States in the U.S. are once again actively competing to attract nuclear technology innovation and new nuclear builds to their regions. Within the last few years, energy demand has begun to grow. States’ efforts to transition to carbon-free energy sources are at risk unless additional sources of clean base load power can be obtained. This is what is stimulating considerable legislative activity in the states to figure out how to build advanced nuclear.
Historically, some thirty states built and operated traditional nuclear reactors. By the late 80s, sixteen states enacted some form of ban against further nuclear builds, in particular because of the federal government’s failure to fulfill its commitment to develop a waste repository. Some these states even worked to shutter the nuclear power plants that they had built, due to the protests that arose during the 1990s through to the late 2010s.
But with a growing awareness that nuclear is the safest form of energy ever developed and growing pressure to attract the data centers being built by tech hyperscalers—who are happy to buy reliable, clean nuclear power—states are circling back to figure out their strategies. Nuclear power has the benefit of having high capacity factors, stable prices and zero carbon. These features make it highly attractive for desperate energy buyers looking to purchase reliable carbon-free power. All of a sudden, customers are appearing willing to pay to re-start shuttered nuclear plants, complete nuclear builds halted prematurely and even place quantity orders for next-generation designs.
So, after a hiatus, we are again working to track this activity by state. Information is being added on a continuous basis, so please check back for updates. (For information about US State-by-State Electricity Sources, please see Hannah Ritchie’s excellent Data Explorer, based on data from Ember Climate.)
We are pleased to provide this state-by-state listing of the legislation being proposed and passed across five main categories since 2016. These include: Zero-Emission Credit programs to protect viability of existing plants; Repeals of nuclear bans on construction of new nuclear; Funding of Feasibility Studies for deployment of new nuclear; and support for deployment of Advanced nuclear and SMRs or support for Fusion nuclear.

Alabama, the nation’s fourth-largest producer of nuclear-generated electricity, operates two nuclear power plants that supply roughly one-third of the state’s electricity. In December 2025, the Nuclear Regulatory Commission approved subsequent license renewals for all three reactors at the Browns Ferry Nuclear Plant, authorizing operation into the 2050s and confirming the long-term durability of Alabama’s existing nuclear fleet.
State-level nuclear policy actions—particularly with respect to next-generation technologies—remain limited but directionally supportive. In April 2025, lawmakers adopted SJR 67, which endorsed the secure storage of uranium-233 (U-233) in the state and called for a task force to evaluate related infrastructure, workforce needs, and federal coordination. The resolution highlighted the potential of advanced nuclear technologies to deliver safer, more economical, and environmentally sustainable energy, as well as opportunities for high-quality jobs and federal investment.
These actions followed HR 84 (2017), which encouraged bipartisan engagement around advanced reactor development. While Alabama has demonstrated strong institutional and operational capability through its existing fleet, the state has not yet established siting policies, deployment programs, or funding mechanisms for new nuclear construction. As a result, current activity remains focused on sustaining legacy assets rather than advancing new nuclear deployment.

Alaska has positioned itself as one of the earliest states to prepare for microreactor deployment. In 2022, lawmakers passed SB 177, amending AS 18.45 to require the Department of Environmental Conservation (DEC) to adopt siting and permitting regulations for microreactors. DEC finalized those rules in August 2023(18 ACC 87), including provisions for community engagement and requirements for “unorganized” boroughs. These regulations were built on the 2010 Sustainable Energy Act (SB 220), which established a statewide policy treating nuclear on equal terms with other sources and opened access to the state’s Power Project Fund.
Recent developments have moved from policy to practice. In mid-2025, the U.S. Air Force selected Eielson Air Force Base near Fairbanks as the first military site for a microreactor installation and issued a Notice of Intent to Award to Oklo, Inc. for a planned 5 MW unit, pending NRC licensing. If completed, it would be the first demonstration of a commercial microreactor on U.S. soil, placing Alaska at the forefront of small-scale nuclear deployment.

Arizona is home to Palo Verde, the nation’s second-largest nuclear power plant and a major source of the state’s electricity. While no new reactors have been built since Palo Verde, policymakers and utilities have started exploring the potential role of small modular reactors, particularly at sites of retiring coal plants or large industrial facilities. A recent proposal, HB 2774 (2025), would have exempted certain SMR projects from standard environmental and zoning reviews, but was vetoed by Governor Katie Hobbs, reflecting continued political division on nuclear expansion.
At the same time, Arizona’s utilities—including APS, SRP, and TEP—are actively positioning for federal support, applying jointly for DOE funding to study SMR deployment and participating in national tenders. The Arizona Corporation Commission has also launched a formal inquiry into nuclear’s role in the state’s clean energy mix, showing institutional interest in keeping nuclear on the table even amid policy setbacks.

Arkansas has gradually shifted from nuclear research toward early-stage policy preparation. In 2019, lawmakers supported a study on commercial reuse of spent fuel, followed in 2023 by the creation of the Arkansas Nuclear Recycling Program under the Department of Environmental Quality. In 2025, the Legislature enacted two measures that signaled a more proactive stance: HB 1572 requires a comprehensive feasibility study of new nuclear generation—including siting criteria, workforce needs, and economic impacts—while SB 307, the Generating Arkansas Jobs Act, authorizes utilities to recover costs for advanced energy projects (explicitly including nuclear) and obliges them to monitor and evaluate SMRs in their long-term planning.
Following the establishment of HB 1572, Arkansas formally hired Excel Services Corporation (EXCEL) to conduct the feasibility study (mandated by the aforementioned bill). The consultancy is expected to provide a full report on siting, workforce, and economic impacts within 10 months of contract start date.
Arkansas still lacks siting or procurement mandates for new reactors, but these steps point toward a deliberate move from exploratory studies toward positioning the state for potential advanced nuclear deployment in the future.

