U.K Firm Explores Possibility Of Mounting Small Nuclear Reactors On Ships
Our take
The exploration of small modular nuclear reactors (SMRs) for maritime applications, as undertaken by Core Power, represents a potentially transformative shift in global shipping and ocean operations. The current reliance on heavy fuel oil and, increasingly, LNG, presents significant environmental challenges, contributing to air pollution and greenhouse gas emissions. This initiative, while in its early research phase, offers a pathway toward significantly reducing that carbon footprint, aligning with the growing global pressure for decarbonization within the maritime sector. The need for cleaner energy solutions is underscored by research into the impacts of human activity on marine ecosystems, as demonstrated in studies like [No place like home: assessing the multidimensional habitat use of endangered Arabian Sea humpback whales (Megaptera novaeangliae, Borowski 1781) with satellite telemetry], which highlights the sensitivity of marine life to environmental changes. Furthermore, the increasing focus on transforming ocean data sharing, as noted in [Nigeria World Hydrography Day to Focus on Transforming Ocean Data Sharing - THISDAYLIVE], suggests a broader commitment to understanding and mitigating the impacts of human activities on the ocean.
The feasibility of SMRs onboard ships raises a complex interplay of technological, regulatory, and societal considerations. While SMRs offer advantages such as reduced size and enhanced safety features compared to traditional nuclear power plants, their application in a dynamic marine environment introduces unique engineering challenges. Maintaining reactor integrity during voyages, addressing waste management considerations in a remote context, and navigating the complex web of international maritime regulations are all critical hurdles. The environmental impact assessment of such installations, including potential risks of accidents and the long-term effects of radioactive materials, will require rigorous, peer-reviewed scrutiny. We see parallels in the considerations surrounding offshore renewable energy, where ecological impact pathways are being assessed, as explored in [Offshore floating photovoltaic: from ecological impact pathways to MSFD criteria]. The potential for SMRs to power research vessels, cargo ships, and even naval fleets presents a compelling vision, but this necessitates a phased approach grounded in verifiable data and robust safety protocols.
The integration of nuclear power into maritime operations also necessitates a shift in global collaboration and data transparency. The International Maritime Organization (IMO) and other relevant regulatory bodies will need to develop specific guidelines and standards to ensure the safe and responsible deployment of SMRs at sea. International agreements addressing liability, emergency response, and nuclear safeguards will be crucial to building trust and preventing proliferation concerns. The success of this endeavor will hinge on fostering open communication and data sharing among researchers, policymakers, and industry stakeholders. The establishment of a robust, integrated data ecosystem, a concept we champion at World Data Ocean, will be vital for monitoring reactor performance, assessing environmental impacts, and informing policy decisions. Real-time, validated data is the foundation for building confidence in this technology and ensuring its sustainable implementation.
Looking ahead, the development of SMRs for maritime use presents a pivotal moment for the shipping industry and ocean stewardship. The potential benefits – reduced emissions, increased operational efficiency, and enhanced energy security – are undeniable. However, realizing this potential requires a commitment to rigorous scientific validation, transparent regulatory frameworks, and a collaborative global approach. One key question moving forward is how effectively we can calibrate the potential advantages of SMRs against the inherent risks and the need for robust long-term ocean monitoring to detect any unforeseen ecological consequences. The coming years will be critical in determining whether this technology can truly contribute to a cleaner, more sustainable future for our oceans.
Core Power has started a research project to evaluate the possibility of installing small, modular nuclear reactors on massive ocean-going vessels, which would act as mobile power stations.
To do this, they want to use a specific reactor design called the mPower, which was made by BWX Technologies.
By building these reactors entirely inside shipyards instead of on regular land, the companies hope to avoid the massive delays, local zoning arguments, and heavy paperwork that slow down traditional, land-based power plants.
“We’re building, integrating and deploying ship-based nuclear energy systems that deliver reliable power where industry and nations need it most,” said Mikal Bøe, CEO of Core Power.
“We are focused on commercial delivery, from vessels and infrastructure to kilowatts consumed and industries powered.”
Once these power ships are built, they can be towed across the waters to coastal cities, large factories, or remote areas facing power shortages.
Right now, engineers are checking three main things to see if the project is feasible.
They are looking at the maritime and other laws that need to be followed, how to safely modify a nuclear reactor to sit and operate safely on a moving vessel and if the cost of the electricity generated justifies the price of building the ships.
The research teams will also take into account the specific marine architecture demands needed for the project to become a reality.
“Electric power demand is rapidly outstripping supply. Markets that need reliable electricity cannot wait for conventional infrastructure timelines,” concluded Bøe.
He also said that the U.S has the technology, the industrial base and the maritime heritage to lead the market.
According to the agreement, Core Power is financing the initial research and development by using its background and expertise in maritime logistics, nautical systems and vessel assembly.
