (5) in a nuclear fuel rod. According to the invention, an interface joint is inserted between the sheath and the column of fuel pellets over at least the height of said column. Said joint is made from a neutron-transparent material and takes the form of a highly heat-conductive structure (3) with open porosity, designed such that it can deform by compression along the thickness thereof. The invention also relates to associated production methods.
(FR)L'invention concerne une nouvelle interface entre la gaine (2) et l'empilement de pastilles (5) dans un crayon de combustible nucléaire. Selon l'invention, un joint d'interface en matériau transparent aux neutrons, sous la forme d'une structure (3) de conductivité thermique élevée et à porosité ouverte, adapté pour se déformer par compression selon son épaisseur, est inséré entre la gaine et la colonne de pastilles de combustible sur au moins la hauteur de cette dernière. L'invention concerne aussi des procédés de fabrication associés.
