Fusion installations — Criteria for the design and operation of confinement and ventilation systems of tritium fusion facilities and fusion fuel handling facilities

This document specifies the applicable requirements related to the design and the operation of confinement and ventilation systems for fusion facilities for tritium fuels and tritium fuel handling facilities specific for fusion applications for peaceful purposes using high tritium inventories, as well as for their specialized buildings such as hot cells, examination laboratories, emergency management centres, radioactive waste treatment and storage facilities. In most countries, a tritium quantity is declared as high for tritium inventories higher than a range of 10 g to 100 g. In the tritium fusion facilities in the scope of this document, the tritium inventory is deemed to be higher than this range for the whole site. This document applies especially to confinement and ventilation systems that ensure the safety function of nuclear facilities involved in nuclear fusion with the goal to protect the workers, the public and the environment from the dissemination of radioactive contamination originating from the operation of these installations, and in particular from airborne tritium contamination with adequate confinement systems. The types of confinement systems for other facilities are covered by ISO 26802 for fission nuclear reactors, by ISO 17873 for facilities other than fission nuclear reactors and by ISO 16647 for nuclear worksite and for nuclear installations under decommissioning. The facilities covered by these three standards, notably ISO 17873, include tritium as a radioactive material among the ones to be confined, but tritium is not their driver of the risks for workers and for members of the public. Nevertheless, the tritium quantities and risks from fusion facilities create specificities for a specific standard (e.g. in fusion facilities, tritium is the driver of routine and accident consequences). Therefore, the scope of this document does not cover the other facilities involved in tritium releases (ISO 17873, ISO 16647 and ISO 26802), even though these other facilities create tritium releases (e.g. non-reactor fission facilities, tritium laboratories, tritium removal facilities from fission plants, tritium defence facilities).

Installations de fusion — Critères pour la conception et l'exploitation des systèmes de confinement et de ventilation des installations de fusion avec tritium et des installations de traitement des combustibles de fusion

Le présent document spécifie les exigences applicables relatives à la conception et à l'exploitation des systèmes de confinement et de ventilation pour les installations de fusion des combustibles de tritium et pour les installations de traitement des combustibles de tritium utilisées spécifiquement pour les applications de fusion qui utilisent des inventaires de tritium élevés à des fins pacifiques, ainsi que pour les bâtiments spécialisés qui leur sont associés, tels que les enceintes blindées de haute activité, les laboratoires d'examen, les centres de gestion des situations d'urgence et les installations de traitement et d'entreposage des déchets radioactifs. Dans la plupart des pays, la quantité de tritium est réputée importante lorsque les inventaires de tritium dépassent la plage de 10 g à 100 g. Dans les installations de fusion avec tritium entrant dans le domaine d'application du présent document, l'inventaire de tritium est considéré comme étant supérieur à cette plage pour l'ensemble du site. Le présent document s'applique tout particulièrement aux systèmes de confinement et de ventilation qui assurent la fonction de sûreté des installations nucléaires impliquées dans la fusion nucléaire, dans le but de protéger le personnel, le public et l'environnement contre la dissémination des contaminations radioactives générées par l'exploitation de ces installations, et en particulier contre la contamination de tritium en suspension dans l'air, au moyen de systèmes de confinement adéquats. Les types de systèmes de confinement pour d'autres installations sont traités dans l'ISO 26802 pour les réacteurs nucléaires de fission, dans l'ISO 17873 pour les installations autres que les réacteurs nucléaires de fission et dans l'ISO 16647 pour les chantiers nucléaires et les installations nucléaires en démantèlement. Les installations traitées dans ces trois normes, notamment l'ISO 17873, incluent le tritium parmi les matières radioactives à confiner, mais celui-ci ne constitue pas leur facteur de risques principal pour le personnel et le public. Néanmoins, les quantités de tritium et les risques liés aux installations de fusion créent des spécificités qui appellent une norme spécifique (par exemple, dans les installations de fusion, le tritium est à l'origine des principales conséquences des situations de routine et d'accident). Par conséquent, le domaine d'application du présent document ne couvre pas les autres installations impliquées dans les rejets de tritium (ISO 17873, ISO 16647 et ISO 26802), même si celles-ci rejettent du tritium (par exemple, les installations de fission hors réacteur, les laboratoires de tritium, les installations d'élimination du tritium des centrales de fission, les installations de défense contre le tritium).
