|Report Title:||Addressing off-site consequence criteria using Level 3 PSA - Phase 3 Status Report from the NKS-R L3PSA|

|Abstract:||The goal of this project is to further Nordic understanding of the potential for Level 3 PSA to determine the influences and impacts of off-site consequences, the effectiveness of off-site emergency response, and the potential contributions of improved upstream Level 1 and Level 2 PSAs.
This report summarizes the developments from the three years of work, but focuses on the developments during calendar year, 2015. The two primary activities over the third year of the project were the continuation of the pilot studies and the development of a guidance document. Complete discussion on each of the tasks, are attached as appendices to the report.
During the project, targeted discussions between consultancies, utilities, regulators, and insurance companies on the subject of Level 3 PSA have taken place. In the first years of the project the working group focused on participation in ongoing international activities, the development of an international industrial survey, and a study of appropriate risk metrics. During 2014 and 2015 two pilot studies. The main objective of the pilot studies was to gain practical experience that, together with insights from the other tasks included in the project, could be transferred to recommendations into a final guidance document directed to satisfy the needs for the Nordic nuclear power industry.
During 2015, the pilot projects were completed and the guidance document was completed along with the project stake holders. The working group will remain engaged in international activities surrounding Level 3 PSA, the development of the IAEA Level 3 PSA TECDOC and the ANS/ASME Level 3 PSA Standard through the 2016 continuation of the project.
