The Brayton Isotope Power System (BIPS) is being developed to provide 1.3 kilowatts of electric power for space use with mission durations in excess of five years and a reliability greater than 0.95. These design goals will be achieved initially utilizing superalloy hot-end components operating at a turbine inlet temperature of 760 Cel or lower. With proper refractory metal component development, these goals ultimately will be achieved at a turbine inlet temperature of 871 Cel, which will result in a significant reduction in total system weight. This discussion presents a comparison of system performance and the rationale for employing the BIPS as a low temperature dynamic power system using the same rotating machinery. In addition, the versatility of the BIPS is shown by examining the cycle efficiency (temperature) and power growth capabilities of the system.
