Summary of Session 4: Operating Experience 1 Abdul Hamid Akbar IAEA International Conference on Operational Safety Vienna International Centre June 2015

International Atomic Energy Agency 2 Key points from presentations, posters and panel discussions Performance Improvement (Palo Verde story) Strong leadership and employees engagement in continuous improvement Effective self-assessment process and benchmarking to support Long-term focus – Safety Leadership training to all staff – Everyone is a Leader Reporting and Use of OE (IAEA, WANO) Sharing of OE among MS to prevent similar events Feedback on the use of operating experience Timely involvement of Newcomers

International Atomic Energy Agency 3 Key points from presentations, posters and panel discussions Event example from Korea Procedure deficiency leading to failure of redundant measurements to monitor integrity barrier Aging of checking source for N16 detectors and their operability verification Weaknesses in FME programme HF management in Aviation Crew resource management to develop strong leadership capabilities and non-technical skills to prevent errors Just Culture – key element in risk management Roadmap to proactive/ predictive safety culture

International Atomic Energy Agency 4 Key points from presentations, posters and panel discussions Chemical Industry experience Risk of hydrogen detonation - high even at concentrations considered to be “safe” Prevention of hydrogen accumulation – venting and catalytic oxidation Post-operational phase (Germany experience) Risks created by specific conditions in post-operational phase Examples - modifications of systems, modified operation modes, increased decontamination, reduction of personnel including shift staff, staff training etc.

International Atomic Energy Agency 5 There is a need to improve sharing of important OE by MS through IRS. The actions taken after events should be considered in back-fitting programmes in other MS. Feedback from MS on how important lessons learned were used to prevent similar issues needs to be improved. MS are encouraged to develop effective self- assessment programmes supported by strong leadership, creating positive attitude to OE and engaged employees in continuous improvement. MS are encouraged to benchmark with non-nuclear organizations (e.g. aviation, chemical industry etc) with the objective to share OE and improve operational safety Potential areas for further improvements

International Atomic Energy Agency 6 The design of future reactors should also make optimal use of accumulated OE. Good practices should be identified and shared to serve as examples. The effectiveness of OPEX on regulatory oversight needs to be more strengthened. The international OE feedback systems should be supported by an internationally agreed mechanism for coordination and guidance. There is a need to continuously improve the effectiveness of OE by enhancing RCA and monitoring of corrective actions. Potential areas for further improvements

International Atomic Energy Agency …Thank you for your attention! 7
