The U.S. Department of Transportation (US DOT) has launched a new initiative aimed at developing small modular nuclear reactors for commercial shipping.
This project is part of the Trump administration’s aim to expand domestic shipbuilding and reduce operating costs across the maritime sector.
The Maritime Administration (MARAD) has issued a Request for Information (RFI) seeking proposals and technical feedback from shipping companies, reactor developers, shipbuilders and other stakeholders. The process is intended to support the creation of a commercially viable nuclear-powered shipping model in the United States.
U.S. Transportation Secretary Sean P. Duffy said:Under President Trump’s leadership, the U.S. is reclaiming its rightful place as a global sea power. To secure this future for America’s shipbuilding industry, we need to innovate. By partnering with industry experts and outside-the-box thinkers to develop a strong SMR model, we will deliver a state-of-the-art energy source that cuts costs and bolsters national security—all at the Speed of Trump.
The initiative is centred on several objectives, including improving the operational range and speed of vessels, lowering long-term fuel and maintenance costs, and strengthening domestic supply chains linked to maritime transport and energy production.
The programme is intended to support workforce development in U.S. shipyards by establishing new training pathways and credential standards connected to nuclear-powered vessel construction and maintenance.
In addition to technical development, the initiative will examine regulatory and insurance frameworks required for nuclear-powered commercial ships to access ports and operate within international shipping systems.
MARAD Administrator Stephen M. Carmel said:To successfully introduce SMRs, we must view this through a system-transition lens rather than just as a technology demonstration. We are seeking critical insights on how the government can help reduce systemic uncertainty, align regulatory structures, and enable the market conditions necessary for private capital and operators to scale these groundbreaking technologies.
The Maritime Administration is working with the U.S. Coast Guard, the Nuclear Regulatory Commission and the Department of Energy as part of the project.
MARAD plans to gather additional feedback through public workshops, technical discussions and listening sessions. Public comments on the Request for Information are due by 5 August 2026.
