Waste is pretty much not going to be enriched uranium, by definition. No one would be dumping enriched uranium in the first place... it's expensive, yo. Low-enriched uranium (suitable for burning in standard power reactors) is 3-5% U-235 Highly-enriched uranium (suitable for building bombs) is >= 20% U-235. Spent fuel is typically < 1% U-235.
