Rosatom: Turbine generator for Unit 1 delivered to Akkuyu NPP site (Turkey)

Akkuyu NPP is the 1st Nuclear Power Plant in Turkey and the biggest project in the history of Russian-Turkish relations

Rosatom: Turbine generator for Unit 1 delivered to Akkuyu NPP site (Turkey)

Mersin Province, March 17 - Neftegaz.RU. The main components of Unit 1 turbine plant including stator, turbine generator rotor and low pressure (LP) cylinder, were delivered to the Eastern cargo terminal at the Akkuyu NPP construction site.

The total mass of the cargo batch exceeded 1 000 tons.
The heaviest piece of equipment delivered was the turbine generator stator, which weights over 430 tons and is 12 m long.

Cargo of that size falls under uniquely heavy category and requires special preparation for its unloading and subsequent transportation.
Weight of other delivered items is 260 tons for turbine generator rotor, 240 tons for lower casing and 147 tons for upper casing of the LP cylinder.

With the use of the crane, the turbine plant components were transferred to self-propelled modular transporters and transported to temporary storage areas at the Akkuyu NPP construction site.
Unloading operation of all the equipment components lasted 7 days.

Sergey Butckikh, Director of Akkuyu NPP under construction, said:
  • Turbine generator stator is the heaviest NPP equipment, so its transportation is subject to particularly strict requirements
  • In the near future we expect the arrival of another low pressure cylinder body and a noise-protective turbine enclosure
  • This year we are planning to start installation of the main process equipment of Unit 1 turbine building
The turbine generator consists of 2 main parts – a rotor and a stator.
The stator is a spacious cylindrical structure of steel 12 m long.

Inside the stator, which is the stationary part of the generator, the rotor, a powerful accumulator of mechanical energy, rotates.
This particular equipment is involved in the conversion of mechanical energy into electrical energy.

The structure of Akkuyu NPP steam turbine consists of 3 modules: one combined high and intermediate pressure cylinder (HP and IP cylinder) and 2 LP cylinders.
Each module is equipped with a cylinder with blades, into which steam is supplied.
While passing through the HP and IP cylinder the steam spins the turbine, which produces electricity.
