Abstract

PURPOSE: To prevent from corrosion of reactor material during shutdown or start- up by removing previously dissolved oxygen and carbonic acid gas during the shutdown period or before the start-up of atomic power plant.
CONSTITUTION: For example, for system where reactor of reactor 1 is circulated by re-circulation pipe 2, a part of water being drawnoff by reactor cleaning system pipe 3, and returning to the reactor by passing through cooler 4, filter 5 and desalting unit 6, deaerator 7 is provided for the front of said desalting unit 6, hydrogen gas cylinder 8 being located at the front of deaerator 7, and feeding hydrogen gas to maintain approximately 1 ppm by passing flowmeter 9. In this case, deaerator 7 comprises ion exchange resins layer 10, oxidation catalizer layer 11, the layer 10 allowing to remove bicarbonade ion by carbonic acid gas in the air, which is dissolved in water, distributing umiformly supplied hydrogen gas to form water bonding dissolved oxygen with hydrogen within other layer 11. Further 12 denotes exhaust gas pump. 13 denotes a bypass valve
