A new nuclear power unit using Hualong One, a domestically designed third-generation nuclear reactor, began commercial operation on Monday in south China's Guangdong Province, according to China General Nuclear Power Corporation (CGN).

The commissioning of the No.2 unit marks the completion and full operation of the first-phase project of the Taipingling nuclear power plant – the first nuclear project in the Guangdong-Hong Kong-Macao Greater Bay Area to deploy Hualong One technology.
