NuScale Power's stock soared 8.88% intraday on Tuesday, as the U.S. nuclear power sector experienced a collective strengthening.

The rally was driven by a clear sector linkage effect, with multiple stocks within the nuclear and heavy electrical equipment space posting synchronized gains. This broad-based momentum across the sector indicates renewed investor interest in nuclear energy technologies.

NuScale Power Corporation, which is redefining nuclear energy through its proprietary small modular reactor technology, benefited from this sector-wide upward movement. The company's core NuScale Power Module generates 77 MWe of electricity, while its flagship VOYGR power plant design can house up to 12 modules for a total output of 924 MWe.
