Abstract
An apparatus for controlling dissolved oxygen concentration in primary and secondary cooling water in boiling water and pressurized water atomic reactors is disclosed. The apparatus contains an electrolytic cell having an anode chamber and a cathode chamber separated from one another by a diaphragm of a solid polymer electrolyte membrane. The diaphragm contains: (a) an ion exchange membrane and (b) a pair of multilayered electrodes chemically plated to both surfaces of the ion exchange membrane. The electrolytic cell is operatively connected to a circular route for cooling water in the reactor, and hydrogen gas generated through electrolysis of deionized water in the cathode side of the cell is introduced into the circular route for the cooling water to control the dissolved oxygen concentration of the cooling water.
