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 thermal performance of the first wall (FW) monoblock module, made from carbon fiber composite (CFC) or tungsten alloy with a castellated plasma phasing surface, was analyzed for runaway electron (RE) impact under reactor conditions. A water cooling system with Cu pipes embedded into the module is used. Calculations demonstrate that, in ITER, for an expected RE pulse duration [approximately]0.1sec and deposition energy of [approximately]30MJ/m2 , the heat generation in a W monoblock occurs within a thin surface layer ([approximately]10m) which, however, does not melt. In the CFC case, heat generation occurs deep in the bulk ([approximately]1000m), but CFC does not experience brittle destruction. The intense X-ray radiation caused by runaways is strongly attenuated within a 10-mm-thick layer of W and does not pose any threat for the cooling system. For the CFC case, a small but significant heat generation caused by the RE can occur in the Cu pipe.
