Investigation into the reduction of antimony

This paper describes a program being implemented to decrease the antimony being released in waste water from the processing of liquid low-level radioactive wastes. The process being studied is the use of a crossflow membrane filter to remove antimony, and possibly cobalt 58. The process will evaluate the efficiency gains available from changing the oxidation states of the antimony with respect to the removal efficiency. Ion absorbers and ion exchange media will also be evaluated. The equipment is to be first tested on waste water from the November outage of Oconee, and then to use it on other radwaste processing studies
