IPC: B01J35/04
Filed: 1993-11-19
Abstract: PURPOSE: To provide an internal passive catalyst device which operates in the downstream of an air-water separator in the water phase of a pressure vessel of a seething water type nuclear reactor. CONSTITUTION: A catalyst device 48 contains a catalyst substance in such an arrangement that all of the water phase (except a slight amount of leaking water) flowing out of an air-water separator flows as creeping on the surface of the catalyst substance. This surface of catalyst substance decomposes the dissolved hydrogen peroxide into water and oxygen. In case the catalyst substance has such a structure that the base is subjected to a plating or alloy forming process using a water recoupling catalyst (for example, noble metal), the surface of catalyst substance also accelerates the reaction to produce water through recoupling of the dissolved hydrogen and oxygen molecules. This catalyst device is configured so that the pressure drop of a cooling water in the atomic reactor from before to after the reaction remains very small.
