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 use of a photon intermediate direct energy conversion (PIDEC) process to develop a proof of concept of a long-lived and efficient nuclear battery powered by a radioactive beta source is discussed. Fundamentally, PIDEC is a means of matching the scale length of the range of radiation to the scale length of the transducer. The device uses a photovoltaic cell and excimer gas-based photon source. In this work, argon was used to produce the excimer photon source (argon excimer at 129 nm) with a pressure range from 7 × 10-3 to 1.4 × 107 Pa (10-6 to 2100 psig). The beta source used in this study was a 90Sr source that has a daughter, 90Y, that then decays to stable 90Zr. Intermediate shielding from lead and an argon gas plenum were used to prevent damage to the photovoltaic cell. This battery demonstrated power variations with gas pressure as expected, and no radiation damage to the photovoltaic cell was observed over a period in excess of 150 h. Such a long exposure period demonstrates the desired tolerance of the device to the direct radiation damage that would otherwise be sustained in normal semiconductor-based energy conversion systems.
