MULTILLABY¶
Multi-compartment model dispersion and transmutation.
Purpose¶
MULTILLABY is a multi-compartment model for nuclide dispersion with the following physical phenomenon:
| mixing: | in a compartment volume |
|---|---|
| transfert: | from one compartment to another compartment |
| deposition: | on a compartment walls or inside a filter |
| filtration: | from one compartment to another |
| release: | from walls of a compartment or from a filter into another compartment |
| decay: | 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.
General Features¶
| Small: | Code and nuclear data are small (only 200 Ko). |
|---|---|
| Fast: | Quantities and integral of quantities are computed directly from generalized H. Bateman equations. |
| User friendly: | A simple input instruction text file is needed. |
| Limits: | 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). |
