Fortum increases the output of Loviisa NPP by 5 MW through turbine island modernization

​The eight Moisture separators and the reheaters (MSR) at Fortum's Loviisa nuclear power plant will be modernized during 2015-2017. The investment will increase the nominal output of Loviisa Power Plant by a total of about 5 MW.

The MSR equipment is a part of the plant's secondary circuit. It dries and reheats the steam from the high-pressure turbine, thus improving the utilization rate of the low-pressure turbine.

"The improvement of the turbine generator's utilization rate does not increase the reactor's thermal power heat. Since it concerns the secondary circuit only, it has no impact on the reactors or nuclear safety", says group manager Samuli Savolainen.

The replacement contract has been signed with German heat exchanger company Balcke-Dürr GmbH, and the work will be carried out during normal planned annual maintenance outages. The modernization is a part of the continuous improvement program of Loviisa Power Plant aimed to secure safe and economic energy production until the end of the plant's lifetime.

The total annual output of the Loviisa units is 992 MW at present. Last year, Fortum announced a modernization of the inner parts of its high-pressure turbines during 2014 - 2017. The two investments will increase the output of Loviisa NPP by a total of 29 MW - with the plant's average load factor, this increase would have covered almost the whole energy consumption of Loviisa and Pyhtää municipalities in 2011 (source: Finnish Energy Industries).
