US Nuclear Plant Revival: Data Centers Drive $4.4B DOE Restart Loans

• The U.S. is attempting to restart three decommissioned nuclear plants, an unprecedented move for commercial reactors.
• The Department of Energy is providing up to $4.4 billion in loans to revive the Palisades, Crane Clean Energy Center, and Duane Arnold facilities.
• These plants will collectively restore 2.25 gigawatts of electricity, largely to meet demand from data centers.
• Two of the plants have contracts with "Big Tech" companies willing to pay a premium for carbon-free energy.
• Experts highlight both the relative speed of restarting compared to new builds and significant safety and regulatory challenges.

The United States has embarked on a novel initiative to bring three previously decommissioned nuclear power facilities back online, marking the first known instance of commercial reactors resuming operation after entering the decommissioning phase.

The United States has embarked on a novel initiative to bring three previously decommissioned nuclear power facilities back online, marking the first known instance of commercial reactors resuming operation after entering the decommissioning phase. This ambitious undertaking is driven by a surging national demand for electricity, significantly fueled by the proliferation of large-scale data centers. The Department of Energy (DOE) is spearheading this effort, committing substantial financial backing through loans totaling up to $4.4 billion to facilitate the restart of these plants.

The three facilities targeted for revival are the Palisades Power Plant in Michigan, the Crane Clean Energy Center located on Pennsylvania’s Three Mile Island, and the Duane Arnold Energy Center in Iowa. Collectively, these plants are projected to restore 2.25 gigawatts of electrical capacity to the grid, an output sufficient to power approximately 2 million homes and businesses. This federal push also aligns with broader administration goals, with the Biden-Harris administration actively promoting nuclear power as a critical energy source for artificial intelligence and manufacturing sectors, alongside providing billions in funding for upgrades to existing operational nuclear facilities.

While some nuclear reactors have successfully resumed operations following extended outages, the current effort to restart facilities that had already begun decommissioning presents a unique set of challenges. Nuclear engineering expert Todd Allen notes that while restarting a reactor offers a relatively swift method to generate significant electricity and is more cost-effective than constructing a new, large-scale plant, the process is far from simple. He likens it to reactivating a car that has been idle for years, emphasizing the need for a valid operating license and ensuring all components are fully functional. For a nuclear plant, this translates into a complex array of tasks, including re-engaging and re-training nuclear workers, verifying the operational integrity of all systems, updating maintenance protocols, securing adequate fuel supplies, and obtaining the necessary regulatory approvals to reinstate their operating licenses. Allen describes this as "a lot to keep track of, but it's relatively straightforward."

However, concerns regarding safety and the allocation of taxpayer funds have been raised. Edwin Lyman, director of nuclear power safety at the Union of Concerned Scientists, contends that the substantial public investment should be primarily directed towards mitigating potential safety risks. He highlights that most U.S. nuclear plants, constructed between 1970 and 1990, were engineered to withstand natural disasters prevalent during that period. With climate change now contributing to more frequent and severe extreme weather events, Lyman questions the adequacy of existing designs. He suggests that while it is theoretically possible to restore these plants to a safe, operable condition by establishing stringent safety standards and committing the requisite financial resources, he believes this level of commitment "is not happening at this point."

The decision to revive these nuclear assets marks a significant shift from the circumstances that led to their initial closures. All three plants ceased operations before their licenses expired, primarily because the electricity they generated was deemed too expensive at the time. This economic landscape has dramatically changed, driven by the escalating demand for reliable, carbon-free energy, particularly from the rapidly expanding data center industry. Two of the plants slated for revival have already secured contracts with major technology companies, which are prepared to pay a premium for substantial quantities of clean energy to power their data centers.

This renewed interest underscores nuclear power's appeal as a zero-carbon energy source, aligning with both environmental goals and the commercial needs of energy-intensive industries. For instance, the Duane Arnold Energy Center in Iowa, which commenced operations in 1975, was originally scheduled for permanent closure in October 2020. It ultimately shut down prematurely in August 2020 after sustaining damage from a powerful storm known as a derecho. Its replacement with cheaper energy alternatives, such as wind power, was projected to save Iowa customers $300 million in energy costs. Despite this history, its potential for carbon-free generation now positions it as a valuable asset in the current energy market, with NextEra Energy owning the facility. The World Nuclear Association supports the celebration of restarting reactors, though it maintains that preventing their premature closure would be the optimal approach.

Lawyers advising energy companies, data center operators, or investors in the power sector should closely monitor the regulatory processes, safety reviews, and contractual frameworks emerging from the unprecedented federal initiative to restart decommissioned nuclear plants. This development presents both significant compliance challenges related to licensing and safety upgrades, and potential transactional opportunities for securing carbon-free energy or participating in federally-backed energy projects.
