Unit 4 of the Fuqing nuclear power plant in China's Fujian province has been connected to the grid, China National Nuclear Corporation (CNNC) announced today. The 1087 MWe CPR-1000 unit becomes the country's 37th operational power reactor.

CNNC said the unit was connected to the grid at 6.09pm on 29 July.

First concrete was poured for unit 4 in December 2012 and its dome was put in place in June 2014. The process of loading the 157 fuel assemblies into the reactor core began on 13 June this year and was completed on 19 June. The unit achieved a sustained chain reaction for the first time on 16 July.

The unit will now undergo a load test run and other relevant testing before entering full-power demonstration operation. It is expected to enter commercial operation later this year.

CNNC's Fuqing plant will eventually house six Chinese-designed pressurised water reactors, the first four being 1087 MWe CPR-1000 units. Units 1 to 3 entered commercial operation in November 2014, October 2015 and October 2016, respectively.

China's State Council gave final approval for construction of Fuqing 5 and 6 in mid-April 2015. First concrete was poured for the fifth unit in May 2015, while that for unit 6 was poured in December. These will be demonstration indigenously-designed Hualong One reactors.

CNNC said it expects all six units at Fuqing "to be fully commissioned and put into operation in 2021".

The Fuqing nuclear power plant project is owned by CNNC subsidiary China Nuclear Power Company (51%); Huadian Fuxin Energy Company (39%); and Fujian Investment and Development Group (10%).
