The benefits of specialty macroporous resins in nuclear power plant operations

Nuclear power plant operations benefit significantly from the use of specialty macroporous ion exchange resins. Greater dose is being retained on cleanup beds during outage activity and lower activity is remaining in systems and being released to radwaste treatment. Information on the macroporous cation Purolite registered NRW160 loading and selectivity over gel resins with emphasis on cobalt, cesium, and other metals is reviewed. The performance of the macroporous anion NRW5010 as related to particulate removal such as iron, cobalt, and isotopes forming iron complexes is also discussed. Additionally, a new next-generation macroporous anion NRW5070 is introduced along with new applications. (orig.)
