Summary
Product identification
AmberLite™ IRN170 H/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
AmberLite™ IRN170 H/OH is specifically designed for nuclear loops requiring the highest purity and stability. It aims to minimize ionic and non-ionic contamination, contributing to reliable operation, reduced maintenance, and fewer unscheduled outages. This resin is intended for non-regenerable nuclear applications demanding superior effluent purity, operating capacity, and resin life.
It is a stoichiometric equivalent mixture of AmberLite™ IRN99 H (cation resin) and AmberLite™ IRN78 OH (anion resin) on a 1:1 equivalent basis. The cation component offers high capacity and stability, while the anion component provides exceptional total exchange capacity and purity.
Originally developed for BWR condensate polishers to achieve low sulfate levels, its particle size balance minimizes cation resin layer reformation. As a pre-mixed resin, it facilitates faster change-outs and rinse-up, reducing start-up time and wastewater. Its high total capacity benefits other nuclear applications like PWR steam generator blowdown, PWR primary system CVCS, fuel pool demineralizers, and radioactive waste treatment, where its capacity and long life help minimize rad waste disposal costs and volume.
Applications
- Primary water treatment:
- Treatment of primary coolant blowdown
- Pre-outage cleanup
- Fuel pool purification
- Rad waste treatment and decontamination:
- Removal of radioactive cations (e.g., ¹³⁷Cs and cobalt isotopes)
- Removal of anionic radioactive material
- Removal of silver
- PWR steam generation blowdown (APG)
- BWR condensate polishing
Purity
AmberLite™ IRN Ion Exchange Resins are manufactured to nuclear-grade standards with specific procedures to minimize inorganic impurities. Special treatments are used to remove soluble organic compounds, meeting the demands of the nuclear industry. This high purity helps prevent system contaminants, deposits, and radioactivity increases from impurity activation in the reactor core. These resins are recommended for non-regenerable and regenerable single or mixed bed applications where high-quality water and minimal "as supplied" contamination are critical.
