MINSK, 14 August (BelTA) – The Russian company ZiO-Podolsk (part of Atomenergomash, which is the mechanical engineering division of the Russian state corporation Rosatom) has finished making and sent on their way the SPP-1200 separator superheaters and components for the second power-generating unit of the Belarusian nuclear power plant, BelTA has learned.
The manufactured products weigh a total of 422 tonnes. The separator superheaters are designed to dry and reheat the steam released after the high-pressure cylinder of the turbine. The separator superheaters are vertical devices made of three parts in the same shell. In the machine hall they will be assembled in a vertical position, towering as high as 22 meters. The intermediate steam reheating system is part of the auxiliary systems, which keep the turbine plant running. The equipment is designed to last for 50 years.
The engineering design and construction documentation were developed in-house by ZiO-Podolsk. Specialists of the company also oversee the manufacturing and installation of the equipment.
ZiO-Podolsk has already made and shipped four sets of SPP-1200 separator superheaters for the first unit of the Belarusian nuclear power plant and two sets for the second unit. Such devices have also been made for new power-generating units of the Novovoronezh nuclear power plant and the second Leningrad nuclear power plant.
Atomenergomash enterprises make virtually all the critical equipment for the Belarusian nuclear power plant with its VVER-1200 type reactors. The choice includes reactors and core catchers, piping, steam generators, main circulating pumps, pumps for cooling systems, and other things.
The Belarusian nuclear power plant will have two power-generating units of the Russian VVER-1200 design with the total output capacity of up to 2,400MW. The standard Russian nuclear power plant design AES-2006 has been chosen for building Belarus' first nuclear power plant. It is a 3+ generation design that boasts improved performance parameters and is compliant with post-Fukushima safety norms as well as requirements stipulated by environmental protection laws, sanitary and hygienic regulations.
