Description
Mixture of Nuclear-grade, Macroporous Strong Acid Cation and Gel Strong Base Anion Exchange Resins for Water Treatment Applications in the Nuclear Power Industry
AmberLite IRN9687 Li/OH 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 IRN9687 Li/OH is composed of macroporous AmberLite IRN9652 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.
AmberLite IRN9687 Li/OH is characterized by a strong affinity for 137Cs and designed to be used for boron and lithium purification in PWR nuclear power operation.
Pre-mixed resin also allows for faster change-out and initial rinse-up prior to service, which minimizes start-up time and rinse wastewater volume.
