Potential Benefits and Impacts on the CRWMS Transportation System of Filling Spent Fuel Shipping Casks with Depleted Uranium Silicate Glass: Civilian Radioactive Waste Management System
- Oak Ridge National Laboratory (ORNL), Oak Ridge, TN (United States)
A new technology, the Depleted Uranium Silicate Container Fill System (DUSCOFS), is proposed to improve the performance and reduce the uncertainties of geological disposal of spent nuclear fuel (SNF), thus reducing both radionuclide release rates from the waste package and the potential for repository nuclear criticality events. DUSCOFS may also provide benefits for SNF storage and transport if it is loaded into the container early in the waste management cycle. Assessments have been made of the benefits to be derived by placing depleted uranium silicate (DUS) glass into SNF containers for enhancing repository performance assessment and controlling criticality over geologic times in the repository. Also, the performance, benefits, and impacts which can be derived if the SNF is loaded into a multi-purpose canister with DUS glass at a reactor site have been assessed. The DUSCOFS concept and the benefits to the waste management cycle of implementing DUSCOFS early in the cycle are discussed in this paper.
