If you’ve ever been stuck mid-space jump with no launch fuel, or watched your base shield fizzle out during a sentinel raid, you know how critical high-power resources are in No Man’s Sky. One of the most versatile of these is uranium, which powers everything from advanced starship thrusters to hazard protection upgrades and automated base defenses. Most new players spend hours hunting for rare uranium deposits on radioactive planets, but there’s a far more consistent way to get all you need. This guide breaks down exactly how to make uranium in No Man’s Sky, no endless planet scouring required.
How to Make Uranium in No Man’s Sky via Crafting Refinement
The fastest and most reliable way to get uranium without exploring hostile planets is to refine it using common, easy-to-source resources in a medium or large refiner. Small refiners don’t support uranium crafting, so you’ll need to unlock the medium refiner first via the base building quest line, which takes roughly two hours of playtime for new players. You don’t need any rare tech or high-level upgrades to use this method, just a steady supply of base ingredients.
There are two proven refinement recipes that work for all game versions, including the latest updates. Uranium refinement recipe 1: 2 x Gamma Root + 1 x Ferrite Dust = 1 x Uranium is the most accessible for most players, since gamma root grows wild on all radioactive planets and ferrite dust can be dug up on any world with a terrain manipulator in two minutes flat. Uranium refinement recipe 2: 1 x Phosphorus + 1 x Cobalt = 1 x Uranium works well if you already have a phosphorus farm set up for other crafting projects, but it’s a bit less cost-effective for most players.
Large refiners can process 50 units of uranium per minute, which is three times faster than medium refiners, so upgrade to a large one as soon as you can if you go through a lot of uranium. You can also stack multiple refiners to process bulk batches at once, which is perfect if you’re prepping for a long expedition or stocking up for trade. I usually run four medium refiners at once when I’m gearing up for a cross-galaxy jump, and I can make 200 units of uranium in 10 minutes flat.
Farming Uranium Consistently Without Planet Exploration
If you want a fully self-sustaining uranium supply that requires almost no ongoing work, set up a small gamma root hydroponic farm at your main base. You don’t even need to build the farm on a radioactive planet, as long as you use hydroponic trays connected to a power source. You’ll never have to deal with radioactive storms or aggressive sentinels again once this farm is up and running.
To build a farm that produces enough uranium for casual play, you’ll need the following items:
- 10+ hydroponic growing trays, unlocked from the base building tech tree for 10 condensed carbon each
- At least 2 medium refiners (or 1 large refiner) to process harvests in bulk
- Gamma root seeds, which you can collect from wild gamma root plants or craft with 1 x gamma root + 1 x condensed carbon
- A reliable power source (solar panels + batteries work for most bases, or uranium itself for off-grid setups)
- Storage containers to hold extra refined uranium and raw inputs so you don’t run out mid-craft
Gamma root takes 15 minutes to grow fully, so you can harvest it every 15 minutes if you’re hanging around your base, or leave it for a few hours and come back to a full harvest. I’ve had a 12-tray gamma root farm running on my frozen home planet for six months, and it gives me enough uranium to power three bases, a full fleet of starships, and all my exocraft hazard protection without ever leaving the base. You can even expand the farm later if you start using more uranium for trade or large-scale base building projects.
How to Find Natural Uranium Deposits When You’re in a Pinch
If you need uranium right now and don’t have a refiner or farm set up yet, you can gather natural uranium from deposits on specific planet types. This method is great for quick fixes, like when you’re stuck on a planet with no launch fuel and don’t have the resources to build a refiner. It’s not as consistent as crafting, but it works in a pinch.
Natural uranium only spawns on radioactive and extreme radioactive planets, which you can spot in your star system scan by the yellow radiation icon next to their name. Always check the planet’s hazard level before landing, as extreme radioactive planets can drain your hazard protection in 30 seconds if you don’t have the right upgrades. Once you land, use your analysis visor to scan for uranium deposits, which will show up as bright green markers on your HUD.
Natural uranium deposits are almost always guarded by aggressive sentinels, so keep your multi-tool handy in case you need to fight or run. A single large deposit can give you up to 200 units of uranium, which is enough for 10 launch jumps, so it’s worth the risk if you’re stuck. But don’t rely on natural deposits long term, as you’ll end up wasting hours running from storms and sentinels that you could spend on more fun parts of the game.
Smart Uses for Uranium That Make Farming It Worthwhile
A lot of new players skip farming uranium because they think it’s only useful for niche upgrades, but it’s actually one of the most versatile high-end resources in the game. Knowing what to use it for will help you avoid wasting it on low-value tasks that can be done with cheaper resources like carbon or di-hydrogen.
The most high-value use for uranium is launch fuel for exotic and experimental starships. Many high-end ships use uranium instead of di-hydrogen for launch fuel, which lasts three times longer per jump and saves you from having to farm di-hydrogen every time you want to travel between planets. Uranium also powers base shield generators that have twice the health of carbon-powered shields, which is a lifesaver during sentinel raids or extreme weather events that can destroy unprotected bases in minutes.
If you love exploring extreme planets, uranium-powered hazard protection upgrades last 10 times longer than standard carbon versions, so you don’t have to stop and refuel every five minutes while you’re scanning for rare resources or ancient ruins. You can also sell excess uranium for a decent profit at space stations, especially in systems with no radioactive planets, where uranium sells for twice the standard galactic price. Just don’t waste it on basic fuel needs like your base life support, as that’s a huge waste of a high-value resource.
You don’t have to spend hours wandering hostile radioactive worlds to stock up on this high-value resource. Once you set up a simple refinement farm, you can make as much uranium as you need whenever you need it, with minimal ongoing effort. Whether you’re gearing up for a long interstellar expedition, fortifying your base against sentinel attacks, or stocking up for trade runs, knowing how to make uranium in No Man's Sky will make every part of your playthrough far smoother. Next time you’re low on fuel, skip the risky planet run and use your refinement setup to get what you need in minutes.
