Unit 5 at China National Nuclear Corporation’s (CNNC) Fuqing nuclear plant in southeastern China’s Fujian Province has become the world’s first Hualong One reactor to be connected to the power grid, the company announced on November 27. “It was confirmed on-site that all technical indicators of the unit met the design requirements and that the unit was in good condition,” CNNC said.

Fuel loading at Fuqing-5 began on September 4, following the issuance of the reactor’s operating license by China’s Ministry of Ecology and Environment. The loading of 177 sets of fuel assemblies was completed on September 10, and initial criticality was achieved on October 21. The unit is scheduled to enter commercial operation before the end of the year.

Also known as the HPR1000, the Hualong One is a Chinese-designed and -developed 1,000-MWe Generation III pressurized water reactor, incorporating design elements of CNNC’s ACP1000 and China General Nuclear’s ACPR1000+ reactors. Fuqing-5’s twin HPR1000, Fuqing-6, is scheduled to start contributing power to the grid next year.
