Flying Reactors

One of the challenges Gen. John P. Jumper, Chief of Staff of the Air Force, sends to Air Force students, researchers, and staff offices is to investigate future concepts of operations (CONOPS). One in particular relates to this study, the CONOPS for space and command, control, communications, computers, intelligence, surveillance, and reconnaissance. The Air Force is very sensitive about incorporating new technology into its operations. While the authors advocate a feasibility study for reactor sin space in a CONOPS, they also explore a deeper problem with widespread theoretical employment of nuclear technology in space. They point first to the mission enabling advantages of nuclear reactors in space - factors like light weight, high power, long life, and potentially lower costs. A reactor would supply electrical power to a space vehicle and perhaps provide ionic or electrical propulsion. They see that nuclear-powered spacecraft would serve long-range National Aeronautics and Space Administration (NASA) missions as well as permit effective hyperspectral satellites that would have profound benefits for the Department of Defense. The limiting factors for nuclear power in space are a compelling mission requirement and broad acceptance in popular support. The first factor is rather obvious but the second is driven by a broad-based fear of risks in the employment of nuclear technology. Many have general doubts about such an undertaking. Some opponents perceive cataclysmic dangers. A failure of space launch carrying nuclear systems would produce something on the order of a "dirty" nuclear bomb. Opponents are rigorous in their protest. Two things were clear to these researchers. One, nuclear space developers must convince the public that they are capable of developing a safe and robust system. Two, because the political battle is primarily over perceived risks rather than empirically based understanding, employment of value-focused decision strategy is necessary to convince the public and congressional leaders of the feasibility of a space nuclear program.
