US ONE Nuclear Plans Up to 1 GW Small Modular Reactor Project in Louisiana

ONE Nuclear Energy LLC (ONE Nuclear) announced the launch of its Louisiana project portfolio, with a planned total installed capacity of 5 GW, covering dispatchable generation, grid-scale battery energy storage, data center infrastructure, and advanced nuclear development pathways. The portfolio includes the Cayman Project, the Amberjack Project, and the Barracuda Project. Among them, the one directly related to nuclear power is the Amberjack Project, which aims to build a multi-unit small modular reactor station fleet with an installed capacity of up to 1 GW.

ONE Nuclear CEO Richard·Taylor stated that the Louisiana project portfolio is designed to meet the growing US electricity demand in different but complementary ways. Among them, the Amberjack Project will establish a prudent pathway for advanced nuclear development.

According to current plans, the Amberjack Project will be advanced as an independent, scalable advanced small modular reactor project. Its final installed capacity, reactor technology pathway, and plant configuration remain subject to determination through technology selection, detailed engineering design, environmental assessment, transmission studies, commercial arrangements, financing, and federal licensing procedures.

ONE Nuclear stated that after securing site control, the Amberjack Project is conducting further technical and environmental assessments. Follow-up work includes land, geotechnical, and environmental site studies, cooling water and logistics condition assessments, transmission and grid interconnection analyses, vendor-neutral small modular reactor technology screening, and continued engagement with local, state, and community stakeholders and the US Nuclear Regulatory Commission (NRC).

The company also emphasized that the work completed to date does not constitute NRC site approval, reactor licenses, environmental authorizations, or final engineering decisions. The nuclear capacity targets in the Louisiana project portfolio remain at the planning level and are ultimately subject to conditions including engineering design, grid interconnection agreements, utility commitments, licenses, customer contracts, financing commitments, and construction decisions.

ONE Nuclear plans to hold a public information meeting in October 2026, inviting residents, local officials, landowners, community organizations, and other stakeholders to attend, to present the planning and study processes for the Cayman, Amberjack, and Barracuda projects, explain environmental, infrastructure, and licensing-related work, and gather community feedback before major development decisions.
