New waste form for Defense Facility reduces radiation levels significantly.
The Defense Waste Processing Facility (DWPF) in South Carolina will use borosilicate glass to store radioactive waste, as it resists water leaching and has a low melting point. Tests show the glass is stable and can contain radioactive materials for long periods. The canister holding the glass is made of stainless steel and can generate heat. The canister's size was chosen to fit transportation and storage needs.
