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 closure of the thermal control layer of the Akkuyu NPP has allowed for the installation of the turbine-generator set to proceed.

Turbine building roof installation has been completed at Unit 2, which took about three months.

The turbine building roof comprises nine prefabricated truss blocks, each

weighing between 95 t and 175 t, and 61 m long. The roof was assembled concurrently with the closure of the thermal control layer on two specially built benches using a Liebherr LR 13000 heavy crawler crane for installation.

Rosatom reports that the installation of the roof trusses in the turbine building required careful preparation and a high level of organisation and construction planning, as every truss was installed with an accuracy of 10 mm.
