An event tree graphically represents the various accident scenarios that can occur as a result of an initiating event (i.e., a challenge to plant operation). Toward that end, an event tree starts with an initiating event and develops scenarios, or sequences, based on whether a plant system succeeds or fails in performing its function. 2, record 2, English, - event%20tree

One method used to uncover all the things that could go wrong is the "event tree/fault tree" analysis technique. Event tree work is not unlike following a multi-branched trail of dominoes as they knock each other over in sequence. Such analysis allows the tracing of things that could occur after the initiating events. Paths of action and consequences are traced, sometimes to great length. The fault tree technique, a favorite tool of AECB staff members, is a means of finding out what combinations of component and system failures would cause an event in the first place. It provides a systematic method of checking that the systems being relied on to prevent something worse happening won't be knocked out by the event itself. 1, record 4, English, - event%20tree%2Ffault%20tree%20analysis%20technique

Pour déterminer quels éléments pourraient être défectueux, on utilise notamment la technique dite «arbre d'événements et arbre de défaillances». Utiliser cette méthode, c'est un peu comme suivre des dominos alignés suivant un parcours à plusieurs embranchements. On établit ainsi les événements qui pourraient se produire après l'événement initial et on trace des plans d'action linéaires (parfois très longs) et leurs répercussions en cascade. L'arbre de défaillance est l'instrument préféré des spécialistes de la CCEA, car il leur permet de déterminer les combinaisons de défaillances des composants et des systèmes qui pourraient être à l'origine d'un événement. C'est là une façon rigoureuse de s'assurer que le système mis en place pour empêcher des conséquences plus graves ne sera pas neutralisé par l'événement lui-même. 1, record 4, French, - technique%20dite%20%C2%ABarbre%20d%26rsquo%3B%C3%A9v%C3%A9nements%20et%20arbre%20de%20d%C3%A9faillances%C2%BB
