A Martian Nuclear Power Plant is described, based on the nuclear technologies developed and demonstrated in the NERVA nuclear propulsion program. The reactor is in a closed-cycle system, employing an inert gas coolant, while the power-turbine generator system is an open-cycle gas turbine which uses the Martian atmosphere as a working fluid. The two systems are connected by a double-walled heat exchanger which transfers energy from the reactor to the power turbine system. The plant is rated at 3 MWe and is capable of three years of power operation, at a capacity factor of 90 percent, before the fuel is depleted. The plant is arranged in modules, which are fully constructed on earth and then interconnected on the surface of Mars. A preliminary estimate of the module contents and masses leads to a total plant specific mass of 25.3 kg/kWe.
