Correlations have been prepared for U equilibria in RA and RC type columns and are presented. Correlation of RC equilibrium data was much simpler than that of RA equilibrium data since in the RC system HNO/sub 3/ and UNH are the only solutes presert in significant amounts, while the RA system also contains H/sub 3/PO/sub 4/, H/sub 2/SO/sub 4/, NaNO/sub 3/ and fe rrous sulfamate. The final equilibrium correlations for TBP-HW #4 Flowsheet conditions indicate that approximately 3.5 equivalent stages are required in both the RA Column extraction section and the RC Column to reduce U losses below 0.5% of the feed U in the waste stream from each column. The corresponding number of transfer units is approximately 7.0 for both columns. (auth)
