Standards Development

Scope

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:

— major disciplines, including civil, architectural, mechanical, electrical, and instrumentation and control (I&C), process engineering, and information and communication technology (ICT);

— lifecycle (lifetime) of nuclear facilities, including planning, siting, design and engineering, procurement, construction, operation and maintenance (O&M), and decommissioning;

— global governance, including nuclear safety, nuclear security, and nuclear energy.

The followings are within the scope of this standard.

— definition of the conceptual structure of the nuclear ecosystem with components and relationships in terms of facility type, life cycle, and management methodology;

— definition of the industry sectors involved within NDE, encompassing civil, architectural, mechanical, electrical, I&C, process engineering and ICT;

— a list of high-level constituents for each component;

— instructions to guide the collective use of this standard and existing standards to specify information requirements within the nuclear digital ecosystem for different functional purposes.

The following are outside the scope of this standard.

— definition of detailed management methodologies or processes related to the standard data exchange;

— list of detailed properties and structures of the required information exchange.

NOTE 1 The scope of this document exclusively addresses ‘all reactor-related facilities’, but it also includes other nuclear facilities within its scope. The framework adheres to the four categories of nuclear facilities as designated by the International Atomic Energy Agency (IAEA) document entitled “Long Term Structure of the IAEA Safety Standards and Current Status”[46]. Four categories include nuclear power plants (NPPs), research reactors (RRs), fuel cycle facilities and facilities of the predisposal management of radioactive waste (FCFs), and waste disposal facilities (WDFs). Note that RR includes medical isotope reactors.

NOTE 2 Annex A illustrates the different representations of the NDE components. Annex B presents examples of coding systems used in nuclear projects incorporating NDE standard terms. Annex C presents relevant existing standards to help promote the actual implementation of the NDE standard. Annex D specifies a way to describe the context diagram of a system of interest to minimize interoperability issues. The relationship between ISO/TS 18101-1 and this document is defined in Annex E. Annex F describes configuration management and requirements management. Annex G discusses the feasibility of adopting this agreement to create a digital ecosystem. Finally, Annex H describes structured data and provides several examples of structured data.
