Rosatom Mechanical Engineers Assembled Reactor Vessel for Unit 1 of El Dabaa NPP (Egypt)

Rosatom, PUBLISHED 24.03.2025

The finishing welding to connect the parts of the VVER-1200 vessel for unit 1 of the El Dabaa NPP has been finished at the Izhora Plant in St. Petersburg (the NPP is being constructed by Rosatom's Engineering division in Egypt).

The welding to connect the vessel's parts took 10 days, with the weld area being continuously heated throughout the process. Mechanical engineers used approximately 2 tons of flux and more than 1.5 tons of specialized wire to complete the job.

After the welding, the reactor vessel will undergo a heat treatment to be followed by a thorough weld quality control including X-ray flaw detection, ultrasonic and penetrant inspections. These measures are crucial to ensure safe operation of the NPP for at least six decades.
