AmberLite IRN67

Summary

Product identification

• Product Name: AMBERLITE™ IRN67 Ion Exchange Resin
• Type: Nuclear-grade, Gel, Acrylic, Weak Base Anion Exchange Resin
• Manufacturer: DuPont

Description

AMBERLITE™ IRN67 is an ion exchange resin specifically designed for nuclear loops requiring high purity and stability, with minimal ionic and non-ionic contamination in its supplied form. It is particularly suited for VVER fuel pool purification systems where organic matter is a concern, offering enhanced resistance to organic fouling compared to standard resins.

Applications

• Fuel pool purification in single bed VVER systems with high organic load.

Purity

Manufactured as nuclear-grade with specific procedures to minimize inorganic impurities and remove soluble organic compounds, meeting the stringent demands of the nuclear industry. Recommended for non-regenerable and regenerable single bed or mixed bed applications requiring high-quality water with minimal contamination.

Hydraulic Characteristics

Estimated bed expansion and pressure drop as a function of backwash/service flowrate and temperature are provided in figures within the original document. These estimations are valid at the start of the service run with clean water and a well-classified bed.

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