In a pressurised water reactor, the steam generators act as heat exchangers where water carrying heat generated from the nuclear reaction is used to turn demineralised water into steam.
Installation of the 350-tonne components, among the largest at a nuclear plant, will allow welding work on the main circulation pipeline to connect the primary circuit equipment, including the reactor pressure vessel and main circulation pumps, said Aleksey Deriy, director of the Rooppur project for Russia’s Atomostroyexport.
Russia is building two VVER-1,200 pressurised water reactor units at the Rooppur site, about 150 km from the capital Dhaka, under a general contract signed in 2015. Atomostroyexport, a Rosatom subsidiary, is the general contractor for the project.
First concrete for Rooppur-1 was poured in November 2017 and for Rooppur-2 in July 2018. Russia delivered the RPV and steam generators for Rooppur-1 at the end of last year. The components were manufactured by Atommash at their Volgodonsk factory.
