AmberLite IRN164 OH

Summary

Product identification

AmberLite™ IRN164 Li/OH Ion Exchange Resin is a mixture of nuclear-grade, uniform particle size, gel, strong acid cation and strong base anion exchange resins. It is designed for water treatment applications in the nuclear power industry.

Description

This resin is specifically designed for use in nuclear loops requiring high resin purity and stability, with minimal ionic and non-ionic contamination. AmberLite™ IRN164 Li/OH is composed of AmberLite™ IRN97 H Ion Exchange Resin (converted to the natural Li form) and AmberLite™ IRN78 OH Ion Exchange Resin, supplied together on a 1:1 equivalent basis. It is intended for use in non-regenerable systems that demand high effluent purity and long resin life, such as CANDU reactor heat transport systems and closed-loop cooling systems. The resin properties are designed to reduce separation in mixed beds and improve slurrying capability, allowing for faster change-out and initial rinse-up.

Applications

• Primary water treatment:
  • Primary coolant purification

Purity

AmberLite™ IRN Ion Exchange Resins are manufactured to nuclear-grade standards, minimizing inorganic impurities and removing soluble organic compounds to meet the rigorous demands of the nuclear industry. This helps maintain nuclear systems free of contaminants and deposits, and prevents increased radioactivity levels due to impurity activation.
