Russia’s Atommash, part of the engineering division of state nuclear corporation Rosatom, has completed hydraulic testing on the reactor pressure vessel for Unit 2 of the Rooppur nuclear power station under construction in Bangladesh, Russian nuclear equipment manufacturer Atomenergomash said.

The 330-tonne RPV was filled with distilled water and heated to 65 degrees Celsius. Tests were then carried out with a maximum pressure of 24.5 megapascals (MPa), which is about 1.4 times higher than operating pressure.

In a nuclear power plant, the RPV is the pressure vessel containing the nuclear reactor coolant, core shroud, and the reactor core.
