DuPont™ AmberLite™ IRN77 H Ion Exchange Resin is 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™ IRN77 H is a high capacity, 8% DVB cation resin used to remove cations for purification and pH control in primary water treatment. It contains a minimum of 99% of its exchange sites in the hydrogen form. The uniform particle size and the absence of fine resin beads result in a lower pressure drop compared to conventional resins.

Applications of Ion Exchange Resin

  • Primary water treatment: treatment of primary coolant blowdown, control of reactor coolant chemistry by removing excess 7Li, potassium or ammonium
  • Rad waste treatment and decontamination: removal of radioactive cations such as 137Cs and cobalt isotopes
  • PWR steam generation blowdown (APG)

Advantages of Ion Exchange Resin

  • Nuclear-grade resin with minimum of ionic and non-ionic contamination
  • Uniform particle size
  • Highly regenerated ready for use
  • Low residuals of all metallic species
