Book excerpt: This unique book reproduces important government documents, reports, and studies dealing with spaceflight nuclear power and propulsion technologies, including Radioisotope Thermoelectric Generators (RTGs), Plutonium-238 production, NASA Kilopower Fission Reactor (KRUSTY) and nuclear thermal propulsion (NTP) rockets for human Moon and Mars exploration.Contents include: Overview of Space Radioisotope Power Systems and RTGs * Advanced Radioisotope Power System Concepts and Designs * Energy Department and Plutonium Production * Space Exploration - DOE Could Improve Planning and Communication Related to Plutonium-238 and Radioisotope Power Systems Production Challenges * Nuclear Thermal Propulsion (NTP) * NASA's Kilopower Fission Reactor Program and KRUSTYRadioisotope Thermoelectric Generators, or RTGs, provide electrical power for spacecraft by converting the heat generated by the decay of plutonium-238 (Pu-238) fuel into electricity using devices called thermocouples. Since they have no moving parts that can fail or wear out, RTGs have historically been viewed as a highly reliable power option. Thermocouples have been used in RTGs for a total combined time of over 300 years, and a not a single thermocouple has ever ceased producing power. Thermocouples are common in everyday items that must monitor or regulate their temperature, such as air conditioners, refrigerators and medical thermometers. The principle of a thermocouple involves two plates, each made of a different metal that conducts electricity. Joining these two plates to form a closed electrical circuit while keeping the two junctions at different temperatures produces an electric current. Each of these pairs of junctions forms an individual thermocouple. In an RTG, the radioisotope fuel heats one of these junctions while the other junction remains unheated and is cooled by the space environment or a planetary atmosphere.Benefits of NTP propulsion include: For human Mars missions, first generation NTP can reduce crew time away from earth from greater than 900 days to less than 500 days while still allowing ample time for surface exploration; reduce crew exposure to space radiation, microgravity, other hazards; can enable abort modes not available with other architectures including the potential to return to earth anytime within 3 months of earth departure burn, also to return immediately upon arrival at Mars; and stage/habitat optimized for use with NTP could further reduce crew exposure to cosmic rays and provide shielding against any conceivable solar flare.
Download or read book Priorities in Space Science Enabled by Nuclear Power and Propulsion written by National Research Council and published by National Academies Press. This book was released on 2006-03-20 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2003, NASA began an R&D effort to develop nuclear power and propulsion systems for solar system exploration. This activity, renamed Project Prometheus in 2004, was initiated because of the inherent limitations in photovoltaic and chemical propulsion systems in reaching many solar system objectives. To help determine appropriate missions for a nuclear power and propulsion capability, NASA asked the NRC for an independent assessment of potentially highly meritorious missions that may be enabled if space nuclear systems became operational. This report provides a series of space science objectives and missions that could be so enabled in the period beyond 2015 in the areas of astronomy and astrophysics, solar system exploration, and solar and space physics. It is based on but does not reprioritize the findings of previous NRC decadal surveys in those three areas.

In the vast expanse of space exploration, where the challenges are as numerous as the stars themselves, the role of nuclear power cannot be overstated. This book serves as a comprehensive guide to understanding the pivotal role of nuclear technology in powering space missions, addressing the intricate nuances of nuclear cooling systems, space reactors, and propulsion technologies. As humanity ventures further into the cosmos, the demand for reliable and efficient power sources becomes increasingly urgent. Nuclear power stands at the forefront of this quest, offering unparalleled energy densities and longevity essential for extended missions beyond Earth's orbit. However, harnessing nuclear energy in the vacuum of space presents unique challenges and opportunities, which this book endeavors to explore in depth. From the fundamental principles of nuclear reactors to advanced propulsion systems capable of interstellar travel, each chapter delves into specific aspects of nuclear technology relevant to space exploration. We examine the intricacies of cooling systems, the adaptability of nuclear reactors to diverse mission requirements, and the cutting-edge innovations shaping the future of space propulsion. Moreover, safety is paramount in the utilization of nuclear power, particularly in the context of space missions where the stakes are high and the environments harsh. Throughout this book, we emphasize the importance of stringent safety protocols, redundancy measures, and contingency planning to mitigate risks associated with nuclear power in space. Furthermore, this book serves as a testament to the interdisciplinary nature of space exploration. From materials science to artificial intelligence, from propulsion engineering to cybersecurity, the integration of various fields is essential to unlocking the full potential of nuclear technology in space. Whether you are a seasoned aerospace engineer, a budding space enthusiast, or simply curious about the future of space exploration, "Introduction to Nuclear Power in Space: Nuclear Cooling Systems, Space Reactors, and Propulsion Technologies - Book 1" offers a comprehensive and accessible resource. We hope that this book inspires and enlightens readers about the boundless possibilities that nuclear power holds for humanity's journey among the stars.

Book excerpt: Chemically propelled rockets can lift less than 5 percent of their take-off weight into orbit, a fact that could forever limit the space program. Nuclear-powered rockets, however, with their superior thrusting power and speed, are radically different. So argues James A. Dewar in the only comprehensive history ever written of the nuclear rocket project. It is a story of political battles over the space program's future, involving Presidents Eisenhower, Kennedy, Johnson and Nixon, and a readable account of its technical successes, a story perhaps more interesting and certainly more important, Dewar believes, than the history of atomic and H-bomb development. Dewar maintains that only by reestablishing a nuclear rocket project can the nation have a space program worthy of the 21st century, one that makes reality of the hopes and dreams of science fiction.

Book excerpt: 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.
