Development of a scratch electrode system in high temperature high pressure water
Source abstract
Abstract
Abstract The scratch electrode system in high temperature high pressure (HTHP) water has been built. The design temperature and design pressure of this system are 350 °C and 20 MPa respectively, and the maximum scratch speed is 3.3 m/s. By using this scratch electrode system, the repassivation kinetics of Alloy 690 in high temperature pressurized water with different dissolved hydrogen (DH) at 300 °C is studied. The research results justify that the scratch electrode system is valid and the scratch technique in HTHP water is a new effective and reliable method to study the SCC susceptibility of nuclear materials.
