A detailed study is presented of some fundamental problems connected with the realization of a nuclear gaseous reactor rocket engine. The virtue of such a propulsion scheme is that the energy of the fission fragments is transferred directly to the propellant. Thus the heat-transfer problem of the conventional heat exchanger type of nuclear rocket is avoided and very high values of the specific impulse (>1000 sec) might be achieved. The discussion centers mainly around contaainment of the propellant gases during heat addition, maintaining the nuclear chain reaction, and an assessment of the principal factors contributing to cost. It is shown that reasonable values of cost per unit payload are to be achieved only by considering payloads about two orders of magnitude larger than any of current interest. Possible means for improving the situation, such as dissociation-recombination effects, pulsed operation, centrifugal separation of nuclear fuel and propellant, are investigated without reaching favorable results.

Download Gas-Core Nuclear Rocket Design Book in PDF, ePub and Kindle
Originally written in 1989, this book (Master's Thesis) reviews the state of the art in Gas-Core Nuclear Rocket design at the time of program termination in the 1970's, with updates for research performed during the 1980's. Major design problems are addressed and a proposal for an optimum design is included. This book may be especially appealing when one considers NASA's renewed mission to pioneer the future in space exploration.

Interest in rockets that use fission reactors as the heat source has centered on manned flights to Mars. The demands of such missions require rockets that are several times more powerful than the chemical rockets in use today.Rocket engines operate according to the basic principles expressed in Newton's third law of motion: for every action there is an equal and opposite reaction. In a chemical rocket, hot gases are created by chemical combustion; in a nuclear rocket heating of the propellant in a nuclear reactor creates hot gas. In either case, the hot gases flow through the throat of the rocket nozzle where they expand and develop thrust.Extensive development effort has been expended on nuclear rockets. The nuclear Rover/ NERVA rocket programs provide a very high confidence level that the technology for a flight nuclear rocket exists. These programs demonstrated power levels between 507 MWt and 4,100 MWt and thrust levels of up to 930 kN (200,000 Ibf). Specific impulse, a measure of rocket performance, was more than twice that of chemical rockets. Ground testing and technology development has been done on several concepts described in this book. However, though there appear to be no technical barriers to the development of a successful nuclear rocket, no nuclear rockets have been flown in space.This book describes the fundamentals of nuclear rockets, the safety and other mission requirements, developmental history of various concepts both in the U.S. and Russia, and it summarizes key developmental issues.

"Gaseous-fuel nuclear reactors are described their distinguishing feature is the use of fissile fuels in a gaseous or plasma state, thereby breaking the barrier of temperature imposed by solid-fuel elements. This property creates a reactor heat source that may be able to heat the propellant of a rocket engine to 10,000 or 20,000 K. At this temperature level, gas-core reactors would provide the breakthrough in propulsion needed to open the entire solar system to manned and unmanned spacecraft. The possibility of fuel recycling makes possible efficiencies of up to 65 and nuclear safety at reduced cost, as well as high-thrust propulsion capabilities with specific impulse up to 5000 sec."--NTIS abstract.
