The Nuclear Renaissance: Why Nuclear Energy is Making a Comeback

by

As a seasoned energy analyst with over two decades of experience in the industry, I find myself intrigued by the renewed interest in small modular reactors (SMRs). Having witnessed the ebb and flow of various energy technologies throughout my career, I can attest that the potential benefits of SMRs are indeed compelling. The promise of cost-effective, flexible, and adaptable nuclear power is enticing, especially when we consider the growing energy demands of tech companies like Amazon.

This revival is not just altering the shape of the energy sector but also influencing how tech titans such as Microsoft, Google, and Amazon are supplying energy for their expanding data centers. The move to restart Pennsylvania’s dormant Three Mile Island nuclear plant symbolizes this change, indicating a broader inclination towards nuclear power as a practical, carbon-free energy option.

The Three Mile Island nuclear power facility, notorious for the 1979 incident that caused the most severe nuclear accident in U.S. history, is preparing to resume operations following a five-year break. Constellation Energy, the plant’s owner, has signed a long-term energy supply contract with Microsoft, lasting twenty years, to power its AI-focused data centers. Although Unit 2, which experienced the historic meltdown, remains shut down, efforts are being made to reactivate Unit 1, which was idled in 2019 due to financial concerns.

The working cooling towers of Exelon Generation Unit 1 in the foreground are emitting water vapor. The dormant cooling towers are from Unit 2, which was permanently damaged in the 1979 accident.

According to the recent deal, Unit 1 is set to add an extra 835 megawatts of power to Pennsylvania’s energy network. This expansion is projected to generate around 3,400 jobs and potentially boost the state’s economy by approximately $16 billion. In a related development, Constellation has chosen to rename the site as the Crane Clean Energy Center, in recognition of its former CEO, Chris Crane. Joe Dominguez, the current CEO of Constellation, emphasized the plant’s exceptional safety record before its shutdown and expressed confidence about its new purpose. As he put it, “Before it was closed due to unfavorable economics, this plant was one of the safest and most dependable nuclear plants on the grid.

Restoring the reactor is no small feat. Significant upgrades are required, including work on the turbine, generator, transformer, and cooling systems. The U.S. Nuclear Regulatory Commission must approve the plant’s restart, with a tentative go-live date set for 2028. Constellation hopes to secure licenses for operations through at least 2054, signaling a long-term commitment to nuclear energy.

Tech Giants Fueling the Nuclear Surge

Microsoft’s recent action is not a solitary event but rather a reflection of a broader pattern among tech titans, who are increasingly resorting to nuclear power to cater to their enormous energy demands. Both Google and Amazon have revealed partnerships involving Small Modular Reactors (SMRs) for their data centers. Google intends to draw power from reactors engineered by Kairos Power, while Amazon has put money into X-energy to develop reactors in collaboration with utilities based in Washington and Virginia.

The escalating trend in Big Tech’s usage of nuclear energy highlights their increasing dependence on it, as the drive for data centers to fuel artificial intelligence becomes more aggressive. Experts estimate that U.S. data centers could account for 8% of the country’s total energy production by 2030, with a projected rise in demand amounting to a staggering 160% compared to 2023 levels. As data centers consume more power, environmental worries increase. A recent assessment indicates that the carbon emissions from data centers operated by Microsoft, Google, Meta, and Apple could be as much as six times higher than the officially reported figures.

Nuclear power provides tech firms with an attractive advantage: it offers consistent, 24/7 power without any carbon emissions. Although these businesses are pouring resources into renewable energies such as wind and solar, the unpredictability and intermittency of these alternatives make nuclear a tempting choice. Amazon highlights nuclear’s lengthy history of dependable, emission-free energy and its potential for expansion, saying, “Nuclear power is an essential component – it can be rapidly scaled up and has demonstrated a proven record of providing reliable, safe carbon-free energy over several decades.

During a recent discussion, Donald Trump emphasized the possibility of nuclear energy strengthening America’s power resources, especially considering the increasing energy needs due to advancements in artificial intelligence, with Shawn Ryan – a former Navy SEAL and CIA contractor.

Trump stated, “AI requires a considerable amount of electricity compared to what we currently use. In fact, it’s estimated that we would need twice as much energy as we produce today in that sector alone if we aim to be leaders.

The Appeal and Challenges of SMRs

Small Modular Reactors (SMRs) are a promising advancement in nuclear energy technology. The Department of Energy (DOE) considers SMRs as potential cost-efficient and adaptable solutions, which could be less expensive, simpler to construct, and more versatile regarding placement. Energy Secretary Jennifer Granholm has expressed her backing, attending an event at Amazon’s Virginia headquarters to endorse this initiative.

Despite SMRs presenting promising opportunities, they encounter substantial challenges. These reactors are yet to receive approval from the Nuclear Regulatory Commission, which might push their realization to 2028 or even beyond. Additionally, handling hazardous waste from multiple sites poses a challenge. Public resistance and rigorous review could potentially slow down or halt these projects further.

Why Nuclear Energy is Making a Comeback

The revival of nuclear energy is due to several interconnected reasons. Initially, the increasing energy needs of tech corporations, fueled by rapid advancements in AI and data processing, demand a reliable and substantial power source. At present, while renewable energies are crucial for our sustainable future, they struggle to provide the necessary consistency and capacity to independently fulfill these intense demands.

In second place, the urgent priority to lessen carbon emissions coincides perfectly with nuclear power’s zero-emission operation. As the gravity of climate change grows, nuclear energy becomes an increasingly viable option compared to fossil fuels. The Intergovernmental Panel on Climate Change (IPCC) acknowledges nuclear energy as a crucial element in the collection of strategies for combating global warming.

Thirdly, Progress in nuclear technology, specifically Small Modular Reactors (SMRs), brings the potential for safer, more efficient power plants that can be adapted to multiple environments. These advancements might help assuage public concerns about nuclear energy, primarily those related to safety and waste disposal.

To conclude, governmental assistance is vital. The Biden administration’s endorsement of nuclear projects offers not just monetary incentives but also sparks regulatory progress. By advocating for a diverse energy approach termed “all of the above,” the government is preparing the ground for nuclear power to regain its place in the mainstream energy market.

Though reviving nuclear energy may tackle some urgent problems, it’s important to note that it doesn’t come without debate. The past nuclear accidents, such as Three Mile Island, Chernobyl, and Fukushima, have left a lasting impression on public opinion due to safety concerns, waste management difficulties, and the substantial costs linked with nuclear projects. These aspects cannot be disregarded.

While it’s important not to discount nuclear energy entirely, given the pressing issue of climate change, we should consider all possible solutions to cut down on greenhouse gas emissions. Nuclear power, with its ability to generate large amounts of consistent energy, offers a unique potential to work alongside renewable sources. It can serve as a transitional technology, helping us move towards a completely sustainable energy system.

Tech titans might serve as the spark that propels us past the “nuclear innovation valley of death.” With their vast financial assets and personal stake in ensuring a dependable energy source, they could expedite the creation and implementation of sophisticated nuclear technologies. As Kelly-Detwiler stated, “The power requirements of tech giants could speed up this emerging technology, which is beneficial because modular nuclear technology may be what the industry and world needs to proceed with decarbonization efforts.

Yet, we must proceed with caution. Rigorous safety standards, transparent regulatory processes, and public engagement are essential to ensure that the resurgence of nuclear energy does not repeat past mistakes. Investment in research and development should also focus on solving the long-term waste disposal problem, perhaps through technologies like nuclear recycling or advanced reactors that can utilize spent fuel.
