Kaldor Company Fusion Plant
From Tardis Wiki, the free Doctor Who reference
The Kaldor Company Fusion Plant was the biggest power plant of its kind in Kaldor's stellar system, being the size of a small city. It housed 30,000 fusion reactors and generated enough power to fuel a yellow dwarf sun. The energy was derived from sea water and lithium, which provided the fusion materials deuterium and tritium as well as, as a byproduct, helium. Access was restricted to those with the highest security clearance and it was one of the heaviest guarded places on the planet. (AUDIO: The Sentient)
