ASE JSC [Atomstroyexport Joint Stock Company, part of Rosatom] vice-president for Projects in China and Prospective Projects Alexey Bannik said: “Installing the reactor vessel requires fair accuracy.  Russian specialists provided technical support to Chinese partners in this technological process.

“After the installation of all large-sized equipment has been completed, the engineering division will supervise the installation and adjustment of the equipment at Unit No 8.”

ASE JSC focuses on the design, construction and modernisation of nuclear power plants both within Russia and internationally.

In April 2024, Rosatom began the commissioning phase for the first unit at the Akkuyu NPP in Turkey.

Akkuyu is Turkey’s first nuclear power plant and will feature four water-water energetic reactors designed by Russia.

Construction began in 2018, and the first shipment of nuclear fuel arrived at the site in April 2023.

Rosatom considers the Turkey project important as part of its influence on the global development of nuclear power.

Following the completion of the Akkuyu NPP, Turkey plans two additional plants at Sinop and Thrace.
