1) Store the stuff above ground => risk terrorism, sabotage and "normal" accidents (e.g. lighting strike, earthquakes, corrosion leading to leaks), additionally: no one wants to live next to a nuclear dump so you won't get political support but rather fierce backlash from the people living near the chosen site
2) Store the stuff under ground => risk of collapse, of leaks and other issues as have already happened in the existing attempts

Breeder reactors IIRC have the problem of plutonium proliferation, molten-salt reactors aren't even close to being developed enough to be put into production.
