...Abstract A simplified method is proposed for modeling the chemistry and potential distribution in a stress corrosion crack in sensitized stainless steel in boiling water reactor (BWR) coolant environments. The model is based on an assumption that only those species that are present at the largest...

...Abstract Stress corrosion cracking (SCC), especially in existing boiling water reactor (BWR) components, is most effectively accomplished by reducing the corrosion potential. This was successfully demonstrated by adding hydrogen to BWR water, which reduced oxidant concentration and corrosion...
