The Slow Bloom of Modular Dreams

by

Nuclear Reactor Landscape

The year unfolds, and with it, a curious efflorescence in the realm of small modular reactors. NuScale Power and Oklo Inc., names whispered with a blend of hope and apprehension, have experienced a surge—a veritable spring thaw—in valuation. Since the turning of the year, NuScale has climbed, a vine seeking sunlight, by over 400 percent. Oklo, not to be outdone, has mirrored this ascent, rising nearly 600 percent. Yet, the market, a fickle garden, is not easily impressed by mere growth. A recent retreat—a gentle pruning, if you will—has tempered the initial exuberance.

One might ask, what accounts for this shift? The technology itself, a promise of decentralized, cleaner energy, remains, in the long view, a reasonable wager. But the market’s gaze, ever restless, has settled upon a more immediate concern: the ability of these enterprises to translate ambition into tangible revenue. To move from blueprints and simulations to a functioning reality is a labor akin to coaxing life from barren soil.

The challenge is not merely technical, but temporal. The initial optimism, a heady bloom, has begun to fade, revealing the long, patient years required for such endeavors to bear fruit. It is a lesson history repeatedly imparts: the most revolutionary seeds require the most diligent tending, and even then, the harvest is never assured.

The Weight of Unfulfilled Promises

Reports from institutions like the Institute for Energy Economics & Financial Analysis have cautioned against premature rejoicing. The assessment is stark: these reactors, while promising in concept, remain too costly, too slow to deploy, and too fraught with risk to meaningfully address the urgent need for a transition away from fossil fuels within the next decade or so. It is a sobering reminder that innovation, however brilliant, is not immune to the constraints of economics and logistics.

The allure, of course, lies in the potential for economic competitiveness. Yet, the early experiences with existing small modular reactor projects suggest that this promise remains largely unfulfilled. The initial costs, like the roots of an ancient tree, run deep, and the projected savings have yet to materialize. The market, initially captivated by the vision, has begun to demand more than mere promises—it demands demonstrable results.

One observer, a co-author of the aforementioned report, notes with quiet resignation that the on-the-ground reality often diverges sharply from the proponents’ optimistic projections. The dream, it seems, is still some distance from becoming a tangible landscape.

In the preceding year, the market, caught in a wave of enthusiasm, largely ignored these cautionary voices. Shares of Oklo and NuScale surged, fueled by new partnerships and customer acquisitions. However, in recent months, a more sober assessment has taken hold. Both stocks have experienced a significant correction, a gentle descent from the heights of speculation. The question now is not whether these companies can attract investment, but whether they can translate those investments into sustainable revenue streams.

NuScale’s keystone project in Romania, once slated for completion by 2030, is now projected to begin operation in 2033. This delay, coupled with growing concerns about execution risks and capital requirements, has prompted some analysts to downgrade the stock. Oklo’s pipeline has also come under scrutiny, particularly in light of substantial stock sales by its CEO and CFO in recent months—a quiet exodus that speaks volumes to those who pay attention.

A Long Winter, or the Promise of Spring?

Despite the recent correction, shares of both NuScale and Oklo remain elevated compared to their recent past. Oklo, for instance, is still up roughly 180 percent since the start of the year. However, their total market capitalization remains modest—a mere $10 billion for Oklo, and just over $4 billion for NuScale—considering the potential to reshape the global energy paradigm. These figures suggest a lingering uncertainty, a hesitant acknowledgment of the inherent risks.

These low valuations reflect two stark realities. First, there is no guarantee that these technologies will ever be deployed at scale. Proving the economic viability of a real-world deployment remains a distant prospect. And until that happens, demand will remain muted, a faint echo in the vastness of the market. Second, both Oklo and NuScale will require substantial additional capital to not only survive but to deliver on their contractual obligations. This will inevitably lead to further share dilution, a spreading of resources that may diminish the value of each individual holding.

I remain cautiously optimistic about the long-term prospects of small modular reactor technology. However, any investment thesis must be predicated on a holding period of a decade or more. Unless one is willing to embrace a long-term perspective, to patiently nurture these seeds through the inevitable winters, it is perhaps wiser to view these stocks as lottery tickets—intriguing, but ultimately opaque in their potential outcome.
