Studies and research concerning BNFP. Pilot-scale pulsed columns, aqueous continuous dual process and holdup studies
Experimental studies included in this report were conducted for the purpose of obtaining data supporting safeguards programs related to determination of near real-time solutes inventory in pulsed columns. Holdup tests on pulsed columns resulted in an empirical equation suitable for evalution of the average dispersed phase holdup in a column. Mass-transfer tests on pilot-scale columns, simulating the HA and 1C column coprocessing flowsheet conditions, were performed operating both columns with the aqueous phase continuous. The aqueous continuous HS column is efficient, has a lower uranium inventory, and considerably shorter phase contact time than the organic continuous column. Concentration profile and uranium inventory data were determined during each run. The newly developed mass rate measurement technique has been tested and proven suitable for determination of the solute`s inventory in a pulsed column.
