Atomstroyexport said transportation of the equipment to the construction site took about 10 weeks, with a distance covered of more than 14,000 km along land, sea and river routes.
The RPV and steam generators are among the largest reactor components, weighing about 330 and 340 tonnes respectively. They were manufactured at an Atommash production site near Volgodonsk in southwest Russia.
There are two Russia-supplied 1,200-MW V-392M pressurised water reactor units under construction at the Rooppur site, about 150 km from the capital Dhaka.
First concrete for Rooppur-1 was poured in November 2017 and for Rooppur-2 in July 2018. A general contract was signed between Russia and Bangladesh in 2015.
