Nuclear Propulsion for Space Applications
Nuclear Propulsion for Space Applications by M. G. Houts, published by BiblioLife in June 2013, offers a detailed exploration of nuclear systems used in space missions. This 38-page book discusses the long history of nuclear technology, including its applications in the Apollo program and various space science missions. It highlights the use of radioisotope thermoelectric generators (RTGs) and radioisotope heater units (RHUs) launched by the U.S. over the past four decades, focusing on the energy produced from the decay of plutonium and the fission of uranium.
Readers will find a comprehensive overview of the principles behind nuclear propulsion, including the mechanics of heat production from alpha particle decay and neutron-induced fission. The book explains how fissioning uranium can yield energy equivalent to burning millions of kilograms of coal and details the operational history of U.S. and former U.S.S.R. space reactors. By examining the versatility of fission for both electricity generation and propellant heating, this edition provides insights into the potential applications of nuclear technology in space exploration and beyond.
Official synopsis Publisher
Basics of Nuclear Systems: Long history of use on Apollo and space science missions. 44 RTGs and hundreds of RHUs launched by U.S. during past 4 decades. Heat produced from natural alpha (a) particle decay of Plutonium (Pu-238). Used for both thermal management and electricity production. Used terrestrially for over 65 years. Fissioning 1 kg of uranium yields as much energy as burning 2,700,000 kg of coal. One US space reactor (SNAP-10A) flown (1965). Former U.S.S.R. flew 33 space reactors. Heat produced from neutron-induced splitting of a nucleus (e.g. U-235). At steady-state, 1 of the 2 to 3 neutrons released in the reaction causes a subsequent fission in a “chain reaction” process. Heat converted to electricity, or used directly to heat a propellant. Fission is highly versatile with many applications.
