Portable monitor for the determination of reactor coolant surface radionuclide activities. [PWR; BWR]
The determination of primary surface deposited radionuclide activities has, in the past, been severely limited by physical structures and equipment size. In order to simplify the acquisition of this in-plant data, a portable gamma spectroscopy system has been assembled. This system consists of a planar high purity germanium (HpGe) detector mounted in a Multi-use Portable Spectrometer (MPS) cryostat purchased from Princeton Gamma-Tech and an ND-Six portable multichannel analyzer (MCA) purchased from Nuclear Data, Inc. Weighing less than 30 pounds, the entire system is completely battery powered and allows storage of accumulated spectra on mini-cassettes. Shielding and collimation is provided by a tungsten-based alloy obtained from Teledyne Power Alloys. The analytical methodology necessary for determining pipewall surface activities and manway insert activities has also been developed.
