CPR-1000

CPR-1000 (Chinese PWR) is a Generation II reactor technology developed by China Guangdong Nuclear Power Group (CGNPG), now known as China General Nuclear Power Group (CGN). It is a three-loop design derived from the Areva M310 design, and the first unit was commissioned in 2010.

Design

The CPR-1000 is a Pressurized water reactor (PWR) design, with three coolant loops and a 157-fuel-assembly core. The design is based on the French M310 design, but with some features from the four-loop Framatome ANP P4 design. The CPR-1000 retains the analog control systems of the M310 design, rather than adopting the digital instrumentation of more modern designs.

Development

The development of the CPR-1000 began in the 1990s, as part of China's efforts to develop a domestic nuclear power industry. The first CPR-1000, Ling Ao-2, was connected to the grid in 2010. As of 2014, 14 CPR-1000 reactors were in operation, with another 20 under construction.

Future

The CPR-1000 design is being phased out in favor of the Hualong One, a Generation III reactor design. The Hualong One incorporates passive safety features and digital control systems, which are not present in the CPR-1000 design.
