Name of the Project
Akkuyu nuclear power plant (NPP) project.

Location
Mersin, Türkiye.

Project Owner/s
Akkuyu Nuclear, comprising Inter RAO UES JSC, Rosenergoatom JSC, Atomtechenergo JSC, Atomenergoremont JSC and Rusatom Energy International JSC.

Project Description
The Akkuyu NPP will be based on an NPP-2006 serial project. The 4 800 MWe plant will comprise four VVER1200 reactors and is expected to meet about 10% of Türkiye’s electricity needs.

The power unit includes a reactor plant and a turbine plant.

The primary circuit is radioactive and comprises a reactor, four reactor coolant loops, four reactor coolant pumps, heating parts of four steam generators and one steam pressuriser.

The secondary circuit is not radioactive. It comprises steam generators; fresh steam conduits; one turbine unit comprising a turbine plant and a turbine generator; condensate pumps; a system of low-pressure regenerative heaters; a turbine condensate system; deaerators; a feedwater system, including feedwater pumps; and a system of high-pressure regenerative heaters.

The turbine is equipped with a condensing unit and regenerative installation for heating the feedwater and separators, with unregulated steam extraction for the NPP’s auxiliary needs and heating chemically treated water additives in the circuit.

Capital Expenditure
The project is estimated at $20-billion.

Planned Start/End Date
The aim is for the first unit of the plant to start supplying Türkiye's energy system in 2025, and for all four units to be operational by the end of 2028.

Latest Developments
The main bridge component of the polar crane, weighing 282 t, was installed in the reactor compartment of Unit 2 on March 25, 2026. The structure was lifted into place at a height of 38.5 m using a self-propelled heavy-duty crawler crane. The fifth tier of the inner containment at Unit 2 was recently concreted, with 240 m³ of self-sealing concrete poured continuously over about six hours. Once the structure had gained sufficient strength, the crane bridge steelwork was installed.

The polar crane is a key reactor-compartment system and will be used throughout the unit’s operating life for equipment handling, reactor maintenance and other technological operations. 

Installation of the crane structures, followed by the installation of safety-system tanks using the open-top method, will prepare the Unit 2 reactor building for installation of the inner containment dome.

Mounted beneath the inner containment dome, the circular overhead crane operates on a circular rail above the reactor shaft, allowing for handling operations across the reactor building. It is designed for moving large equipment, supporting reactor maintenance and reloading fuel. The full crane assembly, including the bridge, main and auxiliary trolleys, lifting and travel mechanisms, as well as pivoting device, will weigh about 500 t.
