PURPOSE:To purity directly a nuclear reactor coolant water being high- temperatured and highly pressurized, by covering a surface of a filter with an ion adsorbing material consisting of composite oxides, 50-70wt.% of an iron or a nickel and 30-50wt.% of a titanium. CONSTITUTION:A surface of a filter 6 is covered by an ion adsorbate consisting of composite oxides, 50-70wt.% of an iron or a nickel and 30-50wt.% of a titanium. And a high-temperatured and highly pressurized cooling water flowing in from an inlet nozzle 3 reaches the filter 6 which is covered with an ion adsorbate 8 as shown by arrows in the figure, contacts with the adsorbate 8 covering the surface of the filter 6 and ionized corrosion products are adsorbed and removed. Subsequently, during a process flowing through a sintering metal porous pipe with small diameter, particulate corrosion products are filtered and removed. Through these processes, the cooling water passing through the filter 8 covered with the adsorbate 8 is removed of ionized and particulate corrosive products contained in it and finally flows out from an outlet nozzle 4. |
