For five and one-half years, liquid wastes at Oak Ridge National Laboratory (ORNL) which contained low levels of beta and gamma activity have been decontaminated by a scavenging-precipitation, ion exchange process (SP-IX). Some of the activity is precipitated with caustic, and the remainder is sorbed on a cation resin, Duolite CS-100. Cesium-137 activity is routinely reduced to 30 Bq/L, and /sup 90/Sr to 0.5 Bq/L. Operation of the plant in 1977 cost $4.64 per thousand gallons (approx. 0.1 cent/L). The routine flow rate is 375 L/min.
