Summary of SNAP 8 reactor design and shielding requirements; 35-kw electrical power supply for use on spacecraft employs nuclear reactor heat source to drive mercury Rankine cycle turboalternator; major performance objectives are 600 kw of thermal power, 1300 F NaK outlet temperature, 10,000 hr endurance, orbital startup and automatic control, high reliability, and low weight; use of 550 lb reactor imposes restrictions on spacecraft design; shield weight can vary from few hundred to several thousand pounds, depending on payload dose tolerance and spacecraft configuration.
