A method for interrelating safety related documents of a production plant

摘要

A method for interrelating safety related documents of a production plant, in particular a nuclear power plant, characterised in that said method comprises the following steps: identifying activity sources producing an output product which could cause a harmful impact on the environment as well as barriers surrounding said activity sources; establishing a fault tree following a cause/consequence activity release path along which the output product would reach said environment, said fault tree comprising said barriers and a set of logic gates and being established by progressive identification along said path of failure causes which could cause the considered barrier to release said output product, each logic gate comprises the logical operator defining the logical link between the failure causes associated with the considered barrier; and forming said documents by linking to each gate a description of said failure causes of the associated gate and at least one functional requirement field describing functions required for eliminating said failure cause. <IMAGE>
