The Xudabao Nuclear Power Plant, also known as Xudapu, is a nuclear power station under construction in Xudabao Village, Haibin County, Xingcheng, Huludao, on the coast of Liaoning province, in northeast China. It was initially planned to have six 1000-MW AP1000 or CAP1000 light water reactors,{{cite web |date=30 July 2024 |title=Nuclear Power in China {{!}} Country Profiles |url=https://world-nuclear.org/information-library/country-profiles/countries-a-f/china-nuclear-power |website=Information Library |publisher=World Nuclear Association |access-date=5 August 2024}} but the first two to start construction were changed to VVER-1200s.{{cite web |date=2019-03-12 |title=General contract signed for Tianwan Phase IV |url=http://www.world-nuclear-news.org/Articles/General-contract-signed-for-Tianwan-Phase-IV |website=World Nuclear News |publisher=World Nuclear Association |access-date=2019-03-26}}

China National Nuclear Corporation (CNNC) owns 70% of the project, along with Datang International Power Generation Company (20%), and State Development and Investment Corporation (10%). China Nuclear Power Engineering Company (CNPEC) is the general contractor for the project; the initial version with six AP1000s was expected to cost around CN¥110 billion (US$16 billion) back in 2016.{{cite web |date=2016-10-14 |title=Contract for nuclear islands of Xudabao Phase I|url=https://www.world-nuclear-news.org/NN-Contract-for-nuclear-islands-of-Xudabao-Phase-I-1410164.html |website=World Nuclear News |publisher=World Nuclear Association |access-date=2022-02-28 |archive-url=https://web.archive.org/web/20161018052556/http://www.world-nuclear-news.org/NN-Contract-for-nuclear-islands-of-Xudabao-Phase-I-1410164.html |archive-date=2016-10-18 |url-status=dead}}

Preliminary work on the site began in 2010, but no nuclear concrete pour was made, and works were suspended for several years after the 2011 Fukushima Daiichi nuclear disaster. In 2014, the National Nuclear Safety Administration (NNSA) granted approval for the first two units. In 2016, China Nuclear Industry 22 Construction Company (CNI22), a subsidiary of China Nuclear Engineering and Construction Corporation (CNECC) signed an EPC contract for the first two units.

CNNC and Atomstroyexport signed the detailed contract for the construction of two VVER-1200s (Xudabao 3 and 4) on 7 March 2019.

First concrete pour started on 28 July 2021, with Unit 3, which despite its designation is the first reactor at the site. Work on Unit 4 began in May 2022.{{cite web |last=Rogers |first=David |date=6 August 2021 |title=China begins work on $17bn Xudabao nuclear power station |url=https://www.globalconstructionreview.com/china-begins-work-17bn-xudabao-nuclear-power-stati/ |website=Global Construction Review |publisher=Chartered Institute of Building |access-date=15 September 2021}} Rosatom will supply the nuclear island; the turbine generators will be supplied by China.{{cite magazine |date=5 August 2021 |title=Construction begins of Xudabao 3 |url=https://www.neimagazine.com/news/newsconstruction-begins-of-xudabao-3-8969101 |magazine=Nuclear Engineering International |publisher=Progressive Media International |access-date=15 September 2021}} Commercial operation of both units is expected by 2028.{{cite web |date=3 April 2019 |title=AtomStroyExport unveils schedule for China projects |url=http://www.world-nuclear-news.org/Articles/AtomStroyExport-unveils-schedule-for-China-project |website=World Nuclear News |publisher=World Nuclear Association |access-date=3 April 2019}}
