    Well, a nuclear-electric propulsion system is on the order of ten or twenty times more efficient than your typical high-performance liquid hydrogen liquid oxygen chemical propulsion rocket such as J-2X or RS-25. BUT (and this is a really, really big “but”), for all that efficiency, they don’t generate much thrust.

    Nickel-base superalloys proposed for use in A-USC boiler and turbine systems typically have upwards of 20–25 % Cr, which means that they form essentially pure Cr 2 O 3 scales. Minor amounts of Mn, Si, and Ti are also found in Cr 2 O 3 scales. Most of these alloys also contain Al and Ti, which internally oxidize.
