FORTUM CORPORATION PRESS RELEASE 21 April 2015
The construction of Fortum’s Loviisa nuclear power plant’s new cooling system, i.e. the cooling towers that are independent of seawater cooling, has been completed. The new air cooling system enhances safety at the Loviisa power plant in the improbable extreme situation when seawater wouldn’t be available to cool the plant’s reactors.
The use of seawater for cooling could be prevented by, e.g., a wide-spread oil spill in the Gulf of Finland, or by exceptional natural phenomena, such as excessive, wind-borne algae colonies. The power plant has already had back-up systems in place for the seawater cooling. The new air-cooled system further supplements the back-up systems.
The new air-cooled heat exchangers, the cooling towers, are located in three buildings that have no impact on the landscape. The buildings are 10 meters wide and 15 meters high. Two cooling towers have been built for each plant unit. One tower is used for removing decay heat from the reactor, the other for removing decay heat from the spent fuel pools as well as for cooling off other equipment critical for safety. The towers used for removing decay heat from the reactors are located in the same building.
“Air-cooled systems have been used before in other types of power plants, but the kind of cooling towers used at Loviisa are the first in the world at a nuclear power plant. The solution is a cost-efficient way to further enhance the safety of the seawater-cooled nuclear power plant,” says Group Manager Samuli Savolainen from Fortum.
The cooling towers were designed by Fortum and supplied by the Hungarian GEA EGI Contracting/Engineering Co. Ltd. The towers were completed for their intended use in February 2015, and the final capacity and warranty testing will be conducted during the annual outage in summer.

Loviisa nuclear power plant
The load factor of Fortum’s fully-owned Loviisa power plant was 90.9% in 2014. On an international scale, the load factor was good: globally, the load factor for pressurised water power plants was about 84% last year. The power plant produced a total of 7.88 terawatt-hours of electricity, which accounts for about 12 per cent of Finland’s electricity production. The Loviisa power plant directly employs about 600 people. In 2014, Fortum invested a total of about EUR 80 million in the Loviisa power plant. Further information: www.fortum.com/loviisa
