SNAP (Systems for Nuclear Auxiliary Power) A program of experimental radioisotope thermonuclear generators (RTGs) and space nuclear reactors flown during the 1960s. Odd-numbered SNAPs were RTG tests and even-numbered SNAPs were reactor system tests. The United States flew only one complete nuclear reactor, aboard the SNAPSHOT mission.
