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.

Particle fuels such as sphere-pac and vipac have been considered as promising fuel systems for fast reactors because of their inherent potential in remote operation, cost reduction, and incineration of minor actinides or low-decontaminated plutonium. The FUJI test addresses the questions of fabrication of mixed-oxide (MOX) particle fuels with high Pu content (20%) and its irradiation behavior during the start-up phase. Four kinds of fuel, i.e., MOX sphere-pac, MOX vipac, MOX pellet, and Np-MOX sphere-pac, have been and will be simultaneously irradiated under identical conditions in the High Flux Reactor in Petten, Netherlands. First results show that the particle fuel undergoes a substantial structure change already at the very beginning of the irradiation when the maximum power is reached. The changes in microstructure, i.e., the formation of a central void and the densification of fuel, decrease the fuel central temperature. Thus, the fast and strong restructuring helps to prevent central fuel melting at high power levels.
