The manufacturing of the required Reactor Coolant Pumps (RCP) is progressing well at the Petrozavodsk branch of AEM-Technology in Russia for the first unit of the Rooppur Nuclear Power Project.
A reactor coolant pump is a very important safety item for a nuclear power plant, said a press release.
The welding of all reactor coolant pump casings has been completed. Discharge and suction branch pipes are being welded to the spherical casings. Some of the required parts will be welded to the casings after an incoming inspection.
RCP at a nuclear plant ensures coolant circulation from the reactor to steam generators, and operates under a pressure of 160 atmospheres and a temperature of 300 degrees Celsius. Each casing weighs more than 31 tons, and has a height of 3.5 m and width of more than 3 m.
The Rooppur NPP with 2nd Generation 3+ Russian VVER-1200 reactors will have a total capacity 2400 MW.
AEM-Technology is a 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 the supplier of the major portion of the turbine island equipment.
