The annual outage of Fortum’s Loviisa nuclear power plant will begin with Unit 2 on Sunday, 7 August, followed by the servicing of Unit 1. This year, Unit 2 will undergo an extensive annual outage done every 4 years and Unit 1 the short annual outage. The annual outages are estimated to last a total of about 53 days.

During the annual outage, one quarter of the fuel will be replaced. In addition to the fuel replacement, both units will undergo various preliminary maintenance work, inspections, repairs and tests.  Additionally, the automation modernisation of Loviisa Unit 1’s emergency generators, which was started in the previous annual outage, will be continued. The modernisation project will replace the original automation systems with digital systems.

“The Loviisa plant units have been upgraded and modernised systematically and according to plans throughout the plant’s history. This year, too, in additional to the normal annual outage maintenance work, we will carry out a number of measures that will improve plant and employee safety and operational reliability,” says Sasu Valkamo, Vice President of Fortum’s Loviisa nuclear power plant.”

“We are also preparing for the power plant’s continued operations. Fortum has applied for a new operating licence for both Loviisa power plant units until the end of 2050. During the new operating licence period, the power plant is expected to generate a total of 170 terawatt-hours of emission-free electricity. Continuing production at Loviisa is particularly an investment in securing the supply of clean domestic electricity,” Valkamo continues.

In addition to the power plant’s 530 employees, some 750 external workers will participate in the annual outage.
