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.

Better Nuclear Plant Maintenance: Improving Human and Organisational Performance

Nuclear Energy Agency

Errors during maintenance and periodic testing are significant contributors to plant events. These errors may not always be revealed by post-maintenance tests and may remain undetected for extended periods until the affected system is called upon to function. It is therefore important that the plant maintenance process take into account the potential impact of human and organisational errors, and that it incorporate suitable measures to minimise the potential for such errors.

The NEA Committee on the Safety of Nuclear Installations (CSNI) and its Working Group on Human and Organisational Factors organised an international workshop to discuss the role of human and organisational performance on maintenance. This technical opinion paper represents the consensus of specialists on human and organisational factors in NEA member countries on commendable practices and approaches to dealing with nuclear power plant maintenance. It sets out a framework for including a systematic consideration of human and organisational factors in the plant maintenance process. The paper should be of particular interest to nuclear safety regulators and nuclear power plant operators.
