Site Status Summary

The Lead Cascade was a test loop of the American Centrifuge Plant (ACP) located in Piketon, OH. The Lead Cascade demonstrated the effectiveness of the centrifuge design and equipment by processing uranium in a closed loop. After the demonstration was completed, the facility made a financial decision to cease uranium enrichment operations in February 2016, followed by removal of uranium gas from the centrifuges and process piping, dismantling of process equipment, and other actions needed to ultimately decommission the facility.

In March 2016, American Centrifuge Operating, LLC (ACO) notified the NRC of Centrus Energy Corp's decision to cease operation at the Lead Cascade and to terminate the Lead Cascade's Materials license (SNM-7003). In May, ACO submitted a proposed amendment to the license to downgrade licensed activities at the Lead Cascade to "Limited Operations" and to remove the regulatory permission to enrich. After conducting a site visit to verify the company's claims, NRC issued an approval to the license amendment in December 2016.
