The Volgodonsk Branch of JSC "AEM-technology" "Atommash" (a part of Rosatom's engineering division - "Atomenergomash"), performed successfully hydraulic tests of the first Steam Generator for the first Unit of the "Rooppur" NPP. This is one of the main stages of technical control.

All holes of the Steam Generator were previously closed with special blind covers. Then the primary and secondary circuits were filled with distilled water. The circuits of the Steam Generator are checked in turn. In the zone of the primary circuit, specialists supply a pressure of 24.5 MPa (243 atmospheres), while the water temperature is 350 degrees Celsius. The secondary circuit receives a pressure of 11.45 MPa (115 atmospheres), while the water is heated to 300 degrees. Both figures are 1.4 times higher than the operating pressure.

During hydraulic tests, the first Steam Generator for the "Rooppur" NPP confirmed the strength and tightness of the base metal and welds of the Steam Generator elements with supports.

The Steam Generator is a heat exchanger, is part of the reactor plant equipment and refers to the items of the first safety class. The length of the apparatus is about 14 meters, the diameter is more than 4 m, and the weight is 350 tons. The equipment of one NPP power unit includes four Steam Generators.

The "Rooppur" NPP is designed and built according to a Russian project. The power plant will consist of two power units with a capacity of 1200 MW each with VVER reactors of generation 3+.
