Reactor Rod (Subnautica)

The Reactor Rod is an electronic item crafted using a Fabricator. It is used to power Nuclear Reactors. Up to four Reactor Rods can be placed in a single Nuclear Reactor. A single Reactor Rod can supply 2500 energy.

Once they are consumed, they will leave behind Depleted Reactor Rods. These must be disposed of in a Nuclear Waste Disposal.

Trivia

 * Reactor Rods have "special glass" that insulates radiation, as stated by Cory Strader.
