Annual outage 2015 at Fortum’s Loviisa nuclear power plant completed


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 30 August
2015, and Unit 2 for approximately 16 days until 15 September. The planned
duration of Loviisa 1 outage was exceeded by 3 working days due to hydrogen
generator leak repairs and replacement of the turbine reheaters.

This year both Units underwent a so-called short outage during which one
quarter of the fuel in both units was be replaced.

At Loviisa 2, the most significant outage work, besides the normal scheduled
maintenance and fuel replacement, consisted of activity measurement of turbine
steam lines and the replacement of an emergency diesel generator to an
overhauled motor.

“During this summer’s annual outage we began the modernisation of the power
plant’s turbine reheaters which improve the reliability of the secondary
circuit as well as the efficiency of the power plant,” says Pertti Salonen,
Manager of Loviisa power plant’s Maintenance Unit.

We are getting good results on our long-term development work to lower the
radiation levels for the personnel during the annual outage at both power plant
units. During this years' annual outage, the radiation levels were the lowest
in the history of the power plant at Loviisa 1 and Loviisa 2 among the lowest.

"The annual outages as a whole were carried out safely, according to plan and
schedule and no major incidents endangering personnel or plant safety occured,"
explains Timo Eurasto, Manager of Operations Unit at Loviisa power plant.

A total of 750 external contractors are involved in the Loviisa power plant’s
annual outage and ongoing modernisation projects. About 90 per cent of the
workers are of Finnish origin. There are approximately 500 Fortum employees and
some 100 permanent contractors working at the Loviisa power plant.
