- Summary:
- The effectiveness of a neutron well correlation counter (NWCC) and a random driver (RD) for plutonium-containing item assay and loss detection has been studied. The items were 4 in. x 2 in. x 1/4 in. stainless steel-clad metal plates and 6 in. x 3/8 in. stainless steel-clad oxide rods, each in two types of containment. It was found that absorption by dummies increases one's chance of detecting substitution over the chance of detecting simple removal. In all the loss-detection tests, however, there was only one failure to detect a loss. The NWCC did not separate out (..cap alpha..,n) neutrons well enough that one could use a calibration made with plates to assay for rods. The RD was found to have minimal usefulness for the assay of irradiated plates.
