> the main driver behind the cost increases doesn't appear to be government regulation or politics. It's all about construction and supply issues.

My understanding is that the reason construction and supply costs is so high is because we go so long between building new ones that the process has to essentially be re-invented. That nuclear does not benefit from economies of scale. One could argue that this here is coupled with government and politics given that if the approval rate is low and people fight them, then it drives the cost up. And on the other side, that's why they were so much cheaper when we first built them and why they were cheap for France. There were lots of orders and so there was a benefit from scale.
