Depleted Uranium is the spent fuel of the Incubator in the Ala Industrial mod. Load a uranium ingot and it buys exactly three mutation attempts; when the third is spent, the ingot settles into the ash slot as one item of ash. Four ingots therefore mean twelve attempts and four depleted pieces. No crafting grid, furnace, or blasting recipe produces this item, and nothing turns it back into fresh uranium — the ash slot of a running Incubator is its only source. Depleted Uranium stacks to 64, and automation takes it from the ash slot, which is extract-only: hoppers and pipes pull the ash out but never push items in.

The one working use for Depleted Uranium in the current release is the nuclear branch of the mutation ladder. Slot in a Creation Chip and the ash becomes an input: each attempt spends 8,000 EU — the machine's entire 8,000 EU buffer — over 1,000 ticks (50 seconds) at 8 EU per tick, trying to lift one Depleted Uranium into one Unstable Isotope. The base success chance is 25%, raised by gene bonuses but never above 95%, and in 5% of attempts the input is lost and leaves Irradiated Slag behind. The Unstable Isotope itself has no recipes yet, because rungs two and three of the nuclear ladder ship in a later release, so treat the isotope as a collection tier. Ala Industrial is an LV-tier (low voltage, up to 32 EU per tick) mod for Minecraft 26.2 (Java Edition) and runs identically on Fabric and NeoForge.
