Water environment improvement (ex. Hydrogen Water Chemistry (HWC)) is carried out for Stress Corrosion Cracking (SCC) mitigation in some of BWR plants. Japan Nuclear Technology Institute (JANTI) has the guideline on the inspection programs based on effectiveness of environmental SCC mitigation technique for BWR core internals. The guideline provides the crack growth rate (CGR) under HWC. Although CGR is defined by ECP (electroch emical corrosion potential), a dealing of evaluation of ECP and the HWC avail...
