1966-67 NEW FILMS AERO-SPACE PROGRAMS: SNAP (Systems for Nuclear Auxiliary Power) FIRST REACTOR IN SPACE: SNAP-10A (1966) 14V 2 minutes, color. Produced for the USAEC by Atomics International. For sale by Hollywood Film Enterprises, Inc., 6060 Sunset Blvd., Hollywood, Calif. 90028, at $40.40 per print, including shipping case, F.O.B. Hollywood. Available for loan (free) from the USAEC head- quarters and field libraries nationwide, and, in California, also from the Library, Atomics Interna- tional, P. O. Box 309, Canoga Park, Calif. 91304. Development, launch and results of the world's first nuclear reactor power system to operate in space are described in this semi-technical film, which will be of interest to a wide range of audiences, including high schools. TheSNAP- 10A unit, consisting of a nuclear reactor and power conversion unit, was thrust into a 700 nautical mile, nearly circular orbit in April 1965 from Vandenberg Air Force Base, California, by an Atlas-Agena vehicle. Following remote start-up, the power plant was operated successfully for 43 days and produced more than 500,000 watt-hours of electricity. The SNAP program (Systems s for Nuclear Auxiliary Power) is being conducted by the USAEC to fill the need for long-lived sources of electrical power in space — sources not dependent on sunlight or affected adversely by the harsh environment of space. Other types of SNAP units also have application on land and in the sea. The power generated by SNAP-10A in space was used primarily to provide power for on-board experiments. But future SNAP reactor systems can supply power for many important purposes—such as to power communication systems, collect scientific data, conduct experiments in space, and supply electricity for life support systems on extended manned missions. SNAP-10A, a compact reactor, is coupled to a thermo- electric converter-radiator unit which converts heat from fission in the reactor directly into electricity. The heat is transferred to the power conversion unit by a liquid metal coolant, an alloy of sodium and potassium. The SNAP-10A system generates approximately 500 electrical watts.
