College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

The structure and properties of CaF2-type δ structure of helium-containing zirconium hydrides were investigated using density functional theory. The properties of this material vary with hydrogen and helium concentrations. Hydrogen has a significant effect on the behavior of helium. The occupied sites of He atoms strongly depend on the hydrogen concentration. The structures and formation mechanisms of helium clusters vary with hydrogen concentration at a high helium content. The embedding energies of He atoms mainly result from interactions between helium and zirconium atoms. However, H-He interactions significantly contribute to the embedding energies. Variations in lattice volume expansion and bulk modulus were also investigated.
