Radiation Waste Cleanup

Our CriticalResins™ removal of isotopes and ionic impurities from waters planned for reuse of discharge is properly addressed with the specialty mixed bed NRW3560 or the slightly more economical mixed bed NRW3240.

Radioactivity originating from the plant is treated with mixed bed ion exchange resins to reduce activity to an appropriate level for release back to the reactor. The mixed bed resin that is most appropriate for this application is NRW3240. Makeup goes to the hot well and is further polished by the condensate polishing system before entering the boiler.

Use of the layered specialty macroporous anion NRW5010 or NRW5070 and the macroporous cation NRW160 during outage cleanup generally improves treatability of wastewater collected during outage.

In the event there are difficult isotopes in the radwaste stream, there are many selective resins available for specific situations.
