"In addition to normal periodical maintenance and refuelling at Loviisa 1, an engine of the emergency diesel generator was replaced with a renovated one, the 6-kV main switch at the switch plant was renovated as were the 400-kV switches at the switch field. All work was completed within the planned maintenance schedule," says Pertti Salonen, Manager of Loviisa Power Plant's Maintenance Unit.
At Loviisa 2, the most significant maintenance target, in addition to the normal periodic servicing and refuelling, was the 400-kV switches at the switch field. The renovation of the 400-kV switches on both units was carried out by Fingrid Oyj.
The maintenance was carried out according to plan, and no major incidents endangering personnel or plant safety occurred. Small technical problems during the start-up of Loviisa 1 delayed grid connection by two days. During the final testing of Loviisa 2, two control rods malfunctioned. Due to the malfunction, the control rods were tested several times and ultimately found to be functioning normally.
"The annual outages on both units went very smoothly. Despite extra checks and reports, the annual outages were successful also in terms of keeping on schedule," says Timo Eurasto, Manager of Loviisa Power Plant's Operation Unit. "Both units are in good shape now, and we expect an undisrupted refuelling interval as in previous years," Eurasto continues.
In addition to the 500 Loviisa employees, about 650 experts in the fields of maintenance and inspection from a total of 50 companies took part in the annual outages. 97 per cent of the contractor workforce was Finnish. The companies had direct contracts with Fortum.
