How many tax subsidies finance into your average power plant?
Now that's just unfair. Long term storage costs for nuclear "waste" only exist because the government doesn't allow for the reprocessing of perfectly good fuel. If they did, we'd be more like France, where the total final long-term waste of a family of four's entire lifetime fits in a soda can. And as all the usable energy has been removed from it, it actually is waste, meaning there's no energy radiating from it and no danger from it. At which point, those costs look vastly easier to manage and all subsidies can come off with virtually no impact to costs.
Government created a problem (basically a tax) by disallowing the reuse of perfectly good fuel. It then partially solved the problem it created by generating a subsidy to offset the tax. In the meantime, good fuel is wasted, exposed, and dangerous. It's about the dumbest thing in the world, but then again, it was something our government came up with, so at least that makes some sense.
