The outage for Olkiluoto 3 has started
10.9.2026
The outage began a few hours ahead of schedule on the evening of September 9, when the plant unit was automatically disconnected from electricity production due to a fault detected in a steam generator.
At the time of the event, the unit was already operating at a very low power level as part of the planned shutdown process. The plant functioned as designed, and the event had no impact on nuclear safety.
