AmberLite IRN97 H

Summary

Product Identification

• Product Name: AmberLite™ IRN97 H Ion Exchange Resin
• Grade: Nuclear-grade, Uniform Particle Size, Gel, Strong Acid Cation Exchange Resin
• Manufacturer: DuPont

Description

AmberLite™ IRN97 H is a strong acid cation exchange resin designed for water treatment applications in the nuclear power industry. It is a 10% DVB cation resin with a minimum of 99% of its exchange sites in the hydrogen form (H⁺). The uniform particle size and absence of fine beads contribute to lower pressure drop. It is designed for use in mixed beds with AmberLite™ IRN78 OH Ion Exchange Resin.

Applications

• Primary water treatment:
  • Primary coolant purification
  • Treatment of primary coolant blowdown
  • Control of reactor coolant chemistry (removal of excess ⁷Li, potassium, or ammonium)
• Fuel pool purification in single bed VVER systems (oxidative conditions)
• Rad waste treatment and decontamination (removal of radioactive cations such as ¹³⁷Cs and cobalt isotopes)
• PWR steam generation blowdown (APG)

Hydraulic Characteristics

Estimated bed expansion and pressure drop are provided in graphical form (Figures 1 and 2) as a function of backwash/service flowrate and temperature. These figures are valid at the start of the service run with clean water.

• Backwash Expansion (Figure 1) Temperature: 10 – 60°C (50 – 140°F)
• Pressure Drop (Figure 2) Temperature: 10 – 60°C (50 – 140°F)

Product Stewardship

DuPont emphasizes product stewardship, assessing safety, health, and environmental information to protect public health and the environment. Customers are encouraged to review manufacturing processes and applications to ensure appropriate use.

WARNING: Oxidizing agents such as nitric acid can attack organic ion exchange resins, potentially leading to degradation or violent exothermic reactions. Consult knowledgeable sources before using strong oxidizing agents.
