Sanmen Nuclear Power Plant in Zhejiang, and two at Haiyang Nuclear Power Plant in Shandong. The Sanmen 1 & 2 AP1000s were connected to the grid on July 2, 2018, and August 24, 2018, respectively. Haiyang 1 started commercial operation on October 22, 2018, and Haiyang 2 on January 9, 2019. In 2014, China First Heavy Industries manufactured the first domestically produced AP1000 reactor pressure vessel, for the second AP1000 unit of Sanmen Nuclear Power Station. The first four AP1000s to be built are to an earlier revision of the design without a strengthened containment structure to provide improved protection against an aircraft crash. China had officially adopted the AP1000 as a standard for inland nuclear projects. Following Westinghouse's bankruptcy in 2017, China decided in 2019 to build the domestically designed Hualong One rather than the AP1000 at Zhangzhou. After 2019, all plans for future AP1000 units were superseded by CAP1000 units, which are a local standardization of the AP1000 design, transitional to the CAP1400. It is said to have reduced cost and improved operation and maintenance attributes. As of 2021, site preparations have been done for Haiyang, Lufeng, Sanmen, and Xudabao for the construction of eight additional CAP1000 units. However, most of these projects are at a standstill, as construction of all CAP-1000 units has been slowed down significantly. At the Xudabao site, construction of two VVER-1200 units for Xudabao 3 & 4 was started in 2021 while the planned CAP1000 units for phase 1 & 2 are still on hold. On 20 April 2022, the construction of Haiyang 3 & 4 and Sanmen 3 & 4 was approved by the State Council. However, Lufeng 5, using a Hualong One unit, was decided to be built first instead of the CAP1000 units for Lufeng 1-4 which had already been approved by the National Development and Reform Commission. On 14 September 2022, the State Council approved construction of Lianjiang 1 & 2. Turkey In October 2015 it was announced that technology for the İğneada Nuclear Power Plant in Turkey will come from US based firm Westinghouse Electric Company in the form of two AP1000 and two CAP1400. United States Two reactors are being constructed at the Vogtle Electric Generating Plant in the state of Georgia (Units 3 & 4). In South Carolina, two units were being constructed at the Virgil C. Summer Nuclear Generating Station (Units 2 & 3). The