Alone among the most populated, industrial, and progressive U.S. states, California remains mired in antiquated antinuclear politics. Although there is a large fraction of advanced nuclear innovation happening at startups located in California, California’s moratorium on new nuclear plants will force these ventures to seek alternative states in which to build their technologies. California’s leadership has shown no interest in competing to win the race to attract all of the talent, federal funding, jobs, and economic development that will accompany the growth of this innovative sector, and, by all appearances, the state has now fallen behind Texas, Wyoming, Illinois, New York, and even Connecticut.
But, there are signs of attitudinal shifts happening even in deep blue California. Both California’s progressive Governor, Gavin Newsom, who for years worked to force the retirement of Diablo Canyon, and the state’s legislature reversed their decisions at the last minute and delayed the closure of the nuclear facility for five more years. They recognized, if reluctantly, that the plant had reliably provided almost 20% of the state’s zero-emission power and 8% of its electricity for decades. Shutting it down would expose the state to dire and life-threatening power outages without the plant’s high capacity-factor reliability and highly differentiated, non-intermittent generation. It would also set back progress on the state’s climate goals.
Sadly, despite several attempts over the years by elected legislators to bring the state into competitive parity with the country and do away with its 49-year-old nuclear moratorium, make exceptions for SMRs, and/or conduct feasibility studies about SMRs, these bills have not made it out of committee. Thus, the state appears poised to miss out on the energy revolution made possible by next-generation nuclear, even with many advanced nuclear ventures being located in California.
In the ongoing effort to extend the life of the Diablo Canyon Power Plant, the California Coastal Commission has ordered PG&E to commit to a larger coastal land conservation package—over 3,000 acres—as a condition for approving the plant's 20-year license extension. The commission is scheduled to vote on the required coastal development permit before the end of 2025.

Colorado has historically been wary of nuclear power, shaped by decades of political opposition and concerns over uranium mining. The state has no operating reactors, and until recently nuclear was excluded from clean energy planning. In 2023, lawmakers authorized a study (HB 23-1247) on whether advanced nuclear could replace retiring coal plants, but the work remained exploratory.
That stance shifted in 2025 when Governor Jared Polis signed HB 25-1040, officially classifying nuclear as a clean energy resource under state law. The change makes nuclear eligible for state clean energy incentives and allows utilities and private companies to begin investing in advanced nuclear technologies, though it does not mandate deployment. The move, driven by bipartisan support and grassroots pressure, signals that nuclear will now be considered alongside renewables and storage in Colorado’s long-term energy strategy.
Key Legislation & Policy Actions
Connecticut has a state-wide ban, but passed an exception in 2022 that allows more nuclear construction at the site of the state’s one operating nuclear power plant, the Millstone Power Station, which generates a third of the state’s electricity. This specifically allows Dominion Energy to build advanced nuclear at the Millstone site. Dominion has shown interest in SMRs and recently announced a deal with X-energy to build its advanced design, in partnership with Amazon.

Delaware, while the second smallest state, is home to more than two-thirds of the nation’s Fortune 500 companies due to its favorable tax climate. It produces less energy than any other state yet consumes nearly 100 times more than it generates. Despite this, Delaware has not advanced any nuclear-related policies or initiatives. The state has no operating nuclear facilities, has not introduced legislation for small modular reactors or advanced nuclear technologies, and continues to focus its clean energy strategy on offshore wind, solar, and efficiency measures.
Key Legislation & Policy Actions
Florida has taken its first meaningful steps toward exploring advanced nuclear power. In 2024, the state enacted HB 1645, which mandated the Public Service Commission (PSC) to evaluate the feasibility of advanced nuclear technologies, including small modular reactors. The PSC delivered its Advanced Nuclear Power Feasibility Report in March 2025, offering technical and economic analysis, recommending potential partnerships, particularly with military installations, and advising paths toward deployment.
The report also emphasized Florida’s heavy reliance on natural gas, which accounts for about 75% of its electricity generation (vs. nuclear’s 11%) and suggested that SMRs could provide a valuable hedge against fuel price volatility and grid vulnerability. While no siting or deployment policy has been established, these actions mark the first formal move to consider nuclear in Florida’s long-term clean energy planning.

Georgia’s nuclear profile is anchored by the completion of Plant Vogtle Units 3 and 4 — the first newly built commercial reactors in the U.S. in more than 30 years and now the largest nuclear power plant in the country, with a generating capacity north of 4,500 megawatts. The outcome was shaped by earlier laws: SB 31 (2009) authorized utilities to recover financing costs from ratepayers during construction, a mechanism that helped sustain Vogtle through years of overruns. Nearly a decade later, SB 355 (2018) closed that option for future projects, reflecting concerns about cost exposure.
Nevertheless, each new unit delivers significant value, producing carbon-free electricity sufficient to power about half a million homes and contributing to a measurable reduction in the state’s emissions intensity. Georgia has not promoted policies for advanced reactors, with its stance centered on large-scale builds rather than next-generation designs.

