La sûreté d'une installation nucléaire à l'arrêt, en cours de déclassement ou en phase intermédiaire d'attente, de même qu'en fonctionnement, repose essentiellement sur l'existence de barrières entre la source de nuisance d'une part, l'homme et l'environnement de l'autre. Le terme de barrières désigne tous les éléments de construction qui assurent la protection contre l'irradiation par des écrans (mur, blindage) qui absorbent l'énergie des rayonnements, et le confinement de la contamination (enceinte étanche ou en dépression, dispositif de ventilation destiné à maintenir cette dépression, filtres pour arrêter les poussières contaminantes). 4, record 3, French, - enceinte%20de%20confinement

Le terme «confinement» désigne aussi la «précaution prise contre la dispersion de quantités inacceptables de matières radioactives au-delà d'une région contrôlée, même en cas d'accident de réacteur». Ce terme est aussi communément utilisé pour désigner le système de confinement lui-même. 7, record 3, French, - enceinte%20de%20confinement
