In this paper, the setup, calibration, and testing of the F-Area Analytical Labs active well neutron coincidence counter (HV-221000-NDA-X-1-DK-AWCC-1)
in SRNL are described for use in the Savannah River Site (SRS) transuranium metal production facility to enable assay of mixed
uranium/plutonium metal product. The instrument was required within a three-month window for availability upon receipt of
LANL uranium oxide samples into the SRS facility. Calibration of the instrument in the SRNL nuclear nondestructive assay facility
in the range 10–400 g HEU is described. We also report qualification and installation of the instrument for assay of the initial
suite of product samples.
