The Nordic PSA Group NPSAG was founded in December 2000 by the nuclear utilities in Finland and Sweden. In addition, the Swedish Radiation Safety Authority (SSM) participates as an observer, and also takes part in the funding of many of the projects.
NPSAG is a common forum for discussion of issues related to probabilistic safety assessment (PSA) of nuclear power plants, with focus on research and development needs. The group follows and discusses current issues related to PSA nationally and internationally, as well as PSA activities at the participating utilities. The group initiates and co-ordinates research and development activities and discusses how new knowledge shall be used.
Over the years, international contacts have increased, especially with partners in Europe. This is in line with the group’s aim to create a common and lasting basis for the performance of PSA and for risk informed applications of PSA in Europe.
