Mostly politics. At every level, there is resistance, and motivation for politicians in congress (especially senators) to take a strong pro-coal, NIBMY to Nuclear stance. Any senator who accepts a disposal site, or new reactor site in their state is putting their career in the line. The kind of people who do that, tend not to become or stay senators. The end result is that we're just sitting it out, because we've made it prohibitively expensive (in terms of licensing, and in terms of political capital).
