Both units of Fortum's Loviisa nuclear power plant are back in production after successful annual outages. On Loviisa 1, the outage ended on 7 September after 17 working days. Loviisa 2's annual outage began thereafter, and lasted over 19 days. It was completed on 30 September.
Both units underwent a so-called short refuelling outage. During the outage, approximately one third of the fuel was exchanged to both units and some inspections and maintenance work was carried out.
The most important maintenance targets, among others, were the safety improvements in the filter structures of the steam generator room of Loviisa 1, and the replacement of one Loviisa 2's reserve generators with a serviced one.
In addition to the 500 employees of the plant, about 640 maintenance and inspection professionals from a total of 76 companies participated in the annual outage. 74 of these companies were domestic.Quality work during the annual maintenance guarantees safe and undisturbed operation of the power plant. In 2010, Loviisa nuclear 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 in 2010.
