I do not think that that assertion is correct, because my understanding is that once the nuclear industry stopped building new reactors it moved into decommissioning. What we had was a period in which the entire sector was making all its money from decommissioning costs. The reason that those costs kept rising was that we had a very poor regulator which allowed a reciprocal relationship with private contractors, who brought forward all sorts of faster decommissioning timetables. That was nothing to do with what society needed or required; it was to do with the profitability of the industry. I hesitate to say that there are these red lines where society will not accept a new reactor because of decommissioning.
It is much more complicated than that. We must be careful that we are not gold-plating regulations that deliver millions of pounds to contractors unnecessarily.
