Space Nuclear Propulsion: History, Cost, and Status of Programs
Abstract
DOD and NASA are pursuing separate approaches to develop space nuclear thermal propulsion programs. The DOD program differs from the NASA approach primarily in the manner in which the nuclear fuel is packed in the reactor. NASA's approach, based on technology developed and tested from 1955 to 1972, involves the use of nuclear fuel encased in rods. DOD's approach envisions use of a nuclear fuel encapsulated in very small particles. If this particle bed reactor technology can be developed, it is expected to significantly increase the performance of future nuclear rocket engines.