Hawaii has one of the most restrictive nuclear policies in the U.S., anchored in Article XI, Section 8 of its Constitution, which prohibits the construction of nuclear fission plants without a two-thirds vote of both legislative chambers.
No nuclear facilities have ever been built in the state, and nuclear has been excluded from its energy strategy, which instead focuses on achieving 100% renewable electricity by 2045 through solar, wind, and geothermal.
Public debate has focused on renewable integration and reducing reliance on imported petroleum, though nuclear has recently entered the conversation. In 2024, lawmakers introduced a constitutional amendment (HB 1741) to repeal the two-thirds approval requirement, but the measure did not advance to voters. In 2025, legislators enacted SB 1588, establishing a Nuclear Energy Task Force within the Hawaii State Energy Office. The task force is charged with evaluating nuclear’s potential role and must deliver an interim report before the 2026 session. While the constitutional restriction remains in force, this represents Hawaii’s first formal review of nuclear power in decades.

Idaho has emerged as one of the most active states in advanced nuclear development, largely defined by the work of the Idaho National Laboratory (INL). The Legislature has consistently supported nuclear’s role in the state—from a 2020 resolution recognizing its emissions-free benefits to a 2023 law expanding the statutory definition of “clean energy” to include nuclear. In 2024, lawmakers reinforced INL’s role by formally supporting the newly formed Idaho Advanced Energy Consortium.
At the project level, Idaho is now home to several first-of-kind demonstrations. In July 2025, the U.S. Department of Energy conditionally selected Radiant’s Kaleidos microreactor for testing at INL’s new DOME facility, marking what is on its way to becoming the first new U.S. reactor design to be tested in that environment. Around the same time, Oklo advanced its 15 MW Aurora reactor into pre-construction, while Sawtooth Energy proposed a 462 MW NuScale-based SMR project near Jerome, though its viability remains uncertain. INL itself has broadened its experimental portfolio to include MARVEL, Project Pele, and the Aalo-X reactor, and even partnered with Amazon Web Services to deploy AI tools for reactor modeling and licensing.
In September 2025, Governor Brad Little signed Executive Order 2025-09 to formally create the Idaho Advanced Nuclear Energy Task Force, with the aim to assess, recommend, and support strategies that advance the state's leading role in nuclear energy innovation. The Task Force, supported by staff from the Governor’s Office of Energy and Mineral Resources (OEMR) and the Idaho National Laboratory (INL), brings together government, industry, utility, education, workforce development, and tribal leaders to focus on smart policy, responsible deployment, workforce growth, and long-term energy security. In February 2026, the Task Force convened its first inaugural meeting at the Idaho State Capitol, hosting: the State Governor (Brad Little), the DOE's Office of Nuclear Energy, the INL, the OEMR, and reactor developers Aalo Atomics, Oklo, and Antares. The next meeting is scheduled for May 21, 2026.

One of the largest nuclear generating states, Illinois, produces 53% of its electricity (and 90% of its clean energy) from nuclear power. The state has moved decisively to encourage new construction. While lawmakers had previously passed HB 2473 in 2023, which partially lifted the state's moratorium to permit SMRs ≤300 MW, the most significant policy shift came in late 2025. In October 2025, the General Assembly passed the Clean and Reliable Grid Affordability Act (SB 25), which enacts a full repeal of the 30-year moratorium on new, large-scale nuclear reactors. On January 8, 2026, the bill was formally signed into law by Governor J.B. Pritzker, which also includes provisions for increased battery storage and expanded energy efficiency programs. This dramatic action positions Illinois to further encourage new nuclear development, including large-scale projects, in the race to meet net-zero goals.

Iowa has no operating nuclear facilities following the 2020 permanent shutdown of the Duane Arnold Energy Center, the state’s only commercial nuclear power plant. In August 2025, the Federal Energy Regulatory Commission (FERC) approved a waiver allowing NextEra Energy to move forward with plans to restart Duane Arnold by 2028–2029, subject to restoration of its NRC operating license. NextEra has begun preliminary recommissioning work and is in talks with potential buyers for the plant’s output.
Beyond Duane Arnold, state-level nuclear policy remains limited. Governor Kim Reynolds has proposed establishing a Nuclear Energy Task Force and expressed openness to include nuclear energy in the Iowa Energy Plan, but no new legislation has been enacted to date.

Kansas has one nuclear power plant, Wolf Creek Generating Station (co-owned by Kansas utilities but licensed by the NRC), which generates almost 20% of the state’s electricity. State policy has not actively promoted new nuclear development, but nuclear has been referenced in energy planning documents as a potential zero-carbon option.
A new bill, SB 274 (2025), would require the Kansas Corporation Commission to hire a consulting firm to conduct a technical and legal feasibility study on nuclear energy generation in the state, including designs, environmental implications, SMRs, workforce impacts, and economics. The bill was referred to the Senate Utilities Committee and did not proceed further.

