An experimental loop for simulating nuclear reactors in space

Nuclear thermal propulsion, which uses heat from nuclear reactions as fuel, could be used one day in human spaceflight, possibly even for missions to Mars. Its development, however, poses a challenge. The materials used must be able to withstand high heat and bombardment of high-energy particles on a regular basis. A nuclear engineering doctoral student is contributing to research that could make these advancements more feasible.
