How tech giants’ nuclear shift may reshape the energy landscape

As electricity demand surges, the challenges of relying on fossil fuels—environmental, economic, and geopolitical—are clear. Zero-carbon alternatives such as solar or wind hold promise, but face significant limitations, including intermittency, geographic incompatibility, and land use requirements. Nuclear, by contrast, offers clean, consistent energy capable of serving high-demand facilities like data centers or contributing to the grid as baseload. Nuclear has a higher power density than other technologies, making it a prime candidate to meet demand growth particularly in areas with limited land availability.

Nuclear's low variable costs and 18-24 month refueling cycles support predictable pricing and insulate it from broader shocks - especially compared to natural gas prices, which are very sensitive to geopolitics, or renewables, which depend on weather^4,5. This makes nuclear an important tool for building a resilient, predictable, and reliable energy system.

Diversified energy supply is vital to national security. While the U.S. once led reactor development, it has built only three since 2000, compared to 52 in China and 13 in Russia. This erosion of U.S. leadership carries far-reaching implications, from control over uranium supplies to the establishment of regulatory standards and nonproliferation efforts. Reclaiming leadership in nuclear power is not only an energy imperative but a national security priority⁶.

To spur a nuclear renaissance and meet growing demand, we recommend a combination of short-term and long-term actions.

In the short term, with SMRs not expected to be operational until 2029, nuclear gains can be achieved by improving the nation’s operational, large-scale reactors. This approach has been supported by the Biden administration, which prioritized extending the lifespan of existing facilities, increasing rated power generation, and, in select cases, restarting prematurely decommissioned plants. These efforts seemingly align with the Trump administration's stated goals of “modernizing the Nuclear Regulatory Commission, working to keep existing power plants open, and investing in innovative SMRs.”

Gaining the support of regulators is crucial, as demonstrated by the recent 2-1 FERC decision, which rejected the expansion of behind-the-meter co-location power from the Susquehanna Nuclear facility to an on-site Amazon data center as more information was required.⁹ Additionally, today data center providers are turning to natural gas energy solutions due to their short build times relative to long nuclear construction projects. Advocating for regulatory clarity – and addressing bipartisan concerns around energy affordability – will provide a more streamlined path for nuclear construction and investment security for further nuclear development.

We believe a three-pronged approach is necessary for a robust and long-term nuclear energy industry: regulatory support, innovation and technology partnerships, and cost reduction strategies.

Striking the right balance between safety and efficiency is key to accelerating nuclear energy deployment. While the U.S. Department of Energy’s Idaho National Laboratory has identified ways to potentially cut reactor licensing and approval times in half, accelerated approval processes cannot overlook the critical issue of spent nuclear fuel management¹⁰. With fuel still stored at plants across the country, a permanent solution requires Congressional action to confirm safety and sustainable progress. Modernizing nuclear regulatory processes, while maintaining rigorous safety standards, is essential for enabling faster and more efficient nuclear development.

Public support is equally vital. A recent report from the Texas Advanced Nuclear Reactor Working Group highlights bipartisan backing for nuclear power across demographics. It found that individuals who feel informed about nuclear energy are significantly more likely to support it, underscoring the need for targeted information campaigns to build public confidence in nuclear safety and reliability¹¹.

Addressing siting challenges and interconnection delays is the third major regulatory priority for scaling up nuclear deployment. SMRs offer two major advantages: their smaller footprint enables construction in areas too restrictive for traditional nuclear plants—an Oak Ridge National Laboratory study found nearly 27% of U.S. land could host an SMR, double that for conventional reactors—and their ability to be deployed in behind-the-meter configurations helps bypass siting constraints and interconnection delays. Effective deployment will require a holistic approach that considers geography, grid access, energy market dynamics, and available tax incentives¹².

On the industry side, big tech companies are demonstrating demand for nuclear to power data centers. These include Google’s partnership with Kairos Power for 500MWs of power at a series of advanced reactor sites; Microsoft’s 20-year power purchase agreement with Constellation Energy to restart Three Mile Island Unit 1 (renamed as Crane Clean Energy Center); Amazon’s participation in X-energy’s $500 million Series C financing; and Meta’s 4GW nuclear RFP.

On the government side, continued support from the new administration of programs initiated under the Biden administration is critical to advancing nuclear energy's competitiveness. Key programs include the October 2024 SMR Program Engagement, which allocates $900 million to support first-mover teams, the Inflation Reduction Act (IRA) and Loan Program Office, which further improves nuclear’s competitiveness by offering tax credits and financing solutions¹³.

Robust cost reduction strategies are necessary to expand the nation’s nuclear footprint. The DOE anticipates that up to 65% savings between first iteration reactor construction and follow-on delivery would be possible as learning-by-doing, standardization, and build time reduction are embraced. Modulization and offsite construction can similarly increase component quality and thereby reduce on-site re-work.

Building durable supply chains remains an important lever to mitigate future cost pressures as the U.S. receives the majority of its uranium and enrichment services from abroad. In the past year, the U.S. initiated efforts to secure its nuclear energy supply chains with key allies and invested in domestic uranium mining and enrichment. Supporting efforts to reinforce the U.S. nuclear supply chain will enable future price stability.
