Nuclear power is staging an unexpected comeback, driven by artificial intelligence's insatiable appetite for electricity. The U.S. Department of Energy has closed a $1.9 billion loan commitment to restart Iowa's Duane Arnold nuclear plant, while tech giants like Google, Microsoft, and Meta are signing long-term power agreements and investing in new reactor development. This convergence of government support, corporate demand, and Wall Street investment is reshaping the nuclear industry after decades of decline.

Why Is AI Suddenly Making Nuclear Power Attractive Again?

The answer lies in raw electricity demand. Modern artificial intelligence systems, particularly large language models and data centers that train them, consume enormous amounts of power continuously. Goldman Sachs forecasted that global power demand from data centers alone could increase by 165 percent by 2030. A single advanced data center can require as much as 1 gigawatt of power, equivalent to the electricity consumption of an entire city. Unlike renewable energy sources that depend on weather conditions, nuclear provides reliable baseload power 24 hours a day, making it uniquely attractive to companies that cannot afford service interruptions.

The Duane Arnold plant near Cedar Rapids, Iowa, exemplifies this trend. The 615-megawatt facility was shut down in 2020 after a severe windstorm damaged one of its cooling towers, but the economics have shifted dramatically. NextEra Energy, the plant's owner, secured the federal loan and announced a 25-year power purchase agreement with Google to help finance the restart. The Nuclear Regulatory Commission (NRC) shared progress on the restart at a public hearing, with officials indicating that licensing actions will be issued before January 2028 and the plant could return to operation in early 2029.

What Does the Nuclear IPO Wave Tell Us About Market Confidence?

Wall Street is signaling serious conviction in nuclear's future. Holtec Nuclear, a company that manufactures nuclear components, handles spent fuel, and is developing small modular reactors (SMRs), is scheduled to list on Nasdaq on September 18, 2026, with an IPO valuation reaching up to $10.2 billion. The company is not simply a speculative bet on future reactors; it already generates revenue from existing operations and is attempting to restart the 800-megawatt Palisades plant in Michigan while developing its own SMR technology.

Holtec joins a growing wave of nuclear companies testing public market appetite. X-energy and Standard Nuclear are also pursuing listings, while Westinghouse is exploring a public offering. However, investment strategists caution that the enthusiasm must be tempered by economic reality. The construction cost of new reactors remains a critical challenge. Recent U.S. projects like Vogtle Units 3 and 4 cost approximately $15,000 per kilowatt of capacity, while the Barakah nuclear plant in the United Arab Emirates, built using repeatable South Korean designs, achieved roughly $4,400 per kilowatt. Holtec targets $7,500 to $8,500 per kilowatt for future dual-unit SMR projects in high-cost U.S. markets, but delivering on that promise will determine whether the IPO wave represents genuine industrial transformation or speculative excess.

How Are Tech Companies and the Government Coordinating on Nuclear Expansion?

The partnership between private industry and government has become the engine driving nuclear revival. Beyond Google's 25-year agreement with NextEra, Microsoft and Constellation Energy are united on an agreement to restart Unit 1 at the retired Three Mile Island plant in Pennsylvania. Meta and Amazon are committing to future development of small modular reactors, which are smaller, standardized designs intended to reduce construction complexity and cost.

The federal government is actively facilitating these partnerships. The Department of Energy's Office of Energy Dominance Financing, created during the second Trump Administration, is leading loan allocations to nuclear projects. Deputy Secretary of Energy James P. Danly stated that restarting Duane Arnold would "return 615 megawatts of reliable baseload generation" and "drive down electricity costs, while supporting thousands of American jobs". The Duane Arnold restart alone is projected to create 1,500 construction jobs and approximately 450 permanent operational positions.

What Regulatory Milestones Must Be Achieved Before Reactors Can Restart?

The NRC has established a detailed timeline for Duane Arnold's return to service. The licensing process requires several key amendments to transition the plant from decommissioning status to operational status. These include restoring conditions in the operating license and technical specifications, addressing emergency preparedness requirements, and updating the facility's security plan. The NRC's Division of Operating Reactor Licensing plans to issue a bundle of these licensing actions before January 2028, with a public notice scheduled for April 22.

The public will have 30 days to comment on the amendment requests and 60 days to request a public hearing. Inspections are ongoing at the facility, with key areas being assessed including pumps, valves, piping, reactor vessel structural integrity, and radiation protection systems. Site inspections are scheduled for 2026 and continuing into 2027, with two inspection reports already available for public review.

Steps to Understanding Nuclear's Role in AI's Energy Future

• Distinguish asset types: Investors and policymakers must separate existing cash-generating nuclear assets from businesses dependent on future reactor deployment. Companies like Constellation Energy operate existing plants, while developers like Oklo depend on permits and construction that have not yet begun.
• Monitor construction costs: The critical metric is dollars per kilowatt actually delivered, not megawatts promised. Falling construction costs and repeatable projects matter more than ambitious capacity announcements. The gap between U.S. costs ($15,000 per kilowatt) and international benchmarks ($4,400 per kilowatt) reveals the importance of standardized design and supply chain stability.
• Track regulatory progress: Binding power agreements, completed environmental assessments, and regulatory approvals provide stronger evidence of viability than non-binding plans. The Duane Arnold restart demonstrates how federal loan support, corporate power purchase agreements, and NRC licensing milestones create a credible pathway to operation.
• Evaluate execution risk: AI demand for electricity is real, but natural gas, renewables, batteries, and grid upgrades can arrive faster than new reactors. The winners will be companies that convert demand into signed contracts, permits, and completed construction milestones.

What Economic Benefits Are Communities Expecting?

Local stakeholders are enthusiastic about nuclear's return. Barbra Solberg, senior vice president of public policy and partnerships at the Cedar Rapids Metro Economic Alliance, spoke in support of the Duane Arnold restart at the NRC public hearing, stating that "the economic impact of the restart will be immense". NextEra cited a 2025 study projecting the restart would generate more than $9 billion in economic benefits for the Cedar Rapids area and Iowa over 25 years. Solberg added that the restart "signals an investment-friendly environment that will drive new opportunities and developments to our areas and ensure the continued growth of the Cedar Rapids area".

Beyond Duane Arnold, the broader nuclear expansion is creating opportunities across the supply chain. Dow Chemical has contracted X-energy to deliver small modular reactor technology to provide carbon-free electricity for a chemicals facility along the Texas coast, with the NRC currently studying the permit application. These projects demonstrate that nuclear's revival extends beyond data centers to industrial manufacturing and regional economic development.

What Are the Key Risks That Could Derail Nuclear's Momentum?

Despite the optimism, significant challenges remain. Rising cost-per-kilowatt estimates, delayed regulatory milestones, or repeated requests for additional government funding would be early warning signs that the nuclear revival is losing steam. Holtec's IPO structure also presents a governance concern; founder-linked entities are expected to retain roughly 99 percent of voting power over director elections after the listing, leaving public shareholders with limited influence.

The fundamental tension is that electricity demand is real, but execution will determine who gets paid for solving it. AI servers can be built much faster than reactors, meaning that if construction timelines slip or costs remain elevated, data center operators may turn to alternative power sources. The nuclear industry's success depends not on Wall Street enthusiasm or government support alone, but on delivering standardized, cost-effective reactors on schedule.
