The annual outage of Fortum’s Loviisa nuclear power plant will begin with Unit 2 on Sunday, August 22nd, followed by the servicing of Unit 1. This year both units will undergo the short annual outage. The annual outages are estimated to last a total of about 38 days. 

This year the plant protection systems of both units will be renewed, and the automation modernisation of the emergency generators that was started in the previous annual outage will be continued. The modernisation project will replace the original automation systems with digital systems. During the annual outage, one quarter of the fuel will be replaced.

”The Loviisa plant units have been upgraded and modernised systematically and according to plans throughout its history. In this year’s short annual outage, we will do the normal periodic maintenance work and refuelling, as well as a number of measures that will improve plant and employee safety and operational reliability,” says Loviisa power plant’s Deputy Director  Thomas Buddas.

In addition to the power plant’s 530 employees, nearly 750 external workers will participate in the annual outage. Some 90 per cent of the workers are Finns. Additionally, there will be workers from France, Russia, Poland, Sweden, and the Baltic countries.
