Automated Gamma Isotopic Demonstration

Automated Gamma Isotopic Demonstration

Similar to sampling from the earliest nuclear power plant startups, today this task is primarily per-formed by entering the radiologically controlled area, collecting the coolant samples manually, taking them to an assay laboratory and analyzing in a calibration-qualified counting geometry with a high purity germanium (HPGe) gamma spectrometry system. Technology today allows for more advanced monitoring and data analysis and evaluation while monitoring remotely. These manual processes are time and resource intense, creates the risk for spills and exposes the staff to radia-tion fields during sampling and sample preparation. Furthermore, potentially useful information from short-lived radionuclides or dynamic isotopic activity changes between the discrete sampling periods may provide early indications of adverse conditions that could be lost with existing sam-pling frequencies. This paper reviews the recently completed high purity germanium automated sample collection and analysis project performed at Monticello Nuclear Power Station.
