The CPR-1000 pressurized water reactor (PWR) was connected to the grid at 5.15pm on 25 October, China General Nuclear (CGN) announced.

The company said a series of tests would now be conducted at Fangchenggang 1, including a load test run, after which the reactor will enter commercial operation once it has successfully completed a test run lasting 168 hours.

Construction of the first two units at the Fangchenggang plant began in July 2010. The reactor pressure vessel of unit 1 was put in place in August 2013, while that for unit 2 followed in September 2014. The loading of 157 fuel assemblies into the core of unit 1 was completed on 6 September and it achieved first criticality on 13 October. Units 1 and 2 are scheduled to begin operation this year and next year, respectively.

A total of six reactors are planned to operate there. Units 1 and 2 are both CPR-1000s, units 3 and 4 are planned to be based on Hualong One reactors, and units 5 and 6 are to be AP1000s. All of these are models of large PWRs.

The Fangchenggang plant is 39% owned by Guangxi Investment Group and 61% owned by CGN.

China National Nuclear Corporation has already started construction of unit 5 of its Fuqing nuclear power plant in Fujian province based on its version of the Hualong One design. CGN said its plans to start construction of Fangchenggang units 3 and 4 - for which its own version of the reactor design has already been approved - later this year.

Fangchenggang 3 and 4 will be the reference plant for the proposed Bradwell B plant in the UK. CGN agreed last week to form a joint venture company with EDF Energy to seek regulatory approval for a UK version of the Hualong One design. CGN is expected to take a 66.5% share and EDF 33.5%. The two companies agreed to bring development of the Bradwell B project to the stage of a final investment decision.
