Even if it had never had those issues, nuclear power would still be the textbook example of a fragile system - capital-intensive, centralized projects that can be shut down by disruption to fuel shipments halfway round the world, droughts in the cooling system's water sources, or any of a dozen unions of specialized workers going on strike. Add to that iteration cycles measured in decades instead of years and it's hard to imagine how Nuclear could ever even close the gap, let alone pull ahead.
I have a theory that smart financiers avoid nuclear because getting a new version done on time and under budget is so damn hard, and smart physicists gravitate to nuclear for the same reason. I wish the nuclear-curious factions would pivot to a project Orion style endeavor instead of powering a UK hamlet sometime in the 2030s. Now there's something insanely difficult and likely to fail that I wouldn't mind my tax dollars being spent on.
