A passive and active interrogation crate counter (PACC) for safeguards and waste assays has been developed and installed for evaluation at a plutonium processing plant. Passive assay uses the coincident neutron correlation technique. Active assay uses the differential die-away time technique. Assays are affected by the waste matrix. Under 100 nCi per gram of waste can be reliably detected by the passive methods. The measurements have demonstrated some differences between plant waste and prepared standard matrices. Detectability for active assay is well below 30 nCi/g in the 1.22 m by 1.22 m by 2.13 m crates. 3 references, 2 figures, 1 table.
