NuScale Power's stock surged 14.87% during intraday trading on Tuesday, as the small modular reactor specialist led a broad rally across the nuclear energy sector.

The sharp rise follows a landmark regulatory decision, with U.S. authorities approving the first non-light-water reactor design in over four decades. This approval is seen as a powerful catalyst for the entire small modular reactor industry, directly benefiting companies like NuScale Power.

Furthermore, increasing investments from technology giants into nuclear energy, driven by the demand for power-intensive AI infrastructure, have bolstered sector sentiment. Strategic partnerships, such as Framatome's deepening collaboration with NuScale on SMR fuel, have also reinforced the company's commercial outlook, contributing to the strong investor confidence reflected in today's price movement.
