摘要:
A chamber for reacting exothermic material, comprising a multilevel structure including at least: a receptacle for storing said material, corresponding to a lower level; a median level comprising a reactive load containing at least one alkaline-earth carbonate, so as to absorb heat emitted during the oxidation reaction of said material, said alkaline-earth carbonate decomposing under the effect of the heat in an endothermic reaction; an upper level comprising a cover. According to one variant, the material stored is a carbide of plutonium and/or uranium.
摘要:
A nuclear-fuel pin including a linear element made of a metal nuclear-fuel material consisting of uranium and/or plutonium, and cladding including Fe and Cr or an alloy including at least both of said elements, comprises a main shell provided around the linear nuclear-fuel element, said shell including threads or fibers made of SiC. A method for producing a nuclear-fuel pin is also provided.

A chamber for reacting exothermic material is disclosed, the chamber comprising a multilevel structure including at least: a receptacle for storing the material, corresponding to a lower level; a median level comprising a reactive load containing at least one alkaline-earth carbonate, so as to absorb heat emitted during the oxidation reaction of the material, the alkaline-earth carbonate decomposing under the effect of the heat in an endothermic reaction; an upper level comprising a cover. Optionally, the material stored is a carbide of plutonium and/or uranium.
摘要:
A method of manufacturing nuclear fuel elements comprising the steps of placing nuclear fuel balls in the container made from ultra-porous material, applying a CVI to the container and removing the container. The container for manufacturing fuel elements comprising balls, and is produced from at least one ultra-porous material, for example carbon foam.
