Fusion Reactor (GregTech 4)

The Fusion Reactor is a multi-block EU Generator added by GregTech. It is the most advanced, complicated and expensive piece of machinery in the game. It creates Helium Plasma by fusing either Tritium or Helium-3 with Deuterium. Helium Plasma then has to be transported to Plasma Generators to generate EU. Using 3 other recipes, it can also produce Iridium Ore and Platinum Dust.

Building
The Fusion Reactor is a variable multiblock, that means that some blocks can be swapped for others, depending on the desired reaction. The Fusion Reactor needs the following blocks to operate
 * 1 Fusion Control Computer
 * 2 Fusion Material Injectors
 * 1 Fusion Material Extractor
 * 4-10 Fusion Energy Injectors
 * 32 Fusion Coils
 * 114-120 Advanced Machine Casings

The amount of Energy Injectors depends on the desired Reaction. Each Energy Injector has an internal storage of 10 million EU, so the Deuterium-Tritium reaction, which requires a starting energy of 40 million EU only needs 4 Energy Injector, while the Lithium-Tungsten requires 10 Energy Injector since it needs 100 million EU starting energy.

To start the reactor it needs 2 things. Fusion materials and enough energy. Fusion materials can be supplied into the Fusion material Injectors. Important here is that one fuel needs to be inserted into the top injector and the other into the bottom injector. Note that if you pump in cells, the cells need to be extracted as well, otherwise the reactor will stop if the cell output reaches 64 Empty cells Energy needs to be inserted into the Energy Injectors. You can check the energy level in the Fusion Control Computer.

When the reaction is running the fused materiel, Either helium plasma, iridium ore or platinum dust can be extracted from the Fusion Material Extractor. Note that the Helium Plasma is created in it's plasmatic form, and not inside cells, and thus needs to be extracted with Liquiducts or Waterproof Pipes. The plasma then needs to be transported to Plasma Generators.

Though the startup energy is only required once, the reactor still needs a constant supply of energy during the reaction. This depends on the reaction used This can easily be done by connecting 1 or 2 plasma generators directly to the Energy injectors. (note that this can't be done with the iridium or platinum recipe) Because of the high voltage Plasma Generators give, you can only use HV Cables or Superconductor Wires.
 * Tritium - Deuterium = 4,096 EU/t
 * Helium-3 - Deuterium = 2,048 EU/t
 * Wolframium - Lithium = 32,769 EU/t
 * Wolframium - Berylium = 32,768 EU/t

Reactions
The Fusion Reactor has 4 possible Reactions:

Energy yield
Both reactions have their pros and cons, though the recommended reaction is the Tritium-Deuterium Reaction.

Material yield
The advantage of creating Iridium this way above the UU-Matter way is that it costs less EU.
