When the risk of an external event is evaluated using conventional PRA, a particular limitation is the difficulty in considering the timing at which nuclear power plant structures, systems, and components fail. To overcome this limitation, we coupled thermal-hydraulic and external-event simulations using Risk Assessment with Plant Interactive Dynamics (RAPID). Internal flooding was chosen as the representative external event, and a pressurized water reactor plant model was used. Equations based on Bernoulli’s theorem were applied to flooding propagation in the turbine building. In the analysis, uncertainties were taken into account, including the flow rate of the flood water source and the failure criteria for the mitigation systems. In terms of recovery action, isolation of the flood water source by the operator and drainage using a pump were modeled based on several assumptions. The results indicate that the isolation action became more effective when combined with drainage.","PeriodicalId":201963,"journal":{"name":"Proceedings of the 30th European Safety and Reliability Conference and 15th Probabilistic Safety Assessment and Management Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128702966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A central scope of interest is the design of mobile access systems, intended to replace the physical key. However, these systems do not only involve new use cases but also risks that place safety and security issues in the foreground of the system design. To ensure protection against safety and security risks, a procedure that allows multilevel system evaluation is necessary. Practical experience in risk assessment (SRA) shows field-specific approaches widely used. In order to facilitate an embedded safe and secure system design, this paper introduces a generic assessment method, which considers different system configurations and multilevel safety and security risks. Within this procedure, previously identified technical requirements are mapped in a Morphological Box (MB) to describe the configuration space (CS) of the system. In order to evaluate the system, use cases and sequences as well as misuse cases are mapped using UML. Identified threats and attack paths are transferred into fault and attack trees. The results of the fault tree analysis (FTA) and attack tree analysis (ATA) allows the definition of security requirements. Additionally, the process reveals non-standard scenarios that demand further detailed analysis. The proposed approach is applied to the example of an automotive mobile access system.","PeriodicalId":201963,"journal":{"name":"Proceedings of the 30th European Safety and Reliability Conference and 15th Probabilistic Safety Assessment and Management Conference","volume":"52 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114020908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
