NuScale Power Soars on U.S. Army's Nuclear Microreactor Program

As of November 11, 2025, NuScale Power (NYSE: SMR), a leading developer of small modular nuclear reactors (SMRs), has seen its stock surge to new heights in recent weeks. The company's shares reached an all-time high of $57.42 on October 16, 2025, though they have since fallen back slightly, ending the month up 24.6%.

The primary driver behind NuScale Power's recent stock surge was a major announcement from the U.S. Department of Defense. In October 2025, the U.S. Army unveiled a next-generation nuclear power program called the Janus Program, which aims to secure a steady and reliable supply of power across defense installations to support critical missions. The Janus Program plans to deploy nuclear microreactors at military bases worldwide, and NuScale Power, as the only company to have received design approvals from the U.S. Nuclear Regulatory Commission for its SMR technology, is well-positioned to partner with the Army on this initiative.

In another significant development, NuScale Power announced that its exclusive partner ENTRA1 Energy could receive up to $25 billion in funding under the new $550 billion U.S.-Japan Framework Agreement. This funding would be a major milestone for NuScale Power, as ENTRA1 is the company's exclusive commercialization partner, responsible for developing energy plants powered by NuScale's SMR technology. This opportunity comes on the heels of ENTRA1 signing an agreement to deploy up to 6 gigawatts of nuclear power capacity using NuScale's SMRs for the Tennessee Valley Authority across seven states.
