How Many Nuclear Power Plants Are in the United States?

As of 2024, the United States operates 94 commercial nuclear reactors spread across 54 operating nuclear power plants. Please note that each nuclear plant has at least 1 nuclear reactor but may have more, and a reactor is not in itself a plant. These plants are responsible for producing nearly 20% of the nation’s electricity, making nuclear power a significant contributor to the country’s energy mix. Despite this, the number of operational reactors has declined from a peak in the 1990s, when over 110 reactors were in service. This reduction is due to a combination of factors, including plant aging, rising maintenance costs, and competition from cheaper energy sources such as natural gas and renewables.

While 94 reactors may seem sufficient, nuclear power’s current share of U.S. electricity generation falls short of what would be needed in a fully decarbonized grid. Achieving a significant reduction in carbon emissions, especially under net-zero goals, would require the construction of many more reactors. Projections vary, but experts suggest that a transition to a low-carbon energy future could require the building of dozens, if not hundreds, of new reactors in the coming decades. Significant additional nuclear capacity will be required to meet rising electricity demands and support net-zero emissions goals by 2050.

The need for additional nuclear plants is underscored by the retirement of existing coal plants, which have traditionally supplied much of the country’s baseload power. By transitioning these coal plants into nuclear sites, the U.S. could reduce emissions while leveraging existing energy infrastructure.

The Need for New Nuclear Power Plants

A key aspect of the nuclear transition is the development of new nuclear plants to meet the country’s growing energy demands and climate goals. As older plants reach the end of their lifespans, new reactors—particularly advanced designs like Small Modular Reactors (SMRs)—will be essential. SMRs are easier and faster to build than traditional large reactors, thanks to their modular design, which allows parts to be manufactured off-site and assembled more efficiently.

New nuclear power plants will require heavy investment in construction materials, infrastructure, and skilled labor. The complexity of these projects involves advanced engineering, from the reactor core itself to cooling systems, radiation shielding, and seismic-resistant structures. The construction of nuclear plants also demands robust quality control and compliance with stringent safety standards, adding further layers of complexity.

What Goes into Renovating Dormant Plants for Coal-to-Nuclear Conversion?

Repurposing dormant or shuttered nuclear plants presents a more cost-effective option for boosting nuclear power capacity compared to building new facilities, especially when considering the performance and operational capacity of existing reactors. Renovating these facilities involves modernizing aging infrastructure to meet current safety standards, upgrading reactor technology, and extending the operational life of the reactors.

Construction firms involved in renovating dormant plants will face several challenges, such as dealing with radioactive materials left over from previous operations, updating old systems to meet modern regulatory requirements, and reinforcing structures to withstand natural disasters.

Renovating dormant sites also aligns with sustainability goals, as it minimizes the need for new land development and leverages existing infrastructure. BuildCentral’s data on dormant nuclear sites and other energy infrastructure projects can help contractors and developers identify opportunities for renovations and upgrades.

What Are Nuclear Power Plant Site Selection Considerations?

Choosing the right location for nuclear power plants is a critical component of the transition. Several factors must be considered, including environmental, economic, and logistical concerns. For new nuclear plants, proximity to cooling water sources, seismic stability, and distance from populated areas are essential. A floating nuclear power plant, like Russia’s Akademik Lomonosov, offers an innovative solution by providing power to remote regions. Existing infrastructure, like transportation and power grid connections, also plays a role in site selection, as does the ability to safely store or transport nuclear waste.

One strategy gaining momentum is the conversion of former coal plant sites into nuclear facilities. These sites already have grid connections, cooling systems, and large plots of land that meet many of the requirements for a nuclear plant. Coal plants also tend to be located near the industrial areas they once served, which are often prime candidates for energy-intensive industries. By transitioning coal plants to nuclear, the U.S. can accelerate its decarbonization efforts while reusing existing infrastructure.

Consequences of Nuclear Expansion for Solar, Wind, and Other Cheaper Forms of Energy

The expansion of nuclear power in the U.S. will have significant implications for other renewable energy sources like solar, wind, and hydropower. The World Nuclear Association reports significant nuclear expansion could potentially slow down the development of solar and wind power by reducing the perceived need for additional renewable energy sources due to nuclear energy’s ability to provide a large, reliable baseload of electricity, potentially leading to less investment and market share for solar and wind, even if they are considered cheaper per unit of energy in some scenarios.

While nuclear energy offers a reliable, carbon-free option for baseload power, it also comes with high upfront costs and long construction timelines. In contrast, solar and wind are often cheaper to install and can be deployed more quickly, making them attractive for meeting immediate energy demands. As nuclear expansion progresses, several potential consequences for these cheaper renewable energy sources are likely:

Competition for Investment

One of the most immediate effects of nuclear expansion could be increased competition for energy-sector investment. Nuclear power plants are capital-intensive projects with long lead times, often requiring billions of dollars and many years to complete. Solar and wind projects, by contrast, tend to have lower capital costs and shorter timelines, allowing investors to see quicker returns. As the U.S. government and private investors decide where to allocate funds, nuclear energy could draw resources away from solar, wind, and other renewables, potentially slowing their growth.

Grid Integration and Energy Mix

Nuclear power provides steady, reliable baseload energy, which complements the intermittent nature of solar and wind power. Expanding nuclear capacity could help stabilize the grid and reduce the need for backup power from fossil fuels, which are often used to fill gaps when the sun isn’t shining or the wind isn’t blowing. However, if nuclear expansion is prioritized, it may reduce the urgency of large-scale energy storage solutions—like batteries—that are needed to store excess solar and wind energy for use during off-peak times.

