We already have electric oceanic ships. They’re called nuclear submarines.

Allseas is putting the reactors on their vessels as well iirc.

US nuclear submarines consume highly-enriched uranium, that's nearly as (and sometimes more) pure as the weapons-grade version. That doesn't mean oceanic reactors aren't possible, it just means that military subs are a bad example.

French nuclear submarines run on 7% enriched fuel, so it's certainly possible to build military submarines that don't need HEU.

There are nuclear icebreakers.

Nuclear powered non military ships do exist, it just not economically feasible .

Russia is operating nuclear civil vessels (icebreakers) since 1957

Yep, was just lookin up their recent news on this: https://www.allseas.com/en/who-we-are/news-and-media/allseas...

While perhaps not practical for oceanic shipping as is, it's a fun exercise to demonstrate the energy density of nuclear power.
