In the vitrification process, radioactive waste is mixed with a substance that will crystallize when heated e. Once cooled, the now-solid vitrified waste within the canisters can be disposed of permanently and safely.
Once this test is completed, the low-activity waste glass containers will be stored in the Integrated Disposal Facility at the Hanford Site. Waste is mixed with glass-forming chemicals in a furnace to form molten glass that then solidifies in canisters, thereby immobilizing the waste.
Waste is mixed with silica and other glass-forming materials at the Low-Activity Waste Facility. Spent nuclear fuel is kept in pools of recirculated water to keep it cool while the increased radioactivity dies down before it either reprocessed to recover the plutonium or kept in dry storage for eventual deposit into a geological repository.
The resulting solid is then likely to be packaged, which provides additional barriers to contamination of the environment, but the effects of radiation on the surrounding matrix packaging are not negligible.
No spam, we promise. Additives used in cryobiology or produced naturally by organisms living in polar regions are called cryoprotectants.
