Estimating the Probability of Fatalities in Long Tunnels with FDS and 1D Human Behavior

Oriol Rios – CERN

Abstract

Future Circular Collider (FCC) project. PBD approach was a sound approach to help design a safe infrastructure and proof the safety systems performance. FDS was necessary to solve the ventilation scenarios and corresponding flows. Some uncertainties and discrepancies behind FED calculations. If used consistently, it could be an indicator for probabilistic quantification of consequences. Quantitative risk analysis might be necessary to establish the cost-benefit solutions and check the results against acceptable risk profile limits.
