In-situ measurement of zircaloy corrosion rate in high temperature, high pressure water

Technical Report:

Abstract

In-situ measurement of corrosion rate of Zircaloy-4 was tested by applying AC-impedance method in 300degC water in a static autoclave. Impedance data of surface oxide layer of sample were obtained by the Frequency Response Analysis Method and converted into the corrosion rate, and were compared with a theoretical prediction. The results led to the conclusion that the present method permits in-situ measurement of the corrosion rate. It was also found that degradation of water quality affects the data to a considerable extent, and that the impedance data indicate the property change of the double-layer structure of oxide.
