Where does excess uranium 238 goes?

Question

Natural uranium is 0.7% U-235 and the rest is U-238. For nuclear reactor you need enriched uranium with higher percentage of U-235. But what to do with U-238 if it’s useless as reactor fuel, as a nuclear weapon, and still radioactive to use it as regular material.

Answer 1

Deleted uranium, excess U-238, is used for artillery rounds and 25mm+ bullets, as armor for military vehicles, and I think aircraft use it as counterbalances.
