The Nuclear Company proposes 6.6-GW Kentucky AP1000 campus

The Nuclear Company has proposed a nuclear campus in Lewis County, Kentucky, that could eventually host six Westinghouse AP1000 reactors with about 6.6 gigawatts of combined capacity. Called Prosperity One, the project would add a new nuclear site to a state with no operating commercial reactors, but it remains a development proposal, not an approved construction project; the company is targeting a 2028 construction start.

Key facts

• Prosperity One could host up to six AP1000 units, totaling approximately 6,600 megawatts.
• The developer says the initial phase would start with two reactors, contingent on site diligence, feasibility and permitting.
• The Nuclear Company has a 2028 target for construction to begin, after site development and federal approvals.
• The U.S. Nuclear Regulatory Commission renewed AP1000 design certification through 2066; that action does not authorize a specific project.

What happened

The Nuclear Company announced Prosperity One on October 21, describing a proposed energy campus on land in Lewis County along the Ohio River. The company says it has site control in the area and will work with landowner Sam Howard and local leaders. Its stated plan is a phased buildout, beginning with two AP1000 reactors and potentially expanding to six. The six-unit figure is the campus's maximum proposed capacity, not a construction commitment or a forecast of units that will necessarily be built.

The company says initial work will include geotechnical investigations, environmental assessments, site characterization and transmission interconnection planning. It also intends to prepare for nuclear licensing and begin site development activities. The company has not disclosed a project cost, financing package, power purchaser, finalized site layout or an NRC application for Prosperity One in its announcement. Those details matter: at this stage the proposal is a framework for development, with several technical and commercial tests still to clear.

Local participation is part of the announcement. Howard, a Lewis County landowner and founder of Trace Creek Construction, is partnering with the developer. County leaders have been pursuing a nuclear-ready community designation under the Kentucky Nuclear Energy Development Authority, according to the company. That designation and local support would not substitute for federal safety and environmental review.

Why it matters

If built at the stated full capacity, Prosperity One would be a large multi-unit project and a major test of whether a repeatable AP1000 deployment can be organized beyond the two units completed at Plant Vogtle. The proposed first phase is more modest: two reactors, which would still require site-specific reviews, engineering, financing, grid arrangements and construction contracts. The gap between a six-unit concept and a permitted, financed first unit is where project schedules are made or lost.

A recent regulatory development could help on design review, but it should not be confused with approval of Prosperity One. On October 14, the NRC renewed the AP1000 certification and incorporated lessons from the construction and operation of Vogtle Units 3 and 4. The agency said it had reviewed and approved nearly 200 license amendments during those projects; incorporating relevant changes into the certified design may reduce duplicate review in future applications. The NRC also made clear that each applicant still needs site-specific environmental, safety and security approvals.

That distinction matters particularly for a greenfield campus. A standardized reactor design can narrow one part of the licensing task, but it does not establish that a proposed site is suitable, that transmission infrastructure can carry the output, or that the project has a bankable route to market. Prosperity One will need to answer all of those questions in parallel if its stated schedule is to hold.

Background

The AP1000 is a pressurized-water reactor design built by Westinghouse. It is already operating at Vogtle in Georgia, where Units 3 and 4 entered commercial service in 2023 and 2024. The new Kentucky proposal draws on that fleet experience, although construction performance at one site does not guarantee the same cost or schedule at another.

The Nuclear Company has also been building a broader role in U.S. reactor development. In May, it announced a partnership with Brookfield to develop Westinghouse reactor projects and project-manage completion of the partially built VC Summer units in South Carolina, as reported by World Nuclear News. The Kentucky proposal would be a different kind of undertaking: a new site with no existing nuclear plant infrastructure.

For readers following the wider pipeline, NNN has covered Westinghouse's planned Columbia fuel-fabrication expansion and the AP1000 design and deployment model. Both illustrate pieces of the supply chain and technology case; neither resolves Prosperity One's local approvals, financing or construction readiness.

What's next

The next meaningful milestones are site characterization, environmental assessment, transmission studies and the start of formal engagement with the NRC. The NRC's combined-license process reviews an applicant's qualifications, design safety, environmental impacts, operational programs and site safety, with opportunities for public participation. The agency's current list of applications shows that a design certification and a site license are separate regulatory steps.

The company's 2028 target is therefore a schedule objective, not a guaranteed start date. Before ground-breaking, the project will need a defined first phase, an application strategy and the approvals required for the chosen site. The clearest near-term signal will be whether Prosperity One moves from an announcement into documented site work and a formal regulatory process.
