Book excerpt: The results of a study of the installation and operational characteristics of a SNAP reactor system integrated with a manned space station are presented. The reference system selected was an 11 kw(e) version of a SNAP 2 system employing multiple power conversion units coupled to a single reactor source. Of prime importance is the reactor radiation shield required for the manned system and the use of design features which minimize the shield weight. The weight of the radiation shield is highly dependent upon the geometrical configuration of the space station and the reactor since shadow'' shielding of the manned compartments is required for minimum weight systems. The installation and shielding requirements of the 11 kw(e) system were considered for two types of space station configurations; one was a 10 ft dia cylindrical station with a reactor separation distance of 50 ft and the other a 150 ft dia toroidal station with the reactor located in the hub. The weight of the power system installed in the cylindrical space station was about 9000 lb of which 6000 lb was required for shielding. The weight of the system for a toroidal station was approximates 25,000 lbs of which 20,000 lbs was required for shielding. However, these weights are relatively insensitive to power level and doubling or tripling the power output will only increase these weights by a small percentage. In addition, the designs developed for these two concepts permit the replacement of the reactor and power conversion system with the radiation shields becoming essentially a permanent part of the space station. Hence the large weight penalty associated with the reactor shield only has to be incurred once during the life of the space station. Because of the dominance of the reactor shield weights for manned systems, parametric curves of shielding weight are presented to enable the space vehicle designer to estimate nuclear power system weights for configurations other than those selected in this report.

Available in PDF, EPUB and Kindle. Book excerpt: Declassified 6 Sep 1973. The charactenistics of the SNAP-50/SPUR power plant adapted to a typical large orbiting manned space station are described. Power plants of both 35 and 300 kW net electrical output were considered. The 35 kW(e) system was selected as being representative of the minimum power level at which it appears that nuclear reactor power plants are clearly competitive with nonnuclear systems. The larger power level was selected to determine the characteristics of the 300 kW(e) SNAP-50/SPUR reference power plant when adapted to this application. In modifying the basic SNAP-50/SPUR power plant concept for manned applications, it was necessary to provide power conversion system redundancy and increased meteoroid protection in the heat rejection systems. To limit radiation in the space station to suitable levels for crew occupancy, the reactor system and all components containing highly radioactive fluids are located within the shield envelope. Furthermore, the lifetime goal of the space station (5 years) exceeds the design lifetime of the power plant (10,000 hours = 1.2 years); therefore, a design to facilitate power plant removal and replacement was incorporated. Since the shield weight is such a large portion of the over- all weight, a concept was evolved in which about 75 percent of the shieid remains permanently attached to the apace station and the remaining 25 percent is removable and replaced with the power plant.
