Energy development company ONE Nuclear has launched technical, geological, and environmental site investigations in Louisiana for Project Amberjack, a proposed multi-unit nuclear power complex designed to generate up to one gigawatt of electricity.
ONE Nuclear secured control of the project site following initial planning phases. The company had previously completed a site suitability analysis, an evaluation of location constraints, and a conceptual layout for the facility.
The next phase of field work will evaluate soil structures, surrounding environmental conditions, and the availability of cooling water. Engineers will also review site logistics, power transmission capacity, and options for connecting the multi-unit facility to the regional electrical grid.

ONE Nuclear has not selected a specific reactor technology for Project Amberjack. The company is carrying out a technology selection process without commitment to a single reactor type, comparing available designs for small modular reactors before making a final determination.
Small modular reactors, often called SMRs, are advanced nuclear reactors designed with smaller physical footprints than traditional power plants. Their modular nature allows key components to be prefabricated in factories and shipped to location for assembly. A one-gigawatt power output is equal to one billion watts, enough energy to supply electricity to hundreds of thousands of residential homes.
Regulatory Filings and Site Assessment
Project Amberjack remains in its early planning stages. ONE Nuclear has not yet selected a final plant configuration or received authorization from the U.S. Nuclear Regulatory Commission, the independent federal agency that regulates commercial nuclear energy and materials in the United States.
The company emphasized that initiating site studies does not imply approval of a reactor construction license, final engineering decisions, or compliance with environmental permits. Instead, the testing is designed to assemble the technical and environmental data necessary to support future regulatory filings.
If constructed to its full intended scale, Project Amberjack would supply up to one gigawatt of nuclear power using multiple reactor units. The current phase requires ONE Nuclear to demonstrate that the chosen site, future technology, grid connection, and environmental conditions can support a licensable nuclear complex.
