The main hurdles for a nuclear maritime fleet are no longer establishing a reactor design, but rather regulation, liability and port access, a report from the Norwegian University of Science & Technology (NTNU) says.

Jan Emblemsvåg, professor at the NTNU’s department of ocean operations and civil engineering in Ålesund, said that with pilot projects already underway in Norway, the focus was no longer on whether nuclear propulsion is possible but rather on how it can be implemented.
