LR releases nuclear maritime tech guidance

Developed in collaboration with Global Nuclear Security Partners and marine insurer NorthStandard, Navigating Nuclear Energy in Maritime details the regulatory, technical, operational and financial steps required to deploy nuclear solutions such as small modular reactors in maritime settings.

“Nuclear energy has the potential to transform maritime, providing a scalable and zero-carbon energy source that can accelerate the industry’s energy transition,” said Mark Tipping, LR’s Global Power to X director.

“However, its adoption requires clarity, collaboration and trust across regulators, operators, insurers and wider society.”

The document addresses the current lack of an international regulatory framework, highlighting the need for alignment between maritime and nuclear standards. It outlines the roles of key organisations such as the International Maritime Organisation and the International Atomic Energy Agency in shaping future governance.

Key areas covered include environmental impact assessments, safety classification, structural integrity and the development of a comprehensive nuclear safety case. Security is also a major focus, with recommendations on physical and cyber protection, as well as strategies to mitigate insider threats.

Operational and financial considerations such as crew qualifications, emergency planning, insurance challenges and liability frameworks are also explored to ensure project feasibility and long-term safety.

This guidance builds on LR’s earlier Fuel for Thought: Nuclear research.