Kentucky has moved from lifting its moratorium in 2017 to building a full policy framework for nuclear development. This was followed by incremental policy building: in 2023, lawmakers established a Nuclear Energy Development Working Group, and in 2024, enacted SB 198, creating the Kentucky Nuclear Energy Development Authority (KNEDA) to oversee siting, workforce training, and “nuclear-ready” community designations. Despite a gubernatorial veto, the bill passed with strong bipartisan support, and lawmakers appropriated $20 million to the University of Kentucky to bolster research and planning efforts.
Momentum accelerated in 2025. SB 179 launched the Nuclear Energy Development Grant Program, offering up to $2 million per award to nuclear projects under KNEDA’s oversight. That same session, HCR 22 formally recognized the importance of nuclear energy, tying Kentucky’s recent efforts to its earlier repeal of the moratorium. In August, General Matter signed a multi-decade lease at the DOE’s Paducah Gaseous Diffusion Plant to establish new uranium enrichment capacity, positioning western Kentucky as a potential supply chain hub.
Altogether, Kentucky has progressed from lifting restrictions to actively funding research, building institutions, and attracting industry partners. Its stance on nuclear has seen a major uplift, with an emphasis on innovation, supply chain infrastructure, and workforce preparation.

Louisiana is making modest but clear strides toward laying the groundwork for future advanced nuclear energy deployment. In 2025, the Legislature passed SB 127, which empowers the Louisiana Department of Environmental Quality (LDEQ) to establish an expedited permitting process for small modular reactors.
Complementing this, HR 249 (2025) sets up a state task force to study SMR policy and development opportunities. Another resolution, HR 212, directs the Department of Energy and Natural Resources and the Public Service Commission to examine the feasibility of transitioning to nuclear energy, evaluating its costs, risks, and benefits.
Legislation such as Act 462 (HB 692) extends the “green energy” designation under state law to include nuclear power, shifting state-level energy prioritization toward more reliable carbon-free sources.
In April 2025, Louisiana also joined a multi-state lawsuit challenging federal SMR licensing rules, aiming to reduce overly burdensome regulatory standards that hinder innovation.

Massachusetts has no operating nuclear plants after the permanent closure of Pilgrim Nuclear Power Station in 2019, which generated 20% of the state’s electricity. Since then, most legislative attention has focused on decommissioning oversight and public-health measures around Pilgrim, and the state has relied on offshore wind, hydro imports, and solar to meet its aggressive climate goals. However, in 2025, Gov. Maura Healey introduced the Energy Affordability, Independence & Innovation Act, which would allow the Commonwealth to secure new sources of power generation, energy storage, and demand response, including exploring “cutting-edge” nuclear technologies as part of an all-of-the-above approach. The proposal is pending in the Legislature.

Michigan has worked to protect and increase its nuclear power and sits at the forefront of resurgent state interest in nuclear energy. Michigan’s Democratic Governor, Gretchen Whitmer, worked to prevent the closure of the Palisades nuclear power plant. But, when a mechanical problem forced the plant’s sudden closure, the state legislature agreed to put $150 million toward the potential restart of Palisades, in what would be the US’s first-ever restart of a shuttered generating station. Under the Biden Administration’s Civil Nuclear Credit program, the plant subsequently received a $1.5 billion conditional loan commitment from the U.S. Department of Energy to help fund the repairs and restart, and potentially enable Holtec to build several SMRs on the site as well. Michigan lawmakers are also considering millions of dollars in incentives to develop and use the reactors, as well as train a nuclear industry workforce.
The comprehensive legislative package, House Bills 4124–4129, which offers R&D tax credits, SMR production credits, and workforce development grants and scholarships, passed the House in late 2025, demonstrating bipartisan support for positioning Michigan as a national nuclear leader.

Minnesota has one operating nuclear facility, the Prairie Island Nuclear Generating Plant, but has maintained a moratorium on new nuclear construction since 1994. Nuclear accounts for more than 20% of Minnesota’s electricity mix and 40% of the state’s carbon-free electricity, yet new development has been legally restricted. Over the years, proposals to lift or amend the ban have surfaced, but none have been enacted.
In 2025, lawmakers introduced multiple bills to repeal or relax the moratorium, including carve-outs for small modular reactors (≤300 MW). Some advanced through committee, but none have yet become law. Minnesota thus remains nuclear-dependent but politically constrained.
Key Legislation & Policy Actions
Mississippi hosts the Grand Gulf Nuclear Station, a single 1,400-MW reactor near Port Gibson that provides about 16% of the state’s electricity. Operated by Entergy, Grand Gulf is one of the largest single-unit nuclear reactors in the world.
The state has not introduced legislation to expand nuclear power or site advanced reactors. Policy discussions have focused instead on extending Grand Gulf’s license, which the NRC granted in 2020 through 2044. Mississippi’s clean energy planning remains minimal, with nuclear treated as part of the existing generation mix rather than an area for new development.
Key Legislation & Policy Actions
Missouri operates one nuclear plant, the Callaway Nuclear Generating Station, which provides about 14% of the state’s electricity. The facility has been in operation since 1984 and is licensed to run until 2044.
The state has not enacted new legislation to support advanced nuclear, and no proposals for additional nuclear facilities have advanced in recent years. Energy policy discussions in Missouri remain dominated by fossil fuel generation, with renewables and efficiency gaining attention. Nuclear has been treated as a stable, existing asset rather than a growth area.
Key Legislation & Policy Actions
Montana has gradually shifted from restrictive policies toward enabling a broader role for nuclear energy. In 2021, lawmakers repealed the requirement for statewide referenda on siting new nuclear facilities and commissioned a study on the feasibility of replacing coal plants with advanced reactors. More recently, though, the Legislature has moved into the nuclear fuel cycle. In 2025, HB 696 authorized uranium conversion and enrichment facilities, while HB 623 created a path for temporary in-state spent fuel storage under state and federal oversight.
Rather than focusing only on generation, Montana is now laying the groundwork across the full nuclear value chain. Its policies suggest interest in maintaining energy production from retiring coal sites while exploring whether advanced reactors and fuel-cycle infrastructure could anchor new economic activity.