Policy and Regulatory Shifts

As nuclear energy becomes a bigger part of the U.S. energy mix, there could be shifts in policy and regulatory priorities. While the federal government currently provides incentives for both nuclear and renewable energy sources, a large-scale nuclear expansion could shift more regulatory focus and financial incentives toward nuclear. This might result in reduced subsidies or tax credits for solar and wind projects, affecting their growth and competitiveness.

Land and Resource Use

Solar and wind power require substantial land areas for large-scale deployments, particularly in the case of solar farms and wind turbines. Nuclear power, with its higher energy density, can produce far more electricity per acre of land, which could make it a preferred option in land-constrained regions. As more land is allocated for nuclear plants, especially if former coal plant sites are converted, it could limit the availability of prime locations for solar and wind projects. This could push developers to seek out less optimal sites, potentially increasing costs for renewables.

Nuclear Energy and the Environment

Nuclear energy stands out as a clean and sustainable source of electricity, playing a crucial role in reducing greenhouse gas emissions and combating the advance of climate change. Unlike fossil fuels, nuclear power plants do not emit greenhouse gases or other pollutants during their operation, promoting sustainability. This makes them a much cleaner alternative for generating electricity. According to the Nuclear Energy Institute, nuclear power plants in the United States have prevented the release of over 2.4 billion metric tons of carbon dioxide since 1973, significantly contributing to environmental protection.

However, the environmental benefits of nuclear energy come with their own set of challenges. One of the primary concerns is the storage and disposal of nuclear waste. The nuclear industry is actively working on developing new technologies and strategies to address these issues. Innovations in waste management and disposal methods aim to minimize the environmental impact of nuclear energy, ensuring that it remains a sustainable option for the future. The sustainable construction and operation of nuclear plants is paramount in ensuring a environmental harmony.

The cost of ignoring climate change in regards to nuclear construction and operation can be detrimental. For example, a report issued by the French Court of Auditors highlighted the issues regarding the safety and operation of nuclear power plants because of the increasingly unstable supply of the water necessary for cooling reactors. Forced shutdowns of reactors only occur rarely, usually in the summer, for now, but the French court warns that such events are set to become three to four times more frequent by 2050. In the U.S., many nuclear plants are located near coasts or large bodies of water. If water levels rise or fall, the consequences could range from operations interruptions to the desolation of entire nuclear plants, potentially causing environmental disasters.

Climate Change Impacts on Nuclear Power Plants

Climate change presents significant challenges to the operation and safety of nuclear power plants. Rising temperatures can strain cooling systems, while sea-level rise threatens the integrity of coastal facilities. Extreme weather events, such as hurricanes and floods, pose additional risks, potentially disrupting operations and causing damage to infrastructure.

The nuclear industry is proactively addressing these challenges by developing advanced cooling systems and implementing climate-resilient design principles. These measures aim to ensure that nuclear power plants can continue to operate safely and efficiently in the face of changing environmental conditions. By adapting to the impacts of climate change, the nuclear sector can maintain its role as a reliable and sustainable source of electricity.

The AI industry is already having to confront obvious energy limitations. The Guardian reports Google has ordered six or seven small nuclear reactors from California’s Kairos Power. Google hopes the deal will provide a low-carbon solution to power data centers, which require huge volumes of electricity. 

Michael Terrell, the senior director for energy and climate at Google, said: “The grid needs new electricity sources to support AI technologies that are powering major scientific advances, improving services for businesses and customers, and driving national competitiveness and economic growth.”

Regulatory Framework and Policy

The regulatory framework and policy landscape for nuclear energy are critical for ensuring the safe and sustainable construction of nuclear power plants. In the United States, the Nuclear Regulatory Commission (NRC) plays a pivotal role in regulating the nuclear industry. The NRC sets stringent safety standards and regulations, conducting regular inspections and audits to ensure compliance and the safe operation of nuclear power plants, being sure to promote sustainability.

The Inflation Reduction Act, signed into law in 2022, has provided a significant boost to the nuclear industry. This legislation offers substantial funding and incentives for the development of new nuclear reactors and technologies. It aims to promote the advancement of advanced nuclear reactors and Small Modular Reactors (SMRs), supporting the deployment of new nuclear power plants across the country. While the Act did carry provisions for renewable energy, it did so while also requiring investment in domestic oil, gas, & fracking operations on which the renewable energy projects were contingent.

Overall, a robust regulatory framework and supportive policies are essential for the growth and sustainability of nuclear energy. They ensure that nuclear power remains a safe, reliable, and environmentally friendly option for meeting the nation’s energy needs.

Public Perception and Acceptance

Public perception and acceptance are vital to the successful development of new nuclear power plants. Addressing concerns about safety, waste disposal, and environmental impact is essential to gaining public trust. The development of advanced nuclear technologies, such as SMRs and Generation IV reactors, offers improved safety and efficiency, which can help to increase public confidence in nuclear energy.

Engaging with local communities and stakeholders is also crucial. The nuclear industry must provide education and training on the benefits and risks of nuclear energy, fostering a better understanding and acceptance of this critical energy source. By addressing public concerns and demonstrating the safety and sustainability of modern nuclear power, the industry can build the support needed for future growth and development.
