A design concept for a nuclear thermal propulsion (NTP) reactor to power future astronaut missions to Mars has exceeded key performance parameters and optimised the reactor for manufacturability, General Atomics Electromagnetic Systems (GA-EMS) has announced. The reactor's features include a compact core thanks to the use of high-assay low-enriched uranium (HALEU) fuel.

The design was produced as part of a NASA-funded study. GA-EMS said its design exceeded the key performance parameters requested by NASA.
The reactor concept incorporates advancements in modern nuclear materials and manufacturing methods with experience from GA-EMS’s involvement on NASA Atomic Energy Commission (AEC) Project Rover in the 1960s. Project Rover was one of the first programmes to demonstrate the feasibility of space-based nuclear thermal propulsion.
GA fabricated approximately six tonnes of the nuclear fuel kernels for the project. In 1965, the company was also directly involved in nuclear fuel testing and characterisation for the SNAP-10A reactor, the only US nuclear power reactor launched into space, which powered the satellite for 43 days. The fuel used for that reactor is the same fuel that has been used since the 1950s in General Atomics Triga reactors.
