There seem to be efforts towards battery powered container ships out there[1], independently of any speculated use of nuclear power to charge them. Most likely they'd be battery banks in containers that get swapped out and charged at port using the same equipment as is used to load and unload cargo I believe. I remember reading that they would have more limited range and lower top speeds, but that this might not be as much of a problem as it seems because the current routes are built around large container + long haul but that's not necessarily required (for all shipping at least).