Nebraska is beginning to integrate nuclear into its long-term clean energy planning. The Nebraska Public Power District (NPPD) announced in 2025 that it is evaluating options to expand nuclear capacity, including at the Cooper Nuclear Station, as part of its path to net-zero emissions. State regulators have also highlighted nuclear as a source of clean, firm baseload energy, underscoring its potential role in maintaining grid reliability.
Community-level planning is underway as well: sixteen sites across the state, including Kearney, are being studied for their suitability to host advanced reactors. Nebraska had already laid policy groundwork with LB 84 (2021), which made nuclear eligible for renewable energy tax incentives. The state has not yet committed to deployment, leaving its position exploratory rather than firmly pro- or anti-nuclear.
Key Legislation & Policy Actions
Nevada has historically been strongly opposed to nuclear development. The state’s political stance has been shaped by the long-running fight over the proposed Yucca Mountain nuclear waste repository, which Nevada leaders from both parties have opposed for decades.
While nuclear has been excluded from Nevada’s energy strategy, which prioritizes solar, geothermal, and storage, the state does host some educational and workforce initiatives. In 2025, NuScale Power and the University of Nevada, Las Vegas (UNLV) opened an Energy Exploration (E2) Center. The simulator provides hands-on training in nuclear science and reactor operations, intended to build a skilled nuclear workforce and expose students and community leaders to advanced nuclear technology.

New Hampshire has recently moved to more directly integrate nuclear into its energy framework. In 2025, lawmakers amended the state’s clean energy definition to include small modular reactors (HB 189) and adopted a resolution (HCR 2) declaring advanced nuclear development to be in the state’s interest. Additional measures that year updated regulatory definitions to cover SMRs and microgrids (SB 230) and considered — but did not finalize — legislation (HB 710) that would have allowed utilities to contract for up to 20% of their supply from advanced nuclear.
Earlier work laid the foundation for these changes: HB 543 (2022) established a commission to study next-generation nuclear technologies. While New Hampshire has taken several legislative steps toward positioning itself as receptive to advanced nuclear, no projects have yet been announced, leaving the state’s role more aspirational than operational.

New Jersey has been steadily active on both nuclear and fusion policy. Its Zero Emission Certificate (ZEC) program, established in 2018, has provided ongoing support for the state’s existing nuclear fleet at Hope Creek and Salem, with subsidies renewed through 2024. In 2024, PSEG announced plans to seek 20-year license extensions for those facilities. Alongside efforts to preserve the existing fleet, lawmakers have increasingly turned to advanced nuclear.
Since 2022, multiple bills have authorized or directed the Board of Public Utilities to regulate and incentivize small modular reactors, culminating in 2025 with SB 4423 and AB 4215, which allow siting at former nuclear facilities and establish new incentive structures. In November 2025, the New Jersey Energy Security and Affordability Act was introduced, proposing the creation of an Advanced Nuclear Development Fund (ANDF) to subsidize the construction of at least 1,200 MW of nuclear capacity. The bill also includes the creation of an Advanced Nuclear Energy Certificate (ANEC) program. The BPU also issued an RFI that year to evaluate nuclear’s role in meeting reliability and affordability goals, while a separate proposal (S3964) would create a competitive solicitation program prioritizing repurposed fossil and nuclear sites.
Fusion has also been a legislative focus, with S 219 and S 220 (2022) extending state incentives and establishing a promotion act for the sector. With activity on both fission and fusion fronts, New Jersey is experimenting with a broad policy toolkit to preserve its current fleet while testing whether advanced designs can fit into its clean energy portfolio.

New Mexico has no commercial nuclear power plants and has not advanced legislation to deploy new reactors. The state, which holds the second-largest known uranium reserves in the country after Wyoming, has an energy mix dominated by oil, gas, and renewables (especially wind and solar).
Nuclear activity in New Mexico is concentrated on the federal side: it hosts the Waste Isolation Pilot Plant (WIPP) near Carlsbad, the nation’s only deep geologic repository for transuranic nuclear waste from defense programs, and is home to major DOE facilities such as Los Alamos National Laboratory and Sandia National Laboratories.
The most contentious civilian issue has been the proposal by Holtec International to construct a consolidated interim spent fuel storage facility (CISF) in southeastern New Mexico. State leaders, including the governor, have opposed the project and passed legislation to block it. However, in June 2025, the U.S. Supreme Court ruled 6–3 that neither the State of Texas nor Fasken Land and Minerals had standing to challenge the NRC’s authority to license such facilities. The decision left NRC’s 2023 license to Holtec intact, potentially clearing a path for the project to proceed, though local and state opposition remains.
New Mexico’s broader clean energy strategy under the Energy Transition Act (2019) excludes nuclear, focusing instead on 100% renewable electricity by 2045. As such, while federal and private-sector nuclear activity is significant within the state, New Mexico itself remains reluctant to integrate nuclear into its clean energy portfolio.

