Description of output files

Reaction rate output

Calculation of analog reaction rates by counting the number of sampled interactions is invoked using the set arr option. The output is printed in file:

<input>_arr<bi>.m

where:

<input>	: is the name of the input file
<bi>	: is the burnup index (zero for first step or if no burnup calculation is run)

The data is printed in Matlab format in two variabls: string array "nuc", which contains the nuclide identifiers (ZA.id), and table "rr", consisting one row for each reaction and 7 columns:

1. Nuclide index corresponding to the entries in the nuc array
2. Reaction mt
3. Nuclide ZAI
4. Minimum energy of the reaction mode
5. Maximum energy of the reaction mode
6. Reaction rate
7. Relative statistical error of reaction rate

notes:

• The values are microscopic reaction rates integrated over all materials and energies.
• In photon transport mode
