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.

Seismic Probabilistic Safety Assessment for Nuclear Facilities
Nuclear Energy Agency
Seismic probabilistic safety assessment (SPSA) is a systematic method for examining and evaluating the risk from earthquake-initiated accidents. The significant advances in the area of SPSA since the initial publication in 2002 of Technical Opinion Paper No. 2: Seismic Probabilistic Safety Assessment for Nuclear Facilities by the OECD Nuclear Energy Agency have prompted its revision. The objective of this report is to provide the up-to-date international view on the state of the SPSA as it is currently being applied, including a description of the main elements of SPSA. While the uncertainties associated with seismic hazard and the determination of seismic failure probabilities are typically large, the inclusion of SPSA in a risk assessment results in a more complete risk picture, and thus enables more meaningful PSA applications.
