Fair comment, but in the UK we've screwed up nuclear for generations. Our old Magnoz reactors have a century long decommissioning period, and even in the 1960s were more expensive than coal. More modern reactors may differ, but Magnox set up the arguments for anti-nuclear advocates.
More recently, we (stupidly) accepted an abominable price for energy from Hinckley C, and indemnified the operators (including EDF if memory serves) against the cost of decommissioning.
There's evidently a good way to do nuclear, but Britain doesn't do it. We are inept, so our ROI is lower than yours. It is a great shame.
Hi, I'm French, I know a thing or two about how valuable the ROI on Nuclear is.
