A few considerations…
—————
“Temporary” dry-cask storage does NOT pose any kind of risk. Not any more than a jug of bleach. Unless you are stupid enough to drink the bleach. And it would be so many orders of magnitude more difficult, and time consuming, and labour intensive, and costly, to “get at” any of the fuel in DCS than to just chug some bleach in front of the washing machine.
A simple solution to automatically cooling wet storage is called a Stirling Engine. As things stand, most backups are diesel, but if you just wanna be able to “walk-away” there are solutions.
The solution to sites where nuclear plants have been decommissioned or removed and the DCS has been left behind, is to rebuild the nuclear plants. Those sites are ideal for new nuclear. All the original connectivity is already in place.
The discussion of military waste is not relevant to civilian energy. Here’s an idea. Don’t build nuclear weapons.
It is insane to put 90% recyclable fuel in DGS. FFS! Recycle it!
OMG! She said, ass backwards, that reprocessing fuel could power the entire US for 100 years at a cost of $100 billion. I don’t know about you, but that seems like $1 billion a year to power the whole country for a century. Um, seems like a really really low-cost. The US could just take that out of the criminal-ICE budget. GFGDCoaS!
If we just took $100 billion from Eloi Mush right now, he would still be a many-multi billionaire and everyone’s energy could be FREE for ten decades? Sounds awesome!
“Burning coal produces toxic coal ash.” Yes. And orders of magnitude more of the radioactive waste in our environment than nuclear technology. Because radioactive Carbon 14 is just dumped into the environment out chimneys of coal plants. Coal burning presents an actual radioactive waste problem.
Worrying about how a collapsed civilization would deal with our waste is a bit like worrying about whether you might have left the iron on after your house has been blown away by a hurricane.
