US Pushes Nuclear-Powered Ships With New Modular Reactor Initiative

The US Department of Transportation’s Maritime Administration has launched an initiative to develop small modular reactors (SMRs) for commercial shipping. The move aims to cut costs, strengthen national security, and reduce reliance on traditional fuels. A Request for Information (RFI) has been issued to gather industry input by 5 August. The RFI seeks to explore whether current SMR technology is practical, scalable, and commercially viable. It also examines how these reactors could integrate with international regulations. The goal is to create a model that revitalises US shipbuilding while securing energy independence.

The initiative focuses on deploying high-power, reliable energy sources for ships, enabling them to travel further and faster without fuel costs. Officials are also looking into embedding SMR production within US shipyards. Additionally, the RFI addresses the need for liability frameworks, insurance standards, and inspection protocols to ensure smooth port operations. Stephen Carmel of the Maritime Administration stressed that introducing SMRs should be treated as a full system transition, not just a technology test. The agency is working alongside the US Coast Guard, the Nuclear Regulatory Commission, and the Department of Energy to support the project. US Transportation Secretary Sean Duffy described the effort as a way to 'deliver a state-of-the-art energy source that cuts costs and bolsters national security'.

The Maritime Administration’s RFI remains open for public and industry feedback until 5 August. If successful, the adoption of SMRs could transform commercial shipping by reducing operational expenses and enhancing energy security. The collaboration between multiple federal agencies highlights the project’s strategic importance.
