The CNP-600 is a generation II reactor based both on China's first commercial domestic nuclear reactor design, the CNP-300[1] and the M310 reactor design used in Daya Bay Nuclear Power Plant.
[2][3] The reactor has a capacity of 650 MW, a 2-loop design and 121 fuel assemblies.
Other features include single containment, 40-year design life and a 12-month fuel cycle.
There have been built two further CNP-600 reactors at Changjiang Nuclear Power Plant, which went into regular operation in 2015 and 2016.
A larger version of the design, the CNP-1000 with three loops, has been developed by the CNNC.
