An experiment of nuclear physics requires the design of a number of different systems, mutually interrelated and coexisting in the same limited physical space. A safety review requires a clear understanding of all the possible event chains leading to the most critical accident scenarios.
The event chains in many cases direct, in the sense that an event hitting a system damages it, with all the potential consequences of its failure.
The increasing complexity of the experiments nevertheless exposes to severe scenarios also in case that a system failure provoke a domino effect on other systems, components or structures located in the nearby.
This paper proposes a risk analysis method aimed to identify interactions between subsystems and to mitigate the hazard of domino effects.
