Bid to find suitable cooling tower for Rooppur NPP

Russian experts are examining the technical and economic aspects of two types of cooling towers before coming up with the best option for the Rooppur nuclear power plant (NPP).
Experts of Atomproekt, a sister concern of Russia's state nuclear corporation  Rosatom are examining technical and economic aspects of Natural Draft and Ventilation cooling towers, a company insider has said.
A cooling tower is an important part of NPP infrastructure. It is a hydro technical construction for cooling water in NPP water circulation systems.
Modern Natural Draft cooling towers are up to 180 metres high and are able to cool up to 170,000 cubic metres of water per hour.
Ventilation cooling towers are an alternative to Natural Draft wet cooling towers which are traditional for NPPs.
This type of cooling tower has not been used earlier in NPP turbine condenser cooling systems, as more cooling towers with Ventilation need to be installed.
However, given the conditions in Bangladesh, which has high temperature and humidity, the use of this type of cooling tower may be justified, the source has said.
Besides, Atomproekt designers and engineers are designing Ventilation cooling towers for the emergency raw cooling water system of the Rooppur NPP.
Use of these Ventilation cooling towers allows a considerable reduction in the area covered by cooling equipment and an increase in water cooling efficiency.
Such a project has been developed in Russia for the first time. Earlier, spray ponds were traditionally used in the emergency raw cooling water system.  
Atomproekt has designed more than 100 cooling towers for power plants in Russia and abroad.
At the moment, their designs were used in constructing cooling towers at Leningrad NPP-2 and in Astravets NPP in Belarus, said the source.
