TECHNICAL BASIS FOR REVISIONS TO SECTION XI APPENDIX C FOR ALLOY 600/82/182/132 FLAW EVALUATION IN BOTH PWR AND BWR ENVIRONMENTS

摘要

This paper provides the technical basis for a revision to the flaw evaluation guidelines of Section XI, to cover Alloy 600 base metal and Alloy 182, 82, and 132 welds, for both PWR and BWR environments. Included are guidelines for residual stress determination, allowable flaw size calculation, and both fatigue and stress corrosion cracking predictions.
