초록

A method for fabricating a composite cladding comprised of a moderate-purity metal barrier of zirconium metallurgically bonded on the inside surface of a zirconium alloy tube which improves corrosion resistance. The improved corrosion resistance of the liner is accomplished by suitable heat treatment of the Zircaloy-zirconium composite cladding to allow diffusion of alloying elements, notably Fe and Ni, from the Zircaloy into the zirconium, in particular, to the inner surface of the zirconium liner. This diffusion anneal reduces the undesirable tendency ...

청구항

Barrier fuel cladding made by a process comprising the following steps: tube reduction of a tube shell consisting essentially of a zirconium liner metallurgically bonded to a zirconium alloy tube interior surface, said step of tube reduction being accomplished by a step of cold working followed by recrystallization annealing to produce a first intermediate tube; heat treatment of said first intermediate tube; one or more steps of tube reduction of said heat-treated first intermediate tube by cold working followed by recrystallization annealing or stress ...
