SNAP REACTOR. An Atomics International tech­nician examines the reflector of a 200-pound nu­clear reactor. It was developed for the Atomic Energy Commission as part of the SNAP (Systems for Nuclear Auxiliary Power) series of reactor-elec­tric power systems for space vehicles. The reac­tor, which is now critical, generates 50 kw. of heat
