Settling Test Using Simulants to Evaluate Uranium Metal Distribution in K Basin Sludge

Abstract

This report presents the results of a large-scale settling test conducted with a K Basin sludge simulant that included metallic tungsten/cobalt (W/Co) fragments (density ~14.5 g/cm3) as a surrogate for uranium metal (density 19 g/cm3). The objective of the testing was to gain insight into how uranium metal is likely to be distributed within the K Basin sludge loaded into the large-diameter containers (LDCs) that will be used for storage at T Plant. In the LDCs, uranium metal will react with water and generate heat and hydrogen gas. During loading, transportation, and storage operations, the uranium metal distribution in the LDCs will have an impact on the thermal stability. Approximately 50 m3 of K Basin sludge have accumulated during the storage of more than 2100 metric tons of N Reactor fuel elements in two water-filled concrete pools {K East and K West Basins) in the 100K Area of the Hanford Site.
