The most serious objection is not safety but "nuclear blight", the probability that government and energy firms\’ cash, engineers and project management capacity is swept up in this great nuclear South Sea bubble and nothing is left for other renewables.
Halleluljah! Polly has actually managed to grasp an economic concept. And she\’s even grasped the correct end of the stick!
This is opportunity cost. If we decide to go down one path then we cannot use these same resources to go down another.
Of course, this applies to everything, not just nuclear: if we go down the renewables path then we face exactly the same problem. The things that we use to do that cannot be used to go down any other paths. Which means that it\’s not quite the killer argument she thinks it is. It becomes, instead, which is the best use of those resources….and I would argue that nuclear is it.
You can of course disagree with my conclusion, that\’s not a problem. As long as you\’re willing to agree that any path taken leads to exactly the same result, that we can only do one thing with the resources we have available, at least we\’ll be having the discussion about which is the best.
