METHOD AND DEVICE FOR CONDENSATE DEMINERALIZATION

PROBLEM TO BE SOLVED: To provide a method and device for condensate demineralization by which high-purity treated water with low concentrations of suspended corrosion products and a sulfate ion. SOLUTION: The method for condensate demineralization to process condensed water from a BWR nuclear power generation plant using an ion-exchange resin layer in which the ion-exchange resin layer processing the condensed water comprises a cation resin layer as the outer-most part, a layer mixed with a cation and anion resins as the intermediate part and an anion layer as in which the cation resin, or a layer mixed with a cation and anion resins as the outer-most part in which a ratio of the cation resin to the anion resin is not less than 2, a layer mixed with a cation and anion resins as the intermediate part in which a ratio of the cation resin to the anion resin is between 0.5 to 2, and a layer mixed with a cation and anion resins as the bottom part in which a ratio of the cation resin to the anion resin is not greater than 0.5.
