IEC 63413 ED1

Nuclear Power Plants - Instrumentation and control systems important to safety - Platform qualification

Scope

IEC 63413:2025 provides guidance and establishes requirements for the qualification of I&C platforms, according to IEC nuclear standards, aimed to be used in nuclear applications important to safety. Qualification of an I&C platform (also called pre-qualification or generic qualification) is performed as a generic activity outside the framework of a plant-specific application project. Platform qualification aims to fulfil in an anticipated manner all requirements leading to an I&C platform fully suitable for the implementation of a plant-specific application project.
The platform qualification covers consequently all I&C platform specific aspects including hardware, software, HPD, engineering tools, environmental qualification, quality and the applied safety life cycle supporting these activities. Platform qualification also considers interaction of platform assemblies. This document applies to I&C platforms under development, as well as to pre-existing I&C platforms.
This document provides guidance on what is relevant to I&C platform qualification and what is relevant to the implementation of an I&C system design based on a qualified I&C platform.
The objective of this document is to identify those requirements that relate closely to an I&C platform qualification and aims to support a two-step approach for the licensing of I&C systems based on this I&C platform. If the complete qualification of an I&C system is performed in the framework of a plant-specific application, this document does not apply.
