> most big transit projects in Canada are over budget and over schedule. As far as I understand the main reasons are that many unplanned difficulties arise because work has to be done in populated areas, creating (sometimes) huge surprises and side-effects (residents fighting against the project), and letting a contractor managing the project reveals that the gov isn't at ease. Building yourself (managing companies: Areva/Framatome then EDF all pertain to the government) a new reactor in a plant you own (without any resident nor tier-infrastructure) is a totally different matter: most burdens threatening Canadian's transit sector simply aren't there. The French reactor was planned to be delivered form 3.4 billion € and after 5 years. It will cost at least 19.9 billion € and will be at least 11 years late. I agree with your last paragraph. Delivering then exploiting without any fuss is key (the proof is in the pudding), the industry (Framatome's videos are impressive) made patent progress and the EPR in France may start in 2023: let's wait.
