DuPont™AmberLite™ IRN77 HIonExchangeResinis
designed specifically for use in nuclear loops where highest
resin purity and stability are required, and where the "as
supplied" resin must have a minimum of ionic and non-ionic
contamination. These high standards of resin purity enable
plants to achieve reliable and safe production whilst reducing
the need for equipment maintenance and minimizing the
impact of unscheduled outages.
AmberLite™ IRN77 Hisahighcapacity, 8% DVBcationresinusedtoremovecations
for purification and pH control in primary water treatment. It contains a minimum of 99%
of its exchange sites in the hydrogen form. The uniform particle size and the absence of
fine resin beads result in a lower pressure drop compared to conventional resins.

AmberLite™ IRNIonExchangeResinsaremanufactured asnuclear-grade using specific procedures throughout the manufacturing process to keep the inorganic impurities at the lowest possible level. Special treatment procedures are also utilized to remove traces of soluble organic compounds to meet the rigorous demands of the nuclear industry. These high standards of resin purity will help keep nuclear systems free of contaminants and deposits, and prevent increases in radioactivity levels due to activation of impurities in the reactor core. IRN resins are recommended in both non regenerable and regenerable single bed or mixed bed applications where reliable production of the highest quality water is required and where the "as supplied" resin must haveanabsolute minimumofionic and non-ionic contamination.
