NAC Stoller Training includes:

Performance-Based Nuclear Fuel Manufacturing Oversight in a 2.5 day seminar provides training on fabrication techniques and the assessment of them in consideration of design, materials, performance, reliability and integrity. The training presents methods and approaches for the development of a prioritised (graded), engineering-based, technical oversight program. This training helps utility oversight staff to identify and focus on the most important aspects of manufacturing, including statistical techniques appropriate for the assessment of manufacturing processes and inspections.


Regular Nuclear Fuel technical products from NAC Stoller include the COPAG (Core Performance Assessment Group) program. COPAG membership includes utilities that operate a diversity of reactor types and fuel designs in Asia, Europe, and the United States. They sponsor independent analyses by NAC Stoller of critical contemporary issues in nuclear fuel design, manufacturing, operation, performance and reliability. COPAG provides members with highly organised vendor and industry information, including expert analysis on nuclear fuel and core components.
