Radiation and Nuclear Safety Authority (STUK) will begin the safety assessment of the operating licence application of the third nuclear power plant unit at Olkiluoto. The assessment will take approximately one and a half years. Teollisuuden Voima submitted its application for operating licence to the Finnish Council of State today, 14 April 2016.

“TVO has already submitted most of the operating licence materials to STUK. STUK has granted a six-month extension only for the provision of certain analysis results”, says Tapani Virolainen, Deputy Director of STUK’s Nuclear Reactor Regulation Department.

STUK will assess whether the requirements for the safe use of the plant are fulfilled. As STUK has already inspected and approved the design of the plant during the construction phase, the focus in the operating licence phase is on the verification of updated safety analyses and the organisation’s preparation for operation.

“TVO has prepared safety analyses of various accident cases. STUK verifies whether these analyses are correct by acquiring independent comparison analyses,” Virolainen explains.

In the assessment of the organisation, especially important topics include the adequacy and competence of personnel and, on the other hand, the instructions needed for the operation and plans concerning for example security and emergency response arrangements as well as nuclear material regulation. The Finnish Council of State may only grant the operating permit for the plant if STUK determines that the safety requirements are met.

Decisions on applications for nuclear power plants are prepared by the Ministry of Employment and the Economy. STUK will deliver its statement to the Ministry at the end of 2017 according to the preliminary schedule.

In parallel with the safety assessment, STUK also carries out supervision of trial use of the plant on the Olkiluoto 3 construction site. The purpose of the trial use is to demonstrate that the plant described in the application for operating licence is operating as planned. Olkiluoto 3 currently requires approximately 25 man-years of STUK resources annually.
