Annual outage 2017 to begin at Fortum’s Loviisa nuclear power plant

FORTUM CORPORATION PRESS RELEASE 3 August 2017

The annual refuelling and maintenance outage of Fortum’s nuclear power plant’s
Unit 1 in Loviisa, Finland, begins on Sunday, 6 August, followed by the
servicing of Unit 2. This year both units will undergo a so-called short
refuelling outage. The entire outage procedure is estimated to be completed in
38 days.

In addition to the normal periodic maintenance tasks and refuelling, the most
significant work on both units this year is the renewal of the high-pressure
safety injection pump motors. At Loviisa Unit 1, also a modernised
high-pressure turbine will be installed and at Unit 2, two turbine moisture
separators will be replaced. During the outage, one quarter of the fuel will be
replaced.

"The modernisation works carried out in the annual outage ensure reliable
electricity production of the plant units to the end of their lifetime. With
the turbine modernisation, the unit's electricity output is estimated to
increase by about 6 MW and the automation renewal will improve the key safety
functions of the power plant. These investment projects are the biggest in
Loviisa power plant’s history and part of the continuous improvement and
lifetime management,” says Timo Eurasto, Manager of Loviisa power plant’s
Operations unit.

A total of 700 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.
