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

turbine start-up.



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.
