Here’s a supremely unaffordable nuclear fantasy – reactors on the moon and Mars

NASA Wants to Go Nuclear on the Moon and Mars for Astronaut Settlement, SciTech Daily  By AMERICAN CHEMICAL SOCIETY MAY 31, 2020 m  It might sound like science fiction, but scientists are preparing to build colonies on the moon and, eventually, Mars. With NASA planning its next human mission to the moon in 2024, researchers are looking for options to power settlements on the lunar surface. According to a new article in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, nuclear fission reactors have emerged as top candidates to generate electricity in space.

………. Nuclear devices that run on decaying plutonium-238 have been used to power spacecraft since the 1960s, including Mars rovers and the space probes Voyager and Cassini, but they don’t provide enough energy for a settlement. In contrast, nuclear fission reactors that split uranium-235 atoms, which are used by power plants here on Earth, could provide a reliable power source for a small space settlement for several years, scientists estimate.
Despite funding and design setbacks, researchers are reinvigorating efforts to create a nuclear reactor for space travel and settlement. In the early 2010s, a team of scientists from Los Alamos National Laboratory, NASA and the U.S. Department of Energy came together with the goal of developing a new nuclear fission system that could produce at least 10 kilowatts of energy. With a core containing molybdenum and highly enriched uranium, the reactor uses nuclear fission to generate heat, which is converted to electricity by simple piston-driven engines. The prototype, which was tested in 2018, produced up to 5 kilowatts of electricity. The researchers hope to optimize the technology to achieve the desired 10-kilowatt output. They also say that transporting uranium in space can be done safely, as the alpha particles emitted by the core are weak and can be fully contained by proper shielding .   https://scitechdaily.com/nasa-wants-to-go-nuclear-on-the-moon-and-mars-for-astronaut-settlement/
