Uranium Waste is a radioactive byproduct of Nuclear Power Plants created by burning Uranium Fuel Rods. It is one of the few items that cannot be discarded with the trash button in containers or the inventory, giving a message that "Nuclear waste cannot be destroyed. FICSIT does not waste." Through a couple of steps Uranium Waste can be reprocessed into Plutonium Fuel Rods and then it can be used as power or Sinked. A single Nuclear Power Plant will produce 50 barrels of Waste every 300 seconds
