Oxygen suppression in boiling water reactors. Quarterly report 4, July 1-September 30, 1978
Boiling water reactors (BWR's) generally use high purity, no-additive feedwater. The primary recirculating coolant is neutral pH, and contains 100 to 300 ppB oxygen with stoichiometrically related dissolved hydrogen. However, this oxygen concentration increases the susceptibility of austenitic stainless steel to intergranular stress-corrosion cracking (IGSCC) when the other requisite factors, stress and sensitization, are present. Thus, reduction or elimination of the oxygen in BWR water may preclude cracking incidents. The objective of this program is to perform an in-depth engineering evaluation of the potential suppression additives supported by critical experiments where required to resolve substantive uncertainties. On the basis of the engineering evaluation, the optimum oxygen suppression approach will be selected and a specific BWR plant recommended for an extended plant demonstration experiment.
