Creators

Description

A nuclear fuel element is described. It includes a central core of nuclear fuel and composite cladding composed of a substrate (Zr alloy), provided with a protective coating on its internal face, in a material selected from oxidation resistant alloys containing chromium, a chrome coating alloyed to the substrate, a coating containing aluminium alloyed to the substrate or a coating containing silicon alloyed to the substrate. The oxidation resistant alloy is a high chromium stainless steel

Abstract (French)

On presente un element de combustible nucleaire. Il comprend un noyau central de combustible nucleaire et une gaine composite allongee, compose d'un substrat en alliage de zirconium pourvu d'une couche protectrice sur sa surface interieure, en un materiau choisi parmi les alliages resistant a l'oxydation renfermant du chrome, un revetement chrome allie au substrat, un revetement aluminie allie au substrat ou un revetement silicie allie au substrat. L'alliage resistant a l'oxydation est un acier inoxydable a haute teneur en chrome
