Description
AmberLite™ IRN97 H Ion Exchange Resin is a Nuclear-grade, Uniform Particle Size, Gel, Strong Acid Cation Exchange Resin for Water Treatment Applications in the Nuclear Power Industry. It 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™ IRN97 H is a higher capacity, 10% 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 results in a lower pressure drop compared to conventional resins. The particle size of AmberLite™ IRN97 H is specifically designed to give an optimized balance of pressure drop, exchange kinetics, and resistance to separation from the anion exchange resin, AmberLite™ IRN78 OH Ion Exchange Resin, when used in a mixed bed.
Uses
- Primary water treatment: primary coolant purification, treatment of primary coolant blowdown, control of reactor coolant chemistry by removing excess 7Li, potassium or ammonium
- Fuel pool purification in single bed VVER systems in oxidative conditions
- Rad waste treatment and decontamination: removal of radioactive cations such as 137Cs and cobalt isotopes
- PWR steam generation blowdown (APG)
Advantages
- Nuclear-grade resin with minimum of ionic and non-ionic contamination
- Uniform particle size
- Highly regenerated ready for use
- High loading capacity
- Low residuals of all metallic species
- Optimized balance of pressure drop, exchange kinetics, and resistance to separation from the anion exchange resin, AmberLite™ IRN78 OH Ion Exchange Resin, when used in a mixed bed.
