Key points from presentations, Key points from presentations, posters and panel discussionsposters and panel discussions

• Many plants world-wide are reaching the end of their design life and will be entering long term operation (LTO)

• Economic, political and regulatory uncertainties complicate power plant decisions and efforts to pursue continued LTO

• IAEA standards (such as PSR and SRS 57) and missions have been found to be very useful by many plants and countries to demonstrate safe plant operation during LTO

• Sufficient lead time is needed for preparation of documentation to demonstrate safe LTO, review by the regulator, and implementation of ageing management programmes

• Ageing management is a living activity that requires continued updating based on programme results and consideration of international operating experience

• Significant technical issues related to LTO and plant operation beyond 60 years need to be researched and ageing management solutions identified

International Atomic Energy Agency4

• Real-time sharing of international operating experience is vital to ensure continued safe LTO, considering ageing management findings and precursors

• Development of additional research findings to address technical issues for LTO, maybe from harvested materials

• Enhancements and improvements to IAEA standards and missions – is there a need for more closely coordinated IAEA activities (e.g., standards and missions)?

• Communication packaging of technical solutions that assure safe plant operation in LTO to support public conversations and confidence – more use of IAEA peer review missions?
