Nuclear safety

STUK supervises nuclear safety in Finland. The license holder is responsible for the safety of nuclear energy use, but STUK sets the safety requirements and oversees their compliance. STUK's supervision includes nuclear facilities, nuclear materials and nuclear waste.

Current issues

The Radiation and Nuclear Safety Authority’s new decision on the application of the nuclear safety guide YVL A.2 harmonises STUK’s requirements concerning the precautionary action zone and emergency planning zone of nuclear power plants.

The Radiation and Nuclear Safety Authority (STUK) is preparing for the construction of new nuclear power plants which deviate from the current solutions in Finland. As part of this work, it also assesses the nuclear power plant plans of Finnish companies.
