This is not the first we heard of something like that.
The us navy has a project to create jet fuel from seawater:

The benefits for an aircraft carrier which has virtually unlimited supply of energy and only limited space to store jet fuel is obvious.
Wikipedia states that a nuclear aircraft carrier would function for upto 25 years until it's nuclear power plant dies.
(lets say 12 years remaining until next overhaul is needed).
The implications for tw2k scenario is immense.
What i'm not sure is why would there be any nuclear aircraft carriers left after the war. They are prime targets who can't really be defended in a full blown nuclear war scenario.
