Opex will always be much higher for a generation facility which requires 850 FTE specialist employees to operate (US average per plant) compared to the minimal requirements for on-site employees for utility scale solar or wind facilities. Generation tech which requires no fuel or hazardous waste handling and storage also has an obvious cost advantage. None of these factors have anything to do with “need to believe”.
I don't think I get your point. A project will not be approved and funded if the local population does not believe it is safe, so safety must be demonstrated through a variety of means, including some you mentioned. This is directly tied to the high costs involved.

> To sum up, since the early 1970s, the cost of constructing nuclear power plants in the U.S. has been steadily rising. This can be traced to a constantly shifting regulatory environment, which has continuously changed plant design requirements, and added more and more safety features, which often were required to be implemented on plants under construction. The regulatory environment is partially a reflection of the fact that nuclear power and the risks of radiation had become increasingly controversial, and that early understanding of the likelihood of a nuclear plant accident was often inadequate.
