A watertight chamber, or caisson, was used for the hydraulic tests, during which a maximum pressure of 24.5 MPa was generated in the RPV 1.4 times higher than the operating pressure. A crane with a lifting capacity of 600 tonnes was used to lower the 11-meter RPV into the caisson. The tests confirmed the strength of the base metal and welded joints of the RPV.

Two 1200 MWe (gross) VVER-1200 units are being built at Rooppur, which is on the eastern bank of the river Ganges at Rooppur, 160 km from Dhaka.
