reserving a couple of football fields means you're still wedded to making nuclear weapons - and in any case that stuff will be less radioactive than granite in 450 years anyway
There are OTHER nuclear paths which produce 1% of the waste (which will be less radioactive than granite in 300 years), solve the existing nuclear waste issue by acting as nuclear garbage disposals and make rare earth mining actually viable by consuming its primary waste product (which is a boon for other technologies)
As a nice side benefit they can also find enough fuel in coal ash slurry lakes that there's money to be made in cleaning up the hundreds of abandoned sites around the world. The TWO biggest environmental disasters in the USA lower 48 so far this century have been power station ash lake dam breaks
Did I mention they also produce prodigious amounts of helium?
