DuPont™AmberLite™ IRN170 H/OHIonExchangeResinis designed specifically for use in nuclear loops where highest resin purity and stability are required, and where the "as supplied" resin must have a minimum of ionic and non-ionic contamination. These high standards of resin purity enable plants to achieve reliable and safe production whilst reducing the need for equipment maintenance and minimizing the impact of unscheduled outages. AmberLite™ IRN170 H/OHisdesignedfortheultimate performance in non regenerable nuclear applications, and it is the resin of choice for applications which demandthehighest effluent purity, highest operating capacity, and longest resin life. AmberLite™ IRN170 H/OHisastoichiometric equivalent mixture of AmberLite™ IRN99 HIonExchangeResinandAmberLite™ IRN78 OHIonExchange Resins on a1:1equivalent basis. Both the cation and anion components are recognized as the premier resins in the nuclear power industry. The cation component, AmberLite™ IRN99 H,hasexceptionally high capacity and outstanding physical and oxidative stability and the anion component, AmberLite™ IRN78 OH, has exceptional total exchange capacity and purity. AmberLite™ IRN170 H/OHwasoriginally developed for use in BWRcondensate polishers to help achieve the lowest possible sulfate levels in reactor water. This is accomplished through a combination of the extraordinary oxidative stability of the cation resin, and a particle size balance between the cation and anion resins, which minimizes the formation of a re-separated cation resin layer on the bottom of the service vessels. As a pre-mixed resin, it also allows for faster change-out and initial rinse-up prior to service, which minimizes start-up time and rinse wastewater volume Theexceptionally high total capacity of AmberLite™ IRN170 H/OH delivers an important benefit for many other nuclear applications including PWR steam generator blowdown treatment, PWRprimary system CVCSresinbeds, fuel pool demineralizers, and radioactive waste treatment. Since the nuclear-grade resins from all these applications are generally disposed of as rad waste, high capacity and long resin bed life are critical to minimizing rad waste disposal cost and volume. For most users, rad waste disposal cost will exceed resin purchase cost, so higher resin capacity directly translates into lower costs in these non-regenerable nuclear applications. Longer bed life also brings significant operational benefits such as fewer bed change-outs, less resin handling, and fewer chances for radiation exposure.

Purity

DuPont™AmberLite™ IRNIonExchangeResinsaremanufacturedasnuclear-grade using specific procedures throughout the manufacturing process to keep the inorganic impurities at the lowest possible level. Special treatment procedures are also utilized to remove traces of soluble organic compounds to meet the rigorous demands of the nuclear industry. These high standards of resin purity will help keep nuclear systems free of contaminants and deposits, and prevent increases in radioactivity levels due to activation of impurities in the reactor core. IRN resins are recommended in both non regenerable and regenerable single bed or mixed bed applications where reliable production of the highest quality water is required and where the "as supplied" resin must haveanabsolute minimumofionic and non-ionic contamination.
