NuScale’s Selloff Highlights the Gap Between Certification and Orders

A sharp selloff across nuclear-related stocks exposed an important divide inside the theme. NuScale Power and Oklo depend heavily on future reactor deployments, while Centrus Energy already sells enriched uranium. When enthusiasm cools, companies with distant revenue tend to fall further.

NuScale has a genuine regulatory advantage. Its uprated 77-megawatt module received a standard design approval from the U.S. Nuclear Regulatory Commission in 2025. That approval reduces one category of technical risk, but it does not create a customer contract, construction financing or a completed plant.

The company’s two largest commercial pathways remain unfinished. ENTRA1 Energy continues discussions with the Tennessee Valley Authority over a potential power-purchase agreement for a large deployment program. In Romania, RoPower is advancing conditions for a six-module project at Doicești. NuScale’s second-quarter release described both efforts as progressing, but neither is the same as a binding order with a funded construction schedule.

That distinction matters because NuScale’s engineering revenue fell after earlier work on the Romanian project ended. The company still faces cash burn while it waits for projects to move from studies and agreements into commitments.

Oklo has a similar timing problem. Its first commercial power remains a future event, so valuation depends heavily on licensing, financing and construction milestones. Centrus is different: it already participates in the nuclear fuel chain and earns revenue from enrichment-related activity. Its shares can still move with the sector, but the operating evidence is more immediate.

The broad demand case for nuclear power remains intact. Data centers, electrification and energy-security concerns are increasing interest in reliable low-carbon generation. Yet strong demand for electricity does not guarantee that a specific reactor design will be ordered on economic terms.

For NuScale investors, the decisive catalyst is a binding commercial agreement that specifies capacity, pricing, financing and timing. Until then, certification should be viewed as necessary progress rather than proof of commercialization. The selloff is a reminder that a thematic tailwind cannot erase project risk.
