The last time NASA tested a fission reactor was during the 1960s' Systems for Nuclear Auxiliary Power, or SNAP, program, which developed two types of nuclear power systems. The first systemThe Multimegawatt Program Taking Space Reactors to the Next Level A s development of a 100kilowatt electric space reactor power system progressed under the SP100 program, spacebased weapon and sensor designs continued to evolve under SDI. As the vision for global defensive systems capable of protecting against the space reactor power systems

Nuclear reactor power systems could revolutionize space exploration and support human outpost on the moon and Mars. This paper reviews various energy conversion technologies for use in space reactor power systems and provides estimates of the system's net efficiency and specific power, and the specific area of the radiator.

Nuclear power in space is the use of nuclear power in outer space, typically either small fission systems or radioactive decay for electricity or heat. Another use is for scientific observation, as in a Mssbauer spectrometer. One common type is a radioisotope thermoelectric generator, which has been used on many space probes and on manned lunar missions, and another is small fission reactors . 2. Initiating Events for Mars Base Power System 214 6. 7. Finding 9: There appears to be no reason that a space nuclear reactor power system cannot be safely deployed and operated on the surface of another world while maintaining standards of planetary protection. 216 6. 8. Finding 10: A Space Reactor System Enables Effective of Design space reactor power systems Controllable reaction rate (variable power levels) Used terrestrially for over 70 years Fissioning 1 kg of uranium yields as much energy as burning 2, 700, 000 kg of coal One US space reactor (SNAP10A) flown (1965) Former U. S. S. R. flew 33 space reactors Heat produced from neutroninduced splitting of a nucleus (e. g. U235)

metal heat pipes in space reactor systems, and the modeling capabilities of the startup from a frozen state. In addition to models validation, results of design optimization of liquidmetal and water heat pipes in a number of space reactor power systems are presented and discussed. space reactor power systems The Department of Energy (DOE) and its predecessors have provided radioisotope power systems that have safely enabled deep space exploration and national security missions for five decades. Radioisotope power systems (RPSs) convert the heat from the decay of the radioactive isotope plutonium238 (Pu238) into electricity. Nuclear Reactors in Space! 1965SNAP 10A launched. First (and only) USA reactor in space. Thermal spectrum, NaKcoolant, 590We maximum operation, 43 days Reactor power systems are seen as an exciting enabling technology for largescale exploration missions: Space Power Systems. Radioisotope power systems can heat and power autonomous machinery for extended operation periods. INL assembles such generators by adding the radioactive power source. A team of INL experts then conducts extensive testing to ensure the device will be able to withstand conditions it will experience during the rocket launch The SNAP10A was a spacequalified nuclear reactor power system launched into space in 1965 under the SNAPSHOT program. It was built as a research project for the Air Force, to demonstrate the capability to generate higher power than RTGs.
