A method for purifying water in a spent fuel pool in a nuclear power plant, the method including passing the water at a linear flow velocity of 50 m/h or less through a purification apparatus. The apparatus includes an ion exchange resin layer and a metal-doped resin layer laid at a bed height of 2 cm or more on a surface layer of the ion exchange resin layer. The method includes contacting the water with the metal-doped resin layer to decompose a pro-oxidant contained in the water and subsequently contacting the water with the ion exchange resin to produce purified water.
