IEC 62003:2020

Nuclear power plants - Instrumentation, control and electrical power systems - Requirements for electromagnetic compatibility testing

IEC 62003:2020 establishes requirements for electromagnetic compatibility testing of instrumentation, control, and electrical equipment supplied for use in systems important to safety at nuclear power plants and other nuclear facilities. The document lists the applicable IEC standards (principally the IEC 61000 series) which define the general test methods, and provides the necessary application-specific parameters and criteria to ensure that nuclear safety requirements are met.
This second edition cancels and replaces the first edition published in 2009. This edition includes the following significant technical changes with respect to the previous edition:
a) title modified.
b) expand the scope to encompass Electromagnetic Magnetic Compatibility (EMC) considerations for electrical equipment.
c) provide guidance for addressing the use of wireless technology.
d) enhance the description of the electromagnetic environment to provide clarification when selecting custom test levels or for test exemptions.
e) include example information to be contained within an EMC test plan.
f) provide guidance for characterization of the electromagnetic environment at the point of installation within a nuclear facility.

Centrales nucléaires de puissance - Systèmes d'instrumentation, de contrôle-commande et d'alimentation électrique - Exigences relatives aux essais de compatibilité électromagnétique

l'IEC 62003:2020 établit des exigences pour les essais de compatibilité électromagnétique du matériel d'instrumentation, de contrôle-commande (I&C) et d’alimentation électrique utilisé dans les systèmes importants pour la sûreté des centrales nucléaires et dans d'autres installations nucléaires. Le présent document donne la liste des normes IEC applicables (essentiellement la série IEC 61000) qui définissent les méthodes d'essai générales et fournit les paramètres et critères propres à l'application qui sont nécessaires pour garantir le respect des exigences de sûreté nucléaire.
Cette deuxième édition annule et remplace la première édition parue en 2009.Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) modification du titre;
b) élargissement du domaine d'application afin d'y intégrer les remarques relatives à la compatibilité électromagnétique (CEM) du matériel électrique;
c) formulation de recommandations en ce qui concerne l'utilisation de la technologie sans fil;
d) amélioration de la description de l'environnement électromagnétique afin d'apporter des précisions lors du choix des niveaux d'essai personnalisés ou en ce qui concerne les dispenses d'essais;
e) intégration d'exemples d'informations à intégrer dans un plan d'essai CEM;
f) formulation de recommandations en ce qui concerne la caractérisation de l'environnement électromagnétique au point d'installation dans une installation nucléaire.
