Near-real-time verification approaches for the process area of reprocessing plants
Near-real-time accounting is being considered as a technique for improving accounting timeliness in reprocessing plants. A major criticism of near-real-time accounting is perceived disclosure of proprietary data for International Atomic Energy Agency verification, particularly in verifying the inventory of solvent extraction contractors. This study indicated that the contribution of uncertainties in estimating the inventory of pulsed columns or mixer settlers may be significant compared with uncertainties in measured throughput and measurable inventory for most reprocessing plants; thus, verification may not be a serious problem. Verification can become a problem for plants with low throughput and low inventory in process tanks if contractor inventory variations or uncertainties are greater than /approximately/25%. Each facility must be evaluated with respect to its specific inventory throughput characteristics. 49 refs., 4 figs., 4 tabs.
