Technical Report on Material Selection and Processing Guidelines for BWR Coolant Pressure Boundary Piping; Resolution of Generic Technical Activity A-42

摘要

This report updates and supersedes the NRC technical positions established in NUREG-0313, published in July 1977. This report sets forth the NRC staff's revised acceptable methods to reduce the intergranular stress corrosion cracking susceptibility of BWR ASME Code Class 1 and 2 pressure boundary piping and safe end. For plants that cannot fully comply with the material selection, testing, and processing guidelines of this document, varying degrees of augmented in-service inspection and leak detection requirements are presented.
