5/5 - (595 votes)

NuclearCraft Mod is a modern physics mod made by TLJGames that aims to bring realistic nuclear, quantum, and particle physics to Minecraft. NuclearCraft has been designed from the ground up with a heavy focus on real world accuracy. NuclearCraft features over 100 unique items which can be used for power generation or as part of an in-game Nuclear Engineering system. NuclearCraft also implements many different types of machines such as the Nuke Cannon, Nuclear Reactor and Fusion Reactor. All these machines work together in order to provide players with an easy way to generate vast amounts of electricity that can then be used for powering lots of different types of electrical machines like furnaces and electric mining drills.

The foundation

Start by stockpiling all the NuclearCraft ores that you find. You’ll need a lot. You’ll also need quite a lot of
Coal and
Iron, some
Nether Quartz,
Lapis Lazuli and

Unless other power options are available to get started, your first step is to create a Decay Generator to power your early machinery. Decay Generators generate power from the heat generated by the decay of adjacent uranium and thorium blocks – they are very inefficient so you’ll want to upgrade pretty quickly.


NuclearCraft Mod

Now craft your first NuclearCraft utility machine, the Manufactory. With it, you will create Crushed Coal, Graphite Dust and Crushed Quartz, and can also be used as a simple ore doubler if you choose. The recipe is rather simple. It requires the first example of a NuclearCraft machine component: a Copper Solenoid.

At this point, consider replacing your Decay Generators with Basic Solar Panels (5 RF/t during daylight) or Uranium RTGs (4 RF/t constantly).

Now your power is a little more stable, make an Alloy Furnace. You’ll be using this machine a lot, so you might want to make more than one.

If you already have a good RF power generation setup, consider adding some Speed Upgrades to your machines.

The Isotope Separator is your next step and the most important parts of initial nuclear material processing. It separates materials into their constituent Isotopes.

Once you have your Isotope Separator set up, it is time to build your first Fission Controller, the heart of a Fission Reactor.

Building a Fission Reactor

We’re almost ready to make our first, very basic Fission Reactor, but we’re going to need a lot of Basic Plating, Tough Alloy and Steel to make one. The main article on Fission Reactors describes how to build a Fission Reactor in general, but this section will show how you may want to go about coming up with your own reactor designs. For simplicity, we will consider only a few of the the cheaper passive coolers, and also leave out the consideration of active coolers. You’ll need to decide how big a reactor to make: due to the complex nature of how Fission Reactors work, it’s not really possible to recommend a best size – you’re going to have to think carefully about your design from the get-go. As a demonstration, we will construct a small, 3×3×3 reactor using LEU-235, an entry-level fuel

Reactor Components

A basic fission reactor consists of five main components: the controller, casing, cells, moderators and coolers:

The Fission Controller is the heart of the reactor – it takes in nuclear fuel and outputs their depleted counterparts and keeps note of the reactor’s heat and power gen stats.

Reactor Casing is used to build the shell of the reactor structure. Every fission reactor consists of a cuboidal interior enveloped by a layer of casing – each side of the interior must be covered, but crucially, the edges must not be or the reactor structure will not be recognised!

The Reactor Cells hold the fission fuel while it is depleting and generating heat and power. Basically, the more cells, the more heat and power produced. Additionally, cells directly adjacent to one another or separated by at most four moderator blocks in a straight line will become more efficient and generate more power – this does come at a cost of generating more heat, though.

The moderator blocks (currently Graphite or Beryllium) are used to increase the efficiency of the reactor. For every cell adjacent to each moderator block, additional power and heat is produced, making the reactor more efficient, again at a cost of producing more heat.

The coolers are the blocks which remove excess heat from the reactor. This is very important, as a reactor that overheats will melt into a nasty mess of molten corium. There are fifteen coolers available, and as well as each having their own cooling rates, they also have their own placement rules – each cooler’s positioning must satisfy certain conditions to function, making cooling a reactor the most complex aspect of building a safe reactor.
