Westinghouse and U.S. Department of Energy Collaborate to Accelerate Large-Scale Nuclear Power Expansion
Westinghouse Electric Company has announced plans to partner with the U.S. Department of Energy’s (DOE) Office of Energy Dominance Financing (EDF) through a major initiative designed to strengthen the nation’s nuclear energy supply chain and accelerate the deployment of new nuclear power generation across the United States.
The initiative, known as the American Nuclear Supply Chain Loans program, represents a significant step toward rebuilding domestic nuclear manufacturing capabilities and supporting the large-scale construction of advanced nuclear power plants. Under the program, the DOE has issued a conditional commitment of up to $17.5 billion in obligated funds that would be used to finance the procurement of critical long-lead-time items (LLI) required for the construction of as many as ten Westinghouse AP1000® nuclear reactors.
The AP1000 reactor is currently the only fully designed, licensed, and commercially operating advanced nuclear reactor technology in the United States. By enabling the early purchase of essential equipment and components, the financing initiative is expected to reduce project development timelines by as much as three years while improving supply chain coordination and manufacturing efficiency.
The announcement comes at a time when policymakers, utilities, and technology companies are increasingly focused on ensuring reliable and affordable energy supplies to support economic growth, industrial development, and the rapid expansion of energy-intensive sectors such as artificial intelligence and advanced manufacturing.
According to Westinghouse President and Chief Executive Officer Dan Sumner, large-scale investment in nuclear energy infrastructure is critical to maintaining America’s competitive position in emerging industries while strengthening domestic energy security.
“America has always achieved its greatest successes when it invests in the future and builds at scale,” Sumner said. “If the nation wants to remain a leader in artificial intelligence, advanced manufacturing, and other industries that will shape the coming decades, it must ensure access to reliable baseload power. Expanding industrial-scale nuclear energy can support long-term economic growth, create thousands of high-quality jobs, strengthen domestic supply chains, and revitalize communities across the country.”
The proposed financing framework is designed to support the deployment of a fleet of AP1000 reactors rather than individual standalone projects. Westinghouse plans to collaborate with up to five eligible utility companies or energy developers, with each participating project expected to include two AP1000 reactor units.
To advance the initiative, Westinghouse has already signed Letters of Intent with seven potential partners that have identified suitable locations for future reactor development. These agreements demonstrate growing interest in expanding nuclear generation capacity as utilities seek dependable, carbon-free electricity sources capable of meeting rising energy demand.
One of the most significant challenges facing large-scale nuclear construction projects is securing long-lead-time components. These specialized items often require years of manufacturing, testing, and certification before they can be delivered to construction sites. Examples include reactor pressure vessels, steam generators, turbine components, and other critical equipment that form the foundation of a nuclear power plant.
By providing financing support for the early procurement of these materials and components, the DOE initiative aims to eliminate supply bottlenecks, improve project certainty, and enable manufacturers to plan production more effectively. Early procurement can also reduce overall project costs by allowing suppliers to benefit from economies of scale and long-term production schedules.
The conditional commitment from the DOE reflects the federal government’s intention to support the initiative; however, several important milestones remain before any financing can be finalized. Westinghouse and the Department of Energy must satisfy a range of technical, legal, environmental, and financial requirements before definitive financing agreements can be executed and funds can be disbursed.
These evaluations are intended to ensure that supported projects meet federal standards related to safety, environmental protection, financial viability, and project readiness. Once completed, the financing could provide a substantial boost to the development of new nuclear generation capacity in the United States.
The AP1000 reactor technology is a cornerstone of Westinghouse’s strategy for expanding nuclear energy globally. Classified as a Generation III+ reactor, the AP1000 incorporates advanced safety features and innovative engineering solutions that distinguish it from earlier generations of nuclear power plants.
Among its key characteristics is a fully passive safety system that relies on natural forces such as gravity, natural circulation, and compressed gases to maintain reactor safety during emergency situations. Unlike traditional systems that depend heavily on active equipment and external power sources, passive safety systems are designed to operate without operator intervention or additional electrical power.
The AP1000 also utilizes a modular construction approach that allows major plant components to be manufactured in factories and assembled on-site. This methodology can improve construction efficiency, reduce labor requirements, and help standardize project delivery across multiple reactor units.
Another advantage of the AP1000 design is its compact footprint relative to its power output. The reactor delivers substantial generating capacity while requiring less land compared with many competing technologies, making it attractive for utilities seeking efficient use of existing or new nuclear sites.
The technology has already demonstrated successful commercial operation. Six AP1000 reactors are currently operating worldwide and have established strong records for reliability, availability, and operational performance. These units have helped validate the design and provide valuable experience for future deployments.
Beyond the reactors already in service, global demand for the AP1000 continues to grow. Fourteen additional units are currently under construction, while five more reactors are under contract. This expanding project pipeline reflects increasing international confidence in advanced nuclear technologies as countries pursue energy security objectives and long-term decarbonization goals.
Westinghouse’s AP1000 technology has also been selected for major nuclear development programs in several countries. Poland has chosen the reactor as part of its efforts to establish a modern nuclear power sector and reduce dependence on fossil fuels. Ukraine has also selected AP1000 technology for future nuclear expansion projects, supporting the country’s long-term energy resilience strategy. In Bulgaria, plans are advancing to deploy AP1000 reactors as part of efforts to modernize and expand national generating capacity.
In addition to these confirmed projects, the AP1000 is being evaluated for potential deployment at multiple sites across Europe, the Middle East, and North America. Growing global electricity demand, combined with increasing emphasis on clean and reliable energy sources, continues to drive interest in advanced nuclear solutions.
The partnership between Westinghouse and the Department of Energy highlights a broader national effort to rebuild domestic nuclear capabilities, strengthen manufacturing capacity, and establish a scalable framework for future reactor deployment. If successfully implemented, the initiative could accelerate the construction of a new generation of nuclear power plants, support economic development, create skilled jobs, and provide the reliable electricity needed to power America’s future growth.
As energy demand continues to rise and the need for dependable, carbon-free generation becomes increasingly important, the proposed investment in AP1000 reactor deployment represents a significant milestone in the ongoing expansion of the U.S. nuclear energy sector.
