Ydinenergian käytön on oltava turvallista eikä siitä saa aiheutua vahinkoa ihmisille, ympäristölle tai omaisuudelle. Ydinvoimalaitoksen turvallisuudesta vastaa aina voimayhtiö. STUKin tehtävä on valvoa kaikkea toimintaa laitosten suunnittelusta toiminnan lopettamiseen.

STUK: The third nuclear reactor of Olkiluoto received the fuel loading permit

26.3.2021 klo 09:40

The Radiation and Nuclear Safety Authority (STUK) has granted a fuel loading permit for Teollisuuden Voima Oyj’s (TVO) Olkiluoto 3 nuclear power plant unit (OL3) on 26 March 2021.

STUK states in its fuel loading permit that OL3 meets the safety requirements set for it and its security and emergency arrangements and procedures are sufficient in order to load nuclear fuel in the reactor. STUK also states that the control necessary to prevent the proliferation of nuclear weapons has been appropriately arranged and that the nuclear facility licensee has arranged, in the manner provided, indemnification regarding liability in the event of   nuclear damage.

Project Manager Essi Vanhanen from STUK states that when the fuel loading begins, OL3 will be regarded as an operating nuclear power plant and STUK’s oversight will continue as oversight of a nuclear power plant in use. TVO, as the licensee, is responsible for ensuring that the plant is safe and used in accordance with the safety requirements.

The fuel loading is followed by a commissioning phase lasting several months during which TVO will continue to test the plant. There is a number of tests that require fuel to be loaded in the reactor to show that the systems work correctly. TVO has planned that regular electricity generation will start in February 2022.

According to Project Manager Essi Vanhanen, STUK oversees the commissioning phase closely and TVO needs an authorization from STUK before advancing from one commissioning phase to another.

Teollisuuden Voima Oyj has built the Olkiluoto 3 nuclear power plant in Olkiluoto, Eurajoki. Measures taken by the Radiation and Nuclear Safety Authority during the construction of the Olkiluoto 3 nuclear power plant can be divided into six largely overlapping phases. Safety assessment, surveillance and test runs can be placed on the construction timeline as follows: Phase 1: Initial safety assessment, duration approximately two years, implementation in 2000-2002. Phase 2: Regulatory control of planning, duration approximately 11 years, implementation in 2003-2014. Phase 3: Regulatory control of manufacturing, duration approximately 14 years, implementation in 2004-2018. Phase 4: Construction safety assessment, duration approximately 14 years, implementation in 2005-2019. Phase 5: Regulatory control of installation, duration approximately 12 years, implementation in 2007-2019. Phase 6: Test runs, duration approximately 10 years, implementation in 2012-2022. Location of events on the timeline: STUK’s regulatory control at Olkiluoto continues throughout the plant’s entire life cycle, all the way from decommissioning to final disposal.​​​​​​​

STUK valvoo ydinturvallisuutta

Ydinenergialain mukaan luvanhaltijan on huolehdittava ydinvoimalaitoksen turvallisuudesta. STUK varmistuu valvonnallaan siitä, että luvanhaltija kantaa vastuunsa.
