A crated waste assay monitor (CWAM) has been developed by Los Alamos National Laboratory to non-destructively assay sealed containers of selected waste from the Portsmouth Gas Centrifuge Enrichment Plant. The CWAM uses a nuclear analytical method (patented by Los Alamos) based on the neutron die-away principle and is designed to measure the amount of U-235 in spent alumina (from chemical traps) and in nonburnable solid wastes. Minimum accuracies will be of 10 and 20% respectively. A secondary function of the CWAM will be to measure U-238 in spent alumina with 25% minimum accuracy. These measurements are for domestic accountability and international accountability verification.
