Qualification of SRS's KAMS NMC and GIS Systems

[摘要] The Savannah River Site's KAMS facility was designed for the receipt and storage of incoming SNM shipments. MC and A requires confirmation and verification on these items. These items normally arrive packaged in a 9975. The KAMS facility has a Neutron Multiplicity Counter (NMC) and a Gamma Isotopic System (GIS) to support these measurements. This report will discuss the qualification of the NMC and GIS for KAMS receipts. The task was made significantly more difficult as the items contain a whole host of materials from Pu metal to mixed Pu/EU and from items relativity free from impurities to items containing significant amounts of impurities as they affect NMC assay. The 9975 container itself has proved to be a challenge for NDA work as it contains at least a 1/2 inches of heavy metal shielding as well as hydrogenous materials.
