Benchmark Exercise on Safety Engineering Practices: Results and Recommendations

This paper describes the results and recommendations of the Euratom research project Benchmark Exercise on Safety Engineering Practices (BESEP). The role of safety engineering as a bridging element between plant-level systems engineering and discipline-specific safety assessments is discussed and studied through the variety of the performed benchmark exercises. Recommendations and preliminary results are presented under the three main topics of the project, which are the efficient and integrated safety engineering process, the closer connection of deterministic and probabilistic safety analysis and human factors engineering, and the creation of a graded approach. In addition, an example diagram of the nine main steps of efficient and integrated safety engineering is presented to visualize interconnections between safety analyses, and how the analyses contribute to the overall safety assessment and the verification of safety requirements.
