Abstract
A method and an apparatus for performing a condensate demineralization treatment within a condensate demineralization apparatus of a nuclear power plant, which are capable of producing a high-purity treated water containing a low concentration of sulfate ions derived from the TOC eluted from a cation exchange resin. A condensate demineralization method for performing a demineralization treatment of a condensate from a nuclear power plant using an ion exchange resin, wherein the demineralization treatment of the condensate is performed by bringing the condensate into contact with an ion exchange resin bed that includes a mixed bed prepared by uniformly mixing a strongly acidic gel-type cation exchange resin and a strongly basic type 1 porous anion exchange resin having a cross-linking within a range from 1% to 4%.
