The annual outage at Fortum's Loviisa nuclear power plant starts on Sunday 21
August. Loviisa unit 1 will undergo the outage first, followed by unit 2 right
thereafter. The work on unit 2 is estimated to be completed by the end of
In addition to normal maintenance and refuelling, the most significant
maintenance works on Loviisa 1 include modifications of sumps in the steam
generator room, replacements of 6 kilovolt (kV) switchgear circuit breakers as
well as opening of the steam generator primary collectors and change of seals.
On Loviisa 2, besides refuelling and normal maintenance tasks, one reserve
diesel will be replaced with a renovated one and 6 kV switchgear circuit
breakers will be replaced.
Altogether some 750 maintenance and inspection specialists from 76 companies
will join the power plant's 500 own employees in the annual outage.
Annual maintenance guarantees safe and undisturbed functioning of the power
plant. In 2011, the Loviisa power plant produced 7.7 terawatt-hours of
electricity, corresponding to the annual consumption of 385,000
electrically-heated detached houses. The capacity factor describing the plant's
availability was about 91 percent last year. The figure is one of the best
among nuclear plants in the world, despite the fact that Loviisa unit 2
underwent the longest possible annual outage type.
