NuProShip Pioneering Nuclear Propulsion In Shipping

Selected Reactor Technologies

The project evaluated 99 companies working on advanced reactor technologies and has shortlisted three promising types for detailed assessment:

1. Kairos Power (USA)
   • Technology: Fluoride High-Temperature Molten Salt Reactor (HTMR).
   • Features: Uses TRISO fuel particles, designed for efficient and robust operation under high temperatures.
2. Ultrasafe (USA)
   • Technology: Helium-cooled Gas Reactor.
   • Features: Also utilizes TRISO fuel particles, known for its resilience and high safety levels in extreme conditions.
3. Blykalla (Sweden)
   • Technology: Lead-cooled Reactor.
   • Features: Uses uranium oxide as fuel and offers high efficiency with advanced cooling mechanisms.

The TRISO fuel particles, celebrated for their durability and containment properties, play a key role in the Kairos Power and Ultrasafe reactors, making them highly resilient for nuclear propulsion systems.

Collaborative Partners

The NuProShip project is supported by a wide range of prominent partners:

• VARD: Responsible for integrating the reactor systems into various ship types and assessing technical challenges for future commercial use.
• DNV: Providing expertise in safety and risk management.
• Norwegian Maritime Administration: Supporting regulatory aspects.
• Knutsen Tankers: A shipowner involved in the project.
• IDOM: A Spanish nuclear consultancy.

Project Phases

• NuProShip I (Ending December 31, 2024): Focused on initial feasibility studies and reactor assessments.
• NuProShip II (2025-2027): A follow-up two-year project to refine nuclear propulsion solutions and evaluate the business viability of nuclear technology in shipping. This phase will also include insurance companies to assess risks and coverage options.

Funding & Innovation

NuProShip is funded by the Research Council of Norway, reinforcing the country’s commitment to sustainable and innovative solutions in maritime propulsion technology. The project’s goal is to make nuclear propulsion a viable option for reducing emissions and increasing efficiency in the shipping industry.
