Output interpretation

All FISPACT-II calculations possess at least two output files: an output file [fileroot].out and a runlog file [fileroot].log. The output contains a sequence of text outputs which are summarised in the following sections.

Header and run information

The output file always begins with a header identifying the release version of the code:

after which a run identification box is printed with a summary of the nuclear data, user input and simulation data. Note that only the initial nuclear data are identified here, although simulations with multiple nuclear data and/or spectra will have these summarised at the end of the output.

Printed after the header information is the box containing unique identifying information for the run, for example with a simulation of the Fusion Neutron Source (FNS) 5 minute irradiation of Inconel-600 at position #3 (part of the FISPACT-II fusion decay heat validation:

ATOMS output data

Each instance of the ATOMS keyword in the input file cause the output of a set of data in the output file:

1. Table keys (first ATOMS only)
2. The time line
3. Iron information (if IRON is used)
4. The inventory, including:
   • The heading line
   • A line for each nuclide above the MIND threshold
   • Nuclide table totals
   • Inventory summary
5. Inventory by element (if NOCOMP is not used)
6. Gamma spectra
7. Gamma-dose totals
8. Dominant nuclide lists (if NOSORT is not used)
9. Bremsstrahlung corrections (if BREMSSTRAHLUNG is used)
