ISO 18136-1:2025 PDF

This document describes a shared conceptual framework for the nuclear digital ecosystem (NDE). In addition, this framework also serves as a systematic basis for a series of additional standards for management methods and technical guidelines for information integration and exchange, specifically in the nuclear industry. The framework focuses on the nuclear industry-specifics with management requirements as well as information specifications to facilitate practical benefits from implementing ISO standards. It is viable because the industry scope is narrowed down to the nuclear sector, while the management concerns are expanded to cover the various disciplines throughout the entire life cycle. The following are within the scope of this document: — definition of the conceptual structure of the nuclear ecosystem with components and relationships in terms of facility type, life cycle (lifetime), and technical management methodology; the scope of this document exclusively addresses ‘all reactor-related facilities’; — definition of the industry sectors involved within NDE, encompassing civil, architectural, mechanical, electrical, I&C, process engineering and ICT; — list of high-level constituents for each component; — instructions to guide the collective use of this document and existing standards to specify information requirements within the NDE for different functional purposes. The following are outside the scope of this document: — definition of detailed management methodologies or processes related to the standard data exchange; — list of detailed properties and structures of the required information exchange (IE).
