The vulnerability of industrial equipment to tsunami
No full textThe evaluation of vulnerability of process equipment to natural events is a central issue in the analysis of NaTech risks (Natural events triggering Technological accidents). Among others, the recent event in Japan has alerted the public opinion regarding the occurrence of tsunamis, which may result in dramatic consequences, either related to economic losses due to service interruption and repair costs, or for escalation of the tsunami towards severe catastrophic scenarios related to the loss of containment for the damaged equipment. Hence, environmental pollution, toxic dispersions, fires or explosions, depending on the stored, processed or transported fluid, on the structural design, and on the type of process operations.
In this work, the hazard related to tsunami impact on industrial equipment has been analyzed, either for the natural event characterization (intensity measure, hazard), or for the particular critical infrastructure. Vulnerability (or Fragility) functions have been specifically defined with respect to tsunami wave and debris

Comparison of the explosion thermodynamics of TNT and black powder using le chatelier diagrams
Full text linkLe Chatelier diagrams may be adopted for the definition of thermodynamic loci of explosion in terms of internal energy with respect to the temperature for either the primary explosion or for the deflagrative, post-combustion of the products of the first reaction with air, the afterburning reaction. In this paper, Le Chatelier diagrams are produced for TNT and black powder by using the CEA code. Pressure plots with respect to density or air/fuel ratio are also shown. These results are useful for the simulation of explosion (hydrodynamic codes), and more generally for the definition of safety of storage, transportation, and production of explosives and pyrotechnics. Furthermore, the method can be easily extended to any deflagrative pyrotechnic substances, for which information on explosion and afterburning effects are needed.
