The U.S. nuclear power regulator has approved production of uranium fuel that is far more enriched than fuel for conventional nuclear power plants, the company aiming to make the material said on Monday.

The fuel is known as high-assay, low-enriched uranium, or HALEU. Nonproliferation experts are concerned about the fuel as it is easier to convert into fissile material, the key component of nuclear weapons, than conventional reactor fuel.

Centrus Energy Corp said the Nuclear Regulatory Commission, or NRC, approved the company’s request to produce HALEU at a Piketon, Ohio, plant, and it expects to be demonstrating production of the fuel early in 2022.
