Metal Waste : - The metal waste form consists of metallic ingots that are used to stabilize the stainless steel cladding material, non-actinide fuel matrix materials, and noble metal fission products. Actinides that remain in the cladding hulls after dissolution in the electrorefiner, are also present in the metal waste form. Zirconium metal is added to produce a lower melting point alloy. Its presence also allows for the formation of a durable zirconium-iron intermetallic. The actinides in the metal waste are primarily in this phase and are therefore, retained well in the waste matrix.

Using the metal waste furnace, the cladding hulls are heated under vacuum to approximately 1100 deg C, where the salt vaporizes and transports to a condenser where it is collected as an ingot. After completing the distillation phase, the crucible temperature is increased to melt the cladding hulls and related fission products into a consolidated crucible. Cooled metal ingots are packaged in waste cans to be placed in interim storage, but ready for the repository.

Equally important, the program prevents discharge of industrial metals that can reduce the quality of wastewater and biosolids that King County reclaims for beneficial uses.

The remaining metals in soils and biosolids are environmentally stable -- meaning they're chemically bound so tightly that they do not leach or move through the soil. Long-term local research confirms that biosolids metals pose no threat to nearby wells or surface water.
