Configure FFT fission engines, including
-Dusty Plasma Fission Fragment Rocket Engine
-Dusty Plasma Afterburning Fission Fragment Rocket Engine
-10 m "Mini-Mag" Orion
-20 m "Mini-Mag" Orion
-20 m Nuclear Salt Water Rocket
Also configure radiators for more realistic properties, and change System Heat so it obeys the Stefan-Boltzmann law.
