ABS: Requirements for Marine Nuclear Power Systems

The American Bureau of Shipping has published requirements for Nuclear Power Systems for Marine and Offshore Applications, effective October 2024. This document outlines standards for the design, construction, and survey of vessels with nuclear power systems intended for non-propulsion purposes, including ships, barges, and offshore units.

The guidelines focus on ensuring the safe integration of nuclear power systems into marine and offshore applications. Early engagement with nuclear regulators and port authorities is crucial for clarifying responsibilities regarding design approvals. The requirements reference the International Convention for the Safety of Life at Sea (SOLAS) and the Code of Safety for Nuclear Merchant Ships, although the latter is considered outdated, with plans for updates aligning with new international standards as they emerge.

Stakeholder involvement, including contributions from flag administrations and nuclear regulators, is essential throughout the design and approval process. The document also includes a methodology for risk assessment, emphasizing safety functions and compliance. Additionally, it covers guidelines for hull design, reactor safety, control systems, radiological protection, fire safety, and monitoring systems.
