Growing environmental concerns are reigniting interest in nuclear propulsion as a potential long-term solution for decarbonizing shipping, according to DNV’s recent report. Despite a hiatus of over four decades without civilian nuclear-powered vessels, the paper, titled Maritime Nuclear Propulsion: Technologies, Commercial Viability, and Regulatory Challenges for Nuclear-Powered Vessels, explores the unique aspects of maritime nuclear technologies compared to land-based reactors. It emphasizes the need to tackle technological, regulatory, and commercial challenges to assess nuclear propulsion’s future role.
The report outlines key elements of the maritime fuel cycle, including fuel management, waste handling, and vessel operation, while identifying reactor technologies likely to be adopted by shipowners. Advances in automation and modular design are noted as crucial for enhancing safety and public acceptance of nuclear solutions. A harmonized regulatory framework at both national and international levels is essential for ensuring safe nuclear operations at sea, with regulators like the IMO and IAEA needing coordinated efforts.
For nuclear propulsion to be commercially viable, the business case must consider lifecycle costs, including fuel supply and waste management. The report suggests that modular designs can lower costs and enhance investor confidence, highlighting the importance of a strategic approach to the industry’s future.
