Tianwan Nuclear Power Plant is a large nuclear power station in Lianyungang prefecture level city, Jiangsu province, People's Republic of China. It is considered to be the largest nuclear plant on mainland China. It is located on the coast of the Yellow Sea approximately 30 kilometers east of Lianyungang proper.

The Tianwan Nuclear Power Plant of two reactor units each rated at 1,000 MW capacity and constructed by Russia's Atomstroyexport. The first reactor began full operations in 2006 and the second in 2007.

Construction commenced on 20 October 1999 for the first unit, and on 20 October 2000 for the second reactor unit. The first reactor went critical on 20 December 2005. Construction of the second reactor finished in May 2007 and commercial operation began in August.

On 23 November 2010, Jiangsu Nuclear Power Corporation signed a contract with Atomstroyexport according to which Atomstroyexport will supply 1060 MWe VVER-1000 reactors for units 3 and 4.

Both units use VVER pressurized water reactor (PWR) technology supplied from Russia. Together they cost approximately US$3.3 billion. The units are the Russian standard reactor type VVER-1000/392 (also carries the designation of VVER-1000/428) adapted specifically for China. This reactor version was equipped with Siemens control systems and received additional protection from earthquakes.

The Qinshan Nuclear Power Plant is a multi-unit nuclear plant under construction in Qinshan Town, Haiyan County, Zhejiang, the People's Republic of China. When completed, it may hold the record for the most nuclear reactors on one site; however, since the majority of the units are mid-size, it may be surpassed by other plants in terms of generating capacity. The construction of the units is divided into separate stages.

Stage I involved construction of the small-scale (~300 MW) Unit-1 only, but was the first domestically designed and constructed nuclear power plant in the nation (95 percent of components came from domestic manufactures). That unit has so far operated for more than 10 years without an event rating 2 on the International Nuclear Event Scale.

Stage II the next set of reactors were mid-scale plants (~600 MW) but still of Chinese design. The steam generators were made by the Shanghai Boiler Factory in conjunction with Westinghouse.

Stage III involves construction of CANDU-6 series of the CANDU reactor design supplied by Atomic Energy of Canada Limited. This was reported to be the largest business venture between Canada and China to that time. In 2001, it was visited by the Canadian Prime Minister Jean Chrétien.
