Reprocessing is generally expensive, poses a substantial proliferation risk, and necessitates transport of spent fuel to reprocessing plants which is way less safe than on-site storage. While it's fine for a country like France which is already a nuclear weapons state, has the wealth and technological capability to carry out reprocessing, and a strong rule of law to make sure everything is done right; for most of the world reprocessing would not be done in practice, and you wouldn't really want it to be done. Nuclear waste is simply not a problem in need of a solution.
