NKS-R Level 3 PSA seminar

28th January 2016, ÅF, Frösundaleden 2, 169 99 Solna, Sweden



The objective of this seminar is to present and discuss the NPSAG/NKS Level 3 Probabilistic Safety Assessment Project and to receive feedback from participants on the Guidance Document and the development of project conclusions.



Interest in Level 3 off-site consequence probabilistic safety assessment (PSA) has increased in the Nordic region, which is consistent with renewed interest in Level 3 PSA throughout the world. The goal of the project is to assess the capabilities and applications of Level 3 PSA in order to further understanding of the influences and impacts of off-site consequences, mitigative actions, and to indicate any potential impacts on Level 1 and particularly Level 2 PSA to consider when performing Level 3 PSA. The project is in its third year, and is co-financed by NKS, NPSAG and SAFIR (Finnish research on NPP safety), and is being performed by a consortium of Risk consultancies including Lloyd's Register Consulting, Risk Pilot, ÅF, Vattenfall and VTT. The final result of the project being a guidance document on Level 3 PSA that will portray Nordic perspectives on the subject. This seminar will present the findings from the project.
