The Nuclear Regulatory Commission (NRC) on June 23 accepted for formal review Centrus Energy Corp.’s application to produce high-assay low-enriched uranium (HALEU) at its Piketon, Ohio, facility. The move marks a third major regulatory milestone for advanced nuclear over the past month.

The NRC’s acceptance of Centrus’ application follows a 4-0 vote by the commission on May 26 to implement a more streamlined and predictable licensing pathway for advanced non-light water reactors. The NRC on June 16 also announced it had accepted for formal review a first-of-its-kind combined license application (COL) from Oklo Power to build and operate the company’s Aurora fast reactor at the Idaho National Laboratory (INL) site in Idaho.
