N2 - 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 four years of work, but focuses on
the finalization of a Nordic Level 3 PSA Guidance
Document which has been worked upon mainly during
calendar years 2015 and 2016. Other activities that has
been conducted, and provided valuable input to the
Guidance Document, are an Industrial Survey, a study of
potential Risk Metrics, a summary of Regulations &
Standards, and two Pilot Studies (one Swedish and one
Finnish). 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. During the project, targeted
discussions between consultancies, utilities, regulators,
and insurance companies on the subject of Level 3 PSA
have taken place and at the end of each years working
period a seminar has been arranged. The working group has
also been engaged in international activities surrounding
Level 3 PSA, i.e. the development of the IAEA Level 3 PSA
TECDOC and the ANS/ASME Level 3 PSA Standard through the
2016 continuation of the project.
All project reports are provided as appendices to this
final report.
