The power company said the unit ran through 168 hours of demonstration by June 5, meeting the requirements to enter commercial operation.
Yangjiang No. 2 uses a CPR-1000 pressurized water reactor. CGN began building unit No. 1 December 2008 and No. 2 the year after. Unit No. 1 went into operation in March last year.
CGN is building two more units at Yangjiang, both using Advanced CPR-1000. Construction of these began in 2013, and all six units are slated for operation in 2019.
With this unit operating, CGN now has a dozen nuclear reactors generating, with a power generation capacity of 12.7 GW.
