Could a late Nimitz-class carrier be refueled twice?

Could a Nimitz-class A4W reactor be refueled twice, as some civilian nuclear plants exceed their design lives?

Possibly for the later ships, but only if the individual carrier's hull, machinery, and other components still justify the work.

The panel cautions that the class changed substantially across early, transitional, and later groups. Later ships may have enough remaining structural and systems life to make another refueling technically possible, whereas older units face more component-age constraints. George H. W. Bush is singled out because her planned service already reaches 2059 and she had not yet undergone her first refueling at the time of the discussion. Whether another sixteen years could be added would depend on her condition and on technology available decades from now, not merely on reactor endurance.
