An additional five days for the annual outage of Olkiluoto 3

The first outage of Olkiluoto 3 will be extended by five days and will end on April 20. The fuel checks of the plant unit require more time than planned.

Previously, we reported on the cooling of the components slower than expected and some technical problems that caused a one-week extension to the annual maintenance. Now the five-day additional time is needed especially for extra fuel checks. When the fuel is transferred back to the reactor at the end of the annual outage, we want to ensure their cleanliness so that no loose parts get into the process.
 

The annual outage of OL3 started on March 2 and the work has otherwise progressed well. Approximately 1,100 external professionals are involved in the outage. Olkiluoto 1 and Olkiluoto 2 are normally producing electricity with a total capacity of about 1,780 MW.
 

Teollisuuden Voima Oyj has produced electricity for its shareholders, Finnish industrial and energy companies, safely and reliably for over 40 years. The island of Olkiluoto produces about 30 percent of Finland's electricity needs. 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.
