THE NASA NUCLEAR ELECTRIC POWER PROGRAM

The aim of the NASA nuclear electric power program is to provide long-lived reliable nuclear power sources in the range from tens of watts to tens of megawatts for advanced missions. The work is conducted in corporation with the U.S. Atomic Energy Commission which is developing isotope power sources and the reactor for the SNAP-8 project. Isotopes are considered for missions requiring up to several hundred watts of power. SNAP-8 will provide about 35 to 60 kilowatts for missions requiring tens of kilowatts and lifetimes of about one year. SNAP-8 has been redesigned to emphasize reliability and performance. This decision permits many components to operate at lower, more nearly state-of-the -art temperatures at the sacrifice of greater cooling requirements and increased weight. Beyond SNAP-8, an extensive applied research program has been conducted since 1959 to provide the technology required for the sound development of light weight nuclear electric systems in the megawatt range for lifetimes of up to several years. The work is accomplished in university, industrial and government laboratories.
