Abstract
We describe a computer-based gamma ray spectrometer system using a germanium detector for rapid nondestructive measurement of isotopic and total plutonium concentrations in solutions at nuclear reprocessing plants. We have measured isotopic concentrations with an accuracy of +0.5Z. We discuss cell design, calibration techniques, and preliminary results. This system is being installed at the Tokai reprocessing plant in Japan.
