Within the past month, the Nuclear Regulatory Commission has signed memorandums of understanding to increase its cooperation with two U.S. maritime organizations. In late June, the NRC signed an MOU with the U.S. Coast Guard to strengthen coordination on civilian maritime nuclear projects, including floating nuclear power plants and civilian nuclear propulsion. On July 21, the NRC signed an MOU with the newly formed Marine Minerals Administration (MMA) to improve cooperation regarding potential future nuclear projects on the Outer Continental Shelf.

The International Atomic Energy Agency intends to launch a new initiative at the IAEA ministerial in Washington, D.C. on August 26–27. The objective of the initiative, called Atomic Technologies Licensed for Applications at Sea (ATLAS), is to provide support for “the maritime industry’s exploration of small modular reactors (SMRs) to power civilian ships and to provide offshore energy.” The IAEA hopes that this initiative will help advance the maritime deployment of such reactors.

The Department of Transportation has announced an initiative to develop small modular reactors for commercial shipping. The U.S. Maritime Administration (MARAD) has launched a request for information (RFI) seeking industry input on the development of “a U.S.-built scalable, repeatable, commercially viable, system-centric, small modular reactor and their deployment within the marine transportation system.”

London-based professional services organization and maritime classification society Lloyd’s Register has brought together a group of experts from the U.K. nuclear, maritime, insurance, and regulatory sectors with the primary goal of establishing international standards “for safe, secure, and commercially viable nuclear-powered ships.”

This Maritime Nuclear Consortium includes Lloyd’s Register as the group’s lead, safety administrator, and secretariat; Rolls-Royce, specializing in advanced reactor design; Babcock International Group (ship design, construction, and support); Global Nuclear Security Partners (security and safeguards); Stephenson Harwood (legal and regulatory issues); and NorthStandard (insurance).

Idaho National Laboratory has announced the creation of the first batch of enriched uranium chloride fuel salt for the Molten Chloride Reactor Experiment (MCRE). INL said that its fuel production team delivered the first fuel salt batch at the end of September, and it intends to produce four additional batches by March 2026. MCRE will require a total of 72–75 batches of fuel salt for the reactor to go critical.

The American Nuclear Society’s Nuclear Nonproliferation Policy Division (NNPD) held a webinar recently exploring the security aspects of floating and offshore nuclear power.

Moderator Shikha Prasad, CEO of Srijan LLC and immediate past chair of the NNPD, began the discussion by recapping the recent exponential growth in the field and its future economic potential before introducing the presenters, each of whom spoke about the work they and their organizations are doing to advance the field.

Below are brief summaries of each speaker’s presentation. To see their thoughts and the ensuing Q&A, click here.

The Boston-based Deon Policy Institute has published a white paper that examines the applications of nuclear energy in the maritime sector—specifically, floating nuclear power plants and nuclear propulsion for commercial vessels. Topics covered include available technologies, preliminary cost estimates, and a status update on the regulatory framework.

Unique opportunity: The paper points out that nuclear energy has the potential to benefit the shipping industry with high energy efficiency, lower operating costs, and zero carbon emissions. The report has a special focus on Greece, a nation that controls about 20 percent of the global commercial fleet and thus has an opportunity to take a leading role in the transition to nuclear-powered shipping.
