Ø Tianwan Nuclear Power Station Site
Tianwan Nuclear Power Station Site contains a twin 1060 MW VVER (Russian PWR) nuclear power station. China National Nuclear Corporation is the majority shareholder of the nuclear power station. The station was jointly built by CNNC and Atomstroyexport (ASE) from Russia.
The site is located at Lianyungang Municipality in northern Jiangsu, on the shore of the Yellow Sea and named after a local fishing village. It has a capacity to take 2 additional generating units, and may accommodate another 4 similar units.
Tianwan Nuclear Power Station is classified as Type AES-91 (sometimes also known as VVER 1000/428), adopting the Russia VVER 1000/V320 technology. It has the following salient features:
- Reactor thermal output at 3300 MW and gross electrical output at 1060 MW
- A design life of 40 years
- A designed capacity of 80%
- Uranium with 4.1% fuel enrichment for an 18 month fuel cycle
- Light water as moderator and primary coolant
- Digital station control system
- Double-wall pre-stressed cylindrical concrete containment building
- Core catcher beneath the reactor vessel to accommodate a molten reactor core in a hypothetical core melt accident
- Probability for severe radiological release less than 1 in 107 reactor year.
The station began construction in 1999, with the two units reaching commercial operation in May and August 2007. The investment cost was reported at USD 3.2 billion.
Ø Other Nuclear Power Stations under development in 2010
China Guangdong Nuclear Power Company (CGNPC) entered into an agreement with China Power Investment (CPI) to construct a twin CPR 1000 PWR nuclear power station in Hongyanhe, Liaoning Province. Construction began in 2007 for full commercial operation in 2012. The two partners began the construction of another twin CPR 1000 PWR nuclear power station in 2009 at the same site for full commercial operation in 2014.
CGNPC entered into an agreement with Datang to construct a twin CPR 1000 PWR nuclear power station in Ningde, Fujian Province. Construction began in 2007 for full commercial operation in 2012. The two partners began the construction of another twin CPR 1000 PWR nuclear power station in 2010 at the same site for full commercial operation in 2015.
CGNPC began construction at Yangjiang in 2008 for four CPR 1000 PWR units for commercial operation in 2013 – 2016. Two CPR 1000 units are expected to follow at the same site. CGNPC entered into an agreement of cooperation intent with the CLP group in Hong Kong and the Guangdong Yuedian Group in Guangdong in 2010 for these two partners to each take a 17% share in Yangjiang.
China National Nuclear Corporation (CNNC) began construction of a twin CPR 1000 PWR nuclear power station in Fuqing, Fujian Province. Construction began in 2008 for full commercial operation in 2014. Four more units are expected to follow at the site.
CNNC also cooperates with the China Huaneng Group to construct a twin CNP 600 nuclear power station at Changjiang, Hainan Province. Construction began in 2010 for full commercial operation by 2015.
State Nuclear Power Technology Corporation (SNPTC) entered into an arrangement with Westinghouse in December 2006 to supply four AP 1000 PWR (at nominally 1250 MW each) to Sanmen, Zhejiang Province and Haiyang, Shandong Province and to provide technology transfer. These two project sites are primarily owned by CNNC and CPI respectively. Construction began at Sanmen in 2009 for full commercial operation in 2014, and at Haiyang in 2010 for full commercial operation in 2015.
In November 2007, CGNPC entered into an agreement with Areva in France to supply two European Pressurized Water Reactor (EPR) at Taishan (at nominally 1700 MW each) and to provide technology transfer. Construction began in 2009 for full commercial operation in 2014. Electricite de France has a 30% share in the project.
Work is also in progress to develop nuclear power stations for inland provinces, and to introduce more advanced reactor designs for power generation. A 210 MW high temperature gas cooled reactor plant is planned at Shidaowan, Shandong Province and two 800 MW fast neutron reactors of Russian design are planned near Sanming, Fujian Province.
