Advanced development and using of space nuclear power systems as a part of transport power supply modules for general purpose spacecraft

Abstract: Nuclear transport power systems (NTPS) can provide solving such important science, commerce and defense tasks in space as radar surveillance, information affording, global ecological monitoring, defense of Earth from dangerous space objects, manufacturing in space, investigations of asteroids, comets and solar systems’ planets (Kuzin et al. 1993a, 1993b). The creation of NTPS for real space systems, however, must be based on proved NTPS effectiveness in comparison with other power and propulsion systems such as, nonnuclear electric‐rocket systems and so on. When the NTPS effectiveness is proved, the operation safety of such systems must be suited to the UN requirements for all stages of the life cycle in view of possible failures. A nuclear transport power module provides both a large amount of thermal and electrical power and a long acting time (about 6–7 years after completing the delivery task). For this reason such module is featured with the high power supplying‐mass delivery effectiveness and the co...

Space power technology

Abstract: The trends today are toward smaller satellites with increased capability. These two trends place enormous demands on the technology used to power such space systems. Typical power sources are nuclear, photovoltaic, and chemical. As the power available on a typical satellite decreases, the use of long pulsed power sources becomes more attractive. Technologies such as electrochemical capacitors, pulsed batteries and flywheels offer the possibility of employing high power subsystems for limited times without undue burden on the spacecraft power train. The state of the art in each of the pulsed storage devices is discussed and preliminary experiments described which use an electrochemical power source to power a spacecraft propulsion unit such as an arc-jet or Hall effect thruster.

Multi-cell thermionic fuel element for nuclear electric power and propulsion system

Abstract: Conceptual problems of development of two-mode multi-cell thermionic fuel element (TFE) for nuclear electric power and propulsion system are considered. The results of analysis of the design and TFE output parameters are presented. It is shown that application of advanced high effective materials and technologies provides operating of the TFE in two modes: a) in nominal mode of power generation for power supply of spacecraft payload at operational orbit and b) in forced mode of power generation for power supply of electric thrusters under spacecraft orbit transfer from intermediate to operational one.
