Nuclear waste is tiny. It’s been stored onsite safely for half a century and never killed anyone. Why fix what ain’t broke.
Something can’t be used 60 years over usable life. Think about it.
What happened is that nuclear plants were given 40 year licenses in the US. After 40 years they applied for extensions. They were studied and it was found they had a lot more life in them. So extensions were granted. Why prematurely turn off a great carbon free generating asset that’s already been paid for. (That’d be peak German brain.)
