LOW-RADIOACTIVITY-LEVEL WASTE TREATMENT. PARTI. LABORATORY DEVELOPMENT OF A SCAVENGING-PRECIPITATION ION-EXCHANGE PROCESS FOR DECONTAMINATION OF PROCESS WATER WASTES

摘要

A scavenging-precipitation ion-exchange process using phenolic (organic) resins was developed to decontaminate low-radioactivity-level process water waste prior to discharge to the environment. In laboratory and small engineering-scale tests, greater than 99° 9$ of the cesium and strontium the principal biological hazards, were removed from OREL low-level waste, and the total activity level was lowered to less than the maximum permissible concentration (for ex¬ample, Sr90 is 10-7 nc/ml) recommended for populations in the neighborhood of atomic energy installations。
