> A typical dry-storage cask holds 10 tons of spent fuel and costs about $1 million–$2 million each. (The CASTOR is at the upper end of that range.) This translates to a cost of less than one-twentieth of a penny per kilowatt-hour—about 1 percent of the cost of generating nuclear power.

They last for anywhere between 30-100 years and I assume to be be processed and put into new casks after that. So "less than one-twentieth of a penny per kilowatt-hour" every 30-100 year.

Note this is for the worst of the waste. There is still low level waste and long lived waste that need not be stored in dry casks. It still doesn't sound as problematic. I think the main issue is finding a site and protecting the casks/waste.

But it is of course not only the price of buying a couple of those containers, you also need a facility to store them, you may have to move them around, you probably have to guard them, you have to monitor them, ...

Of course it isn't, but at least the CASTORS can be safely transported by train, and a processing facility is not orders of magnitude more expensive than the power plants themselves. If we could forgo the nimbyism, we already have a technical solution and a reasonable estimate of the cost now and in the next 100 years. It could easily be factored in the cost of electricity from nuclear and put in a fund for when it's needed.
