This development came after the El-Dabaa NPP had previously seen the installation of the first tier of Inner Containment for the reactor building of Unit 1, a process that spanned from March to May.

ASE JSC vice-president and El-Dabaa NPP Construction Project director Alexey Kononenko said: “Today we are moving on to a new stage of the construction works of Unit 2 of the El-Dabaa Nuclear Power Plant in Egypt. Undoubtedly, our international team has done a tremendous job for this purpose.

“Whereas, the installation of Inner Containment of the reactor building is a technical operation that will result in the safe operation of the EL-Dabaa Nuclear Power Plant in the future.

“It is a great pleasure to acknowledge the close cooperation between both the Russian and Egyptian parties – currently, we are building all four units of the NPP simultaneously, ensuring overall development of the construction site of the Nuclear Power Plant.”
