Receipts Measurements at SRS's KAMS Facility

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 container. An Ortec digiDART(tm) coupled to a nominally 2x2 NaI detector is generally used for confirmation measurements. The KAMS facility has a custom designed Neutron Multiplicity Counter (NMC) and a Gamma Isotopic System (GIS) to support verification measurements. 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 relate to NMC assay. The 9975 container itself has proved to be a challenge for NDA work as it contains at least 0.5 inches of heavy metal shielding as well as hydrogenous materials. Measurement issues will be addressed in this paper as they apply to the unique application posed by the KAMS environment. These include the 9975 shipping container, confirmatory Measurement Control Program (MCP), Shipper-Receiver reconciliations, and confirmatory receipts measurements vs. timeliness
