The world's first production line for high-temperature gas-cooled reactor (HTGR) fuel elements has started mass production at China North Nuclear Fuel, headquartered in Baotou in Northern China's Inner Mongolia autonomous region.

The 200,000 spherical fuel elements were made Monday, marking a transition from a test production line to an industrial one, according to Wang Shoujun, president of China National Nuclear Corporation, parent company of China North Nuclear Fuel.

China is cementing its leading position as a manufacturer of HTGR fuel elements, Wang said.

With a designed capacity of 300,000 spherical fuel elements per year, the production line will provide fuel for the demonstration high-temperature gas-cooled reactor plant being built at Shidaowan, near Rongcheng city in Shandong province.

China has independent intellectual property rights for the production line, which was put into operation in 2016. The HTGR is best known for its inherent safety design.
