Alstom Power Systems has secured a turbine generator set delivery contract for the Hanhikivi 1 nuclear power project, which is being constructed using Russian technology in Pyhäjoki, Northern Finland.

The delivery contract has been signed by Hanhikivi 1 unit’s plant supplier RAOS Project and French Alstom Power, a part of GE Steam Power Systems.

The contract includes the design and supply of turbine generator equipment package as well as advisory services for installation and commissioning works.

Fennovoima, the owner of Hanhikivi 1 plant, said that the design work of the set will start immediately and it will be based on Alstom Arabelle technology.

Given the delivery and installation schedule, the commissioning of the power plant is expected to start in, with commercial operations in 2024.

Fennovoima said: “The turbine generator contract is one of the biggest equipment supply contracts for the Hanhikivi 1 unit, and the contract is a significant milestone for the project.”

The turbine generator will be used to convert the steam generated in the reactor island into electricity to be distributed to the national grid.

The company said: “In practice, almost dry steam from the reactor unit is piped to the turbines. This heat energy makes the turbines rotate and the generator – which is on the same shaft as the turbines – converts the kinetic energy of the turbines into electricity.”

Under the contract, Alstom Power System will supply most parts of the equipment for turbine island during next 7 years.

Built by Fennovoima, a partnership between Voimaosakeyhtio and Rosatom, the Hanhikivi 1 nuclear power plant is a AES-2006 pressurized water reactor (PWR). The power plant will have a total capacity of 1,200MW.
