An interesting point  : that £73 billion cost of decommissioning the extant nuclear plants: more than half is from Calder Hall. Not only is that a sunk cost (and thus makes no difference to decisions about the future) it's also something that we're never going to build again. So, again, not something that should weigh upon decisions about future actions.
