A nuclear detonation in low-Earth orbit — the region about 100 miles to 1,200 miles above Earth’s surface — would release trillions of highly energetic electrons that would destroy many of the satellites in space, disrupting telecommunications networks, GPS, space-based internet, and more
“The world’s first commercial nuclear-powered satellite, the BOHR CubeSat, launched aboard a SpaceX Falcon 9 rocket on July 7, 2026.”

I’m pretty sure it uses a combination of solar and betavoltaic’s tritium battery
