The need for, and the adequacy of, the sodium carbonate washing technique in chemical purification of tributyl phosphate-hydrocarbon extractant prior to its re-use in radiochemical processing was examined, primarily in terms of Ru, Zr, and Nb activities. Operating experience from ORNL Purex and Thorex Pilot Plants is compared with Hanford operations and upper limits for activities are suggested. Recommendations are made for development studies with the ORNL Power Reactor Fuel Processing Pilot Plant. (W.D.M.
