As nuclear is already used on aircraft carriers, and with a major cargo ship not having a large crew including guests so it can be properly scrutinized and managed by engineers, why hasn’t this technology ever carried over for commercial operators?
Similarly for hydrogen, why (or are?) ship builders not trying to build hydrogen powered engines? Seeing the massive size of engines (and fuel) they have, could they make super-sized fuel cells and on-board synthesizing to no longer be reliant on gas?

There were 4 nuclear powered cargo ships: Savannah (US), Otto Hahn (DE), Mutsu (JP) and a Soviet/Russian one but I forgot its name. They were all too expensive to operate and they were decommissioned, save for the last one, which is also an icebreaker and it’s more useful this way.
