The tech sector has a massive, power-hungry problem called artificial intelligence, and the federal government thinks giant, old-school nuclear reactors are the only way to solve it.
The Trump administration just put up $17.5 billion in low-interest Department of Energy loans to back the construction of 10 massive new nuclear reactors. Seven utilities have already signed letters of intent to grab a piece of this financing. The goal is simple but incredibly aggressive: buy up the incredibly expensive, long-lead mechanical parts now so these plants can open up to three years faster.

Instead of waiting for unproven small modular reactors (SMRs) that are still years away from commercial reality, this move pivots straight back to gigawatt-scale conventional power. Specifically, the cash is tied to buying the massive AP1000 reactor equipment manufactured by Westinghouse Electric Co.
It is a high-stakes bet that directly confronts the realities of a strained American power grid. Observers at CNBC have shared their thoughts on this trend.
Shaving Years Off the Nuclear Timeline
Building a conventional nuclear plant in the US is notorious for taking forever. The Department of Energy is attempting to bypass this historical bottleneck by front-loading the money.
Usually, a utility waits until it has every final permit and an absolute green light on investment decisions before ordering core machinery. Under this new program, the $17.5 billion functions as conditional loans allowing companies to lock in heavy equipment—like reactor vessels, massive steam generators, and specialized coolant pumps—at fixed prices before the final paperwork is even finished.
By compressing the supply chain timeline, the administration claims it can shave up to three years off construction schedules. It also throws a financial lifeline to a domestic manufacturing base that has been mostly idle for decades.
The Shadow of Past Cost Overruns
You can't talk about large-scale Westinghouse AP1000 reactors without addressing the elephant in the room: Plant Vogtle in Georgia.
Vogtle Units 3 and 4 are the only traditional reactors completed in the US this century. They are engineering marvels, but they were also a financial disaster for the developers. The project ballooned from an initial $14 billion estimate to over $30 billion, landing years behind schedule and dragging its original builders into bankruptcy.
Because of that scar tissue, utilities have been terrified of big nuclear. The entire industry shifted its rhetoric toward small modular tech, pitching it as cheaper and easier to build. But small tech isn't ready to handle the immediate explosion of power demand coming from AI data centers right now.
By stepping in with billions in low-cost federal financing, the government is essentially trying to absorb the exact market risks that scare private capital away. If the fixed-price manufacturing strategy works, it proves Vogtle's delays were a learning curve, not an inherent flaw in big nuclear. If it fails, taxpayers are on the hook for another round of expensive delays.
The Hungry AI Data Center Demand
This sudden urge to revive heavy nuclear isn't happening in a vacuum. Tech giants are building data centers at a pace that standard wind, solar, and natural gas lines simply can't keep up with.
An executive order issued last year laid out a clear mandate: get 10 large conventional reactors under construction by 2030. Tech companies want clean, carbon-free energy, but more than anything, they want baseload power—electricity that stays on 24 hours a day, regardless of whether the sun is shining or the wind is blowing.
While a single large data center can require as much power as a small city, a traditional gigawatt-scale reactor can pump out enough electricity to power roughly 750,000 homes. Building 10 of them completely alters the capacity math for regional grids struggling to keep up with the computing boom.
Real Steps for Energy Investors and Utilities
The federal government is making it clear that big nuclear is back on the table, and the money is flowing. If you're managing utility portfolios or tracking energy infrastructure, here is where the immediate focus needs to shift.
- Track the Seven Utilities: Keep a close eye on upcoming regulatory filings. The seven utilities holding these letters of intent will have to go public to their state utility commissions soon to formalize these equipment orders.
- Monitor the Supply Chain Bottlenecks: Watch Westinghouse's main partners, Brookfield Asset Management and Canadian uranium producer Cameco Corp. The pressure is now entirely on their ability to scale up manufacturing for 10 units simultaneously without hitches.
- Evaluate Regional Grid Capacities: Focus on PJM Interconnection and the Southeast markets. These areas face the highest data center growth pressures and are the most logical geographic fits for large-scale AP1000 deployments.
