Russian firm evaluates Rooppur nuke plant's cooling options
Russian state nuclear corporation Rosatom's sister concern Atomproekt has begun examining the technical and economic aspects of Natural Draft and Ventilation Cooling Towers to select an optimum option for the Rooppur nuclear power plant (NPP).
A cooling tower is an important part of any NPP infrastructure; it is a hydro technical construction to cool the water in NPP water circulation systems.
The modern natural draft cooling towers are up to 180 metres high and are able to cool up to 170,000 cubic metres of water an hour, a statement said yesterday.
Ventilation cooling towers are an alternative to the natural draft cooling towers, which are traditional for NPPs. This type of cooling towers have not been used earlier in NPP turbine condenser cooling systems, as more cooling towers with ventilation need to be installed, and costs can go up with the additional energy for fan motors.
However, given conditions in Bangladesh with high temperatures and humidity, the use of this type of cooling towers may be justified.
Besides, Atomproekt designers and engineers are designing ventilation cooling towers for the emergency raw cooling water system at Rooppur plant.
The use of these ventilation cooling towers allows a considerable reduction in the area covered by cooling equipment and an increase in water cooling efficiency, the statement said.
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.
Russian state company Rosatom began working at Rooppur in mid 2013 and is currently undertaking a techno-feasibility study under a half-a billion dollar loan.
Atomenergoproekt, which is conducting the study, has recently floated a tender for an engineering survey, environmental monitoring and development of project documents for the Rooppur site.
