In order to protect the safety functions of nuclear power plants, it has appeared necessary to assess the risks which may result from their industrial environment such as those entailed by the transport or the storage of dangerous materials in the vicinity of power plant sites. Thus, a particular attention must be paid to consequences of release of materials that may form dense gas mixtures with air such as Liquified Natural Gas, Propylene, Chlorine...
