AMBERLITE IRN99

AMBERLITE IRN99

AMBERLITE IRN99 is a nuclear grade, gel type, strong acid cation exchange resin with a combination of very high capacity and oxidative stability that enables a completely new level of performance in nuclear power applications. It is sold in the fully regenerated Hydrogen form and intended for use in non-regenerable single bed or mixed bed nuclear systems which demand the ultimate in effluent purity, operating capacity, and resin life. The particle size of Amberlite IRN99 is specifically designed to give an optimized balance of pressure drop, exchange kinetics, and resistance to separation from the anion exchange resin, Amberlite IRN78, when used in a mixed bed. In BWR condensate polishing, Amberlite IRN99 can help to achieve the lowest possible reactor water sulfate levels. The exceptionally high DVB crosslinker level of Amberlite IRN99 gives it the best oxidative stability of any gel cation resin available, thus minimizing the release of sulfonic acid leachables. Also Amberlite IRN99 is made at a particle size which reduces the chance of creating a separated cation resin layer at the bottom on the mixed bed service vessel. The very high total capacity of Amberlite IRN99, typically 2.5 eq/L, delivers another important benefit, not only in BWR condensate polishing, but also in other nuclear applications such as PWR steam generator blowdown treatment, PWR primary system CVCS resin beds, and even radioactive waste demineralizers. The high total cation exchange capacity can produce a 15 to 30% increase in operating throughput. 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 often exceed resin purchase cost, so high resin capacity directly translates into savings in these non-regenerable nuclear applications. Furthermore, longer bed life means fewer bed change-outs, less work, less resin handling, and less chance for radiation exposure.
