Abstract

A new technology, the Depleted Uranium Silicate Container Backfill System (DUSCOBS), is proposed to improve the performance and reduce the uncertainties of geological disposal of spent nuclear fuel (SNF). DUSCOBS is designed to: (1) reduce radionuclide release rates from the waste package and (2) reduce the potential for repository nuclear criticality events. As a secondary benefit, it disposes of excess depleted uranium (DU). DUSCOBS also provides benefits for SNF storage and transport. These are discussed in a companion paper.
