AmberLite IRN317 OH

Summary

Product identification

AmberLite™ IRN317 Li/OH Ion Exchange Resin is a mixture of nuclear-grade, uniform particle size, gel, strong acid cation and strong base anion exchange resins designed for water treatment applications in the nuclear power industry. It is composed of AmberLite™ IRN99 H Ion Exchange Resin (converted to the ⁷Li form at ≥99.9% isotopic purity) and AmberLite™ IRN78 OH Ion Exchange Resin, supplied together on a 1:1 equivalent basis. This product was previously sold as AmberLite™ IRN317 Ion Exchange Resin.

Applications

• Primary water treatment:
  • Primary coolant purification

Purity

AmberLite™ IRN Ion Exchange Resins are manufactured to nuclear-grade specifications with minimized inorganic impurities and special treatments to remove soluble organic compounds. This ensures systems remain free of contaminants and deposits, preventing increased radioactivity levels due to impurity activation. These resins are recommended for both non-regenerable and regenerable single or mixed bed applications requiring reliable production of high-quality water with minimal ionic and non-ionic contamination in the as-supplied form.
