Constellation Energy Corp's stock surged 5.03% during intraday trading on Tuesday, reflecting strong investor interest in the nuclear energy sector.

The rally was driven by sustained optimism around AI-related electricity demand and the positive impact of a recent U.S. Department of Energy emergency order. The DOE directive instructed regional grid operator PJM Interconnection to coordinate with Constellation Energy to ensure critical generating units at its Eddystone power station in Pennsylvania remain operational, highlighting the company's strategic importance within U.S. power infrastructure and grid reliability.

The upward movement occurred alongside gains in other nuclear energy stocks, indicating broader sector strength. Investors are showing increased confidence in companies positioned to benefit from growing electricity demands and supportive government energy policies.
