The fault tree ... is primarily a tool for proper and formally correct definition of problems to be analysed. Use of the fault tree for numerical evaluation of failures rates and probabilities is considered secondary. ... A fault tree is a hierarchically structured graphical representation of system failures and their potential causes. The system failures include in this context all the relevant malfunctions and other concerns which interfere with the proper functioning of a system. 2, record 2, English, - fault%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 3, 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 3, French, - technique%20dite%20%C2%ABarbre%20d%26rsquo%3B%C3%A9v%C3%A9nements%20et%20arbre%20de%20d%C3%A9faillances%C2%BB

The need to gain a better understanding of the risks associated with the operation of increasingly complex nuclear facilities can be satisfied in large measure by the use of the fault tree technique. This technique provides a powerful tool for the presentation, in a precise and logical manner, of the possible ways in which a system can fail. It also permits thorough examination of the design of a facility to identify links between systems whose malfunction could result in a release of radioactive material to the environment, and those systems which are designed to prevent or mitigate the effects of such failures. 2, record 4, English, - fault%20tree%20technique

La technique de l'arbre de défaillances est une méthode qui permet de mieux comprendre, dans une large mesure, les risques qui accompagnent l'exploitation des installations nucléaires sans cesse plus complexes. Grâce à cette technique, on peut présenter de façon précise et logique les diverses possibilités de défaillances d'un système. Cet arbre permet également d'examiner la conception d'une installation afin d'identifier les relations entre les systèmes dont la défaillance peut entraîner le rejet des matières radioactives dans l'environnement et les systèmes qui sont conçus pour prévenir ou atténuer les effets de telles défaillances. 2, record 4, French, - technique%20de%20l%27arbre%20de%20d%C3%A9faillances
