Request for Information: Development of a Commercially Viable System-Centric Small Modular Reactor Concept for Deployment in the Marine Transportation System

The Hartford Steam Boiler Inspection & Insurance Company (HSB) is providing information on its inspection, engineering, and quality assurance services to support the development of maritime small modular reactors (SMRs). They argue that utilizing existing nuclear construction codes and a qualified workforce of boiler and pressure vessel inspectors will provide a clear safety basis and a ready infrastructure for the maritime nuclear industry.

The commenter provides a comprehensive technical and regulatory roadmap for the development of commercially viable SMR-powered vessels. They argue that success depends on a system-level approach involving standardization, clear liability frameworks, workforce development, and international regulatory harmonization rather than just reactor technology alone.
