How long can a nuclear submarine last?

Submarines can carry nuclear fuel for up to 30 years of operation. The only resource that limits time underwater is the provision of food for the crew and the maintenance of the boat. A great advantage of nuclear-powered submarines is that they don't require refueling. When one of them comes into service, enough uranium fuel will be put into service to last more than 30 years.

Nuclear submarines can operate underwater for three or four months in a row and cross oceans with ease. While some conventional submarines can withstand distance, none have comparable submarine resistance. Nuclear fuel is removed from the reactor and sent to the Naval Reactor Facility in Idaho for processing. Nor would it be impossible to deploy larger AIP-powered submarines; China has already deployed one, and France is marketing a cheaper AIP-powered version of the Barracuda-class nuclear attack submarine.

The high efficiency of nuclear energy also allows these submarines to operate at high speed for longer periods than conventional diesel-electric submarines. That's why it's often said that if you're able to successfully force a submarine to resurface, you'll have already won half the battle. At the moment, only the United Kingdom, the United States, France, Russia, China and India have nuclear-powered submarines, and only the first four know how to build them (China and India bought theirs from Russia).

The quality of construction of submarines has also generated negative headlines in several national newspapers.

Nuclear-powered submarines have traditionally maintained a decisive advantage in endurance, stealth and speed compared to cheaper diesel submarines. In the 1990s, submarines powered by independent air propulsion (AIP) technology came into operational use.

Nuclear reactor compartments are trimmed, carefully sealed and taken to an approved disposal site. However, there is reason to believe that AIP submarines can, if properly designed, swim underwater even quieter. Finally, humans need to socialize and be in touch with the outside world, so submarines must resurface to allow the crew to turn.
