It seems that the Chinese are looking at using nuclear powered cargo ships to ship cheap crap to the USA.
Bad idea, and a lose, as is obvious from looking at the history of nuclear powered civilian cargo vessels, or just the numbers for the NS Savannah:
However, Savannah’s cargo space was limited to 8,500 tons of freight in 652,000 cubic feet (18,000 m³). Many of her competitors could accommodate several times as much. Her streamlined hull made loading the forward holds laborious, which became a significant disadvantage as ports became more and more automated. Her crew was a third larger than comparable oil-fired ships and received special training after completing all training requirements for conventional maritime licenses. Her operating budget included the maintenance of a separate shore organization for negotiating her port visits and a personalized shipyard facility for completing any needed repairs.
And then there is that whole Somali Pirate thing, which makes the idea of an unarmed civilian ship operating a nuclear reactor on the high seas even less attractive.
I can see al Qaeda salivating over the prospect of seizing a ship like this.
