Annual outages at Fortum's Loviisa nuclear power plant completed

23 SEPTEMBER 2014 AT 11.00 EEST

Both units at Fortum's Loviisa nuclear power plant are back in production after
their annual maintenance outages. Unit 1 was down for 21 days until 16 August
2014, and Unit 2 for approximately 35 days until 20 September.

Loviisa Unit 1 underwent a so-called short outage that included no extensive
alterations or reparations. Unit two had a wider four-year maintenance. During
the outages, about one fourth of the fuel in both reactors was replaced.

In addition to the normal scheduled maintenance and fuel replacement on Loviisa
1, the low-pressure casings of turbine 1 were preserviced and modernised, a
rotor was exchanged to generator 1, one generator transformer and generator
switch were replaced and evaporator inspections were carried out.

"The co-operation of the various participants to the annual outages has
improved further, which is clear evidence of how committed our employees are to
high-quality operations," says Pertti Salonen, manager of Loviisa power plant's
maintenance unit.

At Loviisa 2, the most significant outage work, besides the normal scheduled
maintenance and fuel replacement, consisted of modernisation of the primary
coolant circuit pressure control, renewal of the relief valves of the main
steam lines, replacement of one main transformer and generator switch, renewal
of the circulating water piping, turbine maintenance, generator rotor
replacement, extensive inspections of the evaporators as well as containment
leak testing.

The most important safety improvement for the 2014 annual outages was a
significant reduction of the radiation levels of the reactor loop, thanks to
persistent material study and development. The reduced radiation levels,
combined with improved working methods, is evidenced in smaller radiation
dosages for the personnel than in comparable outages before.

"The annual outages as a whole went safely, according to plan and schedule and
without major incidents endangering the safety of personnel or the plant," says
Timo Eurasto, manager of the operation unit of Loviisa power plant.

A total of 930 contractors were involved in the annual outage and the Loviisa
power plant’s ongoing modernisation projects. There are approximately 500
Fortum employees and some 100 permanent contractors working at the Loviisa
power plant.

Background information for journalists:
In 2013, the load factor at Fortum’s fully-owned Loviisa nuclear power plant
was 92.5%. On an international scale, this was excellent: the worldwide load
factor for pressurised water power plants last year was approximately 83%. The
plant produced a total of 8.04 terawatt hours, which is approximately 9% of
Finland’s total electricity production. With the electricity produced in
Loviisa, 6 million tonnes of CO2 emissions are avoided annually. In 2013,
Fortum invested EUR 60 million into the Loviisa nuclear power plant.

Fortum’s purpose is to create energy that improves life for present and future
