Plutonium

Plutonium is a highly radioactive material that can be obtained in two ways:
 * 1) Placing Metallic Uranium (see Uranium Tetrafluoride) into Atomic Reactor. Using this method you will get plutonium pretty easily but replacing LEU rods with metallic uranium will drop down the reactor's efficiency. Also, using this method, metallic uranium won't produce Used Nuclear Fuel.
 * 2) Dissolve Used Nuclear Fuel in Nitric Acid. Then add Kerosene, Tributyl Phosphate, and Hydrozene to this mixture. You will get almost pure plutonium.

Usage

 * The main component of the Atomic Bomb
 * Can be used instead of Nuclear Fuel in Atomic Reactor (Uranium is more efficient)
 * Can be placed in an Atomic Reactor with Curium to obtain Californium
