Nondestructive Assay Instrumentation for a Savannah River Plant Upgrade Project

We have designed and are developing three different computer-based spectrometer systems. Two will measure the concentration of Pu solutions by gamma-ray and by stimulated x-ray fluorescence emissions. The third will measure relative isotopic abundances from the gamma-ray emissions of solid samples in closed containers. All systems are coupled to remote terminals and bar code readers, and also to mini-computer based MCAs, which in-turn are linked to another computer to provide a state-of-the-art NDA measurement capability. Installation at SRP is planned in late 1985.
