It’s a system that embodies actual complexity in a way. This definitive guide will walk you through each process with detailed explanations, tested procedures, and expert advice. At the end of this handbook, you will be adequately equipped with all that you require to construct dynamic, stable, and high-yielding. Factorio nuclear power configurations—guaranteeing that your factory will be running even at maximum capacity.

What Is Nuclear Power in Factorio

Nuclear power in Factorio is a late-game power source. Where players can generate high amounts of electricity with uranium fuel. Essentially, nuclear power in Factorio uses uranium fuel cells to heat reactors, which heat heat exchangers through the exchange of heat via specialized heat pipes. The heat exchangers convert heat to high-temperature steam, which drives steam turbines to produce electricity. One of the things you can do is, for example, Cheap Factorio Server Hosting by which you will have a seamless gaming experience.

What sets nuclear power apart is its scalability and energy density. It gets the powerful neighbor bonuses effectively doubling or quadrupling its output. This makes nuclear layouts ideal to power huge megabases or automated science outputs. There is the necessity of mining uranium ore, purifying it into U-235 and U-238, handling fuel creation, and processing spent fuel cells. To operate nuclear power efficiently and safely. Opens the door to enormous factory expansions and rocket launches without losing power.

Liberating Nuclear Power Technology

It requires a deep investment in the tech tree and advanced automation to support the complexity of the system. To begin, you’ll need to work your way through several key research milestones that unlock the tools and processes behind nuclear energy. The first technology to target is Uranium Processing. This allows you to extract uranium ore and purify it into U-235 and U-238 with the aid of centrifuges. Without it, you can’t start gathering the fuel required for nuclear power. Next comes the core tech: Nuclear Power. This unlocks essential components like the Factorio nuclear reactor, heat pipes, heat exchangers, and steam turbines.

These are the building blocks of your nuclear plant. This research requires utility science packs. A key aspect of maintaining nuclear power is obtaining sufficient U-235, which is very scarce. To address this, study the Kovarex Enrichment Process. Which transforms excess U-238 into U-235. Where you can recycle spent uranium fuel cells. These all stack on top of each other and need proper planning. Nuclear power is not merely a one-time tech advancement — it’s a complex system that develops over several stages.

Key Features

• Needs mid-game development with utility science packs.
• Unlocks nuclear reactors, turbines, and heat exchangers.
• Allows uranium mining and processing through centrifuges.
• Adds Kovarex Enrichment, where U-238 is transformed into U-235.
• Facilitates automation and energy scaling in large factories.

Mining and Processing Uranium

Uranium is the foundation of nuclear energy in Factorio. This introduces complexity early on and compels you to incorporate chem production into your mining activities. To mine uranium, position electric mining drills on uranium patches and link them with pipes containing sulfuric acid. The drills will entirely stop without a constant flow of acid. After you’ve extracted sufficient ore, the second step involves processing uranium in centrifuges. Once you collect sufficient (40 units).

You can unlock the Kovarex Enrichment Process, which enables you to create U-235 more cost-effectively using U-238. An optimized uranium mining and processing system usually comprises fluid wagons or tankers, buffer chests, inserters, and several centrifuges operating in parallel. Automation is vital — manually handling uranium becomes unfeasible once your factory gets large. Proper extraction and refinement provide a consistent amount of fuel, which keeps your reactors running continuously and your factory operating 24 hours a day, 7 days a week.

Key Features

• Needs sulfuric acid to refine uranium ore.
• Centrifuges refine uranium into U-238 and U-235.
• U-235 drives fuel cells, essential for reactor function.
• Kovarex Enrichment processes U-238 into additional U-235.
• Automation crucial for constant operation.

Nuclear Power Components

It’s a four-stage process with four large components in an exact order of operation: Nuclear Reactors, Heat Pipes, Heat Exchangers, and Steam Turbines. Each component is essential to the process of transforming uranium fuel into electricity, and knowing how they interact with each other is the key to a successful Factorio nuclear setup. The focal point is the Nuclear Reactor, which produces heat based on uranium fuel cells.

The heat is conveyed by Heat Pipes, which transport thermal energy from the reactor to Heat Exchangers. The heat exchangers convert water into high-temperature steam. Each of those sections has its own limitations, mechanics. Turbines being overloaded with a lack of steam supply cause performance to lag. Integration tips to enable you to build a stable and high-power nuclear energy system.

Nuclear Reactor

The Nuclear Reactor is the central piece of nuclear energy production in Factorio. It produces vast quantities of heat by burning uranium fuel cells, inserted manually or through automation. Every direct connection to an adjacent reactor gives a +40 MW bonus, up to 160 MW per reactor in a 2×2 configuration or larger. Fuel cells burn for 200 seconds.

No matter the bonus. Which ultimately generate the steam required to drive turbines. Utilizing steel chests and stack inserters guarantees proper fuel supply and extended reactor uptime. Nuclear reactors require an upfront investment in infrastructure and research. In addition, experience Dedicated Game Server Hosting to improve your experience in Factorio nuclear power.

Key Features

• Generates 40 MW of heat independently; this rises to 160 MW with maximum neighbor bonuses.
• Needs uranium fuel cells to function, depleted within a 200-second cycle.
• Does not produce electricity directly — produces only heat.
• 2×2 or larger compact reactor grids are the most space-efficient layout for highest output.

Heat Exchanger

Heat Exchangers are tasked with changing heat from the nuclear reactor into usable 500°C steam and piping it into steam turbines for the electricity. Each exchanger takes 103 units of heat per second to operate and uses 100 units of water per second to run at maximum efficiency. Having exchangers near the reactor prevents significant heat loss and optimizes energy conversion. Exchangers do not need power to operate — they run passively provided they are provided with sufficient heat and water.

Water may be piped from offshore pumps or fluid wagons, and should be uninterrupted and constant to prevent power fluctuations. Ultimately, heat exchangers are a crucial intermediary step between the reactor and the turbines. Enjoy user-friendly gaming hosting for best infrastructure designed specifically for Factorio. Proper planning of exchanger-to-reactor ratios and ensuring tight, efficient layouts is key to a successful nuclear setup in Factorio.

Key Features

• Burning heat to produce 500°C steam from water.
• 103 units of heat per second is needed for each exchanger to function at peak performance.
• Placement matters — exchangers should be placed as close to heat pipes as possible.
• Needs no electricity or control signals.

Steam Turbine

The Steam Turbine is the last part in the nuclear power cycle in Factorio. It sucks in 500°C steam from heat exchangers and burns it to produce electricity at an extremely efficient rate. One turbine is capable of burning up to 60 steam per second and generating 5.82 MW of power. With each exchanger generating approximately 103 steam/sec, it can drive 1.7 turbines. This makes two exchangers quite useful for powering three turbines. Provided they get proper temperature steam from the exchangers, they will automatically work.

Key Features

• Consumes 60 steam/sec to generate up to 5.82 MW of electricity.
• Must be supplied high-temperature steam (500°C) from heat exchangers to operate.
• Turbines overbuilt with insufficient steam cause underutilization.
• Which is perfect for factories in the late game.
