DuPont™ AmberLite™ IRN77 H Ion Exchange Resin
Nuclear-grade, Uniform Particle Size, Gel, Strong Acid Cation Exchange Resin for Water Treatment Applications in the Nuclear Power Industry
Description
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
– 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
– Rad waste treatment and decontamination:
* Removal of radioactive cations such as 137Cs and cobalt isotopes
– PWR steam generation blowdown (APG)
AmberLite™ IRN77 H Ion Exchange Resin has previously been sold as AmberLite™ IRN77Ion Exchange Resin.
