Commissioning of Finland’s Olkiluoto 3 nuclear reactor delayed until May 2019


Operations at the Olkiluoto 3 (OL3) nuclear power plant facility in Finland have been postponed until May 2019.

Originally planned to commence by the end of next year, the new timeframe for the European pressurised reactor (EPR) unit was announced after the plant supplier Areva-Siemens consortium carried out a schedule rebaseline review.

Areva has also asked for more time to adjust the production plan, reported Bloomberg.

As per the revised plan, first connection to the grid is expected to take place in December next year.

Operated by Teollisuuden Voima (TVO), the unit is also planned to produce between 2TWh and 4TWh of electricity during the period between first connection and the beginning of regular production.

"There is still substantial work to be accomplished in the OL3 EPR project and it is essential that all the necessary technical, human, and financial resources are allocated to the project."

According to an Areva spokesman, the updated timeline for the OL3 EPR reactor has been announced due to adjustments based on information from a similar reactor being constructed in China. In addition, a more careful evaluation was also performed to determine the unit’s ability to reach full production.

The TVO OL3 project's senior vice-president Jouni Silvennoinen said: “We are very disappointed by this additional delay.

“There is still substantial work to be accomplished in the OL3 EPR project and it is essential that all the necessary technical, human, and financial resources are allocated to the project.”

The OL3 plant supplier consortium is currently engaged in the construction of the plant unit under a fixed-price turnkey contract.

Equipped with EPR technology, the OL3 unit is expected to produce 1,600MW of electricity and will be able to power around three million households.

Construction of the unit began in 2005, with a plan to start electricity production by 2009.
