Nuclear cruisers offered easier reactor access

Were nuclear cruisers easier to refuel than submarines or carriers?

Generally yes, because their reactor spaces were less constrained and easier to reach.

Nuclear cruisers could be easier to refuel because their reactor compartments were more accessible from above. A submarine plant sits inside a pressure hull, making major access work inherently difficult. A carrier reactor may require opening the flight deck and working down through hangar and internal deck levels. The comparison shows that refueling burden depends on the ship's architecture and access route, not simply on the presence of a naval reactor.
