Fortum’s annual outage 2017 at Loviisa nuclear power plant completed
FORTUM CORPORATION PRESS RELEASE 22 September 2017
Both units at Fortum’s Loviisa nuclear power plant are back in production after
their annual maintenance outages. The annual outage of Unit 1 lasted
approximately 22 days, until 27 August, 2017. All scheduled work at Unit 1 was
completed on time. However, the total duration of the annual outage was
exceeded by approximately two days due to malfunction of a valve during
start-up. The maintenance outage of Unit 2 lasted approximately 17 days, until
21 September. All scheduled work was completed one day ahead of schedule.
Start-up of unit 2 was prolonged 12 hours due to trip of feedwater pumps during
This year both units underwent a refueling outage. In conjunction with the
annual outages, about one quarter of the fuel in both units was replaced.
In addition to the normal periodic maintenance tasks and refueling, 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 was installed and at Unit 2, two turbine moisture
separators were replaced.
“This year several challenging projects were successfully implemented at both
units, thanks to high quality planning. Overall, the work went smoothly,” says
Anssi Laakso, Manager, Plant Lifetime Management and Maintenance unit.
Good results have been achieved in the long-term development efforts to lower
the radiation levels at the plant during the annual outage. Thanks to the
continuous development work, the collective radiation doses for personnel
during annual outage at Unit 1 were the lowest in the plant’s history and among
the lowest for Unit 2 compared to similar types of outages.
“At the power plant, tidiness and good order are prerequisites for an efficient
and safe working environment. In our daily operation we pay attention to them,
and especially during annual outage when the number of employees and work to be
done is multiplied in comparison with normal operation. A great step forward
was taken in managing the premises and work sites. This is one of the
contributing factors why no injury related loss of workdays occurred during
this annual outage,” Laakso continues.
A total of some 700 external employees participated in the Loviisa power
plant’s annual outage that started in August and in ongoing modernisation
projects. About 80 per cent of the workers were Finnish subcontractors. There
are approximately 500 Fortum employees and some 100 permanent contractors
working at the Loviisa power plant year round.
