More than two‑thirds of the world’s 400+ nuclear reactors are now over 30 years old—making long‑term operation (LTO) a critical pathway for delivering reliable, carbon‑free electricity at scale.
In a recent Energy Central article, Garry Young highlights insights from International Atomic Energy Agency (IAEA) TECDOC‐2117 on good practices and lessons learned from global LTO efforts and the role of EPRI research in advancing these approaches.
Electric Power Research Institute (EPRI) science‑based frameworks, including Materials Degradation Matrices and Issue Management Tables, are referenced throughout the report for enabling:
• Predictive understanding of materials degradation
• Integrated, risk‑informed aging management programs
• Strategic modernization and long‑term asset planning
These approaches are helping utilities extend plant lifetimes safely and cost‑effectively, often to 60, 80 years and beyond, while maintaining strong safety and performance.
As the industry looks ahead, continued collaboration and applied research will be essential to address late‑life material challenges, workforce continuity, and evolving system needs.
