The Trump administration launches a consultation to explore small modular nuclear reactors as a revolutionary solution for powering ships, potentially disrupting global maritime fuel and manufacturing practices.
The Trump administration has moved to test whether small modular nuclear reactors could one day power commercial shipping, opening a formal industry consultation that could reshape efforts to cut fuel use and extend vessel range across the U.S. maritime sector.
On 7 May, Transportation Secretary Sean P. Duffy and the Maritime Administration launched the initiative, saying the aim is to develop a commercially viable SMR concept for deployment on ships and across the wider marine transport system. The first step is a request for information inviting shipowners, yards, technology suppliers and other stakeholders to outline the technical, regulatory and commercial hurdles that would need to be cleared.
The administration says nuclear propulsion could deliver high-power onboard energy, reduce fuel costs and maintenance, and strengthen both shipbuilding and national security. It also wants to explore how reactor manufacture might be folded into U.S. shipyards, a signal that Washington sees the issue not simply as a clean-energy experiment but as part of a broader industrial policy push.
According to the Transportation Department, MARAD is working with the U.S. Coast Guard, the Nuclear Regulatory Commission and the Department of Energy on the legal and safety questions that have long constrained civilian nuclear shipping. Those questions include liability, insurance, port access, reactor handling and the integration of nuclear-powered vessels into international regulatory regimes.
Nuclear propulsion is not new to maritime transport. It has powered naval fleets for decades, and the Department of Energy says the U.S. Navy’s nuclear propulsion programme has operated for more than 75 years. But commercial adoption has remained elusive because of high capital costs and public concern over safety. The current push comes as governments and shipowners search for lower-carbon propulsion options that can still support long-distance, high-utilisation trading patterns.
MARAD said the consultation is part of a broader effort to support U.S. maritime capability and rebuild domestic capacity at a time when China dominates global shipbuilding. Public comments on the proposal are due by 5 August 2026, and the agency says further workshops and technical sessions will follow.

Duffy announced that the Maritime Administration (MARAD) would assume oversight of deepwater port licensing from the U.S. Coast Guard. This change aims to streamline environmental reviews, accelerate license approvals, and lower domestic energy costs, thereby supporting President Trump’s energy dominance strategy. MARAD’s leadership in the Deepwater Port Program is expected to facilitate the safe utilization of the nation’s natural resources, create high-paying jobs, and reduce energy costs for American families.
