Nuclear and thermal analysis of the heatpipe power and bimodal systems

This paper discusses the nuclear and thermal analysis of two fission‐powered concepts: the Heatpipe Power Systems (HPS) that provides power only, and the Heatpipe Bimodal System (HBS) that provides both power and thermal propulsion. The HPS and HBS systems can provide substantial levels of power and propulsion at low mass, with a high degree of safety and reliability. The systems have been designed to utilize existing technology and facilities, which will make the development cost relatively low.
