Abstract
Material balance uncertainties and nondestructive assay measurement systems are presented for model spent-fuel reprocessing and mixed-oxide fuel fabrication plants which are believed to be representative of future LWR plutonium recycle fuel facilities. Material balance uncertainties are given for conventional inventories with accounting periods ranging from 1 month to 1 year and for potential future on-line computerized inventories performed at end of shift or daily. Nondestructive assay measurement systems for plutonium assay of feed, product, scrap and waste materials are described.
