CSNI Technical Opinion Papers
Nuclear Energy Agency
Nuclear Energy Agency (NEA) Technical opinion papers (TOPs) are the summary consensus of experts for a particular topic in the field of nuclear safety. They are the result of work carried out under the aegis of the Committee on the Safety of Nuclear Installations (CSNI). The first TOP was released in 2002. Topics addressed in TOPs have included: Fire Probabilistic Safety Assessment (PSA); Recurring Events; Human Reliability Analysis in PSA for Nuclear Power Plants; Managing and Regulating Organisational Change in Nuclear Installations; Living PSA and its Use in the Nuclear Safety Decision-making Process; Development and Use of Risk Monitors at Nuclear Power Plants; Level-2 PSA for Nuclear Power Plants; The Role of Human and Organisational Factors in Nuclear Power Plant Modifications; Better Nuclear Plant Maintenance: Improving Human and Organisational Performance; Research on Human Factors in New Nuclear Plant Technology; Loss-of-Coolant Accidents Criteria Basis and Test Methodology; Nuclear Licensee Organisational Structures, Resources and Competencies: Determining their Suitability; Ageing Management of Nuclear Fuel Cycle Facilities; and Defence in Depth of Electrical Systems.

Recurring Events
Nuclear Energy Agency
Feedback on operating experience from nuclear power plants is intended to help avoid occurrence or recurrence of safety-significant events. Well-established feedback systems exist on the national and international levels. One such example is the Incident Reporting System (IRS), jointly operated by the International Atomic Energy Agency (IAEA) and the OECD Nuclear Energy Agency (NEA).
This technical opinion paper presents the international systems used to collect operating experience, the role of recurring events within them, examples of recurrence and ideas about how to improve the situation. It is expected that managers in both nuclear utilities and regulatory bodies, persons involved in operating experience feedback and analysis, inspectors and technical support organisation staff will be interested in this publication.
