Abstract

This report is the deliverable of the task 2.3, a specification on the key features of efficient and integrated safety engineering process in the scope of the BESEP project. Safety engineering processes in the scope of BESEP support the safety design of the plant, special focus given to the assessment of the safety margin. The project focuses on finding the most efficient safety engineering practices to support safety margins determination and safety requirement verification for design basis exceeding external hazards. This task supports the overall aim of the project by describing the basis of the safety engineering.

The report suggests basic properties related to a structured safety engineering process in the scope of systems engineering (and the related standard ISO/IEC/IEEE 15288). A high-level safety engineering process is described through different system engineering workflow models, like the V-model, consisting of the system structure, the system life cycle stages and the systems engineering workflow phases.

The safety engineering process is also approached from a different angle by describing the safety margins concept and the failure analyses. Safety margins in the context of deterministic, probabilistic, and human reliability analyses are defined. Failure analyses are discussed in the context of the safety margin verification and in regards with the interaction between safety analyses, such as deterministic and probabilistic safety analyses and human factors engineering.

The report identifies the key aspects of an efficient and integrated safety engineering process, listing them to be used in later tasks of the project.
