NAFCS – Nordic Working Group for CCF Analysis

Project Manager, NPSAG: Ralph Nyman
Project Manager, External: Gunnar Johanson
Start Year: 2000
Finish Year: 2004
The Swedish Radiation Safety Authority (SSM) Regulatory Code SSMFS 2008:1 includes requirements regarding the performance of probabilistic safety assessments (PSA), as well as PSA activities in general. Therefore, the follow-up of these activities is part of the inspection tasks of SSM. According to SSMFS 2008:1, the safety analyses shall be based on a systematic identification and evaluation of such events, event sequences and other conditions which may lead to a radiological accident.

The research report “Dependency Defence and Dependency Analysis Guidance” has been developed under a contract with the Nordic PSA Group (NPSAG), with the aim to create a common experience base for defence and analysis of dependent failures i.e., Common Cause Failures, CCF.
