The crevice former which does not release anion impurities (e.g. Cl-) for SCC (Stress Corrosion Cracking) initiation experiment in simulated boiling water reactor water environment has been ev aluated. The creviced bent beam tests of sensitized stainless steel with using the crevice condition as an experimental parameter were carried out. Even SCC occurred at the part of specimen su rface which tested with only the spacer (no crevice former), it has been difficult to obtain the reproducible result. SCC ini...
