Lloyd's Register, AP Moller-Maersk and two major container ports are working together to examine what it would take to operate a nuclear-powered container ship between the United States and the United Kingdom.
The initiative, called the "Pink Corridor," brings together Lloyd's Register, Maersk, the Ports of South Carolina, and the Port of Felixstowe to study a theoretical nuclear-powered container ship route between Charleston and Felixstowe.
The program does not aim to immediately integrate a nuclear-powered ship into commercial shipping. Its goal is to examine the institutional and operational framework that would need to be in place before such a service could become feasible.
Based on a theoretical design of a nuclear-powered container ship, the study will examine port access, ship security, nuclear safety and control procedures, resilience to cyber threats, emergency response, insurance, as well as the need to harmonize maritime regulations with nuclear legislation requirements.
Nick Gross (Global Containerships Segment Director of Lloyd's Register), described the "Pink Corridor" program as an important step for the application of nuclear technology in commercial shipping.
As he pointed out, the initiative will examine, through a practical and collaborative approach, the safety and control requirements that must be met to enable the safe operation of such ships. The participation of major organizations from the maritime, port and technical certification sectors reflects the growing interest in nuclear technology as a potential solution for more sustainable shipping activity.
Nuclear technology as a direction for shipping
This initiative is part of a broader effort by the United States and the United Kingdom to explore peaceful and commercial applications of nuclear technology in shipping.
Lloyd's Register says the study is expected to support maritime development under the US-UK Technology Prosperity Deal, which includes a commitment to explore civil applications of nuclear technology in shipping and the possibility of creating a dedicated maritime corridor between the two countries.
Tom Boyle, Director of Vessel Operations and Carrier Sales for the Ports of South Carolina, noted that Charleston, as a major port on the U.S. East Coast, is looking for innovative, cost-effective and sustainable ways to transport cargo.
The theoretical design of the "Pink Corridor" allows, according to him, to study whether it is feasible to create a nuclear-powered maritime trade route.
From military to commercial nuclear propulsion
Interest in commercial nuclear propulsion is growing after decades in which the technology was used mainly in warships and icebreakers.
The Trump administration has integrated nuclear technology into shipping in a broader effort to rebuild American maritime capabilities.
The US Maritime Administration (MARAD) recently signed an agreement with nuclear technology company CORE POWER, aiming to explore a path towards developing commercial nuclear-powered ships under the US flag.
The MARAD–CORE POWER agreement addresses many of the same issues that the “Pink Corridor” faces: regulatory approval, port operations, crew qualifications, nuclear fuel and services throughout the reactor’s lifetime, insurance, and financing.
Agreements were also reached with the ports of Long Beach and Corpus Christi to explore small modular nuclear reactors and other applications of nuclear technology in shipping.
Maritime Administrator Stephen Carmel stated that the US government considers nuclear propulsion a serious commercial opportunity, but it must be treated as an integrated system: safe, secure, and economically viable, but also with the appropriate permits.
The advantages and obstacles
Nuclear propulsion could theoretically offer commercial ships extremely long range, while also eliminating carbon emissions from burning conventional fuels on board.
However, the obstacles remain significant.
Unlike conventional marine fuels, nuclear propulsion combines two particularly tightly regulated sectors, with different international rules and oversight mechanisms.
Critical issues remain open regarding:
- the licensing of nuclear reactors,
- liability in the event of a nuclear accident,
- insurance,
- the qualifications and training of the crews,
- the protection of facilities,
- nuclear waste management,
- and mainly whether ports will allow the approach of nuclear-powered commercial ships.
Another significant problem is that today there is no comprehensive international regulatory framework that governs nuclear-powered commercial ships as a whole.
The effort to create an international framework
Lloyd's Register is already working to address this gap.
Last year, it published a framework it described as the shipping industry's first analytical approach to integrating nuclear technology into commercial shipping and offshore operations.
The "Pink Corridor" is also based on an assessment of the regulatory framework carried out in 2024 by Lloyd's Register and CORE POWER.
This effort subsequently evolved into a joint development program with Maersk, aimed at examining the safety, operational and regulatory compliance requirements for advanced nuclear-powered container ships.
A plan that remains theoretical
For now, the Charleston–Felixstowe route remains entirely theoretical.
The first phase of the program aims to determine exactly what would be required to make such a sea corridor technically, institutionally and operationally feasible.
The conclusions of this phase could lead to a second stage, in which engineering, regulatory and legislative framework, safety and nuclear protection issues will be examined in more detail.
The participation, however, of Maersk, two major container ports and one of the most important international ship technical certification organizations is yet another indication that nuclear propulsion is gradually moving from the level of a theoretical discussion towards serious consideration by the commercial shipping industry.
Conclusion
The interest in nuclear propulsion does not mean that nuclear-powered merchant ships are just around the corner. It does mean, however, that shipping is beginning to systematically examine a technology that until now has remained mainly associated with naval operations and icebreakers.
The essential question is no longer just whether a nuclear reactor can safely power a merchant ship.
It is whether the entire ecosystem of international shipping — ships, ports, crews, states, legislation, safety, financing and social acceptance — is ready to welcome it.
The answer to this question will determine whether nuclear propulsion will truly be (after the failed American-Soviet efforts of the 1960-1970 period) the next great technological change in commercial shipping or will it remain, for several more years, an interesting but theoretical prospect. It is important that there is a Greek company of international shipping, with an office abroad of course, because, the bureaucratic hydrocephalus and the “support through acquaintances” system in Greece prevail over all), which company, has been engaged since 2019 in inspections of nuclear-powered ships & nuclear-cargo ships, quietly & successfully.
