NASA successfully tests portable nuclear reactor for crewed missions to Mars.

  • The project provides 10 kilowatts of electrical power continuously for minimum of 10 years.
  • NASA and the Department of Energy’s National Nuclear Security Administration (NNSA) have successfully demonstrated a miniature nuclear reactor power system that
  • Dubbed Kilopower, the small, lightweight fission system is able to provide up to 10 kilowatts of electrical power continuously for a minimum of 10 years.
  • Pair a few units together and you’ve suddenly got enough power to establish an outpost, NASA says.
  • The prototype uses a solid, cast uranium-235 reactor core which is roughly the size of a paper towel roll.
  • Reactor heat is transferred via passive sodium heat pipes to high-efficiency Stirling engines which convert the heat to electricity.
