"Impossible" might be a bit strong of a word, but recent attempts have proven that the initial estimates of time and cost are not very useful for evaluating actual time and cost of completion. And completion is not a guaranteed outcome, as ballooning costs, corruption, or market conditions can cause failure and loss of billions of dollars of labor and materials. * VC Summer in South Carolina: failed due to corruption and construction/design incompetence * Vogtle in Georgia: might finish, but every few months gets delayed more for a grab bag list of reasons. See, for example: https://thecurrentga.org/2021/12/03/construction-quality-issues-delay-plant-vogtle-nuclear-projects-again/ https://thecurrentga.org/2021/12/03/construction-quality-iss... * Flamanville in France: who knows what went wrong here * Hinkley Point C in the UK: not looking great * Olkiluoto in Finland: it finally finished and works! Yay! https://thecurrentga.org/2021/12/03/construction-quality-issues-delay-plant-vogtle-nuclear-projects-again/ https://thecurrentga.org/2021/12/03/construction-quality-iss... Even in France's first generation of building, of the same design, costs rose as they built more. Nuclear just can not seem to find its groove of being reliably constructed or planned.
