Today, about half the EoL reactors in the USA are on the SAFSTOR track instead of the one where they are immediately decommissioned. There is a single waste disposal site available, WIPP, that will close in the next couple of years. Only a handful of reactors on the SAFSTOR track are there because they sit adjacent to operational reactors.
So plans are one thing, reality is quite another.
