STRONG BASIC ANION EXCHANGE RESIN, AND DEMINERALIZATION METHOD AND DEMINERALIZATION APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a strong basic anion exchange resin without causing fracture or cracking even if the resin is brought into contact with primary cooling water containing boric acid, and further a demineralization method and a demineralization apparatus using the same.

SOLUTION: There is provided a gel-type strong basic anion exchange resin which is used in primary cooling water having a boric acid concentration of 2500 ppm or more and has a uniformity coefficient of 1.20 or less in a nuclear power plant with a pressurized water reactor, and further a demineralization method and a demineralization apparatus using the strong basic anion exchange resin.
