ReactorCraft

ReactorCraft is an addon for RotaryCraft, both created by Reika. ReactorCraft adds realistic nuclear fission and fusion reactors to Minecraft. It cannot be installed properly without RotaryCraft also installed. ReactorCraft reactors expand on RotaryCraft by adding reactors that create heat, which can be used to create steam, which is used to rotate turbines, which generates power. It uses Reika's Shaft power system, which can be converted into other systems such as BuildCraft Minecraft Joules, Thermal Expansion Redstone Flux, and Universal Electricity.
