All four steam generators have been installed at the design position at power unit No. 1 of the Rooppur NPP being constructed in the People’s Republic of Bangladesh (by Rosatom Engineering Division ASE JSC which is the general contractor for the NPP construction).
The Energospecmontazh JSC subcontracting organization’s specialists have carried out assembly operations to install the steam generators at their regular position in the power unit reactor compartment in accordance with the approved schedule.
“Another important stage of the installation works has been completed at power unit No. 1. “The steam generators being installed in the permanent position allows starting welding works on the main circulation pipeline to connect the primary circuit equipment, such as: a reactor, steam generators, main circulation pumps”, said Aleksey Deriy, ASE JSC Vice- President – Director of the Rooppur NPP Construction Project.
The steam generators were manufactured for the Rooppur NPP at the Atommash plant located in Volgodonsk (being the branch of AEM-Technologies JSC). The weight of each complete steam generator is 350 tons, its length is about 14 m and the diameter is more than 4 m.
The steam generators are the main equipment of the reactor plant circulation circuit and are designed to transfer the heat produced in the reactor core to the secondary circuit, where the steam to rotate the power unit turbine is consequently generated.
The Rooppur NPP site is located on the eastern bank of the Ganges River in Pabna district at a distance of about 160 km northwest of the city of Dhaka, the capital of the Republic of Bangladesh. The facility is designed and constructed by ROSATOM State Corporation Engineering Division. The nuclear power plant will consist of two VVER-1200 reactor power units, the life cycle is expected to be 60 years with a possible extension of the service life for another 20 years. The Russian design with VVER-1200 reactors implemented successfully at Novovoronezh NPP- 2 is selected for the first NPP in Bangladesh. This is an evolutionary Generation III+ design which fully complies with all international safety requirements.
