LEWATIT® MonoPlus SM 1015 KR-7Li

Summary

Product identification

Lewatit® MonoPlus SM 1015 KR-7Li is a ready-to-use mixed bed, premium grade, and purified ion exchange resin designed to meet nuclear industry specifications. It comprises strongly acidic gel-type cation resin in 7Li⁺ form and strongly basic (type I) gel-type anion exchange resin in a fully regenerated form.

Applications

This product is particularly suitable for:

• Polishing in primary sections as a mixed bed component
• Decontamination of circuits in nuclear reactor plants
• Treatment of primary coolant (e.g., in pressure water reactors)
• Purification of steam generator blowdown (with Levoxin, ethanolamine, or morpholine)
• Removal of activated cleavage or corrosion products, including mechanical filtration of suspended impurities
• Polishing in Candu reactor systems (HTS, ESC, RCW)
