This white paper presents a comprehensive evaluation of the continued applicability of NUREG-1829 and the Transition Break Size (TBS) framework in light of nearly two decades of additional operating experience, research, and advancements in materials management within the U.S. commercial nuclear power industry. It demonstrates that the existing suite of industry programs, including the NEI 03-08 Materials Initiative, Risk-Informed Inservice Inspection (RI-ISI) methodologies and augmented inspection protocols provide a robust and proactive foundation for managing materials degradation in reactor coolant pressure boundary components.
