Savannah River National Laboratory (report SRNL-STI-2017-00676) used the PHDS GeGI to perform gamma-ray imaging and holdup assays of Cells 1 and 2 in the 235-F Plutonium Fuel Form Facility. The measurements located and quantified Pu-238 holdup across cell features such as floors, walls, HEPA filters, furnaces, and gloveboxes, with uncertainties reported at one sigma. The imaging data refined the facility's holdup inventory to support deactivation and decommissioning of the Savannah River Site facility.
