That makes no sense-a nuclear powered carrier that doesn't require underway replenishment, would be much more capable if its escorts also didn't require conventional oil fueling.
If the US had continued to build nuclear powered surface ships through the end of the cold war, then it probably wouldn't be so expensive-economies of scale, plus you'd still have the infrastructure and training pipeline there.
