METHOD FOR CLEANING RADIOACTIVE PROCESS WATER FROM CESIUM RADIONUCLIDES IN NUCLEAR ENGINEERING Russian patent published in 1998 - IPC

FIELD: decontamination of process water by using sorption method. SUBSTANCE: method involves passage of water current through column filled with ferrocyanide-containing sorbent at temperature of 30 to 90 C. Linear velocity of current is at least 1•10^-4 m/s. According to our method, use may be made of two sorbent-holding columns one being used in the course of process and other column is loaded with fresh sorbent. Process water may be pre-cleaned of suspended and solid particles, and oil products. EFFECT: facilitated procedure. 3 cl, 1 dwg , 6 ex
