How long does a nuclear reactor last in a submarine?

Submarines may carry nuclear fuel for up to 30 years of operation. The only resource that limits the time underwater is the food supply for the crew and maintenance of the vessel.

How much power does a nuclear submarine reactor produce?

 To shift its immense weight of 100,000 tonnes, the US Navy has equipped it with two A1B nuclear reactors, each capable of producing 300 MW of electricity.

How big is a nuclear reactor on a submarine?

Reactor sizes range up to ~500 MWt (about 165 MWe) in the larger submarines and surface ships. The French Rubis-class submarines have a 48 MW reactor that needs no refueling for 30 years. The nuclear navies of the Russian Federation, the United States, and the United Kingdom rely on steam turbine propulsion.

How long would nuclear powered submarines stay underwater?

The limits on how long they can stay underwater are food and supplies. Submarines generally stock a 90-day supply of food, so they can spend three months underwater.

Can a submarine nuclear reactor explode?

This will trigger a criticality that will either explode the reactor releasing all the fuel or the criticality will melt the fuel and melt through the floor of the reactor releasing the hot fuel in the water. The explosion would be comparable to the torpedo explosion but it would spread the nuclear material.

Why do cruise ships not use nuclear power?

There are only a few companies capable of building nuclear reactors, hundreds make diesels. Cruise lines want cheap, very cheap labor, and cheap labor doesn’t, and you don’t want them to, work with nuclear reactors. You can get fuel, but is expensive and delivery,refueling all complicated.

How do submarines get air?

Oxygen is supplied either from pressurized tanks, an oxygen generator (which can form oxygen from the electrolysis of water) or some sort of “oxygen canister” that releases oxygen by a very hot chemical reaction. … The carbon dioxide is trapped in the soda lime by a chemical reaction and removed from the air.

How often do nuclear submarines refuel?

Nuclear power allowed submarines to run for about twenty years without needing to refuel. Food supplies became the only limit on a nuclear submarine’s time at sea. Since then, similar technologies have been developed to power aircraft carriers.

How fast can submarines go underwater?

There are established reports and manufacturer’s claims that would indicate two (or perhaps more) submarines are capable of speeds exceeding 30 knots (56 km/h).

Can you survive a tsunami in a submarine?

Submarines are relatively unaffected by weather or tsunamis when submerged in deep open waters. Once a submarine is deep enough the conditions on the surface are not felt. However if a submarine has to go shallow or to periscope depth then conditions on the surface become a major concern.

What happens if a submarine hits a whale?

It can be quite spectacular sometimes. It happens on rare occasions. Whales make sounds that can be heard by the submarine sonar. Submarines usually try to avoid the whales, but on the rare occasions that a collision occurs, it is the whale that suffers the worst of it.
