Description
Plutonium is an IndustrialCraft 2 Experimental inventory item used to craft MOX Nuclear Fuel and RTG fuel pellets for advanced energy generation. Plutonium is not mined and cannot be placed as a block: the resource is synthesized inside the nuclear fuel cycle. When a Uranium Fuel Rod is spent, run the Depleted Uranium Fuel Rod through a Thermal Centrifuge — the outputs include Uranium 238, Iron Dust, and one Tiny Pile of Plutonium; a depleted MOX rod yields whole units plus even more tiny piles. Nine Tiny Piles of Plutonium combine in a 3x3 crafting grid into a full unit, and the recipe is reversible, decomposing back into nine piles.
The first application is MOX Nuclear Fuel: three Plutonium plus six Uranium 238 in a 3x3 grid, then packed into an empty fuel rod with a Canning Machine. The second is Pellets of RTG Fuel — three Plutonium and six Dense Iron Plates — loaded into a Radioisotope Thermoelectric Generator for a steady, passive EU stream. MOX rods scale their EU/t output with reactor heat, outperforming uranium rods in a hot core. Plutonium exists only with the IndustrialCraft 2 mod, not in vanilla Minecraft.

Guide
How to get and use Plutonium in Minecraft
-
1
Install IC2 Experimental
Add IndustrialCraft 2 Experimental to a modpack; Plutonium does not exist in vanilla Minecraft.
-
2
Build a working nuclear reactor
Craft a Nuclear Reactor, place it, and prepare cooling cells, heat vents, and a power output line so the reactor can run safely.
-
3
Reprocess depleted rods in a Thermal Centrifuge
Let Uranium Fuel Rods deplete in the reactor, then run the Depleted Uranium Fuel Rod through a Thermal Centrifuge: the outputs include Uranium 238, Iron Dust, and Tiny Piles of Plutonium; depleted MOX rods yield even more.
-
4
Craft full Plutonium from Tiny Piles
Collect nine Tiny Piles of Plutonium and combine them in a 3x3 crafting grid to produce one Plutonium; the recipe is reversible if you need piles again.
-
5
Use Plutonium for MOX or RTG
Craft MOX Nuclear Fuel from three Plutonium and six Uranium 238, then pack it into an empty fuel rod with a Canning Machine, or craft RTG Pellets from three Plutonium and six Dense Iron Plates and load them into a Radioisotope Thermoelectric Generator for passive EU.
Safety tip
MOX Nuclear Fuel is highly radioactive and harms unprotected players; keep a Hazmat Suit nearby when handling fuel rods.

Frequently asked questions
Is Plutonium a placeable block in Minecraft?
No, Plutonium is an inventory item from IC2 Experimental; you cannot place it as a block, only use it in crafting recipes.
How do I get Plutonium without mining it?
Run depleted fuel rods through a Thermal Centrifuge: a depleted uranium rod yields a Tiny Pile of Plutonium, and nine tiny piles craft into one Plutonium.
How many Tiny Piles make one Plutonium?
Nine Tiny Piles of Plutonium fill a 3x3 crafting grid to produce one Plutonium, and one Plutonium decomposes back into nine Tiny Piles.
What is MOX fuel and how is Plutonium involved?
MOX Nuclear Fuel is crafted from three Plutonium and six Uranium 238; MOX rods scale their EU/t output with reactor heat, outperforming uranium rods in a hot core.
What does Plutonium do in an RTG?
Plutonium crafts into RTG Pellets that load into a Radioisotope Thermoelectric Generator, providing a constant passive EU output.
