SC 45A - Instrumentation, control and electrical power systems of nuclear facilities
To prepare standards applicable to the electronic and electrical functions and associated systems and equipment used in nuclear energy generation facilities (nuclear power plants, fuel handling and processing plants, interim and final repositories for spent fuel and nuclear waste) to improve the efficiency, safety and security of nuclear energy generation. Our standards cover the entire lifecycle of these instrumentation, control and electrical power systems, from conception, through design, manufacture, test, installation, commissioning, operation, maintenance, aging management, modernization and decommissioning. Our core domain is instrumentation, control and electrical power systems important to safety in nuclear energy generation facilities. The nuclear sector has its own well-developed safety philosophy and methodology, hence our safety publications address the differences from the generic approach and provide directives specific to nuclear energy related facilities with an all-encompassing approach to safety. According to the TC 45/IAEA agreement our nuclear sector safety and security standards implement principles and terminology of the IAEA safety and security guides. The core domain includes the radiation monitoring instrumentation used for monitoring, control and safety actuation functions. Our domain includes instrumentation, control and electrical power systems used in nuclear energy generation facilities to manage and control nuclear materials in the frame of international agreements and to safeguard nuclear material and prevent its illicit trafficking. Joint work and/or liaison will be undertaken in case of overlapping functions with radiological and environmental monitoring. An aspect of our charter is the application of emerging electronic techniques in order to meet nuclear instrumentation and control requirements, particularly computer systems and advances in information processing and control, including artificial intelligence. In this context, one of our strategic tasks is to review and comment on drafts of IAEA safety and security codes in order to maintain consistency between IAEA and IEC documents and identify detailed technical aspects for which IEC standard developments are appropriate and responsive to the market needs.
Systèmes d’instrumentation, de contrôle-commande et d'alimentation électrique des installations nucléaires
Préparer des normes applicables aux fonctions électroniques et électriques et aux systèmes associés et aux équipements utilisés dans les installations de production d'énergie nucléaire (centrales nucléaires de puissance, usines de transformation et de manutention du combustible, traitements des dépôts intermédiaires et finaux pour le combustible usé et des déchets nucléaires) afin d'améliorer l'efficacité et la sécurité de la production d'énergie nucléaire. Nos normes couvrent l'ensemble du cycle de vie de ces systèmes d'instrumentation, de contrôle, et électriques, de la définition, grâce à la conception, la fabrication, les tests, l'installation, la mise en service, l'exploitation, l'entretien, la gestion du vieillissement, la modernisation et la mise hors service. Notre cœur de métier est celui des systèmes d'instrumentation et de contrôle, importants pour la sûreté dans les installations de production d'énergie nucléaire. Le secteur nucléaire a sa propre philosophie de développement de la sécurité et de la méthodologie, d'où nos publications de sécurité portant sur les différences de l'approche générique, et donnant des directives spécifiques relatives aux installations d'énergie nucléaire avec une approche globale de la sécurité. Selon l'accord TC 45/AIEA, nos normes de sécurité du secteur nucléaire mettent en œuvre les principes et la terminologie des guides de sûreté de l'AIEA. Le domaine central comprend l'instrumentation de contrôle du rayonnement pour des fonctions de sécurité de surveillance, de commande et d'actionnement. Notre domaine comprend l'instrumentation, le contrôle et les systèmes électriques utilisés dans les installations de production d'énergie nucléaire pour gérer et contrôler les matières nucléaires dans le cadre des accords internationaux et de sauvegarder ses matières nucléaires et d'empêcher leur trafic illicite. Des travaux joints et/ou de liaison seront entrepris en cas de chevauchement des fonctions avec la surveillance radiologique et environnementale. Un aspect de notre charte est l'application des techniques électroniques émergentes afin de répondre aux exigences d'instrumentation et de contrôle nucléaires, en particulier les systèmes informatiques et les progrès dans le traitement et le contrôle des informations, y compris l'intelligence artificielle. Dans ce contexte, l'une de nos tâches stratégiques consiste à examiner et commenter les projets de code de sécurité de l'AIEA afin de maintenir la cohérence entre les documents de l'AIEA et de la CEI et d'identifier les aspects techniques détaillés pour lesquels des développements de normes IEC sont appropriés et répondent aux besoins du marché.

The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
