CPR-1000

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.[citation needed]

Construction

Fifteen CPR-1000 units were under construction by June 2010.[1] On 15 July 2010, China’s first CPR-1000 nuclear power plant, Ling Ao-3, was connected to the grid,[2] having started criticality testing on 11 June 2010.[3] It started commercial operations on 27 September 2010,[4] with Ling Ao-4 starting commercial operation on 7 August 2011.[5]

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[6]), with net power output below 1,000 MWe, and using mostly imported components.[7]

Design

The CPR-1000 uses as its base design units 5 & 6 of the Gravelines Nuclear Power Station in France.[6]

Some CPR-1000 intellectual property rights are retained by Areva, which limits overseas sales potential.[1] 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.[8][9] In January 2012, CGNPG agreed a partnership with Areva and EDF to develop a reactor based on the CPR-1000,[10] which may create a design converged with Mitsubishi and Areva's 1000 MWe Atmea reactor.[11]

ACPR-1000 development

In 2010, CGNPG announced a further design evolution to a Generation III level, the ACPR-1000, which would also replace intellectual property right-limited components. CGNPG aimed to be able to independently market the ACPR-1000 for export by 2013.[12] CGNPG has been conducting the development work in cooperation with Dongfang Electric, Shanghai Electric, Harbin Electric, China First Heavy Industries and China Erzhong.[13]

Yangjiang 5 will be the first construction of an ACPR-1000 reactor, starting in late 2013.[14] This reactor will include a core catcher and double containment as additional safety measures.[15]

Following the Fukushima nuclear disaster, a revised design called at the time ACPR-1000+ was described. Features include double containment to protect against external explosions and airplanes, improved seismic capability to 0.3 g, increased core thermal margins and improved operation systems.[16] The gross power output has been increased to 1150 MWe.[17] The ACPR-1000+ is envisaged for export from 2014.[10]

Hualong One merged design

Since 2011 CGNPG has been progressively merging the ACPR-1000 with the China National Nuclear Corporation's ACP-1000 design into the new Hualong One design.[18]
