NuScale Power Faces Lawsuits Despite Exclusive NRC Design Approval

NuScale Power holds a first-mover advantage as the only developer with U.S. Nuclear Regulatory Commission design certification for its 50-megawatt and 77-megawatt small modular reactor modules. The company is currently executing a phased initiative with RoPower Nuclear in Romania and a 6-gigawatt deployment plan with the Tennessee Valley Authority through a partnership with ENTRA1 Energy.

Despite these projects, the company faces severe financial volatility and legal challenges. Net losses increased 160% to $355.8 million in 2025, and first-quarter revenue for 2026 was nearly nonexistent. NuScale is also the target of class-action lawsuits alleging executives misled investors regarding the operational capabilities of ENTRA1 Energy. The company has already paid ENTRA1 a $495 million milestone payment, with potential future obligations reaching $3 billion.

NuScale's track record is marked by the 2023 collapse of a project with Utah Associated Municipal Power Systems after costs surged from $3 billion to $9.3 billion. While analysts project revenue growth to $310.7 million by 2028 from engineering and consulting, the company is not expected to be profitable until reactors activate in the early 2030s. Adding to the instability, former majority shareholder Fluor Corporation recently liquidated its remaining holdings in the company.
