Electricity generation at Olkiluoto 2 will be suspended for about two days

Power generation at the Olkiluoto 2 plant unit (OL2) will be suspended on Friday, 27 January pending the repair of a valve malfunction.

The power downgrade will begin at 5 p.m. on Friday and the plant will be disconnected from the grid at around 7 p.m. 
 
OL2´s electricity generation will resume on Sunday, 29 January. The plant unit will be paced back online on Sunday afternoon, after which a power increase will begin. Increasing the power takes about 50 hours.  
  
The issue has no impact on nuclear safety.

Teollisuuden Voima Oyj has produced electricity for its shareholders, Finnish industrial and energy companies, safely and reliably for over 40 years. Nuclear electricity generated at TVO's Olkiluoto plant covers approximately 30 percent of Finland’s electricity demand once Olkiluoto 3’s regular electricity production has started. Climate-friendly nuclear electricity not only benefits society but also reduces the environmental impact of energy production. Moreover, the world's first final disposal facility for spent nuclear fuel is under construction in Olkiluoto.
