ABSTRACT:
An improved boiling water nuclear reactor and method for preventing intergranular stress crack corrosion in the recirculation line of the reactor system where recirculation line coolant water containing dissolved oxygen is diverted from the recirculation loop, hydrogen gas is introduced into the recirculation loop coolant water and the hydrogen-containing recirculation loop coolant water is contacted with a catalyst to enhance reaction of the hydrogen gas with the dissolved oxygen. The deoxygenated recirculation loop coolant water is then returned to the reactor vessel for passage through the core thereof. The hydrogen gas may be added in a stoichiometric amount to remove the dissolved oxygen or in a slight excess so as to suppress radiolysis in the reactor core.
