You don't need to store it for 100,000 years. Probably a few hundred. The stuff with super long half-lives isn't that dangerous. Short half-life means you get all the radiation at once. Long half life means about the same total amount of radiation, but spread out over a longer time.
Also, most of the next gen designs they're working on can reuse spent fuel from current gen reactors.
WHY NOT BOTH?
WHY NOT USE US URANIUM TO CREATE CHEAP, ABUNDANT HIGH-LOAD ENERGY INSTEAD OF LETTING HILLARY SELL IT ALL OFF TO EVERYONE ELSE?

PRETTY SURE IT WILL ALL BE SAFELY DECAYED LONG BEFORE HALF LIFE 3 COMES OUT.
