When the program is computing the fusion power for your reactor and
your score , it also determines the temperature
of the plasma. The temperature is just the way a
scientist measures how fast the electrons and ions in the plasma
are moving around.
comparison, the temperature in the center of the Sun is 15
million degrees Celsius! Tokamak plasma temperatures need to be
hotter than those in the Sun since tokamak plasma densities are much
lower than the Sun's.
