Regulatory Oversight of Ageing Management and Long Term Operation Programme of Nuclear Power Plants

Member States are extending the operating lifetime of nuclear power plants, so safety oversight of aging management and long-term operation (LTO) is becoming increasingly important. This Safety Report provides technical and practical information based on existing regulatory approaches and practices and the application of IAEA Safety Standards. It is intended for nuclear safety authorities, operating organizations, licensees, manufacturers, designers, and technical support organizations considering authorization for LTO.

As Member States aim to prolong the operational lifespan of nuclear power plants beyond their initial licensing, the oversight of aging management and long-term operation (LTO) has assumed paramount significance. In this Safety Report, we present a comprehensive compilation of technical and practical insights derived from the existing regulatory frameworks and practices of Member States. Additionally, we explore the application of the IAEA Safety Standards, which serve as guiding principles for LTO. This report encompasses a range of requirements and preconditions set by the regulatory body for LTO, the authorization processes employed, and the regulatory practices and documentation necessary to prepare for and execute LTO.

The primary audience of this report includes nuclear safety authorities, operating organizations, licensees, manufacturers, designers, and technical support organizations actively engaged in considering authorization for LTO of nuclear power plants. By delving into these critical aspects, this Safety Report aims to foster a deeper understanding of the safety considerations and requirements associated with extending the operational life of nuclear power facilities.

The significance of LTO cannot be overstated, as it enables nuclear power plants to continue generating electricity while minimizing the environmental impact and associated risks. However, the process requires meticulous planning, rigorous evaluation, and adherence to the highest safety standards. This report serves as a valuable resource for stakeholders involved in LTO endeavors, providing them with the necessary information and guidance to ensure the safe and successful implementation of long-term operations.

In conclusion, as Member States pursue the extension of nuclear power plant operating lifetimes, the oversight of aging management and LTO has become an essential component of ensuring nuclear safety. This Safety Report offers a comprehensive framework for understanding and implementing LTO, drawing upon the expertise and experiences of Member States and the IAEA Safety Standards. By leveraging this knowledge, we can work towards a future where nuclear power plants continue to contribute to our energy needs while maintaining the highest levels of safety and security.
