**SUPPLEMENTARY INFORMATION:**
**I. Discussion**
The NRC staff conducted an operational readiness and management measures verification review and prepared inspection reports documenting its findings in accordance with the requirements of the NRC's Inspection Manual. The reports are available for review and are listed in Section II of this notice. The publication of this notice satisfies the requirements of paragraph 70.32(k) of title 10 of the *Code of Federal Regulations* (10 CFR), and section 193(c) of the Atomic Energy Act of 1954, as amended.
License Condition 11 of the ACP license authorized the HALEU demonstration program on June 11, 2021, but prohibited the introduction of UF <sub>6</sub> into the HALEU demonstration cascade modules until the NRC completed an operational readiness and management measures verification review. The NRC staff's review verified that the licensee was in compliance with the performance requirements of 10 CFR 70.61, and that the systems, structures, and components designed to support safe operation of the HALEU Demonstration Cascade were constructed in accordance with license requirements. By letter dated June 12, 2023, the NRC authorized the American Centrifuge Operating, LLC (ACO) to introduce UF <sub>6</sub> into the HALEU demonstration cascade module to produce Category III quantities of special nuclear material (SNM) at the ACP. By letter dated September 21, 2023, the NRC authorized ACO to commence enrichment operations in the HALEU demonstration cascade module to produce Category II quantities of SNM up to the quantity approved on June 11, 2021 at the ACP.
