Materials with high radioactivity have a short half life and materials with low radioactivity have a long half life. So that makes the problem a bit better. Then look at the kind of stuff that they have to bury and store. It's not just the fissile material itself, it's pretty much everything that had to have had contact with it. Wikipedia mentions "steam generators, pumps, lids of reactor pressure vessels" [1] - those seem very reasonable to just dump in the ocean. I agree that material that can be used as fuel for modern reactors in the future should be kept accessible.
