AmberLite IRN9652 H Ion Exchange Resin is a Nuclear-grade, Macroporous, 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 IRN9652 H has a high capacity to remove cationic contaminants, especially 137Cs in the primary loop and sodium traces in the secondary loop steam generator blowdown conditioned with organic amines such as morpholine. It can operate in short beds at high linear velocity due to the fast kinetics enabled by its macroporous pore structure. It can also be used in a layered bed below the macroporous anion resin.
