China National Nuclear Corporation (CNNC) has poured first concrete for the containment building basemat of the sixth unit at the Tianwan nuclear power plant in the Jiangsu province of China.
The Tianwan nuclear power plant is operated by the Jiangsu Nuclear Power Corporation, a joint venture between China National Nuclear Corporation (50%), China Power Investment Corporation (30%) and Jiangsu Guoxin Group (20%). It consists of two 990 MW (1,060 MW gross) pressurised-water reactors (PWRs) commissioned in 2006 and 2007 and of two similar units that are currently under construction on the site. Tianwan 3 and 4 will be AES-91 VVER-1000 units designed by Gidropress and supplied by Russian state firm Rosatom. Construction started in December 2012 for the third unit (expected in 2016) and in September 2014 for the fourth unit. The containment dome was installed at unit-4 in September 2015 and the reactor is expected in 2017.
Construction of units 5 and 6 was initially expected to start in early 2011 but was deferred in the wake of the Fukushima accident. The new units, both 1080 MWe ACPR1000 reactors, received the approval of the State Council in December 2015. Construction has already started on unit 5 and the reactor is expected to be commissioned in December 2020. Unit 6 should be commissioned in October 2021.
