I am unable to figure out how to change the size of the reactor core for nuclear thermal rocket, how do I do this?

You do it with "Chamber Contraction Ratio", "Throat Radius" and "Reactor Core Height" sliders. All your fuel, moderator, rods and reflectors will take space in there, click accordingly.
Also be aware that the "Pump Radius" and, in turn, "Gimbal \ Inner Radius" both contribute to overall NTR width, as is "Gimbal Angle" (there are two distinct geometrical possibilities - less than 45°, or between 45.1° and 90°) and, as a consequence, nozzle length (yes).
