FILTER FOR REMOVING HIGH-TEMPERATURE COBALT FOR LIGHT- WATER REACTOR

摘要

PURPOSE:To provide the titled filter having an excellent absorbing capacity for a Co ion contained in the reactor water of a light-water reactor without any fear of flowing out by charging an inorganic ion-exchange material having a high Co adsorbing capacity into a vessel of a porous material wherein the material is retained. CONSTITUTION:A powdered metallic oxide 2 of an inorganic ion-exchange material is charged into a vessel 1 made of a porous metal, a porous ceramic material, etc. having mechanical strength, and retained therein to obtain a block which is used as the objective high-temp. Co filter for a light-water reactor. The metallic oxide having a high Co ion adsorbing capacity, for example, contg. =1 kind among SnO2, Fe3O4, MnO2, etc. is used as said metallic oxide. The porous material having =1mum pore diameter is necessarily used for making the vessel 1.
