The USS Savannah was built as a civil ship, as a demonstration. I don't think it carried passengers though. Russia has some nuclear powered ice breakers.
At this point, there are no known nuclear powered jet engines.Anyone, of course, with better information, is welcome to refine this answer.Both prototype nuclear powered jet engines ever built are stored in the EBR-1 site parking lot in Idaho and can be seen by anyone when they tour the EBR-1 reactor historical monument and museum.
The ONLY nuclear device(s) ever used in a world war was the Hiroshima & Nagasaki atomic bombs that were dropped in August of 1945, ending WWII. Nuclear powered naval ships were used in a number of other conflicts, but not nuclear weapons.

Ummm, yes the cars in your imagination are powered by milkshakes!

The Westland Wasp is a turbine powered, shipboard anti-submarine helicopter. Also a unique first generation jet helicopter made famous for being the first helicopter ever to be operated from (frigates and destroyers) and the first helicopter to disable an enemy vessel at sea. Is a naval vessel used for kits and landing in difficult areas
No
no.
Maybe Chernobyl, but only for a short time. Ever heard of SL1? Both are sad events. There are some very large coal powered plants in the USA and the rival the nuclear plants.
Who ever has nukes.
The first nuclear powered merchant vessel is the NS Savannah. She was built as a feasibility project for the potential use of nuclear energy. Only 4 civilian merchant vessels have ever been built with nuclear plants, and of those, only 1 is still operational, the Russian ship NS Sevmorput.The Savannah's design wasn't competitive with other conventional merchants, nor was intended to be. In the end, economic factors, her design issues (she couldn't hold as much cargo as her competitors, and took longer to load) training/crew issues and costs (she required a larger crew, trained also in nuclear propulsion and safety), as well as the oil crisis of the 70's, led the U.S. Maritime Administration to decommission her.She was moved to Patriots Point Naval & Maritime Museum in Charleston, S.C., in 1981 and stayed there for many years, being a notable sight for those of us who were stationed there. Her clean hull lines and design stood out at Patriot's Point as we left and entered Charleston Harbor.She's been moved here to Baltimore for full decommissioning and removal of systems. Designated a Historic Landmark, it's hoped that someone will pick her up as a museum ship, but so far no one has come forward.
Nuclear energy does NOT renew. Fusion is powered by hydrogen produced in the Big Bang. Fission is powered by heavy elements produced in supernova explosions that happened roughly 7 to 9 billion years ago, No more of these fuels will ever be available to humans than what we have now.
