You jest, but long term nuclear waste storage really is a problem. The public at-large tends to get all NIMBY about it. In the 1980’s, the federal government was working on a long term underground storage facility in rural Nevada, near the Nevada Test Site (aka in the middle of fucking nowhere) and of course the locals threw a giant fit and got the project shut down. As a result, spent nuclear fuel is routinely held at naval shipyards and power plants around the country without a final destination.

Not a good enough reason to not invest in nuclear power, but a problem nonetheless.
