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.

CVD-tungsten coated Divertor Mock-UPS were fabricated and tested in an ion beam test facility in JAERI. The mock-up consisted of a 2 mm thick CVD-tungsten on a 30 wt% Cu infiltrated tungsten skeleton heat sink. For the thermal fatigue tests, the heat load of 15 MW/m2, 0.3 s was applied to simulate the bonding interface temperature under a steady heat load of 5 MW/m2. The mock-up successfully endured a heat load of 15 MW/m2, 0.3 s for more than 1000 thermal cycles. No cracks were observed at the bonding interface by optical microscope observation. Screening tests were also performed to evaluate the performance limit of the mock-up. The mock-up endured up to a heat load of 20 MW/m2, 10 s without failure.
