AmberLite IRN9766 OH

Summary

Product Identification

• Product Name: AmberLite™ IRN9766 OH Ion Exchange Resin
• Product Type: Nuclear-grade, Macroporous, Strong Base Anion Exchange Resin
• Intended Use: Water Treatment Applications in the Nuclear Power Industry
• Previous Name: AmberLite™ IRN9766 Ion Exchange Resin

Description

AmberLite™ IRN9766 OH Ion Exchange Resin is designed for nuclear loops requiring high resin purity and stability with minimal ionic and non-ionic contamination as supplied. It is effective in removing radioactive colloidal material, particularly 110mAg. Its macroporous structure allows for fast kinetics, enabling operation in short beds at high linear velocities, making it suitable as an overlay for mixed beds or cation resins.

Applications

• Primary Water Treatment:
  • Primary coolant purification
  • Treatment of primary coolant blowdown
  • Pre-outage clean-up
• Fuel Pool:
  • Purification in single bed VVER systems
  • Overlay for mixed bed systems or cation bed
• Rad Waste Treatment and Decontamination:
  • Removal of radioactive colloids
  • Removal of silver

Purity Standards

AmberLite™ IRN Ion Exchange Resins are manufactured to nuclear-grade specifications using specific procedures to minimize inorganic impurities and remove soluble organic compounds. This ensures nuclear systems remain free of contaminants and deposits, preventing increased radioactivity due to impurity activation. They are recommended for non-regenerable and regenerable single bed or mixed bed applications demanding reliable production of high-quality water with minimal contamination.
