Yes, but that's not an effective argument for building new plants in the face of my critique. It's possibly an argument for delaying the decommissioning of older nuclear plants, but those decommissions are probably due to age-related safety concerns - the owners would likely prefer to keep the old plant running, if possible.

I've argued elsewhere for a flat-out ban on new domestic coal-fired plants. Coal is by far the worst safety and environmental offender. If we forced power companies onto a renewable-or-nothing path, we might see faster progress.
