This report contains the findings of a continuing program for the testing and evaluation of both Acid-Thorex and Purex flowsheets in HTGR fuel reprocessing. The tests were conducted to extend earlier studies on the effects of solvent degradation, feed solids impact, and decontamination performance using tracer 95Zr. Experiments to date indicate that acceptable operation is attainable in the reprocessing of HTGR fuels through the use of tributyl phosphate (TBP) extractant and pulsed solvent extraction columns. A centrifugal contactor is acceptable for the extraction step of the Purex flowsheet.

Acid-Thorex flowsheets using tributyl phosphate (TBP) to process feed which simulated that from HTGR fuels were tested in pulsed solvent extraction columns. Tests were performed to study the effects of solvent degradation and solids in the feed and decontamination performance using tracer Zr-95. Equipment recommendations for each process step are made. The Acid-Thorex process is expected to provide relatively trouble-free operation in commercial reprocessing of HTGR fuel. (auth).

The two-cycle Acid-Thorex solvent extraction process requires that the feed stream to each thorium cycle be processed to reduce its nitric acid concentration (feed adjustment). This interim development report presents the results of bench-scale and pilot-plant-scale feed adjustment experiments using a continuous mode of operation. An examination of formic acid denitration and fluoride ion volatilization is also included.
