Multi-compartment model dispersion and transmutation.
MULTILLABY is a multi-compartment model for nuclide dispersion with the following physical phenomenon:
|in a compartment volume
|from one compartment to another compartment
|on a compartment walls or inside a filter
|from one compartment to another
|from walls of a compartment or from a filter into another compartment
|between isotopes individualized with one or several chemical form
Isotopes are individualized with one or several chemical form (example Iodine: I2, ICH3 or I aerosol). Parameters of each physical phenomenon can be set for each chemical form.
|Code and nuclear data are small (only 200 Ko).
|Quantities and integral of quantities are computed directly from generalized H. Bateman equations.
|A simple input instruction text file is needed.
|The choice of the algorithm enables maximal speed and precision but loops are not possible (example: recirculation of air in a loop from a compartment back to a previous compartment is not computed).
