You must be on very cozy terms with Federation authorities to purchase this outfit legally. Beware the cheap knockoffs sold by some unscrupulous outfitters; these have a habit of melting down with very little notice. Thorium Reactors cost 4,000,000 credits. They consume 8 tons of weapon space and grant an additional unit of fuel every 10 frames. A ship may be outfitted with up to 2 Thorium Reactors. A Thorium Reactor also increases the speed and acceleration of the ship by 10 and 15 units, respectively. They can be found on Rauther in the Rautherion system, but only rarely.
