Final testing and commissioning works are underway at Türkiye's Akkuyu Nuclear Power Plant, a senior executive said Monday, as the country moves closer to bringing its first nuclear reactor unit into operation.

Sergei Butckikh, general manager of Akkuyu Nuclear JSC, said work is progressing simultaneously across all four reactor units at the site in the southern Mersin province.

The plant, built by Russia's state nuclear energy company Rosatom under a 2010 accord ⁠worth nearly $20 billion, will consist of four reactors with a combined installed capacity of 4,800 megawatts (MW), with each reactor capable of generating 1,200 MW.

The first reactor is expected to come online in the coming months.

"We are currently at a very important stage in Unit 1," Butckikh told Anadolu Agency (AA). "All equipment and systems are undergoing the necessary inspection operations and are being prepared for the commissioning phase."
