About 20 joint projects are underway, with more in a pre-bid negotiation phase. Tianwan NPP is based on Russia’s improved AES-91 design and is acknowledged by most experts as the world’s safest nuclear power plant in operation. At present, the station operates two 1,000 MW reactor units launched in 2007. Units 3 and 4 of the same capacity are under construction, with the commissioning scheduled for 2018. Russia negotiates a possibility of constructing Units 7 and 8.
