10 CFR 50 Appendix J Program Training

The course is comprehensive with respect to programmatic aspects of 10 CFR 50 Appendix J, provides a specific focus on current industry developments such NEI 94‐01 Rev 3A, and now incorporates a
“hands‐on” Local Leak Rate Testing (LLRT) demonstration where students perform valve lineups, simulate troubleshooting and collect leak rate results using an LLRT mock‐up complete with associated test equipment.


Managing a power plant’s Appendix J Program requires talents from and interfaces with various disciplines, practical ability and a good understanding of the regulatory requirements. The course is designed to provide an initial conceptual overview of Appendix J and the regulatory documents that provide implementation guidance and requirements, followed by comprehensive and in‐depth practical application of those requirements. In addition, discussions related to specific plant activities, that, when implemented facilitate program incorporation of industry best practices, are ongoing throughout the course. The course curriculum has been designed to meet the student’s needs regardless of experience level.
