TPV conversion of nuclear energy for space applications

Abstract

This paper explores the possibility of achieving high conversion efficiencies in a closed loop TPV system by replacing the typical combustion thermal source with a nuclear thermal source such as a high temperature gas cooled reactor. Possible applications are nuclear electric propulsion, long‐term power for mission support systems, and terrestrial base nuclear power systems. The emitter portion of the system utilizes a novel low temperature processing technique, while the collector portion of the system utilizes a holographic concentrator/spectral splitter to reduce cell area and remove off‐band emissions.
