Uraninite Crystals are a raw material used to create a single component, the <a href="/wikis/reactor-rod">Reactor Rod</a>. They can be found both in raw form on the seabed and as a large resource deposit.

Large Resource Deposits

When harvested from Large Resource Deposits, they yield 7 - 14 Uraninite Crystals. These deposits are primarily found in:

• Blood Kelp Caves
• Inactive Lava Zone
• Inactive Lava Zone Corridor
• Lost River
• Bone Fields
• Tree Cove
• Underwater Islands

Data Bank Entry

Uraninite is a naturally occurring uranium oxide. Highly radioactive and unstable, its primary use is in the production of uranium reactor rods for nuclear generators.

Trivia

• Uraninite Crystals were formerly used to craft an intermediary material called Uranium, at a rate of three Uraninite Crystals to one Uranium. Uranium was removed in the Voice of the Deep update of 2017 to simplify the Reactor Rod recipe.
• Uraninite Crystals were previously part of the recipes for the <a href="/wikis/cyclops-shield-generator">Cyclops Shield Generator</a> and <a href="/wikis/prawn-suit-thermal-reactor">Prawn Suit Thermal Reactor</a>. In both cases the Uraninite in these recipes was replaced with <a href="/wikis/polyaniline">Polyaniline</a>.
• When picked up, the player's Geiger <a href="/wikis/counter">counter</a> will go off briefly. This is purely a cosmetic pickup sound and can never result in damage.
• The chemical formula for Uraninite Crystals (U3O8) is that of triuranium octoxide, a form very common in "yellowcake" powder. This is actually a relatively un-radioactive and extremely stable form of uranium prior to enrichment, as it is over 99% uranium-238, an isotope with a half-life of 4 billion years.
