Chemical Incident Simulator

CHEMICAL INCIDENT SIMULATOR A NEW APPROACH FOR DERIVING PASSIVE DEFENCE REQUIREMENTS... [Pg.59]

The Chemical Incident Simulator simulates the dispersion of chemical warfare agents, detector responses, the effects of protective equipment, and die human toxicological responses for large numbers of scenarios. The possibilities and potentials offered by the Chemical Incident Simulator are illustrated best with an example. [Pg.66]

Thus, the Chemical Incident Simulation model largely eliminates the subjectivity involved in scenario studies, and procurement of protective and detector equipment. [Pg.69]

Information gained from simulations can reveal key insights that explain gaps or contradictions in information. The time line is a useful tool in this development. For incidents of unexpected chemical reactions, it is common to attempt a lab scale simulation of the conditions involved in the exotherm or explosion. Many chemical processes can be modeled and duplicated dynamically by computer algorithms. Accelerated rate calorimeters (ARC) have proven to he highly useful tools for studying exothermic or overpressure runaway reactions. [Pg.170]

The evaluation of chemical reaction hazards involves establishing exothermic activity and/or gas evolution that could give rise to incidents. However, such evaluation cannot be carried out in isolation or by some simple sequence of testing. The techniques employed and the results obtained need to simulate large-scale plant behavior. Adiabatic calorimeters can be used to measure the temperature time curve of selfheating and the induction time of thermal explosions. The pertinent experimental parameters, which allow the data to be determined under specified conditions, can be used to simulate plant situations. [Pg.925]

To interpret the results the code package TRIDYN + DIFFUSEDC + YCHEM was developed [33]. In TRIDYN H ions were added as additional incident species with fraction h = 75% in the beam. In addition to the inclusion of chemical sputtering by YCHEM (see Sect. 9.3) a concentration dependent diffusion of carbon was added using a diffusion coefficient D(C) as determined from separate experiments [33]. The chemical sputter yield Ychem was taken from literature data and was 10%. In Fig. 9.5 the results of the calculation are compared to experimental data for irradiation of W with CHg at 1000 K [34] and with pure C at 1030 K. The simulations reproduce the experimental values well within the error bars. One can clearly see, that the... [Pg.211]
