China’s state-owned nuclear power firm has unveiled the design for an advanced nuclear reactor that could mark a “crucial step” in the country’s plans to develop next-generation nuclear energy.

Named the CFR-1000, it will be China’s first commercial fourth-generation gigawatt-level fast neutron reactor. The facility is now awaiting approval and expected to become operational after 2030.

Other major nuclear powers, including Russia and the United States, are also working on advanced reactors with the aim of developing a more fuel-efficient source of power.

The China National Nuclear Corporation (CNNC) told a symposium on advanced nuclear energy held on Tuesday in Fuzhou that the preliminary design of the reactor – which has a maximum output capacity of up to 1.2 gigawatts of electricity – had been completed.

The event in the capital of southeastern Fujian province – where China has built a demonstration reactor – was attended by representatives from the China Atomic Energy Authority and National Energy Administration.

China’s two largest conventional reactors, Taishan Units 1 and 2 in southern Guangdong province, can generate 1.75GW of power.
