摘要

A crated waste assay monitor (CWAM) has been developed by Los Alamos National Laboratory to nondestructively 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. 7 refs., 1 fig., 1 tab. (ERA citation 10:041418)
