The United States has brought only two new large nuclear reactors online in the past three decades, despite repeated attempts to revive the industry. The Department of Energy’s decision to make $17.5 billion in loans available for ten new reactors represents the most significant federal effort in years to reverse that trend and determine whether standardized deployment can finally overcome the cost overruns and delays that have defined modern U.S. nuclear construction.
Energy Secretary Chris Wright said the financing package could shorten project timelines by as much as three years by supporting the early procurement of critical long lead components. The initiative would back five separate projects, each hosting two large reactors based on Westinghouse’s AP1000 design.
The AP1000 currently occupies a unique position in the American nuclear landscape. It remains the only large reactor design licensed for operation in the United States, a reality that narrows technological risk but also concentrates federal support around a single platform. Each reactor produces roughly 1.1 gigawatts of electricity, sufficient to power more than 800,000 homes under typical consumption patterns.
The financing structure reflects lessons learned from previous nuclear failures. Rather than lending directly to Westinghouse, the Department of Energy intends to channel funds through five special purpose vehicles. According to officials, Westinghouse and its utility partners must collectively contribute nearly $1 billion in equity to each project before federal loans become available, ensuring substantial private capital participation.
That requirement attempts to balance public support with market discipline. The bankruptcy of former AP1000 developer Westinghouse in 2017 and the multibillion dollar cost overruns at the Vogtle expansion in Georgia continue to shape investor perceptions of large nuclear projects. Vogtle Units 3 and 4 ultimately entered commercial operation years behind schedule and at costs exceeding initial estimates by tens of billions of dollars.
Federal policymakers are betting that repetition and standardization can alter that trajectory. Building ten reactors using a single design across multiple sites could create manufacturing efficiencies, stabilize supply chains, and reduce engineering uncertainties that have historically inflated costs. The approach mirrors deployment models used successfully in countries such as South Korea and China, where standardized reactor fleets have delivered more predictable outcomes.
The economic rationale has gained additional momentum from the rapid expansion of artificial intelligence infrastructure. Technology companies seeking reliable, carbon free electricity supplies have emerged as a new constituency for nuclear power. Data center growth is placing unprecedented pressure on regional grids, forcing utilities and policymakers to reconsider firm generation assets capable of operating independently of weather conditions.
Microsoft and Google have already committed support to nuclear restart projects at Three Mile Island in Pennsylvania and the Duane Arnold facility in Iowa. Yet no major technology company has signed a long term agreement underwriting the construction of a completely new large scale nuclear plant.
The Trump administration expects that dynamic to change. Officials anticipate that large technology firms will enter into long duration power purchase agreements with the new projects, creating stable revenue streams capable of supporting financing structures. Such arrangements would mirror renewable energy procurement strategies that technology companies have employed for more than a decade, albeit with substantially different capital requirements and development timelines.
President Donald Trump’s executive order in May 2025 established an ambitious target of initiating construction on ten large reactors by 2030. Westinghouse subsequently committed to supporting that objective, though significant uncertainties remain regarding permitting, workforce availability, component manufacturing capacity, and final site selection.
The Department of Energy has not disclosed the locations under consideration, indicating only that candidate sites are geographically distributed across the country. Existing nuclear sites with established infrastructure and regulatory familiarity are widely viewed as the most likely candidates, reflecting broader industry efforts to reduce development risks.
