Loviisa gets new cooling towers

In the heart of Finland, the Loviisa witnessed the completion of the new air cooling systems. Although, the backup system is already present in the cooling of the sea water in Loviisa. However, they evolved the technology and built a modern and state of the art air cooling system for the enhancement of the plant. The new system will ensure the safety of the water as well and can be utilized and put to work in certain extreme situations when the plant’s reactors will not be cooled down by the sea water alone.

The heat exchangers are the new addition and the towers are situated in three separate buildings. According to the reports, the buildings do not have any significant impact and value on the plant area landscape. The height of the buildings is approximately 15 meters and they are 10 meters wide. There are two units of the Loviisa and a tower has been built for every unit. The purpose of the first tower is to eliminate the decay and clean the reactor while the second tower will also remove the heat from the fuel storage pools that have already been used and the tower will also be cooling the other equipments.

The towers are supplied by an engineering company in Hungary and are designed by Fortum. The towers get their power supply from plant reserve systems. The towers have been completed in terms of construction and the installation of machinery but they are yet to be made operational. The final testing of these towers is due later this year.

The towers use the sea water, which is approximately 40 cubic meters per second, for the cooling of the steam which regulates the electricity generating turbines. And the same water that was cooled down goes back to the sea after getting about 10 degrees centigrade warmer, with the rest of its properties still intact.

The nuclear reactors in the heat exchangers also need cooling when they are not functional. This will eliminate the heat that is being generated by the decaying of the radioactivity. Because of this reason, the emergency cooling system is enabled in all the nuclear plants to ensure the cooling systems are working properly even when the primary system fails to do so. In case of the loss and scarcity of the sea water, the Loviisa plant has a very well maintained back-up system. Moreover the construction of the new towers will further ensure the plant’s safety in the future as well.

There are many air cooling systems which are working remarkably, but the new cooling towers in Loviisa are one of the best and also the first of its kind in the world, and a great nuclear power plant. These towers are also the finest and very cost effective when it comes to the safety and the cooling of sea water. The towers will be operational after its testing by the concerned authorities later in 2015.
