Nuclear shipping gains traction as Lloyd’s Register gathers industry leaders in Athens in International Shipping News , Shipping: Emission Possible 03/06/2026 LR’s Nuclear Roundtable highlighted the mounting interest from Governments, including the Government of Greece, and operators looking for scalable, zero-emission propulsion options. Lloyd’s Register (LR) brought together senior leaders from maritime, the nuclear industry and international regulation for a high-level roundtable at Posidonia 2026 to examine what needs to happen next to make nuclear propulsion a viable option for commercial shipping. Held on 1 June at the Athens Olympic Museum, the closed-door session gathered around 20 senior representatives from shipowners, regulators, reactor developers and industry bodies, alongside invited observers. The session was designed to move the conversation beyond theory, focusing on the practical pathways needed to enable safe and commercially viable nuclear-powered shipping. The roundtable was opened by Panos Mitrou SVP Shipping Strategy, LR, and featured an address from Karine Herviou, Deputy Director General of the International Atomic Energy Agency (IAEA) as well as a video welcome from Director General Rafael Mariano Grossi. Chaired by Mark Tipping, LR’s Power to X Director, the discussion focused on key areas where progress will determine whether nuclear can move beyond concept stage. Participants examined how regulatory frameworks can evolve to support controlled demonstration without compromising safety, how commercial models might develop to manage the high upfront costs, and where nuclear may have advantages over other zero-carbon fuel options. Contributors highlighted the absence of an established international framework tailored to civil nuclear applications at sea. At the same time, participants stressed that regulation must move in parallel with technology development, rather than waiting for mature designs to emerge. The economic case for nuclear als
