Regular power generation at OL3 nuke plant delays further

The regular electricity production of the nuclear power plant Olkiluoto 3 (OL3) will be delayed by one more month due to foreign material issues observed in the turbine’s steam reheater, said the company Teollisuuden Voima Oyj (TVO) in a press release on Wednesday.

According to information received from the plant supplier, OL3 EPR’s regular electricity production, which was earlier scheduled to be started in September, will now start in December.

Foreign material detached from the steam guide plates was found in the turbine’s steam reheater in May 2022, which requires inspection and repair work.

According to investigations from the plant supplier, the repair work will last until the end of July.

The plant unit’s test production programme and electricity production can only be continued after the completion of this repair work.

Furthermore, additional time has been reserved in the schedule for the plant unit’s upcoming tests and their analyses based on previous experiences from the test production phase.

The test production phase will be completed in December 2022, which is when the plant unit’s regular electricity production starts.
