Abstract
Particles of an ion exchange resin are brought into contact with water in a water circulation system in a power plant for capturing corrosion products and other impurities and are removed after reaction with the corrosion products and the other impurities from the water circulation system, the water circulation system including a reactor vessel or a steam generator connected thereto for generation of steam, a steam turbine driven by the steam, a condenser for condensing the steam from the steam turbine and a condensate cleaning filter for cleaning condensate formed in the condenser, as well as one or more pumps for effecting the water circulation and returning cleaned condensate to the reactor vessel or the steam generator. The ion exchange resin is supplied successively to the condensate in the water circulation system at a sufficient distance from the condensate cleaning filter for the ion exchange resin, when being collected in the form of layers in the condensate cleaning filter, to have been substantially exhausted by reaction with corrosion products and other impurities during the movement of the water from the supply point for the ion exchange resin to the condensate cleaning filter. The exhausted ion exchange resin collected in the condensate cleaning filter is removed after a certain period of collection from the condensate cleaning filter.
