Sorry, but I’m curious about a few statements here. In what way is a reactor obsolete? And how does whatever degree of obsolescence compare with solar grids that are still undergoing massive innovation- isn’t anything we build today obsolete tomorrow? Do SMRs really take 20+ years to build?
Nuclear waste “issue” must be compared to electronic waste “issue” - with total cost of ownership calcs of rare earth mining and discarding batteries on a regular basis.
And yes, of that doesn’t address the main concern which is grid integration and base load sustainment.
Can we define “expense”? I consider the loss of public lands extremely expensive. As well as the care and feeding of the carbon based plants required to operate so the base load is maintained. I don’t know numbers, but wouldn’t such an expanse of new solar install demand huge maintenace costs - in areas increasingly prone to natural disaster?
