Most of the Radioisotope Power Systems (RPS) Program assembly and testing operations take place in the 792A annex, which comprises most of the Space and Security Power Systems Facility (SSPSF). Building 792, adjacent to the 792A annex, is used for administration and operations support functions, including equipment storage. Building 792 is a non-nuclear, nonradiological facility, while the 792A annex is a Hazard Category 2 nonreactor nuclear facility. Building 792 was originally constructed in 1971 and used for storage of various mock-up components. It is approximately 50 ft. x 60 ft. x 25 ft. tall. In 2004, the 792A annex was added.
