The UK is well positioned to lead the safe development and deployment of new nuclear power systems for commercial ships and Floating Nuclear Power Plants (FNPPs), according to a new report from CORE POWER, NorthStandard and Lloyd’s Register (LR).
Technology company CORE POWER, global marine insurer NorthStandard and maritime professional services provider LR have jointly published Advanced Maritime Nuclear: A unique opportunity for the UK.
Deployment of small nuclear reactors
The new paper sets out a policy framework for the UK Government to support the deployment
The new paper sets out a policy framework for the UK Government to support the deployment of advanced small nuclear reactors on commercial ships and FNPPs.
The Department for Transport should include nuclear-powered shipping and FNPPs in an updated Clean Maritime Plan (CMP) and long-term nuclear strategy, the report argues.
Net zero by around 2050
Global shipping currently depends on fossil fuels for close to 99% of its energy consumption, but the International Maritime Organization (IMO) is aiming for its greenhouse gas (GHG) emissions to reach net zero by around 2050.
However, alternative fuel options (including biodiesel, methanol, hydrogen and ammonia) face major cost, production, transportation and use challenges.
Development of nuclear-powered shipping
In the foreword to the paper, Lord Mountevans comments: “The UK has the skills, expertise, and history of innovation to lead the development of nuclear-powered shipping."
"By leveraging our decades of experience with small reactors for the Royal Navy, we can decarbonise maritime transport, create jobs, and strengthen Britain’s position as a clean energy world power.”
Advanced nuclear technologies in modular designs
The Civil Nuclear Roadmap to 2050, published by the last government, envisaged nuclear technologies
The UK pledged to triple nuclear energy generation capacity at COP 28. The Civil Nuclear Roadmap to 2050, published by the last government, envisaged nuclear technologies, from Advanced Small Modular Reactors (A-SMRs) to large-scale nuclear plants as part of the UK’s energy mix.
These new, safe and advanced nuclear technologies in modular designs, which allow for straightforward manufacturing and regulatory approval processes that enable dramatic energy efficiency gains for global shipping.
Future nuclear operations
NorthStandard’s participation in the new paper reflects the role commercial insurability will play in future nuclear operations in the civil maritime space, particularly to cover shipowners’ liability.
Paul Jennings, Managing Director, NorthStandard, commented: “The ability to commercially insure nuclear-propelled ships will be vital to the success of bringing nuclear to maritime. It is important that governments understand the need for a civil marine nuclear liability convention within the framework of IMO and work towards creating an appropriate liability regime.”
Shore power and expensive connections
FNPPs used to alleviate the issues surrounding shore power and expensive connections
With the right investments and policies, the UK can develop a multi-billion-pound industry according to the report. In addition to zero pollution, nuclear-powered ships would not rely on shore power in port and could even feed electricity into the grid.
FNPPs could also be used to alleviate the issues surrounding shore power and expensive connections to the UK national grid.
Energy effectiveness of shipping
CORE POWER’s founder and CEO, Mikal Bøe, said: "History has shown that there has never been a great naval power that wasn't also a great maritime power. Maritime nuclear is the catalyst that can reverse the trajectory of the British shipping sector, creating unique competition to Chinese shipbuilding and ocean transport."
"The UK has been at the centre of global shipping for centuries, and this report reinforces that maritime nuclear power is not only necessary to improve the energy effectiveness of shipping dramatically but also a £2.5 trillion economic opportunity. Over time, the cost of inaction will far outweigh the cost of being the champion in this rapidly emerging market.”
Modern reactor designs and needs
CORE POWER, NorthStandard and LR aim to expand potential role for safe nuclear technology
Commenting on the launch of the research paper, Andy McKeran, LR’s Chief Commercial Officer, said: "As nuclear technology advances toward maritime applications including Floating Nuclear Power Plants, global regulatory alignment is crucial."
"Existing frameworks must be updated to reflect modern reactor designs and operational needs."
Safe and sustainable nuclear technology
McKeran added: "The UK has the expertise to lead these efforts at the International Maritime Organization (IMO) and with the International Atomic Energy Agency (IAEA), setting the foundation for safe, insurable, and scalable nuclear-powered shipping."
Together, CORE POWER, NorthStandard and LR aim to expand on the potential role for safe and sustainable nuclear technology within the maritime industry at the next London International Shipping Week (LISW) in September 2025.
