Localized corrosion of pressure vessel steel in a boiling water reactor cladding flaw
Abstract
Stress corrosion cracking (SCC) tests performed inoxygenated high-temperature water with compact tension(CT) specimens have indicated that very smallconcentrations of chloride accelerate significantly therate of crack growth in low-alloyed steels (LAS). In thepresent work, the electrochemical conditions in a CTspecimen are simulated and compared to those in acladding flaw. The Cl- and Fe2+ concentrations and thecorrosion potential are predicted to be significantlyhigher in the crevice of a CT specimen than in thecladding flaw, whereas pH is significantly lower. Thus, amuch more aggressive environment is established in the CTspecimen. General corrosion rates of LAS in the presenceof chloride, estimated by impedance spectroscopy, weightloss and thickness of oxide films, increase significantlyat potentials more positive than the corrosion potential.In addition, slow strain rate tests showed susceptibilityto SCC at E > -0.3 V vs. SHE, the tendency increasingwith potential. It can be concluded that due to thehigher potential in the crevice of CT specimen,determined by a more aggressive chemistry, the conditionswithin it are not representative for a realistic claddingflaw.
