Laboratory results are presented for a flowsheet study of a process for decontaminating ORNL low level waste water. The water is adjusted to approximately pH 12 with NaOH, clarified, and passed through a bed of phenolic cation exchange resin. This study, using a phenoliccarboxylic resin, showed essentially the same results as those previously reported using a phenolic- sulfonic resin, i.e., radioactivities in ORNL waste were reduced to the order of 10% of MPC. The phenolic-carboxylic resin has the advantage that it can be regenerated with 0.5 M HNO3 instead of the 5 M HCl required for the phenolic-sulfonic resin. Volume reduction factors of 2000 to 3000 were achieved.
