Project 242[44] based on Rubbia design studied a concept of 242mAm based Thin-Film Fission Fragment Heated NTR[45] by using direct conversion of the kinetic energy of fission fragments into increasing of enthalpy of a propellant gas. oxygen and kerosene) heat the by-products of the chemical reaction (e.g. How would a Nuclear Salt Water Rocket (NSWR) compare to rocket fuel? The design relies on the development of fusion power technology beyond current capabilities, and the construction of rockets much larger and more complex than any current spacecraft. How to prevent players from sabotaging themselves by engaging in long arguments about what to do next?

NERVA NRX/XE produced the baseline 75,000 lbf (334 kN) thrust that Marshall required in Mars mission plans. [1] [7], Another major limitation of the nuclear salt water rocket design by Robert Zubrin included the lack of a material to be used in the reaction chamber that could actually sustain such a reaction within a spacecraft.

Heat transfer to the working fluid (propellant) is by thermal radiation, mostly in the ultraviolet, given off by the fission gas at a working temperature of around 25,000 °C.

This yields a specific impulse of around 7000 seconds, making the engine 15.5 times more efficient* than the Space Shuttle's main engines, which are in turn just about the most efficient chemical rockets possible. Would a hibernating, bear-men society face issues from unattended farmlands in winter? On which hinge(s) should hinge pin doorstops be installed? A nuclear salt-water rocket (or NSWR) is a proposed type of nuclear thermal rocket designed by Robert Zubrin that would be fueled by water bearing dissolved salts of plutonium or U 235. Once the reactor has been started for the first time, extremely radioactive short-life fission products are produced, as well as less radioactive but extremely long-lived fission products. [ citation needed ] This question can be perhaps answered by detailed Monte-Carlo simulations of neutron transport.

Another report claims that 242mAm can sustain a chain reaction even as a thin film, and could be used for a novel type of nuclear rocket.[32][36][37][38].
