Sorry, dry casks are NOT a permanent solution, especially not for un-reprocessed waste. Unless you have a plan to replace them every hundred-ish years for 100,000+ yearshttps://twitter.com/KersevanRoberto/status/1245462593898250244 …

Is it as simple as that? Material fatigue from beta and gamma radiation exposure? Are they casks made of steel or concrete or..? It will become an issue for the UK now we have stopped aqueous reprocessing
I’m gonna go on record and say I was wrong about my initial comment. Since there is no active fission, the effect of damaging radiation is small. The NRC currently licenses them for 20 years and then give license renewals with inspections.
The NRC has suggested they could last for 100 years (Link: https://www.nrc.gov/waste/spent-fuel-storage/faqs.html …) Dry casks MAY last longer than that, but even if they end up lasting 150 years they aren’t a PERMANENT solution (without replacement).
I dont know why the usa doesn't invest even uranium-only recovery (UREX). Reducing the bulk must be worth it?
