Navigating Nuclear Energy in Maritime with Lloyd’s Register at Helm

Lloyd’s Register (LR) has published a new guidance document, providing the first roadmap for the safe and responsible use of nuclear technology in commercial shipping and offshore industries.

As the maritime sector accelerates its transition towards sustainable energy solutions, nuclear power has re-emerged as a viable solution to achieve net-zero ambitions.

The guidance, Navigating Nuclear Energy in Maritime, was developed in partnership with Global Nuclear Security Partners (GNSP) and marine insurer NorthStandard.

It sets out the practical steps project teams must take, outlining regulatory, technical, operational and financial requirements for integrating nuclear technology, such as small modular reactors (SMRs), into maritime assets.

With no international regulatory framework yet in place, the document discusses the roles of key bodies, including the International Maritime Organization (IMO) and the International Atomic Energy Agency (IAEA), highlighting the importance of harmonising maritime and nuclear standards.

Topics covered include safety classification, environmental impact assessments, structural integrity, and the development of a robust nuclear safety case. Security measures are also addressed, with emphasis on physical and cyber protection systems, as well as insider threat mitigation.

Operational and financial aspects are thoroughly explored, including personnel qualifications, emergency response planning, and quality assurance throughout the