New York has no statewide restriction but still has a narrow ban on new reactor development in the service territory of the Long Island Lighting Company, which covers Nassau, Suffolk, and some of Queens counties. Although New York’s disgraced former governor, Andrew Cuomo, forced the premature closure of Indian Point, which eliminated 80% of the then available clean energy for downstate New York, New York’s current Governor, Kathy Hochul, appears to be bringing nuclear back. She announced the state’s largest and most ambitious initiative to tackle the climate crisis with a new master plan. This includes a commitment of $1 billion by the state and specifically includes NYSERDA’s Blueprint for Consideration of Advanced Nuclear Energy Technologies, which outlines a process for the inclusion of advanced nuclear in the state’s Master Plan consideration process. Constellation Energy said that, with support from the New York State Energy Research and Development Authority, it would apply for a federal grant to seek an early site permit “for one or more advanced nuclear reactors” at its 1,907-MW Nine Mile Point Clean Energy Center near Oswego, New York.
Additionally, New York State will co-lead a multi-state initiative to support nuclear refurbishment and new nuclear development. This seems to place New York State firmly in the race to attract next-generation nuclear developers. New York joined the National Association of State Energy Officials’ Advanced Nuclear First Mover Initiative, or ANFMI.
In late 2025, the New York Power Authority (NYPA) officially issued two Requests for Information (RFIs) to both contractors and Upstate NY communities for a new, state-developed advanced nuclear plant. The RFI process is designed to select a site and identify a path to achieve at least 1 GW of advanced nuclear capacity with construction targeting a start date by 2033.
Moreover, in early 2026, Governor Hochul announced in her “State of the State” address the establishment of the “Nuclear Reliability Backbone for a Zero-Emission Grid” to add 4 GW of new nuclear capacity to a total of 5 GW, significantly expanding on the 1 GW procurement underway since June 2025. The “backbone” will be created through a new Department of Public Service process “to consider, review, and facilitate a cost-effective pathway to 4 gigawatts of new nuclear energy,” to support New York's Climate Leadership and Community Protection Act, which requires the state to achieve a 100% zero-emission electricity system by 2040. The State Energy Plan modeling shows that even at moderate deployment levels, adding 2.2 GW of nuclear power could cut 2040 compliance costs by about $26 billion, delivering major savings for ratepayers and taxpayers.

North Carolina is one of the leading nuclear power states in the U.S. It hosts five reactors across the Brunswick, McGuire, and Shearon Harris nuclear plants, operated by Duke Energy. Together, they provide roughly 30–35% of the state’s electricity, making the state the fifth-largest producer of electricity from nuclear power nationwide.
The state has not advanced legislation specific to any advanced nuclear technologies, but nuclear is central to Duke Energy’s Carbon Plan, filed with regulators in 2022 and updated in subsequent years. That plan calls for extending the life of existing plants and adding advanced nuclear as part of future resource portfolios to replace retiring coal plants and meet North Carolina’s carbon reduction mandates. In October 2025, Duke Energy filed its 2025 Carolinas Resource Plan, which, in response to unprecedented load growth, expanded its nuclear options to explicitly include the evaluation of Large Light-Water Reactor (LLWR) technology alongside SMRs, citing Shearon Harris and W.S. Lee as potential sites.
While political debate has focused more on renewables, natural gas, and offshore wind, nuclear remains a practical pillar of the state’s energy security. As of 2025, North Carolina’s role is pro-nuclear by practice rather than by new legislation, with advanced nuclear included as an option for future planning but not yet acted upon at the policy level.

North Dakota has no nuclear power plants and no state legislation for advanced nuclear projects. The state’s electricity mix is dominated by coal, natural gas, and wind, with coal still accounting for more than half of in-state generation.
Nuclear has occasionally entered policy discussions as part of efforts to diversify the energy mix and maintain grid reliability, particularly given the state’s dependence on fossil fuels. However, no bills specific to nuclear power have been introduced or enacted as of 2025. North Dakota’s energy strategy continues to emphasize carbon capture and storage for coal, expansion of wind capacity, and oil and gas development.

Ohio’s nuclear policy has been shaped by both controversy and cautious exploration of advanced technologies. The state operates two commercial nuclear plants, Davis-Besse and Perry, which together supply roughly 12% of Ohio’s electricity. In 2019, lawmakers passed HB 6, providing subsidies to preserve these plants, but the law later became mired in a major corruption scandal that led to partial repeal.
In 2022, the House advanced HB 434, known as the ANTHEM Act, which would have created the Ohio Nuclear Development Authority to pursue advanced nuclear deployment, including small modular reactors. Although it passed the House, the bill stalled in the Senate and did not become law. More recently, in 2025, Ohio enacted HB 15, ending coal subsidies tied to HB 6 and modernizing permitting timelines. While not nuclear-specific, the reform could indirectly benefit advanced nuclear projects by leveling the market, as coal has historically been a central economic driver, both with respect to production and consumption.

Oklahoma has no nuclear power plants and has not advanced legislation to support new nuclear deployment. The state’s electricity generation is dominated by natural gas and wind.
Nuclear has not been part of Oklahoma’s energy policy framework, and public debate and policymaking around energy remain focused on natural gas as a baseload resource and wind as a fast-growing clean energy contributor. The state’s regulatory and legislative landscape has prioritized expanding transmission and natural gas infrastructure, rather than exploring nuclear options.
On December 3rd, 2025, the DOE’s National Nuclear Security Administration (NNSA) announced that it had removed all cesium-137 irradiators in the state, as part of the Cesium Irradiator Replacement Project, which aims to eliminate radiological risks across the country. This achievement made Oklahoma the 12th U.S. state/territory to be free of cesium irradiation.

