What does ”uninsurable” mean? If nuclear power plants are uninsurable Silicon Valley is uninsurable.
Silicon Valley is insurance because the liability exposure is substantially less.
It is easy to bring up problem after problem with alternatives. It is not easy to show why the status quo is somehow better, because it is not.
A death is a death. Someone dieing because they fell off a roof is equally as bad as dieing due to radiation.
I do support an alternative solution: making rooftop installs safer, and more utility scale ground mount solar. Both are infinitely more tractable as problems than properly managed nuclear power. The US is already on track to install more utility scale solar this year (~150GW) than total existing nuclear generating capacity, even accounting for capacity factor. One year!
