Huh? I was talking about a 40 kW space rated nuclear reactor such as those
designed for satellites. Yes it is heavy, but not because it requires lots
of fuel. The purpose of this power was to drive a very large klystron tube
which heats the hydrogen fuel into a plasma. NOW you have lots of fuel - for
the engines, not to generate power.
This engine approaches fusion engines in efficiency, making it ideal for
interplanetary missions. It could even put a probe through one of the nearer
star systems within fifty years.
