Billed to be the most powerful nuclear plant in Europe and third most powerful worldwide at 1,600 megawatts, Olkiluoto 3 reached full power in September.

The plant is expected to start permanent production on 8 March 2023 after conducting tests at various output levels.

This reactor has been under construction in Finland since 2005, marking the country’s first new nuclear plant in more than 40 years.

It is also the first such facility in Europe in nearly 15 years.

The plant, which will provide almost 14% of Finland’s electricity, reached first criticality a year ago.
