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?

I would imagine any ship carrying nuclear material would have to have all kinds of extra security onboard and probably extra ships to accompany it, which would add to the already high cost.