Oregon is somewhat of a paradox in U.S. nuclear energy: a state with some of the strongest restrictions on deployment but also a global leader in nuclear innovation. A 1980 voter-approved ballot measure requires a statewide referendum before any new nuclear plant can be built (ORS § 469.595), and Oregon’s only reactor, the Trojan Nuclear Plant, was permanently closed in 1993. As a result, the state has no nuclear generation in its portfolio and no immediate pathway for siting new plants.
Yet Oregon is also home to NuScale Power, developer of the first small modular reactor design approved by the Nuclear Regulatory Commission, and to Oregon State University’s nationally recognized nuclear engineering program, which houses the first NuScale control room simulator.

Rhode Island has no nuclear power plants and is one of the few U.S. states with no legislative or regulatory framework to pursue nuclear energy. Its small size, dense population, and reliance on natural gas and imported electricity have kept nuclear absent from state energy planning.
State policy has instead emphasized offshore wind, solar, and efficiency, with major initiatives aimed at positioning Rhode Island as a hub for offshore wind development in the Northeast. Nuclear has not been part of legislative debate in recent years, nor has the state introduced proposals for advanced nuclear technologies.

South Carolina is among the most nuclear-reliant states in the U.S., generating more than half of its electricity from nuclear power through four operating plants (Catawba, McGuire, Oconee, and V.C. Summer). The state also hosts the Savannah River Site, a major federal facility for nuclear materials management and research.
South Carolina was once at the center of new-build efforts with the V.C. Summer Units 2 and 3 project, which was abandoned in 2017 after billions in cost overruns and delays. Since then, state policymakers have been cautious on new reactor construction, but nuclear remains foundational to the state’s energy mix. Recent discussions in South Carolina have centered on workforce development, SMR potential, and federal partnerships at Savannah River, rather than direct state-led legislation to expand capacity.

South Dakota has no operating nuclear power plants and no history of commercial nuclear generation. The state’s electricity mix is dominated by hydropower, wind, and coal, with renewable generation making up more than half of total output.
Nuclear power has not featured prominently in South Dakota’s energy policy, and there is no legislative framework in place for advanced nuclear development. While national conversations around coal-to-nuclear transitions have referenced states with significant coal fleets, South Dakota has not advanced proposals to repurpose sites for nuclear.

Tennessee Gov. Bill Lee proposed allocating more than $90 million to help subsidize a Tennessee Valley Authority project to install several small reactors, boost research and attract nuclear tech firms. As a long-time proponent of the TVA’s nuclear project, Lee also launched Tennessee’s Nuclear Energy Fund in 2023, designed to attract a supply chain, including a multibillion-dollar uranium enrichment plant billed as the state’s biggest-ever industrial investment.

Texas prides itself on being the “energy capital of the world”. It is setting itself up to become the “epicenter” for deployment of advanced nuclear and has taken some impressive steps to achieve this goal. In the aftermath of Winter Storm Uri, which resulted in extended power outages that caused many cold-related fatalities, an industry group got together to form the Texas Nuclear Alliance, dedicated to the advancement of nuclear technology in Texas and a mission to make Texas the “Nuclear Capital of the World.” TNA’s underlying premise was that, to meet the need for low-carbon and reliable energy, Texas could not afford to turn its back on “clean, safe, reliable and secure” nuclear energy.
By late 2023, Texas Governor Greg Abbott directed the Texas Public Utility Commission to establish a working group to study advanced nuclear. A year later, in November 2024, the Governor and the PUCT announced the release of the Texas Advanced Nuclear Reactor Working Group’s final report on Texas’ plan to build a world-leading advanced nuclear power industry. The report’s multiple goals sought to enhance electric reliability and energy security, promote economic development, and unleash new opportunities for the growing Texas workforce. In commenting on the PUC’s report, Governor Abbott said:
“Texas is the energy capital of the world, and we are ready to be No. 1 in advanced nuclear power. By utilizing advanced nuclear energy, Texas will enhance the reliability of the state grid and provide affordable, dispatchable power to Texans across the state. As we build an advanced nuclear industry in our great state, we will ensure Texas remains a leader in energy and strengthen the Texas grid to meet the demands of our growing state.”
If you click on the report image on the right, it takes you directly to the report package, which is a thing of beauty. The Executive Summary finds five key benefits to making Texas the epicenter of advanced nuclear in the U.S.: 1) Enhance energy security; 2) Improve grid reliability; 3) Expand economic development opportunities; 4) Capture first-in-nation advantages that bring jobs, revenue and industrial growth; and 5) Capture international trade opportunities as the world works to triple the amount of nuclear available by 2050.
The comprehensive legislative package, including HB 14, SB 1535, and SB 1061, became fully effective on September 1, 2025, officially establishing the Texas Advanced Nuclear Energy Office (TANEO) and the Texas Advanced Nuclear Innovation Fund. This was released around the same time as other major agreements took place: Texas-based developer Fermi America signed a Memorandum of Understanding (MOU) with Korea Hydro & Nuclear Power (KHNP) and Samsung C&T Corporation for the Korean companies to participate in the construction of Fermi's planned 11-GW advanced energy complex near Amarillo.
How will Texas take this lead? By doing what Texas does best: cutting “red tape” and establishing major “incentives” to “attract investments,” accelerate advanced nuclear deployments, and overcome regulatory hurdles. It’s a very good plan...and far exceeds efforts by any other state to attract advanced nuclear development to itself.
Best of all, Texas isn’t merely posturing. The Texas Nuclear Alliance has partnered with the Texas A&M University System (TAMUS, which boasts eleven universities, eight agencies and an enormous 2100 acre parcel of land called the Rellis Campus devoted to supporting technology innovation) and announced that they have selected four advanced nuclear ventures to build their own advanced reactor at Texas A&M. These companies, called TNA Founding Members, include: Kairos Power, Natura Resources, Terrestrial Energy and Aalo Atomics. These companies responded to an RFP in the summer of 2024 to bring their designs to the Rellis campus and were accepted. While there are unknowns about what this selection means for these companies, solving the siting issue can provide a significant advantage in the highly competitive race to be the first to deploy.

