Annual outage 2016 to begin at Fortum’s Loviisa nuclear power plant

The annual refuelling and maintenance outage of Fortum’s nuclear power plant’s

Unit 1 in Loviisa, Finland, begins on Sunday, 7 August, followed by the

servicing of Unit 2. This year Unit 1 will undergo the extensive inspection

outage performed every four years and Unit 2 is scheduled for a so-called short

refuelling outage. The entire outage procedure is estimated to be completed in

eight weeks.



In addition to the normal periodic maintenance tasks and refuelling, the most

significant work on both units this year is the modernisation of high-pressure

turbines and replacement of main transformer and generator breaker. At Loviisa

Unit 1, reheaters and safety valves in the intial steam line will be replaced.

At Unit 2, the generator’s rotor will be replaced and major overhaul of stator

conducted. During the outage, one quarter of the fuel will be replaced.



"The turbine modernisation is among the most significant investment projects in

the Loviisa power plant’s history and part of the continuous improvement of the

plant. The investment ensures reliable electricity production of the plant

units to the end of their lifetime. The modernisation will significantly

improve the efficiency of the turbine plant’s electricity production without

increasing the reactor’s thermal output,” says Timo Eurasto, Manager of Loviisa

power plant’s Operations unit. Because the modernisation will target only the

turbines, it does not impact the reactor plant or nuclear safety.



A total of 950 external contractors are involved in the Loviisa power plant’s

annual outage and ongoing modernisation projects. There are approximately 500

Fortum employees and some 100 permanent contractors working at the Loviisa

power plant.

Loviisa power plant

In 2015, the load factor at Fortum’s fully-owned Loviisa nuclear power plant

was 92.9%. On an international scale, the load factor was among the best in the

world for pressurised water reactor power plants. The plant produced a total of

8.47 terawatt hours, which is approximately 13% of Finland’s total electricity

production. The Loviisa power plant employs approximately 500 Fortum employees

and 100 permanent contractors. In 2015, Fortum invested EUR 80 million into the

Loviisa nuclear power plant.
