Résumé / Abstract
The deliverable ROSA - Cause Consequence Analysis (CCA) of WP1 deals with the possible evolution of hazards into accidents. The initial points of the consequence analysis are the Starting Point Hazards (SPH) which are determined and described within the deliverable Hazard analysis and resulting Starting Point Hazard for ROSA 2. Based on this, the present deliverable examines the hazard evolutions with regard of possible measures and influences which suppress a further dangerous evolution of the identified Starting Point Hazards. This is modelled by event trees. This document contains three parts: Chapter 4 describes the generic structure and the generic components of the consequence analysis. Furthermore, the formal requirements and the formal construction of the ROSA event trees are introduced. In particular, the re-usability of parts of event tree is discussed. This requires a more detailed view of different types of event trees. The first part of the deliverable concludes with the example construction of the event tree for SPHs concerning overspeed. The second part including chapter 5 to chapter 13 presents the application of the ROSA Model for all Starting Point Hazards. The consequence analyses of SPHs are summarised if this is possible and helpful. The generic Barriers and the Neutralising Factors which mitigate the hazard evolutions are identified. The hazard evolutions result in different Accident Categories which are described within the deliverable Concept and Context of the ROSA Model 2 The Generic Barriers, the Neutralising Factors and the resulting Accident Categories are summarised in annex B Matrixes concerning SPHs, Barriers, Neutralising Factors and Accident Categories. Finally, this deliverable prepares the pursuing work on the Barrier Quantification Model (BQM)., RAPPORT DE CONTRAT
