The Maritime Administration is exploring how nuclear energy in small modular reactors can revolutionize the U.S. marine transportation system.
U.S. Transportation Secretary Sean Duffy recently announced the SMR initiative in an information request to private industry and developers.
“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,” Duffy noted.
These SMRs are advanced nuclear reactors able to generate up to 300 megawatts of electricity per unit, according to the International Atomic Energy Agency.
The federal government is pushing the development of SMRs through grant programs and numerous development projects to meet energy needs and modernize. The U.S. military has several projects underway to adopt commercial microreactors.
The U.S. Department of Energy outlines the benefits of SMRs as offering “small physical footprints, reduced capital investment, ability to be sited in locations not possible for larger nuclear plants, and provisions for incremental power additions.”
MARAD, under the U.S. Department of Transportation, is collaborating with the U.S. Coast Guard, the Nuclear Regulatory Commission and the DOE to develop SMRs.
“To successfully introduce SMRs, we must view this through a system-transition lens rather than just as a technology demonstration,” MARAD Administrator Stephen Carmel stated in the joint announcement with Duffy. “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.”
MARAD has issued the request for information to develop a commercially viable system-centric SMR concept with input due by Aug. 5.
It is open to projects for a single vessel or technologies that demonstrate system architecture (including liability frameworks, insurance pathways, port acceptance, workforce development) and how SMR can be integrated with deploying ships.
Implications for Logistics Industry
“MARAD views the potential introduction of SMR propulsion through a system-transition lens,” the RFI stated. “Global competitors are advancing the integration of nuclear propulsion into the broader maritime industry, including shipyards, ports, insurance regimes, and logistics networks, which places the U.S. at a strategic disadvantage in the absence of domestic SMR development.”
This initiative is likely to generate new business development with MARAD in ways to integrate SMRs into shipbuilding as well as logistics operations.
This latest DOT initiative is the latest example in how the Trump administration is trying to attract companies to invest in nuclear power projects.
