Use of nuclear energy must be safe

The use of nuclear energy must not cause injury to people, or damage to the environment or property. This basic priority of the use of nuclear energy is laid down in the Nuclear Energy Act (990/1987) and it applies to all use of nuclear energy in Finland.

Electricity generation in nuclear power plants is based on a self-supporting chain reaction. The most important task in nuclear safety supervision is to ensure that this chain reaction is kept under control and to prevent any harmful effects of the radiation of the radioactive substances arising from this chain reaction. It is clear that safety must also be ensured at the various stages of the handling, transport and use of the nuclear fuel and in nuclear waste management.

On 16 May 2011, the Radiation and Nuclear Safety Authority submitted a report to the Ministry of Employment and the Economy on the preparedness of Finnish nuclear power plants for floods and other extreme natural phenomena. Later the same year, the Radiation and Nuclear Safety Authority carried out the national stress tests and the stress tests required by the EU on Finland’s nuclear power plants.

The working group reviewing nuclear energy competence in Finland published its report in March 2012.

In Finland STUK – Radiation and Nuclear Safety Authority Finland, operating under the Ministry of Social Affairs and Health, is responsible for the supervision of nuclear safety.

Development of the principles governing nuclear safety and the methods for implementing it is largely based on extensive international cooperation. This intensive cooperation already started in the middle of the 20th century. The International Atomic Energy Agency (IAEA), which belongs to the UN family of organisations, and NEA (Nuclear Energy Agency of the OECD) play an important role in this cooperation.
