An as far as possible exhaustive conceptual approach has been developed to systematically address all kinds of internal and external hazards and their potential combinations in Level 1 PSA in a comprehensive manner. The approach assumes a comprehensive generic compilation of hazards being available. By means of site-specific screening process it is decided which hazards need to be analysed in detail by means of probabilistic methods. The requested extension of the plant model is carried out by a systematic approach for those hazards to be analysed in detail. For this purpose, lists of hazard relevant structures, systems and components and their failure dependencies according to the hazards are derived. The comprehensive extension of Level 1 PSA by hazards is demonstrated at the example of plant internal fires.
