NuScale Power: First Safety-Grade SMR Fuel Pellets Produced, September 2026

NuScale and MillenniTEK have produced the first safety-grade fuel pellets for an NRC-approved SMR design, marking the transition from regulatory drawings to physical hardware — at a company carrying a roughly $4 billion market capitalization on trailing twelve-month sales of approximately $10.7 million.

On September 10, NuScale Power and manufacturing partner MillenniTEK announced the production of the first batch of safety-grade fuel pellets for NuScale's VOYGR small modular reactor — the only SMR design to have received Design Certification from the U.S. Nuclear Regulatory Commission. The safety-grade classification is not a marketing label: it denotes that the pellets were produced under the quality assurance standards governing nuclear safety systems, meaning they are eligible for installation in a licensed reactor. For a technology that has spent years accumulating regulatory approvals and partnership announcements, producing a tangible, certified piece of reactor hardware carries a different kind of evidential weight. Markets registered the shift a day early: NuScale's stock closed September 9 at $11.18, up 15.3% on the session, before retreating to $10.81 on September 10 — the same day as multiple SEC filings, including a quarterly 10-Q and two 8-K current reports, entered the public record.

The backdrop against which this milestone arrives is a company whose commercial reality remains far behind its regulatory accomplishment. NuScale disclosed Q2 2026 revenue of $75,000 — a figure that attracted widespread attention as emblematic of the gap between NRC approval and contract revenue. Motley Fool noted in August that the company's revenue had effectively fallen 99% year over year while its cash reserves grew by roughly $900 million, supported in part by a $750 million equity offering launched in late August. As of that same period, NuScale carried approximately a $4 billion market capitalization against trailing twelve-month sales of around $10.7 million, according to AOL's analysis from August 21 — a ratio that reflects investor positioning on future deployment rather than current earnings power. Slicast's compilation of SEC XBRL filings shows capital expenditure reaching $508,000 in FY2025, up 1,054.5% from $44,000 in FY2024, and climbing to $2 million in the quarter ended March 31, 2026. At 2% of its $31 million FY2025 revenue base, NuScale ranks last among the seven power companies tracked by Slicast on capex intensity — behind sector leaders Vistra and, on absolute expenditure, Constellation Energy. That ranking is a function of life stage, not capital discipline: the company is building a supply chain and an order book, not yet pouring concrete.

The fuel pellet announcement is one of several supply-chain moves in recent weeks that NuScale has layered on top of its commercial pipeline. In late August, the company disclosed a strategic alliance with Nuclearn and NPX to deploy nuclear-specific AI tools for advanced reactor program management. MarketScale reported separately that NuScale and Nucor Steel are in discussions about integrating SMR-generated power into industrial planning — a "always-on" baseload pitch aimed at heavy manufacturers whose energy costs are structurally exposed to grid volatility. The most consequential potential transaction remains the reported discussions with the Tennessee Valley Authority. Motley Fool cited NuScale's chief executive in August describing a potential 6-to-8 gigawatt TVA deployment as potentially the largest nuclear build-out in U.S. history, a framing that reflects both the scale of the opportunity and the distance between a conversation and a signed contract. The Curio-Framatome fuel-cycle partnership disclosed in August also drew analyst attention as a development that could deepen the qualified-fuel supply chain that the MillenniTEK pellet production now visibly extends.

The risk register is equally concrete. The history of U.S. nuclear construction is not encouraging: as AOL noted in August, the last domestic nuclear expansion saw 26 reactor applications and yielded two completions. NuScale's $750 million equity offering, while extending its operational runway, introduces dilution pressure that will intensify if signed commercial agreements do not materialize within a reasonable horizon. The company's Q2 earnings miss and near-zero revenue validate caution, and coverage from late August flagged growing community and regulatory resistance to new nuclear siting near data-center corridors. The AI-power trade has pulled nuclear developers into the center of equity narratives, but hyperscaler power-purchase agreements tend to move slowly; Oklo and NuScale have both been cited as subject to headline-driven volatility that may not reflect underlying contract progress. At 15.3% in a single session on fuel-pellet news, NuScale's stock is priced for momentum as much as fundamentals.

The pellet milestone is best understood as a necessary but not sufficient step. Safety-grade fuel production demonstrates that NuScale's manufacturing supply chain can meet NRC quality standards — the baseline prerequisite for a first-of-a-kind commercial build — but the critical path now runs through contract execution. Three developments are worth tracking in the months ahead. First, whether the TVA discussions progress from reported talks to a signed letter of intent or memorandum of understanding; that would be the most credible indication yet that a U.S. utility is prepared to commit capital to an SMR project. Second, whether any of NuScale's active commercial conversations — with Nucor, energy-center developers, or AI-adjacent data-center operators — converts to a binding purchase agreement; Seeking Alpha identified the first module order as a potential inflection point as recently as August 30. Third, how the fuel supply chain consolidates: the Curio-Framatome arrangement and the MillenniTEK production node are early links in a chain that will need to scale by orders of magnitude before a gigawatt-class deployment is viable. Until contracted capacity appears on NuScale's order book, the distance between its regulatory achievement and its commercial reality remains the defining tension in the investment case.
