We are talking 1970. Scientists lacked the numerical models and the computing capacity to make these predictions. To accuse civilian engineers to not take into consideration recent hot topics of environmental science that lacked, at the time, rigorous models is disingenuous.
The design lifespan for those reactors was 40 years. We are extending those past lifetime because it is cheaper to do even if we need to shut them down more and more often.
The infrastructure have not adapted because it is cheaper to build a new power plant or to shutdown existing one occasionally then to adapt old existing design.

I do not understand what is your point here.
