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, regenerative installation for heating the feed water and separators – steam superheaters – 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
The commissioning of the first power unit is expected in 2021, with subsequent units to be commissioned every year thereafter.
Latest Developments
The Volgodonsk branch of Russia's AEM Technology has completed the manufacture of the reactor cover for Unit 1 of the Akkuyu NPP. The product weighs 93 t and has a diameter of 4.5 m.
The manufacture of the reactor lid is a lengthy process and takes up to one-and-a-half years. The work includes hydraulic tests to confirm the strength and density of the base metal and welded joints of the reactor head. To confirm the alignment of the elements, the reactor lid undergoes a control assembly as part of the upper block. The main stages of manufacturing took place under the supervision of the Turkish Nuclear Regulatory Agency.
The reactor head, like the reactor pressure vessel (RPV), belongs to the items of equipment of the first category of seismic resistance, AEM Technology has said. The service life of the reactor head is 60 years, with the possibility of extending this by another 20 years, it notes.
The RPV for Akkuyu Unit 1 was delivered to the site in Mersin province on November 10.
Key Contracts, Suppliers and Contracts
