Nuclear power plants - Instrumentation and control systems important to safety - Criteria for seismic trip system

IEC 63186:2021 specifies the minimum requirements for the design of the seismic trip system, and the components thereof, used in a nuclear power plant to mitigate seismic effects. This system is intended to shut down the reactor in operation automatically before it is significantly impacted by the vibratory ground motion incurred by strong earthquakes. This document is applicable to both the design of new built plants and the upgrading of plants in operation. It may be used for the design of other types of nuclear facilities where normal operation shall be stopped in case of strong seismic motions.

Centrales nucléaires de puissance - Systèmes d'instrumentation et de contrôle-commande importants pour la sûreté - Critères pour système de protection sismique

IEC 63186:2021 spécifie les exigences minimales pour la conception du système de protection sismique et de ses composants, utilisés dans une centrale nucléaire de puissance pour limiter les effets d'un séisme. Le système est prévu pour arrêter automatiquement le réacteur en fonctionnement avant qu'il ne soit endommagé de manière significative par le mouvement vibratoire du sol provoqué par de forts séismes. Le présent document est applicable à la conception de nouvelles centrales comme à la mise à niveau de centrales en exploitation. Il peut être utilisé pour la conception d'autres types d'installations nucléaires dont le fonctionnement normal doit être interrompu en cas de mouvements sismiques importants.

IEC TR 63415:2023(Main)
Nuclear Power plants - Instrumentation and control systems - Use of formal security models for I&C security architecture design and assessment

IEC TR 63415:2023 provides an overview over the formalized modelling and designing of cybersecure architectures to apply for I&C system cybersecurity enforcement at NPPs. The plant-specific risk assessment can use the techniques covered by this TR. This document considers the complex problem of NPP I&C architecture synthesis to address particular issues:
- asset classification,
- barrier measures assignment,
- the information transfer and links conformity with security requirements.
This document provides guidance on creating a comprehensive security model applicable to NPP I&C systems that describes NPP I&C cybersecurity architecture and aids in accomplishing the main tasks of I&C system secure design, which are:
- specification of system designs with increased determinism that enhance security,
- mapping of the security requirements into the security architecture of the I&C system,
- definition of the security requirements for information exchange between components within the I&C system, operators and other systems,
- assistance in the determination of the security degree assignment with a model-based technique considering asset properties and formal grouping of the assets,
design and establishment of security zones boundaries.
