LOW-RADIOACTIVTY-LEVEL WASTE TREATMENT. PART II. PILOT PLANT DEMONSTRATION OF THE REMOVAL OF ACTIVITY FROM LOW-LEVELnPROCESS WASTES BY A SCAVENGING-PRECIPITATION ION-EXCHANGE PROCESS

摘要

The presence of hexametaphosphate in the waste feed had a deleterious effect on the process, resulting in premature fission product breakthrough from the ion-exchange column. Consequently it is recommended that phos¬phate be excluded from the wastes. Should this approach be undesirable or impractical, sodium carbonate can be used as a process additive to increase resin bed capacity.
