Specialists from the Izhora plant (part of Rosatom's Mechanical Engineering Division) in St. Petersburg have assembled the reactor vessel for power unit No. 1 of the El Dabaa NPP, which is being built in Egypt. This was reported by the corporation's press service.
Workers have completed welding the closing seam connecting the individual parts of the VVER-1200 reactor vessel. The work lasted 10 days with continuous heating of the weld zone.
Mechanical engineers used about 2 tons of flux and more than 1.5 tons of special wire during the work.
After welding, the vessel will undergo heat treatment. Then, specialists will check the quality of the weld using radiographic flaw detection, ultrasonic and capillary testing (allows to determine surface and through defects, including cracks, voids with an opening width of up to 0.1 μm).
