Olkiluoto 2 purrs again, but with less power than before

Olkiluoto 2 is again in operation and produces electricity for the national grid. The plant unit was put back into use on Sunday, October 6 at 5:26 a.m. The owner of the Olkiluoto nuclear power plant informs about the matter Power of Industry (TWO).

An increase in the humidity level was observed in the plant’s generator on Friday, September 9, when the unit’s electricity production was interrupted. The production stoppage lasted 28 days.

“The damaged water-cooled rotor of the generator has now been replaced, and electricity production was able to continue today. The power increase will take about 30 hours,” TVO says in the press release.

Olkiluoto 2’s electricity production continues at a lower power level of 725 megawatts. The maximum power of the plant unit would be 890 MW.

According to TVO, the power has been limited to reduce the risk of rotor failure. The company estimates that the power restrictions will last for several months.

The share of electricity used in Finland produced by Olkiluoto 2 is about eight percent.
