Near-real-time verification approaches for the process area of reprocessing plants

Conference ·
OSTI ID:6366786
; ; ;

Adoption of near-real-time accountancy in large reprocessing plants will necessitate more timely verification. We discuss techniques and instruments that are suitable for on-site verification of input, output, waste streams, and in-process inventory estimation of tanks, solvent extraction contractors, and concentrators. Calculations show that estimates of solvent extraction contractor inventories may make an insignificant contribution to the total uncertainty of the material balance, relative to the contributions by transfer and process tank inventory measurements. 45 refs., 2 tabs.
