A recent study conducted by ULC-Energy, an Amsterdam-based nuclear consultancy, suggests that nuclear-powered bulk carriers could transform the shipping industry.
According to the results, these cargo ships could sail faster, longer and with lower operating costs, all while significantly reducing greenhouse gas emissions. greenhouse effect.
The study compared the efficiency of nuclear propulsion with traditional fuels, revealing that nuclear energy can be a sustainable alternative for large-scale dry cargo transportation.

Bulk carriers are crucial to global trade, transporting cargo such as grains, minerals and other dry goods.
With advances in civil nuclear technologies, the study explores the possibility of using them to power a Newcastlemax class bulk carrier – one of the largest categories of bulk carriers – replacing common low-sulfur fuel or green ammonia, considered a sustainable alternative.
Nuclear propulsion: space and efficiency
Among the main conclusions of the study, it is worth highlighting that the integration of a nuclear reactor in the Newcastlemax bulk carrier would not compromise the cargo capacity.
The addition of the reactor would take up minimal space, allowing the ship to maintain its transport capacity. In addition, nuclear power has proven to be the option with the lowest operating cost per ton transported, outperforming both green ammonia and conventional fuel (VLSFO).
Even with the higher initial cost of building a ship with a nuclear reactor, the fuel savings would pay off in the long run.
Dirk Rabelink, CEO of ULC-Energy, highlighted that the study reinforces the company’s mission to integrate nuclear technologies across different sectors. “This study advances our vision of providing unique insights into the use of nuclear technologies in new contexts.”, Rabelink said in a press release.
Environmental impact and regulatory challenges
One of the biggest attractions of nuclear propulsion is its contribution to sustainability. The study indicates that a nuclear-powered bulk carrier could operate with zero greenhouse gas emissions, representing an important step towards decarbonizing the shipping industry.
Compared to green ammonia-powered ships, which still produce some emissions, nuclear technology offers a clean and efficient alternative.
However, the study acknowledges that there are still significant challenges to implementing this technology.
In addition to operational complexities, there are regulatory and licensing issues that need to be overcome to make the adoption of nuclear reactors on commercial vessels viable.
Currently, many offshore reactor designs are in the conceptual stages, meaning cost estimates are preliminary and dependent on future advances in technology and regulation.
Niels De Vries, Head of Energy at C-Job, sees the study as an important milestone for the adoption of nuclear power in the maritime sector. “This study highlights how we can collaborate with customers and integrate systems in innovative ways to make shipping more sustainable.”, said De Vries.
He also praised the partnership with ULC-Energy and emphasized the importance of exploring sustainable alternatives that can change the dynamics of maritime transportation.
The future of shipping with nuclear-powered bulk carriers
Despite the challenges, C-Job and ULC-Energy are optimistic about the future of nuclear bulk carriers. Both companies believe that nuclear propulsion can make shipping more efficient and aligned with global sustainability goals.
The current research adds to a growing interest in using nuclear power to power ships, with some companies already exploring the feasibility of nuclear reactor-powered vessels for containers.
However, it is important to note that nuclear energy, even with all its potential for efficiency and sustainability, requires strict regulatory control.
International regulatory bodies will need to review and adapt their standards to incorporate this technology safely and efficiently.
The widespread adoption of nuclear energy in maritime transport will therefore depend on continued advances in research, as well as a favorable regulatory environment adapted to new needs.
The study by ULC-Energy and C-Job Naval Architects contributes to the debate on the transition to cleaner energy sources in the shipping sector, providing insights into how nuclear power can be integrated into large bulk carriers.
As industry seeks alternatives to reduce its carbon footprint, nuclear energy emerges as a promising option, but one that still requires joint efforts between industry and regulators to become a viable reality.
