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.[4][5]

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.[6] 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.[6] The first pair of reactors were estimated to cost more than 40 billion yuan (US$5.88 billion).[7]

Excavation for the first unit was completed in September 2008. Quality of the pit was certified, putting the project 67 days ahead of schedule.[8] 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.[9][10] First concrete for Sanmen 2 was poured on December 15, 2009.[11]

In June 2014, China First Heavy Industries completed the first domestically produced AP1000 reactor pressure vessel for the second AP1000 unit.[12]

The units were originally projected to begin operation in 2014 and 2015. In April 2015, a start date of 2016 was projected for both.[13] One month later, the start date was put back to 2017.[14][15] In January 2017 China National Nuclear Corporation (CNNC) announced that the final reactor coolant pump had been installed with start of operations still foreseen for 2017.[16] As of March 2018, Sanmen 1 has completed pre-fuelling safety checks but is not expected to be connected to the grid until the fall of 2018 at the earliest.[17] Hot testing of Sanmen 1 was completed in June 2017, and fuel loading started on April 25, 2018. It subsequently became the first AP1000 reactor in the world to achieve first criticality at 2:09 AM on June 21, 2018,[18] and was connected to the grid on June 30, 2018.[19]
