We have recent examples of construction costs going through the roof in the US: Vogtle and Summer.

Both projects were welcomed by their communities in Georgia and South Carolina. And at the state level, legislators were so enthusiastic for the projects that they passed new laws so that the costs of any overrun would get directly passed on to ratepayers, letting utilities escape financial risk for construction overruns.

I have no doubt that constructing nuclear at a new site would run into many NIMBY complaints. But most (not all) existing nuclear sites have communities that welcome the nuclear reactors, and want new ones to replace the aging ones, and ensure continuity of jobs for the community.
