Depleted Uranium

Depleted Uranium is a refined metal in Oxygen Not Included that can be used as a building material like other refined metals. It stands out among refined metals for having the highest specific heat capacity and the lowest thermal conductivity, making it unusually good at resisting unwanted temperature changes while still serving as a metal resource.

It is also one of the best materials in the game for radiation control. As a construction material, it has 68% radiation resistance, which is the highest value among building tiles. Structures made from it can therefore shield nearby areas from radiation more effectively than most other common materials.

Although the radiation emitted by depleted uranium structures is very small, it is still useful. Tiles and buildings made from it can provide a weak source of radiation that contributes to sterilization, which makes it practical in places where a little radiation is helpful rather than harmful.

Some specific applications take advantage of this behavior:

• Depleted uranium used for tiles can provide slight radiation for sterilizing nearby spaces.
• Buildings made from it retain heat better than most refined metals because of its low thermal conductivity.
• Its high specific heat capacity makes it useful when thermal buffering matters.
• Plug Slugs can eat depleted uranium and produce hydrogen.

Because of its combination of radiation shielding and thermal properties, depleted uranium is especially useful in industrial builds, radiation-sensitive rooms, and layouts where temperature stability is important.
