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.

Flow behavior of a jet issuing from a steam inlet nozzle of a Terry turbine, which is employed in the RCIC system of BWRs, was observed using PIV techniques. The nozzle has a complicated shape and sufficient data do not exist to predict flow phenomena including exhaust jet flow behavior. Single-phase air jet flow was applied for this experiment. The jet flows 10 mm from the nozzle then impinges on a flat wall which simulates the wall segment between buckets on a turbine wheel. The nozzle outlet pressure was set as 30 psi and 40 psi. Flow behavior and collision behavior was different between the two cases, which implies nozzle outlet pressure of Terry turbine also affects the flow behavior in the turbine. The flow behavior is very important to know how Terry turbine works in BDBE condition or to estimate actual life time of the RCIC system itself. This is the first trial to clarify the behavior and further work will be done in the future.
