DuPont AMBERLITE IRN 160 Nuclear Grade Ion Exchange Resin – Frequently Asked Questions (FAQ)

Q1: What distinguishes IRN 160 from standard-grade ion exchange resins?

A: IRN 160 is specifically manufactured and tested to meet stringent nuclear industry requirements, including ultra-low levels of leachable metals, enhanced radiation stability, and strict quality control for trace impurities—ensuring reliable performance in critical primary coolant purification and spent fuel pool water treatment applications.

Q2: Is IRN 160 suitable for use in pressurized water reactor (PWR) primary coolant systems?

A: Yes—IRN 160 is widely specified for PWR primary coolant polishing due to its high selectivity for corrosion product cations (e.g., cobalt, iron, nickel), low pressure drop characteristics in mixed-bed configurations, and proven compatibility with high-purity, high-temperature, low-conductivity water environments.

Q3: How does IRN 160 perform under prolonged gamma irradiation exposure?

A: As a nuclear-grade resin, IRN 160 is formulated with radiation-resistant functional groups and matrix crosslinking to maintain structural integrity and ion exchange capacity over extended service life in high-radiation zones—though actual performance depends on cumulative dose, temperature, and operational cycling conditions.

Q4: Can IRN 160 be regenerated in situ, and what are the typical regeneration protocols?

A: IRN 160 is designed for conventional acid–base regeneration in mixed-bed or separate-bed configurations. Regeneration typically employs high-purity hydrochloric acid and sodium hydroxide solutions, with careful attention to rinse efficiency and conductivity endpoints to ensure minimal residual regenerant and optimal deionization performance.
