The San'ao Nuclear Power Plant (Chinese: Chinese: 三奥核电站) is a nuclear reactor under construction in the Zhejiang province of eastern China. It is planned to house 6 reactors, at least two of which will be pressurised water reactors.[2]
The plant is expected to produce 52.5 terawatt-hours of energy per year and will supply the larger Yangtze River Delta region.
Construction of the plant was authorized in May 2015 by the Chinese government.[3] The plant is being constructed by the Cangnan Nuclear Power Company, under the aegis of the state-owned China General Nuclear Power Group (CGN).[4] Construction of the first unit began on 31 December 2020[5] and construction of the second unit on 30 December 2021. The first unit is expected to begin operation in 2026, and the second unit in 2027.
In August 2024, CGN received approval to construct units 3 and 4.[6]
The San'ao Nuclear Power Plant consists of 6 planned reactors.
