Scientific paper

Thermoelectric space reactor power systems that utilize Multi-Layer Quantum Well (MLQW) technology are presented and discussed in the context of Nuclear Electric Propulsion (NEP). Quantum wells are one of the recent developments in low-dimensional thermoelectric materials that show a factor of 2.5 increase in the thermoelectric figure of merit. This breakthrough in converter performance promises higher efficiency power generating devices. The MLQW under development at Hi-Z Technology, Inc., applied to space systems provides the design flexibility traditionally available with thermoelectric conversion in reactor power systems with higher performance. The reactor concept evaluated is the Heatpipe Power System (HPS) reactor.
