Discussion on “Electrochemical Potential Measurements Under Simulated BWR Water Chemistry Conditions” Available to Purchase

In the following article, D.D. Macdonald^* discusses “Electrochemical Potential Measurements Under Simulated BWR Water Chemistry Conditions,” by C.C. Lin,^** F.R. Smith,^** N. Ichikawa,^*** and M. Itow,^*** which was published in Corrosion 48,1 (1992): pp. 16-28. Lin replies in the section following Macdonald's discussion.

In the above-referenced paper, Lin et al.¹  report measurements of the corrosion potentials (the electrochemical potential or ECP) of types 304 and 316 SS in simulated boiling water reactor (BWR) heat transport environments at 270°C. These studies were carried out under normal water chemistry (NWC) and hydrogen water chemistry (HWC) conditions and/or in the presence of various salts, including Na₂SO₄, NaOH, H₂SO₄, ZnSO₄, Cu(NO₃)₂, and CuSO₄. On the basis of this work, the authors conclude that: “Without chemical additives, the effect of water flow rate...
