Abstract: An organic waste containing halogen is destroyed by treatment in a molten salt pool comprising a mixture of a basic alkaline earth metal compound with an alkaline earth metal halide. An oxygen-containing gas is introduced into the pool containing the waste to produce a gaseous combustion product and to cause the halogen present in the waste to react with the basic alkaline earth metal compound to produce additional alkaline earth metal halide.

Abstract: A method of decladding an assembly comprising an element selected from the group consisting of uranium, thorium and mixtures thereof, clad in stainless steel, zirconium, or an alloy consisting essentially of zirconium and containing minor amounts of nickel, chromium, tin, iron or combinations thereof. In a first step the cladding is scored or perforated to expose the selected element. Thereafter, the assembly is exposed to a hydrogen atmosphere at an elevated temperature for a time sufficient for the hydrogen and selected element to react and form a hydride. The temperature then is further increased to decompose the hydride back to gaseous hydrogen and the selected element. The hydriding-dehydriding preferably are repeated at least two additional times to ensure complete release of any volatile gases present.
