Why not? Just bury it a bit deeper.
But it doesn't matter - you don't need to. Unlike bags, there is so little nuclear waste we can afford to dedicate one tiny area to it.
The entire nuclear waste of the US in the past 40 years can fit in a room 350 feet on each side. (Basically 1 city block.) That's it. That's all the space you need for the entire united states!
Maybe DOE should hire some HN experts so they'll learn how the job ought to be done? As much money as the nuclear industry has stolen from taxpayers, I think they can afford you.

But "environmentalists" stepped in and ended funding. Now we are stuck with the current situation of pretty much every power plant for themselves and storage all over the country.
You can take a landfill, put dirt over the top, and now you have parkland for people to use. It's happened to two intracity landfills within a couple of kilometers of where I live. The same can't be done with nuclear waste.
