In the first, second and third periods, the main results achieved are the following:
- The external hazards of interest in the benchmark exercise have been identified;
- Important safety requirement topics have been identified, analysed, and assigned for external hazards;
- Safety requirement topics have been elaborated to a set of more detailed safety requirements to create the benchmark baseline used in the cross-case and cross-group comparisons;
- Information on the risk-significance thresholds for the external hazards used in the PSA studies of BESEP countries has been collected and conclusions have been made;
- Project partner specific case studies have been specified and self-evaluations have been carried out for the case studies against the benchmark baseline;
- The partner specific case studies have been compared, e.g. for the interconnections and flow of information between different safety analyses, reflecting the integration of the applied safety engineering process;
- Generalised case studies have been created from the partner specific cases and the generalised case studies have been compared, e.g. for the amount of effort used and the risk significance of the involved external hazard and SSC, reflecting the efficiency of the applied safety engineering process;
- The experience from the benchmark exercise have been collected and summarized as recommendations under following topics:
- i) Best practices to conduct safety engineering,
- ii) Closer connection between safety analyses to verify adequacy of safety margins,
- iii) Graded approach to the deployment of more sophisticated safety analysis methods;
- Industrial Advisory Board (IAB) has been established for the project and two workshops and public dissemination events with IAB has been arranged;
- Collaboration platforms and dissemination channels have been created for the project;
- Several training events and BESEP summer school have been arranged;
- Project results have been disseminated in several meetings and conferences.
