The Sanmen Nuclear Power Station (Chinese: 三门核电站) is a nuclear power station under construction in Sanmen County, Zhejiang Province in China. Groundbreaking for the first and second units was held February 26, 2008.[2][3]

Sanmen NPS will be the first implementation of the AP1000 pressurized water reactor (PWR) developed by Westinghouse Electric Company. The contract was agreed in July 2007.[4] Announcement of the project start came roughly twelve months after Westinghouse won a bidding contest over other companies. The contract for the new plant involved The Shaw Group (now Chicago Bridge and Iron), a minority shareholder in Westinghouse. Westinghouse is controlled by Japanese Toshiba. The Shaw Group will provide engineering, procurement, commissioning, information management and project management services.[4] The first pair of reactors will cost more than 40 billion yuan (US$5.88 billion).[5]

Excavation for the first unit was completed in September 2008. Quality of the pit was certified, putting the project 67 days ahead of schedule.[6] Construction of Sanmen Unit 1 began on April 19, 2009, as the first 5,200  of concrete were poured for the foundation, in a ceremony attended by State Nuclear Power Technology Corporation (SNPTC) chair Wang Binghua and Westinghouse CEO Aris Candris.[7][8] First concrete for Sanmen 2 was poured on December 15, 2009.[9]

In June 2014, China First Heavy Industries completed the first domestically produced AP1000 reactor pressure vessel for the second AP1000 unit.[10]

The units were originally projected to begin operation in 2014 and 2015. As of April 2015, a start date of 2016 is projected for both. [11] One month later, the start date was put back to 2017.[12][13]
