Requirements for aerosol filters used in nuclear facilities against specified severe conditions — Part 1: General requirements
This document provides the general requirements associated with the specific characteristics of high efficiency particulate air (HEPA) filters used in nuclear facilities. This document provides the manufacturer with general requirements for the performance, design, construction, acceptance testing and quality assurance for HEPA filters used in nuclear facilities (for qualification and production tests). All types of HEPA filter used in such applications are covered, from the large size HEPA filters in exhaust HVAC systems to small size low flow rate cylindrical HEPA filters for glove boxes. The design, fabrication, inspection and testing, certificates with regards to their expected performances are mentioned. This document does not provide the specific conditions against which the nuclear filters are designed, tested and qualified. This document applies only to the filters used for nuclear heating ventilation air conditioning (HVAC) or control rooms habitability applications or applications related to the exposure to radioactive ionizing radiations (e.g. medical or radioactive aerosols applications) in the severe conditions (e.g. fire, high radioactive challenge). Filter housing qualification is not part of this document.
Exigences pour les filtres à aérosols utilisés dans les installations nucléaires dans des conditions sévères spécifiées — Partie 1: Exigences générales
Le présent document fournit les exigences générales associées aux caractéristiques spécifiques des filtres à air à très haute efficacité (HEPA) utilisés dans les installations nucléaires. Le présent document fournit au fabricant des exigences générales pour la performance, la conception, la construction, les essais d’acceptation, et l’assurance qualité des filtres HEPA utilisés dans les installations nucléaires (pour la qualification et les essais de production). Tous les types de filtres HEPA utilisés dans ce type d’applications sont couverts, des filtres HEPA de grande taille dans les systèmes d’extraction CVCA aux filtres HEPA cylindriques de petite taille à faible débit pour les boîtes à gants. La conception, la fabrication, l’inspection et les essais, les certificats relatifs à leurs performances attendues sont mentionnés. Le présent document ne fournit pas les conditions spécifiques dans lesquelles les filtres nucléaires sont conçus, soumis à essais et qualifiés. Le présent document ne s’applique qu’aux filtres utilisés pour le chauffage, la ventilation et le conditionnement d'air (CVCA) nucléaire ou les applications d’habitabilité des salles de contrôle ou les applications liées à l’exposition aux rayonnements ionisants radioactifs (par exemple, applications médicales ou pour aérosols radioactifs) dans des conditions sévères (par exemple, incendie, essai hautement radioactif, etc.). La qualification de l’enveloppe des filtres ne fait pas partie de ce document.
