Tianwan Nuclear Power Plant
Encyclopedia
Tianwan Nuclear Power
Station 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.
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.
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.
Nuclear power
Nuclear power is the use of sustained nuclear fission to generate heat and electricity. Nuclear power plants provide about 6% of the world's energy and 13–14% of the world's electricity, with the U.S., France, and Japan together accounting for about 50% of nuclear generated electricity...
