Investigations concerning Olkiluoto 3

The investigation team provided recommendations both to the buyer and the vendor company

On 7 March, 2006, STUK appointed an investigation team when it was found that the operations of organizations participating in the construction of the Olkiluoto 3 nuclear power plant unit did not fully meet STUK's expectations of operations in accordance with a good safety culture. The identified problems have hindered the progress of the project and increased the schedule pressure on future phases. The investigation team states in its report that the biggest problems are related to project management, in particular with regard to construction work, not to nuclear safety.

The Radiation and Nuclear Safety Authority approved a plan for developing the management of safety requirements made by Teollisuuden Voima and the consortium responsible for constructing the new nuclear power plant. However, the Radiation and Nuclear Safety Authority still wants to ensure that the plan is implemented.
