The CPR-1000, or CPR1000, (improved Chinese PWR) is a Generation II+ pressurized water reactor, based on the French 900 MWe three cooling loop design imported in the 1990s, improved to have a net power output of 1,000 MWe (1080 MWe gross) and a 60-year design life.
The CPR-1000 is built and operated by the China General Nuclear Power Group (CGNPG), formerly known as China Guangdong Nuclear Power. Progressively more Chinese manufactured components were used in the units; the second unit built had 70% of its equipment manufactured in China, with a 90% Chinese content target for later builds.
Fifteen CPR-1000 units were under construction by June 2010. On 15 July 2010, China’s first CPR-1000 nuclear power plant, Ling Ao-3, was connected to the grid, having started criticality testing on 11 June 2010. It started commercial operations on 27 September 2010, with Ling Ao-4 starting commercial operation on 7 August 2011.
Four interim reactors at Daya Bay and Ling Ao Phase 1 are sometimes called CPR-1000s, but these are closely based on the French 900 MWe design (M310), with net power output below 1,000 MWe, and using mostly imported components.
The CPR-1000 uses as its base design units 5 & 6 of the Gravelines Nuclear Power Station in France.
Some CPR-1000 intellectual property rights are retained by Areva, which limits overseas sales potential. However the Financial Times reported in 2010 that Areva was considering marketing the CPR-1000 as a smaller and simpler second-generation reactor design alongside its larger EPR, for countries that are new to nuclear power. In January 2012, CGNPG agreed a partnership with Areva and EDF to develop a reactor based on the CPR-1000, which may create a design converged with Mitsubishi and Areva's 1000 MWe Atmea reactor.
