METHODS OF FORMING TRIURANIUM DISILICIDE STRUCTURES, AND RELATED FUEL RODS FOR LIGHT WATER REACTORS
A method of forming a triuranium disilicide structure comprises forming a mixture comprising uranium particles and silicon particles. The mixture is pressed to form a compact comprising the uranium particles and the silicon particles. The compact is subjected to an arc melting process to form a prel...

| description | A method of forming a triuranium disilicide structure comprises forming a mixture comprising uranium particles and silicon particles. The mixture is pressed to form a compact comprising the uranium particles and the silicon particles. The compact is subjected to an arc melting process to form a preliminary triuranium disilicide structure. The preliminary triuranium disilicide structure is subjected to a comminution process to form a fine triuranium disilicide powder. The fine triuranium disilicide powder is pressed to form a green triuranium disilicide structure. The green triuranium disilicide structure is then sintered. Additional methods of forming a triuranium disilicide structure are also described, as are fuel rods for light water reactors.
La présente invention concerne un procédé de formation d'une structure de disiliciure de triuranium comportant la formation d'un mélange comprenant des particules d'uranium et des particules de silicium. Le mélange est pressé pour former une pastille comprenant les particules d'uranium et les particules de silicium. La pastille est soumise à un processus de fusion à arc pour former une structure de disiliciure de triuranium préliminaire. La structure de disiliciure de triuranium préliminaire est soumise à un processus de fragmentation pour former une poudre fine de disiliciure de triuranium. La poudre fine de disiliciure de triuranium est pressée sous la forme d'une structure de disiliciure de triuranium vert. La structure de disiliciure de triuranium vert est ensuite frittée. L'invention concerne également des procédés supplémentaires de formation d'une structure de disiliciure de triuranium, ainsi que des barres de combustible pour réacteurs à eau ordinaire. |
