The US-built NS Savannah, completed in 1962, was primarily a demonstration of civil nuclear power and was too small and expensive to operate economically as a merchant ship. … As of 2021, it is the only nuclear-powered merchant ship in service. Civilian nuclear ships suffer from the costs of specialized infrastructure.
Are there any nuclear powered ships?
Currently, the U.S. has 83 nuclear-powered ships: 72 submarines, 10 aircraft carriers and one research vessel. These NPWs make up about forty percent of major U.S. naval combatants, and they visit over 150 ports in over 50 countries, including approximately 70 ports in the U.S. and three in Japan.
What was the first nuclear powered civilian ship?

What would happen if a US aircraft carrier was sunk?
The sinking of a U.S. aircraft carrier might well result in casualties that would exceed the total losses of the Iraq War in no more than a few minutes. When capital ships sink, they sometimes take nearly every crew member with them; 1415 of a crew of 1418 went down with HMS Hood in 1941, for example.
Do US carriers carry nuclear weapons?

Can a nuclear aircraft carrier power a city?
The carrier can power 12000 houses and that is a small city. If the steam plant of an amphib or a carrier were modified to increase electrical generation to match propulsion power, many more houses could be powered, equivalent to a medium city based on population only.

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. Large enough waves can cause a submarine to be pulled (sucked) up to the surface.
Why do cruise ships not use nuclear power?
The largest vehicles in the world emit the most pollution. A cruise ship is equal to a million cars a day. The cargo ships and oil tankers are already a threat to the environment just by their cargo let alone their pollution.
Can a storm sink an aircraft carrier?
“A Nimitz class CVN (and the new Gerald R Ford) carrier can withstand severe damage, but its escorts (except the SSN Subs) would easily get wiped out if a CAT 3-5 storm was on the horizon.
