Application and management of ion exchangers in nuclear Industry.

What is it about?

The life cycle of the ion exchange materials was traced starting from material preparation to disposal. Within this context, sources of radioactive wastes and their important characteristics will be introduced. Exchanger preparation and characterization methods were overviewed. Chemical, mechanical, and radiological design criteria that affect performances of the process were summarized. Treatment and immobilization options of spent ion exchangers overviewed and methods to assess immobilization sustainability were highlighted.

Why is it important?

Ion exchange technique is one of the widely applied conventional treatment options in nuclear industry, which is used to reduce the volume of aqueous radioactive waste streams, to separate isotopes and in decontamination operations. After being exhausted, spent exchangers are considered as radioactive waste and consequently they must be safely managed to minimize their environmental impacts.
