Manufacturing of Reactor Coolant Pumps (RCP) Unit-1 of Rooppur Nuclear Power Project runs at fast pace at Petrozavodsk Branch of AEM-Technology in Russia. Reactor coolant pump is a very important safety item for a nuclear power plant.
Welding of joints in all reactor coolant pump casings has been completed, discharge and suction branch pipes are being welded to the spherical casings. RCP bends after hot forming at Volgodonsk Branch have been delivered to the factory and will be welded to the casings after incoming inspection.
RCP at a nuclear plant ensures coolant circulation from the reactor to steam generators and operates under pressure of 160 atmospheres and temperature of 300 degrees celsius. Weight of one casing is more than 31 tons with height of 3.5 m and width more than 3 m.
The Rooppur NPP with two Generation 3+ Russian VVER-1200 reactors will have a total capacity 2400 MW. VVER 1200 reactors fully meet all international safety requirements. AEM-Technology is part of Atomenergomash, the machine-building division of the State Corporation Rosatom. Atomenergomash is the single-source manufacturer for the Rooppur NPP reactor hall and a supplier major portion of the turbine island equipment.
