Optimization of radwaste ion-exchange processes at nuclear power plants

Considerable emphasis is being given by nuclear utilities to optimizing the performance of radwast ion-exchange processes. Extension of ion-exchange capacity and increased efficiency for removal of chemical and radiochemical species means reduced costs for resin purchase and disposal. Mixed radwaste liquid presents a challenge for ion-exchange processes due to the presence of species that are deleterious to ion-exchange resin. This paper presents current results of the project sponsored by the Electric Power Research Institute to improve BWR and PWR radwaste ion-exchange performance
