Declassified 6 Sep 1973. The SNAP-50/SPUR powerplant development program concentrates on a system designed for unattended operation in space for 10,000 hours, and which produces a net electrical output of 300 kW(e). The reactor and shield for this powerplant has been designated the PWAR-20. The powerplant weight goal for the 2-MW(t) reactor is l800 pounds, exclusive of shielding. A target weight for shielding, the design of which is mission oriented, has not been specified because mission requirements have not been clarified to date. The preliminary design of the PWAR-20 is presented. The major problem areas which exist are described. 25 references. (auth)
