Cause of the Interruption in Olkiluoto 3's Electricity Production Identified
The electricity production of Olkiluoto 3 was interrupted yesterday, Sunday, November 19th, at 19:10 due to a fault detected in the turbine plant.
The Olkiluoto 3 unit was in normal production when a fault in the turbine plant automatically stopped the facility's electricity production. The facility operated as intended during the fault.
In the research, the cause of the fault was revealed to be a malfunctioning temperature measurement in the generator's cooling system. After the repair work, further inspections and testing will be conducted at the facility. According to the current estimate, the plant unit is expected to return to production at noon on November 21st.
The incident had no impact on nuclear safety.
