NuScale Power’s shares jumped nearly 13% by midday Friday, despite no company-specific announcements or new contracts. This surge outpaced the broader energy sector rally and reflects heightened investor enthusiasm for small modular reactor (SMR) technology. Trading volume surged to roughly 900,000 shares, well above the three-month daily average of 240,000, suggesting momentum-driven buying rather than a reaction to fundamental news.

The uptick coincided with reports of a temporary shutdown at Finland’s Olkiluoto Nuclear Power Plant, where unit OL2 went offline due to a software update glitch in the power management system. Plant operators expect the reactor to return to service within 16 hours, emphasizing that safety protocols functioned as designed and the other two units continue normal operation. Some investors appear to view this incident as a potential catalyst for accelerated adoption of SMRs, which proponents argue offer greater flexibility and reduced downtime risk compared to large conventional reactors.

Despite its first-mover advantage—holding the only U.S. Nuclear Regulatory Commission–approved SMR design—NuScale Power remains unprofitable. The company reported a gross margin of 65% in its latest quarterly filing but has no profit forecast before 2030. Market capitalization stands at approximately $4.0 billion, yet the firm has yet to secure binding sales agreements beyond preliminary memoranda of understanding with Romania’s RoPower and Tennessee Valley Authority affiliate ENTRA1 Energy. Investors are cautioned that momentum-driven gains could reverse sharply if NuScale fails to convert these potential deals into firm orders and generate positive free cash flow.
