Re: Nuclear Powered Aliens
Well, cosmic radiation is around 2 rads per week in deep space, so it is unlikely to work. I honestly would have the biological spacecraft use biological fusion reactors that use deuterium-deuterium reactions and which produce helium-3 and tritium as byproducts. Much like humans replace the lining of their stomachs, the biological spacecraft would replace the lining of their reactor chambers, replacing radioactive components with newly grown components, and excreting the radioactive components as waste. They could graze on asteroids and comets for the materials that they need and trade the helium-3 and tritium to humans in exchange for human technology.
