Olkiluoto 3 reactor delayed again

The latest postponement is due to additional turbine inspections. The reactor is some 13 years behind its original schedule.

The long-delayed commissioning of Finland's fifth commercial nuclear reactor will be delayed once again.

According to plant supplier Areva-Siemens, the start-up date for Olkiluoto 3 (OL3) will be pushed back by a month. On Friday the company said it expects regular electricity production to begin in March 2022.

The third unit at the Olkiluoto site in Eurajoki, southwest Finland, has been under construction since 2005.

Plant officials are running the last major test set before starting the plant unit and starting electricity production. Based on the test results, they have decided to carry out additional maintenance and inspection measures on the turbine.

This means that initial electricity generation would start on a testing basis in November, with full commercial electricity generation to begin in March 2022.

Under the most recently announced schedule, commercial operations were to begin in February.

The reactor has been beset by repeated delays and cost overruns. OL3 was originally to have begun operations in 2009.

In May, Areva-Siemens and plant owner TVO finally resolved a long-running dispute over the completion of the project.
