Indications of damaged fuel have been detected at Finnish power company Teollisuuden Voima's (TVO's) Olkiluoto 1 (OL1) nuclear power plant unit in Eurajoki, Finland. The power level of the plant unit will be reduced to 65% on 7 July 2022 so that the damaged fuel can be localised. The increase of the power level will start later on the same day and full power is expected to be reached on 8 July 2022.
The plant unit will be brought to a shutdown and disconnected from the national grid on 10 July 2022 for the removal of the damaged fuel elements. Electricity generation at the plant unit is expected to continue on 16 July 2022.
