Re: Labour... now unelectable
"12mx12mx12m pile of High Level waste and a roughly 45mx45mx45m pile of Intermediate Waste."
So that's the size of a large house and a block of flats. Not exactly tiny - and of course it all needs packing in secure containers.
"but we're really not talking about a lot of physical material here."
It's substantial once you consider breaking it up in to manageable chunks, enclosing it, and storing / cooling it.
"UK is very geologically stable, being in the middle of a plate, and it should be straightforward to find a nice big chunk of granite to entomb it in. Not politically easy, but straightforward."
Well it hasn't been found yet. See above
"The low level and Very Low Level waste is probably ideal to use to fill up a few old deep coal mines."
Yes I'm sure the locals would be delighted with that added to the water table!
Regardless of all your attempts to avoid the point, we know that cleaning up after nuclear power already costs us tens of billions...
