Tianwan Nuclear Power Station (Chinese: 田湾核电站/田灣核電站) 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 nuclear power plant consists 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.[1]

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.[1]
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.[2][3]
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 Tianwan nuclear power plant has two operating units and six planned future reactors:
