Nondestructive assays of 55-gallon drums containing uranium and transuranic waste using passive-active shufflers

Conference ·
OSTI ID:7296373
A passive-active neutron shuffler for 55-gal. drums of waste has been characterized using more than 1500 active and 500 passive assays on drums with 28 different matrices. Flux-monitor corrections have been improved, the assay accuracy with localized fissile materials in a drum has been characterized, and improvements have been suggested. Minimum detectable masses for {sub 235}U with active assays and {sup 240}Pu{sub eff} with passive assays are presented for the various amounts of moderators and absorbers studied.
