As part of the MEET 2050 lecture series, I had the pleasure of presenting on the legal perspectives of civil maritime nuclear energy — an emerging topic at the intersection of the energy and maritime transitions.
In view of the challenges posed by the decarbonization of maritime transport and the pursuit of energy autonomy for certain coastal or remote regions, several States and industrial stakeholders are now considering the use of nuclear power at sea through two main applications:
- Nuclear-powered vessels (NPVs);
- Floating nuclear power plants (FNPPs).
However, this development raises significant legal questions that have so far received limited attention:
- What international regulatory framework applies to these hybrid units, which function both as ships and as nuclear installations?
- How can safety, liability, environmental protection, and international oversight be ensured for such facilities?
- What coordination mechanisms should exist between the relevant organizations (IMO, IAEA, coastal States, flag States)?
The presentation provided a structured overview of applicable international instruments (SOLAS, MARPOL, Nuclear Safety Code, nuclear liability conventions), identified current gaps, and discussed recent work carried out within the IMO aimed at revising the Safety Code for Nuclear Merchant Ships.
This issue, lying at the crossroads of maritime law, nuclear law, and international law (environmental protection, non-proliferation, etc.), deserves particular attention in order to support innovation without undermining legal certainty or public trust.
