context_page_description: China is one of the world's largest producers of nuclear power. The country ranks third in the world both in total nuclear power capacity installed and electricity generated, accounting for around one tenth of global nuclear power generated.
  Nuclear power contributed 4.9% of the total Chinese electricity production in 2019, with 348.1 TWh. This is an increase of 18.1% from 2018; two new reactors came online in 2019.
  As of March 2019, China has 46 nuclear reactors in operation with a capacity of 42.8 GW and 11 under construction with a capacity of 10.8 GW. Additional reactors are planned for an additional 36 GW.
  Nuclear power has been looked into as an alternative to coal due to increasing concerns about air quality, climate change and fossil fuel shortages.
  In 2009, China's National Development and Reform Commission indicated the intention to raise the percentage of China's electricity produced by nuclear power to 6% by 2020.
  More long-term plans for future capacity are 120-150 GW by 2030.
context_section_description: The Westinghouse AP1000 is the main basis of China's move to Generation III technology, and involves a major technology transfer agreement. It is a 1250 MWe gross reactor with two coolant loops. The first four AP1000 reactors are being built at Sanmen and Haiyang, for CNNC and CPI respectively. At least eight more at four sites are firmly planned after them.
  In 2016 the build was reported to be running over three years late, mainly due to key component delays and project management issues. In February 2018 Sanmen 2 completed hot testing, and in April 2018 Sanmen 1 began fuel loading.
  In July 2018 the first reactor was connected to the grid with commercial operation expected by the end of the year.
  Following Westinghouse's bankruptcy in 2017, it was decided in 2019 to build the Hualong One rather than the AP1000 at Zhangzhou.
