NKS-R Level 3 PSA seminar
20th January 2015, ĹF, Frösundaleden 2, 169 99 Solna, Sweden
The objective of this seminar is to present and discuss the progress of the NPSAG/NKS Level 3 Probabilistic Safety Assessment Project and to receive feedback from participants for future and ongoing tasks.
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 second 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, ĹF, and VTT. The project is planned to continue through 2015 with the final result of the project being a guidance document on Level 3 PSA that will portray Nordic perspectives on the subject.
