The Haiyang 2 AP1000 in China has been synchronized as reported by world-nuclear-news.org.
In September 2007, Westinghouse and its partner the Shaw Group received authorisation to construct four AP1000 units in China: two at Sanmen in Zhejiang province and two more at Haiyang in Shandong province.
Sanmen 1 was the world’s first AP1000 to start up, achieving first criticality on 22 June and grid connection on 2 July. It reached full power operation for the first time on 14 August and completed a full-power demonstration test run on 21 September. Sanmen 2 attained first criticality on 17 August and was grid connected a week later. The unit is expected to enter commercial operation by the end of this year.
Unit 1 of the Haiyang plant attained first criticality on 8 August and was grid connected on 17 August. That unit is also scheduled to enter commercial operation by year-end.
On 11 October, China National Nuclear Corporation subsidiary Sanmen Nuclear Power Company signed provisional acceptance certificates with the suppliers of the Sanmen 1 unit: Westinghouse Electric, China National Nuclear Engineering, Harbin Electric, Mitsubishi and Zhejiang Thermal Power Corporation.

The signing of the certificates followed the unit completing a 700-hour demonstration run and performance test, as stipulated in the supply contract. The unit now starts a period of operation under guarantee from the suppliers, after which final acceptance certificates will be signed.
Four AP1000 reactors were also being built in the USA – two each at Vogtle and Summer. However, construction of the two Summer units was suspended in August 2017.
