Workers have finished concreting the containment building dome for Unit 2 of the of the Rooppur nuclear power station under construction in Bangladesh, Russian state nuclear corporation Rosatom said.

The company said the operation took 122 days to complete, five days ahead of schedule.

At a nuclear power reactor, the containment acts as a hermetic protection system, designed to withstand high external and internal pressures and protect against radiation release.

In September 2023, the 129-tonne outer steel containment dome was installed at Rooppur-2.

In June 2023, Russia said it had completed concreting of the inner containment dome of Rooppur-2, a necessary step before the installation of the outer containment superstructure.

The VVER-1200 PWR system has a two-part containment by design – one to protect from external physical influence and a second to secure the hermetic tightness around the core reactor equipment.

Russia is building two VVER-1200 pressurised water reactor units at the Rooppur site, about 150 km from the capital Dhaka, under a general contract signed in 2015. Atomstroyexport, 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.

The first fuel batch was delivered to Rooppur-1 in October 2023, signalling the unit is approaching the start of the commissioning phase.
