Research output: Book/ReportReport


The Finnish Research Programme on Nuclear Power Plant Safety 2019–2022, SAFIR2022, continues a series of Finnish national research programmes in nuclear energy that started in 1989. The programmes were initially carried out separately in the fields of operational aspects of safety (YKÄ 1990–1994, RETU 1995–1998) and structural safety (RATU 1990–1994, RATU2 1995–1998, OHA 1995–1998), and then in combined programmes (FINNUS 1999–2002, SAFIR2003–2006, SAFIR2010 2007–2010, SAFIR2014 2011–2014, SAFIR2018 2015–2018). Simultaneously research has been carried out in the national nuclear waste management programmes (KYT2022 runs in parallel with SAFIR2022).

SAFIR2022 consists of four main research areas: (1) Overall safety and systemic approach to safety; (2) Reactor safety; (3) Structural safety and materials; and (4) Research infrastructure. Research has been carried out in 36 projects that are guided by eight reference groups. The research results of the projects are published in scientific journals, conference papers and research reports.

The programme management structure consists of the Management Board, four steering groups managing the research areas, eight reference groups, and programme administration. SAFIR2022 Management Board has representatives of the Radiation and Nuclear Safety Authority (STUK), the Ministry of Economic Affairs and Employment (MEAE), Fennovoima Oy, Fortum, Teollisuuden Voima Oyj (TVO), Technical Research Centre of Finland Ltd (VTT), Lappeenranta-Lahti University of Technology (LUT), Aalto University (Aalto), Tampere University (TAU) and the Swedish Radiation Safety Authority (SSM).

Research in the programme has been carried out by VTT, LUT, Aalto, Finnish Meteorological Institute (FMI), Finnish Institute of Occupational Health (FIOH), TAU and RISE Research Institutes of Sweden. A few subcontractors have also contributed to the work in the projects.

This report has been prepared by the programme management in cooperation withthe project leaders and project staff.
