How To Make Big Reactors. A basic Big Reactor is a small 3x3x3 multi-block structure. It requires at a minimum 22 Reactor casings, a Reactor Controller, an intake port to get fuel into it, an export port to get waste out, a fuel Control Rod, and a Reactor Power Tap which supplies power to whatever cable you attach to it.
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.

A nuclear reactor is constructed by placing a Nuclear Reactor block, and optionally surrounding it with up to 6 Reactor Chambers. Right-click on the reactor to access its internal inventory, which will be a grid that is 3×6 (for a single reactor block) to 9×6 (for a full 6 reactor chamber build).
Nuclear Reactor (Multiblock) This page refers to the multiblock structure, for the normal reactor please go here. Holds the equivalent of 80 fuel ingots in the internal fuel buffer and the same for the internal depleted fuel buffer. Schrabidium fuel takes 10 times as much internal capacity space, however.

What makes nuclearcraft different from other reactor mods?
Unlike Extreme Reactors, NuclearCraft takes a semi-realistic view, introducing radioactive isotopes, multi-step chemical processes for crafting and realistic nuclear fission and fusion byproducts. The consequences of mistakes are less cinematic than in other reactor mods.
How do I get Started with nuclearcraft?
Start by stockpiling all the NuclearCraft ores that you find. You’ll need a lot. You’ll also need quite a lot of Gold . Unless other power options are available to get started, your first step is to create a Decay Generator to power your early machinery.
