SMR Nuclear Push Grows Amid AI Power Demand, Investor Doubt

A Familiar Site Reconsidered

The former Oyster Creek nuclear plant site in New Jersey has resurfaced as a candidate for a new kind of nuclear facility, with interest expressed in building an SMR-160 small modular reactor there. Environmentalists have raised concerns about the proposal, echoing longstanding worries about siting nuclear infrastructure at a location with a complicated regulatory and safety history 1. While details on the current status remain limited, the renewed interest reflects a broader national trend: small modular reactors (SMRs) are increasingly being floated as a solution to surging electricity demand, particularly from artificial intelligence data centers.

The AI Power Crunch Driving Nuclear Interest

Across the country, the explosive growth of AI computing has strained power grids and pushed hyperscale technology companies to look beyond traditional fossil fuel and renewable sources. SMRs have been marketed as a compact, scalable option that could be deployed closer to data centers or industrial sites without the massive footprint of conventional reactors. This demand narrative has fueled investor enthusiasm for companies developing the technology, even though commercial-scale SMRs remain largely unproven and have yet to generate consistent revenue 4.

That enthusiasm has extended well beyond data centers. The Port of Long Beach, for instance, signed a deal to explore small offshore nuclear reactors to help power its operations and vessels, illustrating how industries with heavy, round-the-clock energy needs are exploring nuclear alternatives to decarbonize while meeting demand 3.

Investor Skepticism Meets Market Reality

Despite the hype, financial markets have shown a divided response. Short sellers have profited enormously from betting against SMR developers, reaping more than $2 billion over the past year from bearish positions on companies including NuScale Power, Nano Nuclear Energy, and Oklo 24. This suggests that while hyperscalers and industrial players have poured capital into the sector on the promise of future demand, skeptics view the technology as commercially immature, with reactor designs still years from widespread deployment and profitability.

Yet not all recent news has been negative for the sector. Oklo reported a significant technical milestone in its reactor development, a development framed as a positive signal for nuclear-focused exchange-traded funds and the broader investment case for SMRs 5. This contrast — short sellers cashing in on stock declines even as individual companies report technical progress — captures the volatility and uncertainty currently defining the small modular reactor market.

What It Means Going Forward

Taken together, the coverage illustrates a sector caught between long-term strategic promise and near-term financial turbulence. Local opposition, as seen at Oyster Creek, adds another layer of friction to deployment timelines, even as demand pressure from AI infrastructure and industrial users continues to grow. Whether SMRs can bridge the gap between speculative investment and reliable, revenue-generating power generation remains an open question that will shape both energy policy and financial markets in the years ahead.
