TVA Eyes Small Modular Reactors at Bellefonte Nuclear Site

A Stalled Plant Gets New Life

The Tennessee Valley Authority is moving quickly to revive the long-dormant Bellefonte Nuclear Plant in Alabama, this time as a home for advanced small modular reactors (SMRs) rather than the conventional reactors originally planned decades ago. TVA's interim CEO Mike Skaggs told attendees at a nuclear industry conference that the utility is engaged in fast-paced negotiations to bring SMR technology to the site, signaling that one of the nuclear industry's most notorious unfinished projects could finally find a purpose 1.

Bellefonte has long stood as a symbol of nuclear ambition outpacing execution — construction began in the 1970s but was never completed, leaving the site idle for decades. TVA's renewed interest reflects a broader shift across the power sector, where utilities are scrambling to secure new generation capacity to meet surging electricity demand, much of it driven by artificial intelligence data centers.

The AI-Driven Nuclear Rush

The Bellefonte move is part of a much larger pattern: power companies racing to lock in nuclear capacity as AI workloads strain the grid. Constellation Energy has taken a similar path, investing in Blue Energy in an effort to position itself at the front of the SMR race as data center operators seek reliable, carbon-free power to run energy-hungry computing clusters 2. The logic is straightforward — AI data centers require enormous, steady baseload power, and nuclear, particularly compact modular designs, is increasingly viewed as a faster and more flexible answer than traditional large-scale reactors.

That urgency is playing out at other sites as well. In New Jersey, plans to build an SMR-160 reactor at the Oyster Creek site have drawn scrutiny from environmentalists, underscoring that not every community is embracing the SMR push without pushback or questions about safety, waste, and siting near existing nuclear infrastructure 3.

Competing Technologies and a Growing Supply Chain

The SMR field itself remains competitive and unsettled. Investors are actively weighing which companies are best positioned to capitalize on the moment, with comparisons between NuScale Power and GE Vernova highlighting how different approaches to reactor design and manufacturing could shape which firms emerge as market leaders 4.

Behind the reactor developers, the fuel supply chain is also mobilizing. Centrus Energy's stock surged after it signed a uranium enrichment agreement with X-Energy to supply low-enriched and high-assay low-enriched uranium (HALEU) for X-Energy's Xe-100 reactors and TRISO-X fuel production, illustrating how enrichment capacity is becoming a critical bottleneck — and business opportunity — as SMR deployment accelerates 5.

Why It Matters

Taken together, these developments show an industry realigning around a new demand driver: AI infrastructure. TVA's Bellefonte plans, Constellation's investments, Oyster Creek's proposal, and the NuScale-GE Vernova rivalry all point to utilities and manufacturers positioning themselves for a wave of SMR construction, while Centrus's enrichment deal shows the fuel ecosystem racing to keep pace. Whether these projects can move from negotiation and investment to actual operating reactors within the timeframes AI companies expect remains the central question facing the sector.
