Metal alloy treatment process for radioactive waste

摘要

A waste treatment process includes containing a reactant metal alloy (210) in a reactant alloy container (202) substantially isolated from oxygen gas. The reactant metal alloy includes at least one chemically active alkaline metal and at least one radiation absorbing metal. After heating the reactant alloy (210) in the reactant alloy container (202) to a desired operating temperature, a waste material including radioactive isotopes to be alloyed is introduced into the molten alloy, preferably below the surface of the alloy. Non-radioactive compounds in the waste material react with metals in the reactant alloy (210) to produce useful halogen salts and other materials. The metal radioactive isotopes in the waste material are alloyed with the alkaline metal and radiation absorbing metals to create a storage product for long term storage.
