Environmental effects on components: A nonmandatory appendix for ASME Section III
- Science Applications International Corp., Germantown, MD (United States)
A nonmandatory appendix is being developed, by an ASME task group on environmental effects, to provide guidance on potential light water reactor service degradation mechanisms not explicitly covered by design requirements in Section 3 of the ASME Boiler and Pressure Vessel Code. Categories of degradation mechanisms addressed by the appendix include corrosion, embrittlement, fretting and wear, thermal fatigue, dynamic loading, and creep. For each damage mechanism, the appendix will address: description and experience; material selection, treatment and testing; operation and design Limitations; and mitigating actions and remedies. Awareness of these damage mechanisms is essential to planning in-service inspection and plant life extension activities. This paper presents the background for the nonmandatory appendix and discusses its expected content.
