Feasibility of Colloid Core Nuclear Reactor for Rocket Propulsion.
Abstract
An in-depth study has been conducted to determine the feasibility of the colloid core nuclear reactor (CCNR) for rocket propulsion. Investigations of powder containment, reactor criticality, nuclear fuel vaporization, heat transfer, and wall erosion are discussed. Results are scaled and integrated to specify an optimized design reactor rocket engine. Rocket engine performance is evaluated with respect to velocity capability, type of fuel, and fuel loss rate. It is concluded that the CCNR rocket engine is technically feasible, that a thrust-to-weight ratio of 6:1 is obtainable at 20,000 lb thrust, and that the maximum specific impulse cannot exceed 1020 sec. Furthermore, results indicate that the CCNR shows significant performance advantages over chemical and other nuclear rocket engines for missions requiring payloads on the order of 10,000 lb, with large excess velocity capability. Recommendations are made as to the steps necessary to the further development of the colloid core nuclear reactor rocket. (Author)
