The first part of this course covers the fundamental design rules, regulations, and practices for ASME III and ASME B31 piping systems in nuclear power plants. The second part of the course provides a guide for the evaluation of degraded and non-conforming conditions through case studies, using ASME XI and the corresponding NRC regulations and precedent. The course concludes with a review of repair options for safety-related and non-safety piping systems and components.
