Electricity production at Olkiluoto 3 (OL3) nuclear power plant resumed after a glitch on Monday, the owner of the plant Teollisuuden Voima Oyj (TVO) said on Tuesday.

The power generation at OL3 disrupted on Monday at about 11:40 due to a turbine malfunction.

In the investigations initiated after the situation found a failure in the differential pressure measurement of the generator's sealing oil and hydrogen coolant.

Earlier on May 16, the Olkiluoto 3 (OL3) nuclear power plant returned to electricity production after 74-day outage.
