Reactor internals are the major structures within the RPV. The primary function of the internals is to support the core, the control rod assemblies, the core support structure, and the reactor pressure vessel surveillance capsules.
Atomenergomash said the equipment weighs of 179 tonnes and includes an 11-metre core barrel, core baffle and a protective tube unit.
In November 2020, Russia delivered the RPV and one of four steam generators for Rooppur-1.
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.
