Fusion Reactor
Power generation device which employs the nuclear fusion of hydrogen isotopes into helium.
These devices are incorporated into the Impulse propulsion systems aboard Federation Starships.
Numerous other 'auxiliary' fusion reactors channel power to ship's systems when the impulse and
warp systems (EPS) are off-line, or inactive for whatever reason.
It is used as energy source and propulsion system. A fusion reactor brings light atoms together,
which produces heavier atoms and large amounts of energy.
The usual fuel is deuterium or normal hydrogen, which fuse to helium.
Hydrogen fusion is the energy source of stars.
Federation fusion reactors use deuterium, with helium as reaction product.
Starships have fusion reactors for auxiliary power and impulse drive
(max. cruising speed: 150,000 km/s - half light speed).
The Federation Starbase Deep Space Nine is powered by six fusion reactors, located at the base of the core section.
