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

Location
Mersin, Turkey.

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 Turkey'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 for heating chemically treated water additives in the circuit.

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

Planned Start/End Date
Construction of the first unit began in 2018, with startup planned for 2023. Construction of Unit 2 started in April 2020.

Latest Developments
The first safety-related concrete has been poured for Unit 4 of the Akkuyu NPP, which follows a wide range of preparatory work that included dewatering, excavation of a basement pit, installation of a concrete cushion and waterproofing, reinforcement of the basement and installation of embedded parts.
