I don't think solution for storage would be a problem if politicians had more of a backbone with deciding a place for storage, and I frankly don't see a future without fossil fuels where nuclear doesn't play a key role. All of the US' nuclear waste could fit on a football field 3 meters tall. We got space for it.
As for energy security. Canada is a massive producer, and NexGen Energy is sitting on a massive deposit. Most utilities store ~4 years of material on site, and the fact it's so easily stored for many years is why Japan invested heavily in it in all those years ago. I don't think access to uranium is much of a concern.
