Depleted Uranium (DU) Dioxide Fill

DU dioxide in the form of sand may be used to fill the void spaces in the waste package after the package is loaded with SNF. This application could use half or more of the DU inventory and may provide several benefits: long-term repository criticality control, radiation shielding, improved repository performance, and support of the exterior waste package wall against external forces.
