Document Type: Proceeding Paper

Part of: Engineering, Construction, and Operations in Space IV


The TOPAZ II single-cell thermionic space reactor power system was designed, built and tested by the former Soviet Union (Russia). It has been purchased by the United States (U.S.) for technology transfer, testing, and the possible integration and launch with a U.S. satellite. To support the program, ground facilities consisting primarily of Russian hardware, have been built in Albuquerque, New Mexico to perform non-nuclear ground testing of the system. The purpose of this paper is to provide a brief overview of the Russian TOPAZ II system.
