The paper emphasizes the UK’s expertise in nuclear technology and maritime innovation as key assets that can propel the nation towards sustainable shipping practices. With the International Maritime Organization targeting net-zero greenhouse gas emissions from shipping by 2050, innovative solutions are crucial to meet ambitious climate goals while sustaining the maritime industry.
Advanced nuclear reactor technologies, including small modular reactors and Floating Nuclear Power Plants (FNPPs), are highlighted as transformative opportunities to decarbonize shipping and position the UK as a clean energy superpower. FNPPs, in particular, offer a solution to the challenge of port grid connectivity by providing clean power to ports, facilities, equipment, and visiting ships.
Titled “Advanced maritime nuclear: A unique opportunity for the UK,” the report outlines the need for immediate and coordinated government action to address regulatory, economic, and public perception barriers. It proposes a policy framework to support the deployment of advanced small nuclear reactors on commercial ships and FNPPs.
The report calls for the inclusion of nuclear power in the Department for Transport’s Clean Maritime Plan to align with advancements in nuclear technology and the IMO’s decarbonization goals. Additionally, ensuring commercial insurability for nuclear-powered ships is deemed vital for their successful integration into the civil maritime space.
Recommendations put forth in the paper include facilitating dialogue between governments and international organizations to update regulations, expanding the mandate of the Office for Nuclear Regulation to include floating nuclear applications, and supporting domestic supply chains for nuclear components and fuel.
The importance of global regulatory alignment in advancing maritime nuclear technology is emphasized, with the UK positioned to lead efforts in updating frameworks to reflect modern reactor designs and operational needs. The economic potential of maritime nuclear power is highlighted, with projections of a GBP2.5 trillion opportunity for the UK.
By hosting and supporting London International Shipping Week in September 2025, the UK government and stakeholders have a significant opportunity to drive innovation, collaboration, and the realization of maritime nuclear solutions. The report underscores the urgency and potential benefits of embracing nuclear-powered shipping to address climate goals and secure economic opportunities.
