A Federal Nuclear Power Agency spokesman said Russia's state controlled nuclear power corporation will have a 51%-share in the JV.
He said the deal is designed to meet growing demand in the nuclear power plant market for power generation, both in Russia and abroad.
He said the JV will operate from the platform of the machine-building firm ZIO Podolsk in the Moscow Region.
ZIO Podolsk is the main supplier of equipment to the Bushehr nuclear power plant under construction in Iran.
The total level of investment in the JV is 300 million euros.
The future joint venture will manufacture the entire conventional island of nuclear power plants, drawing on Alstom's "Arabelle" half-speed turbine technology. Alstom will transfer technology to the joint-venture company, namely for the manufacture of its "Arabelle" steam turbine and generator.
Alstom said the agreement will allow the two partners to propose a complete package including the nuclear reactor and the conventional island.
The joint venture will benefit from the best available technology for the conventional island of its nuclear power plants and will have exclusive access to the fast-growing Russian nuclear power plant market.
Alstom is the world leader in nuclear conventional islands, with 175 islands either already in service or in the course of being built in twelve countries around the world, including France, South Africa, China, South Korea and Sweden. Alstom technology is present in more than a quarter of nuclear conventional islands around the globe.