Utah Gov. Spencer Cox's "Operation Gigawatt" to double the state's electricity generation is driving rapid advancements in nuclear deployment. The state is fulfilling its goal to become the "nation's nuclear hub" by actively attracting reactor developers. In September 2025, Valar Atomics broke ground on its Ward 250 test reactor at the Utah San Rafael Energy Lab (USREL). Further demonstrating momentum, a major partnership was announced in November 2025 with Brigham City, Hi Tech Solutions, and Holtec International to create a "full-scale nuclear energy ecosystem" based in Brigham City. This project, which includes the deployment of Holtec's SMR-300, has secured over $750 million in private investment and is expected to create hundreds of long-term jobs. These physical demonstration projects, alongside the earlier MOU with TerraPower and Flagship and the creation of an Investment Fund, cement Utah's stance as an aggressively pro-nuclear, deployment-oriented state.

Vermont currently has no operating nuclear power plants following the closure of the Vermont Yankee facility in 2014, which used to account for 70%–80% of the state’s net generation.
Overall, the state’s energy policy remains notably restrictive on nuclear since the passing of H.127 (30 V.S.A. § 248) in 1975 which requires explicit approval from the General Assembly for new nuclear power plant construction before the state's Public Service Board can issue a "certificate of public good" for any new nuclear plant. This granted the legislature a direct veto over new nuclear facilities.
However, the state is showing early signs of renewed interest in nuclear feasibility, particularly regarding advanced technologies. In 2025, lawmakers introduced H.287, proposing the formation of a Vermont Small Nuclear Consortium to conduct a feasibility study on reintroducing nuclear generation in the state. Governor Phil Scott, in addressing rising power demand driven in part by AI infrastructure, stated publicly that SMRs could serve as a short-term clean energy bridge.
Virginia’s recent pro-nuclear moves include state funding for an energy “career cluster” and a state-supported energy lab that help enable deployment of advanced nuclear reactors near former coal mines. These efforts are designed to attract workers, jobs and investments by companies in the growing advanced nuclear sector, which is poised to begin building SMRs at the country’s already shuttered and retiring coal plants. Dominion Energy issued a request for proposals for a possible small modular reactor deployment at its 1,892-MW North Anna Power Station and subsequently announced a memorandum of understanding with Amazon to support the Virginia project. Virginia joined the National Association of State Energy Officials’ Advanced Nuclear First Mover Initiative, or ANFMI, a regional initiative.

Washington has begun to integrate advanced nuclear into its broader decarbonization agenda. In 2023, the Legislature amended the state’s clean energy strategy (SB 5129) to explicitly include advanced reactor technology, and although a companion bill (HB 1584) cleared the House by a wide margin, it failed in the Senate. Nonetheless, more recent proposals in 2025, including HB 1679 and HB 1249, would let utilities count nuclear toward clean energy mandates and create a state advisory commission to examine SMR siting, workforce needs, and financing. Both measures remain pending.
Outside the legislature, the most visible development has been Energy Northwest’s partnership with X-Energy to plan as many as 12 Xe-100 reactors at the Hanford site, with Amazon backing the project. Early work is underway, but deployment is targeted for the 2030s. Washington has therefore established a policy framework that acknowledges nuclear as part of its climate strategy while leaving concrete deployment to utility-led initiatives still in early planning stages.

Wyoming, seen as an “early mover,” is one state that began laying the groundwork to attract and build next-generation nuclear prior to 2020, when Republican Gov. Mark Gordon signed a bill forbidding coal plants to close but allowing small modular reactor capacity to replace the coal generation capacity. Subsequent legislation in 2022 and 2023 provided regulatory streamlining for advanced reactor deployment and authorized the state to match private funds up to $150 million. These actions helped the state win over TerraPower, the advanced nuclear venture owned by Bill Gates, which is now building infrastructure for what may be the first advanced nuclear power plant near the site of a retiring coal-fired power plant in Kemmerer, Wyoming. This project is advancing rapidly through the federal process: the NRC completed the Environmental Impact Statement (EIS) in October 2025 and issued the Final Safety Review in December 2025, marking the first FSE for an advanced reactor completed with a fully risk-informed approach. It helped Wyoming a lot that Bill Gates was then close friends with Warren Buffett, whose Wyoming-based company, PacifiCorp, owns many struggling coal plants and so found a site they were willing to let TerraPower use. Wyoming joined the National Association of State Energy Officials’ Advanced Nuclear First Mover Initiative, or ANFMI, to develop supportive policies, coordinate with private stakeholders, and work toward unique procurement and financing options for nuclear energy projects.
