Input
iternuc NZAI ZAI1 ZAI2 ... ZAINZAI [ NMAT MAT1 MAT2 ... MAXNMAT ]
| NZAI | : number of different nuclides (ZAI) included in the iteration |
| ZAIi | : the ZAI (e.g. 50100 for boron 10 ground state) of the nuclide to be included in the iteration |
| NMAT | : number of different materials included in the iteration (optional parameter) |
| MATi | : the name of the material to be included in the iteration |
Notes:
- If a list of materials is not given, all materials that contain the included nuclides are included in the iteration.
- The initial concentration of the nuclides to be iterated should be larger than zero.
- The critical concentration iteration currently only works for nuclides that have a reactivity effect mainly through neutron absorption. Specifically, critical concentrations of fissile, moderating or reflecting nuclides cannot be iterated using this card.
Output
An output variable ITER_NUC_FACTOR is included in the main [INPUT]_res.m results file.
