Nuclear Reactors

Nuclear Reactors

Available as soon as you've reached the Moon (late HV-early EV, or just get some titanium from aluminum gravel), nuclear reactors are a strong power source for EV and IV. The process of creating a reactor is quite complex and risks huge nuclear explosions. You are strongly advised to try all designs in a reactor planner before using them, and to encase your reactors in reinforced materials (2 layers minimum) or warded glass (thaumcraft) to prevent explosions from destroying the area. Test your reactor in creative first!

There are in general two types of reactors, power producing and breeder (for the items). For the power ones, you want the greatest efficiency (fewer rods, more power) and for breeders, you just want to consume as many rods as you can as fast as possible. Stacking also comes into play for large numbers, since they are not conveniently designed for that normally.

For items, you can look at this handy chart. Note that some items were excluded (for example getting thorium back from thorium rods). Note that the EU and Heat #s are for single rods (EU is /t, heat is /s as they only outputs each second), and that the EU should be multiplied by 10 for the actual amount per tick. See the planner for more details (make sure to grab 2.4.2+). Any rod that has the same heat values is equivalent in a planner design, and anything that produces less heat can also be substituted, unless it's a MOX-type design. Keep in mind that while quad thorium and dual uranium have the same heat levels, this is not true when placed next to other rods.

For the power producing types, there are a couple types:

EU reactors produce raw energy directly with a 50% penalty. Use cables to transform the power into the GT type. Note that each side of a reactor is only able to output 1A of the connected cable's voltage.

Fluid reactors produce hot coolant. Use a Large Heat Exchanger to convert the Hot Coolant to HP Steam/Steam, and HP Steam Turbines/LP Steam Turbines to generate energy with very high efficiency. See the Fluid Reactors page for details.

Vacuum reactors produce EU, but rely on cooling the cells in a vacuum freezer to keep it from exploding. See the Vacuum Reactors page to find out how to use them, and also redstone automation info.

Wrench reactors are a meme, you can read about them here

There are several fuel types:

Thorium is the cheapest and easiest to obtain, obtainable in large quantities from coal ore or thorium ore found in the nether. It lasts a long time but doesn't make much power. You need to make these to get Lutetium for Americium later on.

Uranium is obtained at Mars' moons from a couple ores. It doesn't last as long as thorium, but makes more power.

MOX is obtained by mixing plutonium (from depleted uranium rods, centrifuging uranium dust, or ores on later planets) with uranium. It returns enough plutonium to sustain itself. It outputs more power the hotter the reactor is.

Naquadah and Naquadria are obtained from mid-game ores, and are generally best used in naquadah generators.

Tiberium is made with tiberium. Get this from Ross128ba, the T5 planet.

The Core is made with naquadah and tiberium. Only use it with coolant cells!

Lithium fuel rods are used to make tritium in an alternate way. Have them touch another fuel cell to change them into tritium rods.
