Nuclear Reactor (Subnautica)

The Nuclear Reactor processes Uraninite Crystal-based Reactor Rods into Energy for use by a Seabase. The Nuclear Reactor is constructed with the Habitat Builder, and can only be placed in the center of a Multipurpose Room.

The Nuclear Reactor generates energy at a rate of 250 power units per minute (4.166667 per second) regardless of how many Reactor Rods are installed. Each Reactor Rod has a capacity of 20,000 units of energy: this means that if power is constantly being drained, a Rod will last 80 minutes. Each Nuclear Reactor has 2500 energy storage. Rods are not depleted unless power is being drawn from the reactor.

A Nuclear Reactor can hold a maximum of four Reactor Rods. Once placed in the Reactor, they cannot be removed until they have been fully drained: at this point their icon will change, losing the blue glow around their midsection, and they will become "Depleted" Reactor Rods. Once removed these can be discarded, stored, or deleted from the game by placing them in a Nuclear Waste Disposal: they cannot be placed in a standard Trash Can.

If a reactor with partially expended fuel rods inside is deconstructed, the rods are lost.

Despite the Data Bank Entry saying that one should not replace the Reactor Rods without a Radiation Suit, there is no radiation risk associated with a Nuclear Reactor.

Use


Trivia

 * Originally a Nuclear Reactor only generated 60 power per minute with 500 energy storage, and Reactor Rods were only good for 1,200 energy each (around 20 minutes of use per rod at maximum power drain). This was buffed several times in later patches.
 * It was possible to construct a nuclear reactor on top of a Cyclops in older builds, but the ability to build structures on top of the Cyclops was removed due to frequent physics issues.
