NuScale Power Corporation experienced a significant rally on Tuesday, with shares climbing 8.6% to close near $14.00 during regular U.S. trading hours. The stock opened at $12.75 and reached an intraday high of $14.30, with trading volume exceeding 41 million shares. The company's market capitalization now stands at approximately $4.48 billion.
This surge comes as investors once again pivot toward nuclear energy stocks, driven by the escalating power demands of artificial intelligence and data centers. NuScale's movement occurred without any new contract announcements, drawing attention to the broader market sentiment rather than company-specific catalysts. Management is scheduled to present at key investor events on June 2, including the RBC Capital Markets' Global Energy, Power & Infrastructure Conference in New York.
Small Modular Reactors in Focus
NuScale offers investors a publicly traded avenue into the small modular reactor (SMR) sector. Its proprietary NuScale Power Module is an advanced SMR design capable of generating approximately 77 megawatts of electricity. Power plants can be configured with up to 12 modules, providing scalable clean energy solutions. This technology is increasingly viewed as a potential answer to the growing electricity needs of AI data centers and large-scale industrial facilities.
The nuclear energy sector broadly benefited from this renewed interest. Oklo Inc. saw its shares jump 9.4%, Nano Nuclear Energy Inc. gained 4.6%, and Constellation Energy Corporation, a major nuclear plant operator, rose 3.2%. In comparison, the SPDR S&P 500 ETF edged up 0.2%, while the Invesco QQQ Trust added 0.4%.
Regulatory Tailwinds
Regulatory developments are providing additional support. According to Reuters Events, the U.S. Nuclear Regulatory Commission (NRC) is implementing changes to accelerate the review process for SMR and microreactor projects. Adam Stein, director of nuclear innovation at the Breakthrough Institute, noted that the Part 53 process "could completely change how we license reactors." NuScale holds a key advantage: the NRC approved its 77-megawatt reactor design in May 2025, making it one of the few SMR designs to receive such certification.
Commercial Pipeline and Partnerships
NuScale's commercial efforts are centered on a collaboration with the Tennessee Valley Authority (TVA) and ENTRA1 Energy. The partnership aims to deploy up to 6 gigawatts of new nuclear capacity across TVA's seven-state region, targeting AI data centers, semiconductor fabrication plants, and other heavy energy consumers. The plan involves six ENTRA1 sites, each equipped with 12 NuScale modules. CEO John Hopkins emphasized during the company's May earnings call that "we are building the infrastructure that this pivotal moment requires."
Financial Realities and Risks
Despite the market enthusiasm, NuScale's financials remain a concern. The company reported first-quarter revenue of just $565,000 against a net loss of $46.7 million. In its regulatory filing, NuScale highlighted risks including the absence of binding customer contracts, potential manufacturing delays, cost uncertainties, reliance on partners, and the need for additional funding. The company still has approximately $962 million available under its at-the-market stock offering, which could dilute existing shareholders if utilized aggressively.
Analysts caution that the key test for NuScale lies not in Tuesday's price action but in its ability to convert its pipeline into tangible, revenue-generating agreements. "First-of-a-kind projects are being carefully watched," said Mason Lester, nuclear power analyst at S&P Global Commodity Insights, as utilities must demonstrate cost-effectiveness to ratepayers.
In summary, NuScale's latest rally underscores persistent investor appetite for nuclear energy as a solution to AI-driven power demands. However, the company's path to profitability remains uncertain, with substantial execution hurdles ahead. The stock's movement reflects hope rather than concrete progress, leaving questions about commercial viability unanswered.
