Scope and Objectives
The Working Group shall support improved uses of Probabilistic Safety Assessment (PSA) in risk-informed regulation and safety management through the analysis of results and the development of perspectives regarding potentially important risk contributors and associated risk-reduction strategies. The Working Group shall address PSA methods, tools, and data needed to provide this information.
The main objective of the Working Group on Risk Assessment (WGRISK) is to advance the PSA understanding and to enhance its utilisation for improving the safety of nuclear installations, for improving the operation and the design of nuclear installations and for increasing the regulatory effectiveness through risk-informed approaches. In order to achieve this objective, the Working Group shall:
- Report to the Committee on the Safety of Nuclear Installations (CSNI) and assist that Committee with its work.
- Constitute a forum for exchange of information and experience related to risk assessment in NEA member countries. This exchange is not only limited to technical discussions on questions regarding risk analysis approaches, results, insights, applications and interactions with other disciplines and analysis techniques, but it shall also include identifying and prioritising important issues requiring additional research.
- Prepare technical reviews (such as state-of-the-art reports, technical opinion papers, compilations of ongoing efforts, comparison studies etc. as appropriate) of work in all phases of risk assessment to assist further developments and the application of PSA in risk-informed decision making. This work will be done in task groups, whose work will be organised in a project-like manner with outcomes and milestones.
- Sponsor specialist meetings and workshops to further its objectives.
- Collaborate with or assist other CSNI working groups, the Committee for Nuclear Regulatory Activities (CNRA) and other NEA bodies on request. In particular, the WGRISK collaborates with the Working Group on Human and Organizational Factors (WGHOF) on human and organizational contributions to risk, and with the Working Group on on Integrity and Ageing of Components and Structures (WGIAGE) and the Working Group on External Events (WGEV), where those two bodies provide characterisation of seismic and other external hazards, and the WGRISK assesses the risk consequences. The Working Group will also co-operate with other international organisations, aiming among others to avoid duplication of effort.
Interactions
The NEA has established Memoranda of Understanding (MOUs) with a number of organisations – e.g. COG, CRIEPI, EPRI and WANO – to promote international collaboration, particularly in the area of nuclear safety. Accordingly, representatives from these organisations can be invited to participate in the activities of CSNI working groups, consistent with the MOUs, to co-ordinate their work and to avoid unnecessary duplication.
The CSNI sponsors a number of joint safety research projects and expects that the CSNI working groups will promote technical exchanges with relevant projects, and provide technical support as appropriate.
Deliverables
The deliverables of the CSNI and its working groups are technical reports, proceedings of seminars or workshops, final summary reports from joint projects, state-of-the-art reports, and technical or collective opinion papers.
