This work establishes and describes a new nuclear electric propulsion technology category for achieving a much lower system alpha in future space transport vehicles to significantly reduce transit time to Mars and other deep space science mission destinations. The new power conversion technology combines the Brayton cycle with a thermoacoustic Stirling cycle into a Closed Strayton Quad Generator that significantly increases the efficiency, specific power, and maximum turbine inlet temperature while insuring high reliability and long-life operation. A proposed design of this power conversion system is presented along with a performance and mass comparison to current state of practice.
