			Note a fuel cell is added while the reactor's temperature is too high, drawing the maximum amount of power from the steam turbines, the reactor will max out its temperature and lose energy. As such, it is important to have the test temperature be low enough, relative to the amount of power being consumed, that the reactor will not hit 1000 C before the cell is fully consumed.
