In a spare few minutes I took a quick look at the U.S. Center for Maritime Innovation Report: Small Modular Reactor Technologies for Maritime Applications of May 19, 2026.As near as I can figure, it focuses on two major concerns with regard to the use of SMRs in commercial ships:1. Insurance obstacles and2. Possible adverse reactions by the public to nuclear commercial ships.That is weird to me, since my major concern would be that it is taking way too long to simply build a commercial ship with an SMR as its power source.

Liberty Global Logistics (LGL) and Hyundai Glovis signed an Memorandum of Understanding (MoU) to evaluate the feasibility of developing and operating a small modular reactor (SMR)-powered Pure Car and Truck Carrier (PCTC), initially targeting service between the United States and South Korea.The MoU moves the nuclear-powered ship project beyond conceptual design toward examining the regulatory, infrastructure, technical and commercial hurdles required for actual operation. LGL will evaluate the U.S.

A nuclear-powered liquefied natural gas (LNG) carrier could cost about 2.5 times as much to build as a conventional vessel but substantially reduce fuel costs over its operating life, according to a joint study involving ABS, Blossom Energy and a global shipping company.Presented at Gastech 2026, the study assessed a 174,000-cubic-metre LNG carrier equipped with a 20-25 MWe high-temperature gas-cooled reactor being developed by Blossom Energy.The study compared the vessel's arrangement…

SNAME’s M-50 Sustainable Fuels Technology and Research panel has given itself the task to try to figure out if there actually is a preferred sustainable fuel out there.This is a massive rabbit hole effort that does not fixate on the state of the art, but instead is making an attempt to engage all engineering tools, experience, and insight to predict the optimal future.SNAME’s assumption focuses on identifying the optimal fuel that will be universally (or at least near universally) used when direct electric (a connection to the electric distribution net or batteries) cannot work.

The U.S. Department of Transportation's Maritime Administration (MARAD) and CORE POWER (US) Inc. signed an agreement to accelerate the commercial, industrial, and regulatory pathways for U.S.-flagged nuclear-powered commercial ships. Fueled by small modular reactor (SMR) technology, this first-of-its-kind partnership will advance the President's agenda to strengthen American shipping and secure energy dominance.Under the Memorandum of Cooperation, MARAD and CORE POWER will establish a collaborative framework to navigate SMR regulatory acceptance…

The U.S. Department of Transportation's Maritime Administration (MARAD) and CORE POWER (US) Inc. signed an agreement to accelerate the commercial, industrial, and regulatory pathways for U.S.-flagged nuclear-powered commercial ships. Fueled by small modular reactor (SMR) technology, this first-of-its-kind partnership will advance the President Trump's agenda to strengthen American shipping and secure energy dominance."President Trump has made it clear that American energy dominance and maritime strength go hand in hand," said Maritime Administrator Stephen M. Carmel.

U.S. Secretary of Transportation Sean P. Duffy was joined by Maritime Administrator (MARAD) Stephen M. Carmel, U.S. Representative Michael Cloud (TX-27) and leaders from Texas’ Port of Corpus Christi to kick off a new partnership focused on small modular reactor (SMR) technology for maritime applications. By testing the latest innovations in SMRs, the Department can help revitalize U.S. shipbuilding, cut fuel costs, and restore America’s maritime dominance.This is the second agreement the Department has signed since Secretary Duffy launched the SMR initiative in May.

Looking back at history one could argue that it was French author Jules Verne in his book “20,000 Leagues Under the Sea”, published in 1869, who was speculating about a new power source much in the same out of the box thinking that H.G. Wells employed when he wrote about inter-planetary flight in “War of the World’s. Verne was writing about “electricity” from batteries using seawater which he created after studying the model of the newly developed French Navy submarine “Plongeur” at the Exposition of 1867.In the novel…

A new joint study using the Port of Rotterdam as a case study “Enabling Nuclear-Powered Feeder Ships: A Joint Development Project on Port Call Feasibility and Regulatory Pathways” has found that existing port safety and risk-management frameworks could provide a credible starting point for assessing nuclear-powered commercial ship calls within a major European port environment.The desktop study, carried out through a joint development project involving Lloyd’s Register, the Port of Rotterdam Authority, CORE POWER and A.P.

ABS issued approval in principle (AIP) for the integration of a nuclear reactor into a cargo vessel propulsion system developed by the Massachusetts Institute of Technology (MIT), HD Korea Shipbuilding & Offshore Engineering (HD KSOE) and Capital Maritime Group.This design uses a special synthetic fluid to carry heat from the reactor core. Today’s designs typically focus on micro-scale thermal outputs of 10 to 20 megawatts. The MIT design’s near-atmospheric operating pressure can allow for thinner…

ABS announced the release of the ABS Nuclear-Ready Notation, an industry first classification notation for marine and offshore assets designed to support future conversion to nuclear energy.The notation is featured in the latest ABS document, the Guide for Nuclear Ready Applications for Marine and Offshore.The notation offers a practical mechanism to help with preserving long-term flexibility, reducing the risk of major redesign later in an asset's life cycle, and demonstrating that future nuclear conversion has been addressed in accordance with ABS requirements.

With demonstration projects now underway, including a nuclear-powered LNG tanker and an offshore vessel, the debate is shifting from whether nuclear shipping is possible to how it can be delivered. Jan Emblemsvåg, Professor at the Norwegian University of Science & Technology (NTNU)'s Department of Ocean Operations and Civil Engineering in Ålesund, argues that the key barriers are no longer technical, but regulatory, commercial and political.Nuclear propulsion is returning to the…

Introduction. Looking back at history one could argue that it was French author Jules Verne in his book “20,000 Leagues Under the Sea”, published in 1869, who was speculating about a new power source much in the same out of the box thinking that H.G. Wells employed when he wrote about inter-planetary flight in “War of the World’s.
