Draconic Reactor

The Draconic Reactor sustains such an immensely powerful fusion reaction that outputs more power at its maximum potential than any other power generation in the game. Besides setting up 60 Laser Drills, you could use the Draconic Reactor to provide your entire server’s power needs, depending on the number of people playing. You may also find other uses for this completely absurd power output, keep in mind you are essentially creating and harnessing the power of an artificial star, so be very careful.

Despite what the Draconic Evolution Information Tablet tells you, these reactors are quite safe. As long as you follow these four steps, your reactor WILL NOT explode and consume your entire base in a catastrophic nuclear disaster.

DO NOT break any part of the reactor while it is online; this will result in a catastrophic nuclear disaster.

DO NOT connect the Energy output directly to the containment field; this will result in the containment field becoming unstable and cause a catastrophic explosion.

DO NOT let your reactor's temperature get above 8,000 degrees Celsius, as this will increase the strain on the containment field to contain the fusion reaction by ten times the amount and can easily cause a nuclear meltdown.

DO NOT let your reactor's fuel conversion rate get above 84%; this will cause the reactor to run dry, causing the chaos to become unbalanced with the Awakened Draconium Block within the fusion reaction and will cause the temperature to rise exponentially and cause a nuclear meltdown as previously stated.


A functional reactor requires at least 4 Reactor Stabilizers positioned an equal distance away from the Reactor Core such that it shares two coordinates (x, y, or z) with the core (in other words, it can be placed directly above, below, or straight out from any side). Each Stabilizer needs to be a minimum of 2 blocks away; although it's a good idea to place them as far as five blocks away — more distance means the reactor can hold more fuel. If the Stabilizers are five blocks away, the reactor will be able to hold eight cubic meters of Draconium (8 blocks). A Reactor Energy Injector should be placed below the core, although it can also be positioned above or to the side. Reactor Energy Injectors use Flux to power the reactor’s containment field, which keeps the fusion reaction in check (thus preventing an explosion).

The reactor GUI can be accessed by right-clicking one of the Reactor Stabilizers. It displays the core heat level, containment field strength, energy saturation, energy production rate, core mass, heat load, containment field load, fuel burnup rate, and fuel remaining.


Reactors can take up to 8 cubic meters of Awakened Draconium (8 blocks), and a functional reactor will produce Flux as long as there's more than 0nb of fuel inside the reactor. Fuel can be inserted or removed via the reactor GUI, which can be accessed by right-clicking on any properly placed Reactor Stabilizer. Fuel cannot be inserted or removed when the reactor is active or charging. When the reactor is running, heat is generated from the core, the load is placed on the containment field, and Flux is produced. Since the containment field is indirectly powered via the Reactor Energy Injector, it's essential to maintain a constant supply of power to the injector.

The energy output, the load placed on the containment field, and the fuel usage rate are directly dependent on the heat of the reactor, which rises as more energy is drawn from the reactor. If the heat increases above 8000 degrees, the reactor’s load increases exponentially in relation to the heat level. Generally speaking, reactors operating at a greater temperature than 8000 degrees will destabilise and explode. If they don't, the energy quantity required to sustain the containment field will quickly become extremely large, thus rendering the reactor highly inefficient.

Before a reactor can produce Flux, it requires an initial supply of energy to kick-start the reaction. This can be taken from any good power source and must be routed into the Injector. To initiate the charging process, press the blue power button labelled "Charge". The core will slowly change colour from orange to dark blue, and the reactor's internal energy buffer (titled "Energy Saturation" in the GUI) and the Containment Field buffer will fill. The process will be complete when it reaches 50%. Cutting the power supply to the Injector during charging will not cause an explosion, although it will stop the saturation bar from filling. Breaking the core at any point during operation or charging will cause an explosion.

Once a reactor is charged, the GUI will include a green power button labelled "Activate". Pressing this will start the reactor, and it will begin producing Flux. The load will be placed on the containment field, which requires a constant stream of power that comes directly from the energy saturation of the reactor (which in turn comes from the Reactor Injector). If the containment field does not constantly receive enough energy to offset the load, its protection percentage will, depending on how great the energy deficit is, decrease. When it reaches 0, the reactor will be fully uncontained and will explode.

Flux can be drawn from an operational reactor by connecting a Fluxduct or similar device to the back of a Reactor Stabilizer. Any power extracted comes directly from the reactor's internal buffer. Thus, if Flux is removed faster than the reactor is producing it, the internal buffer will gradually decrease. This means that drawing power too quickly will eventually result in an explosion since the inner buffer powers the containment field. Because of this, it's necessary to either use low-tier Fluxduct transfer RF slowly, or, if higher RF transfer values than 32,000/t are desired, a Flux Gate connected to Cryo-Stabilized Fluxduct. However, directly connecting the reactor's output to the Energy Injector using Cryo-Stabilized Fluxduct without a power regulator will very rapidly result in a large explosion. This is because the Cryo-Fluxduct does not have an RF/t transfer limit, so all the power from the reactor is drained at once.

An online reactor will also have a "Shutdown" button inside its GUI. Shutting down a reactor will, after a period, cause it to lose all of its charge (the charging process must be repeated in order to bring it online again). Typically, the shutdown process does not occur fast enough to prevent an explosion in the event that a reactor begins losing its containment field. However, it's necessary to shut down a reactor in order to extract or insert fuel or if one wants to remove the core safely.

