US To Develop Small Modular Nuclear Reactors For Commercial Shipping

Authored by Naveen Athrappully via The Epoch Times (emphasis ours),

The United States is seeking to develop small modular nuclear reactors (SMR) for commercial vessels that would potentially bring down shipping costs, the Department of Transportation (DOT) said in a May 7 statement.

The initiative, launched by DOT Secretary Sean P. Duffy and the Maritime Administration (MARAD), has issued a Request for Information (RFI) for this purpose. An RFI is a formal document to gather preliminary information regarding a good or service from suppliers. In this specific case, the purpose of the RFI is to investigate whether the advancements in SMR technology and other developments are “usable, scalable, and can be made commercially viable,” according to the RFI published in the Federal Register on May 7.

SMRs have a power generation capacity of up to 300 megawatts, which is roughly a third of the traditionally larger nuclear power reactors. While the big reactors are typically custom-designed for a specific location, SMRs can be manufactured as pre-fabricated units and then transported and installed at any location.

MARAD is calling on industry stakeholders and innovators to help in the development of an SMR model that would revitalize the U.S. shipping industry, cut down transportation costs, and secure energy dominance, the DOT statement said.

“To successfully introduce SMRs, we must view this through a system-transition lens rather than just as a technology demonstration,” MARAD Administrator Stephen M. Carmel said.

“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 federal government is seeking inputs from the industry to advance the development of SMRs that would mostly eliminate fuel costs and minimize maintenance requirements, identify streamlined methods to deploy nuclear power across the nation’s fleets and logistical networks, integrate SMR production into American shipyards, and set up liability, inspection, and insurance frameworks on this matter.

MARAD is collaborating with the DOT, Nuclear Regulatory Commission, and the U.S. Coast Guard to support the development of SMRs.

According to the DOT, the SMR initiative advances two of President Donald Trump’s executive orders—Unleashing American Energy issued on Jan. 20, 2025, and Restoring America’s Maritime Dominance issued on April 9, 2025.

The Jan. 20 order instructed the heads of all agencies to review regulations, policies, and orders that impose “undue burden” on the identification, development, or use of domestic energy resources, including nuclear power.

The April 9 order said it is the policy of the United States to rebuild and revitalize America’s maritime industries and workforce to ensure economic prosperity and safeguard national security.

Commenting on the SMR initiative, Duffy said that “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 DOT secretary said.

SMR Concerns

Despite the potential of SMRs, there are concerns about deploying the technology.

A December 2025 study published in the Energy Research and Social Science journal highlighted that the high upfront costs of deploying SMRs could require injecting public subsidies into such programs.

“Diverting public investment into new small-scale nuclear projects may deprive communities of funding for other urgent priorities such as healthcare, education, and renewable energy alternatives,” the study said.

As for employment opportunities, “although construction and initial operation phases generate employment, these opportunities diminish over time as SMR plants typically require fewer personnel for ongoing maintenance and operation. This raises questions about whether the socio-economic benefits such projects are purported to bring are equitably distributed,” it said.

Meanwhile, big tech companies, such as Amazon and Google, have announced plans regarding the construction of SMRs or buying nuclear power from such facilities.

The U.S. military is looking at deploying microreactors, a subset of SMRs that can typically generate 20 megawatts or less of electricity, according to an April 27 statement from the Energy Information Administration (EIA).

For instance, the Army launched the Janus Program in October 2025, aimed at building microreactors, and has already selected nine potential bases to house them.

The Air Force is planning to set up its first microreactor at Alaska’s Eielson Air Force Base, while the Navy is soliciting offers to power its installations with SMRs and microreactors, the EIA said.
