Application of Electrochemical Techniques for Performance Evaluation of Nuclear Material Used in Supercritical Water Reactors
Performance of nuclear material is one of the most important issues in the design, development,availability and safety of supercritical water reactors. Nuclear material suffers fromintergranular or irradiation-assisted stress corrosion cracking, flow accelerated corrosion,corrosion fatigue and hydrogen damage in supercritical water environment. A number ofphysical and chemical analysis techniques (including electrochemical, surface analysis,mechanical analysis and gravimetry) are employed to study the behavior of nuclear material insuch environments. Electrochemical techniques, in particular, allow a rapid, in-situ, mechanisticinvestigation of the degradation process of nuclear material. We will review the applications ofelectrochemical techniques to evaluate the performance of nuclear material candidates forsupercritical reactors. These include open circuit potential measurement, polarization techniques,electrochemical impedance spectroscopy, electrochemical frequency modulation andelectrochemical noise. In particular, the application of the electrochemical noise in a supercriticalwater environment will be highlighted.