Safety First

Before powering on the reactor, some additional safety features are probably a good idea. The Reactor doesn't have a concept of "limits" and will give or take as much RF as it can. This will create an unstable reactor, and eventually, an explosion. It's a good idea to use a couple of Flux Gates, which limits how much RF/t can flow through it. It is also adjustable with a Redstone signal. Therefore it may be a good idea to place a Potentiometer on each one. The Flux Gate is directional, with the side with the purple square being the input and the side with the orange square being the output. Place one Flux Gate with its Purple side on the back of one of the Stabilizers, then place a second Flux Gate with its Orange side facing the bottom of the Energy Injector. This allows you to control how much RF/t is going out of and into the reactor, respectively.

Besides this, another way you can stay safe is to place it 50 blocks or more above the landscape. This will make it where, if it explodes, it will destroy all your equipment used to keep your reactor stable as it would in both cases, but it won't devastate your base, and it won't spawn a ton of lava! That's a fair trade to me! You could also use dislocator receptacles in order to easily get from the reactor to the ground and vice versa.

Powering UP

Now that you have a fully built Draconic Reactor, we need to insert fuel. The Draconic Reactor runs off of Awakened Draconium Blocks and can hold up to 8 blocks of fuel. Once you put in the fuel, you may have noticed the core grew in size. This is a hint that you need to have the proper space for the core. Otherwise, it will not be stabilised properly. If it can't be stabilised properly, the reactor will explode.

Before we power it up, it's worth noting some minor information about the GUI. The leftmost bar displays the core temperature. Once this is past 2000C, the reactor will explode if you break any part of it. The bar on the middle right displays energy saturation; you do not want this to be 0 while the Reactor is on, as it will be trying to generate infinite RF/t and explode.

Now that the Reactor is loaded with fuel, we can hit the button on the bottom right called "Charge Reactor". Once this is pressed, the Reactor now needs a great deal of RF in order to charge up. This has to be inserted through the Energy Injector. If you followed the section on "Safety First", you can adjust the Flux Gate to allow more RF/t to flow into the Reactor. Once the Reactor has charged up its Containment Field (the middle left bar) to 50%, Energy Saturation (the middle right bar) to 50%, and it's Temperature (the far left bar) to 2000C, the reactor can be activated. It is recommended that you read the section "Keeping it Stable" before activating the Reactor. Once it's on, RF is extracted through the Stabilizers and injected through the Energy Injector.

Note that the Energy Injector can consume virtually infinite RF/t and use the Energy consumed in one tick to either charge its Containment Field, its Saturation, or heat itself. This means that if you connect the Energy Injector to a Power source capable of supplying infinite RF/t (such as an Energy Core), it will drain it completely in one tick without even beginning to charge the Energy Saturation.

Keeping it Stable

The last thing anybody wants is their base turning into a nuclear wasteland from an unbalanced Draconic Reactor. This requires understanding the GUI and the numbers behind it all, quite literally. Press the "Stats" button, and the middle of the GUI will display a bunch of numbers about the Reactor. Combined with the 4 bars, this gives you all the information you need to know about your reactor to keep it from blowing up.

First, let's start with the most important numbers. The Containment Field is the one thing keeping the Reactor from vaporising you and the surrounding land into nothing. It is represented by the middle left bar and the Field Load Rate. The stronger the Containment Field is, the more RF/t you need to keep it at that level. The Field Load Rate tells us the current RF/t we need to inject into the Reactor via the Energy Injector in order to keep it at the level it's currently at. There is no limit to how high or low you can make the Containment Field, but you need to make sure it stays above 0%. The lower the level of the Containment Field, the less RF/t it uses and the more efficient your reactor become, but it also reduces the wiggle room on the output.

The second most important thing about the Reactor is Temperature. The more energy you draw from the Reactor, the hotter it becomes, producing more energy. This is represented by the far left bar and the "Temperature Load Factor" number. Hotter is better, as it means your reactor will use less fuel. However, if it goes above 8000C, the Temperature Load Factor begins to go up at an exponential rate. This means it puts more and more stress on the Containment Field the hotter it gets. This is bad news, so the optimum temperature for running your Reactor is 8000C. Additionally, if the Temperature drops below 2000C, the reaction becomes too cold to work anymore, so the Reactor simply shuts down. Additionally, you cannot break any blocks of the Reactor unless the Temperature is below 2000C.

The third more important aspect is Generation Rate and Energy Saturation, which is represented by the middle-right bar. When you pull RF from the Reactor, you are actually taking it from its saturation. The Reaction then speeds up to try and replace this missing energy. How much energy the Reactor is producing is represented by the Generation Rate. The higher the Saturation, the lower the Generation Rate. Additionally, the higher the Generation Rate, the higher the temperature of the reaction goes.

Fourth and finally, there's Fuel Consumption. This is represented by the far-right bar or Fuel Conversion Level, Fuel Conversion Rate, and Core Mass. Core Mass is how much fuel you initially loaded into the Reactor Core. It doesn't change at all unless you insert or extract fuel and byproducts. Fuel Conversion Level tells you how much fuel you have left or how much fuel has been converted into chaos. Finally, Fuel Conversion Rate is the most important number here. It tells you how much fuel is being spent per tick on keeping the reaction going. A perfectly stabilised Reactor burns 0 nb/t. The longer the Reactor stays at specific power output, the more the temperature rises, meaning the more RF/t gets generated. Since it's a constant output, the excess goes into the Saturation, lowering the Generated RF/t. This reduces the Fuel Conversion Rate and means that the longer the Reactor stays balanced, the longer it lasts without refuelling.
