With Subnautica launching today, many prospective divers will find themselves lost with no way to power up their base. Fear not, for we are here to help you out.
There are four ways to generate energy in Subnautica: through internal generators such as Nuclear or Bioreactors, and external generators like Solar Panels and Thermal Plants. Of those, Nuclear Reactors are the most powerful end-game options, and often cause a small confusion over where to find the nuclear rods that power them. But don't worry -- we've got you covered.

Nuclear Reactor
Requiring 3 fragments located in the Blood Kelp Zone Trench, Sea Treader's Path, and Degasi Seabases, the Nuclear Reactor uses up to four Nuclear Rods to produce 250 power units per minute. Each Nuclear Reactor can store a maximum of 2,500 energy units, to a maximum of 10,000 energy units if four rods are equipped.
To make each Reactor Rod, you'll need:
- Uraninite Crystal
- Lead
- Titanium
- Glass
Putting all of those into a Fabricator creates a Reactor Rod, which must then be placed on the Nuclear Reactor. As the rods are consumed, they become Depleted Reactor Rods which must be taken off the Reactor and disposed of in a Nuclear Waste Disposal, which safely destroys them after a short amount of time.
Keep in mind that like virtually everything in Subnautica, Nuclear Reactors and Waste Disposal units must be unlocked by scanning wrecks and fragments scattered around the world. Both are built with the Habitat Builder, with the Nuclear Waste Disposal needing only Titanium while the Reactor requires a Plasteel Ingot, Advanced Wiring Kit, and Benzene.
That should clear up the basic doubts involving Nuclear Rods and Reactors. If you have any questions, let us know in the comments below!
