Full power production at the Olkiluoto 3 nuclear power plant has been pushed back yet again, with production now scheduled for September 2022, instead of July.
The delay is to allow for extra inspection work to be carried out on the plant's cooling systems, the facility's operator Teollisuuden Voima (TVO) said in a statement on Thursday.
Pre-operational testing and electricity production at the southwest Finland plant will continue after those inspections.
TVO said the repair needs are not related to the plant's boron pumps turning on unexpectedly last week.
Olkiluoto 3's full power electricity production was originally due to start in 2009, but the project has been beset by a series of setbacks, including faulty components, safety tests, and even a lawsuit.
The 1.6-gigawatt OL3 will become Finland’s fifth and biggest reactor, and is expected to produce around 14 percent of Finland’s electricity once it is fully operational.
