sandy.aleph2.matrix_output module

This module contains all classes and functions necessary to work with the ALEPH-2 reaction rate matrix files produced as partial outputs in a burnup calculation.

sandy.aleph2.matrix_output.read_matrix_output(file)

Read ALEPH-2 reaction rate matrix output file. Entries are saved without an index and with the following colums:

• J: column index in the transition matrix

-“NUCLIDE_J: nuclide identifier of the daughter nuclide - DAUGHTER: ZAM of the daughter nuclide - I: row index in the transition matrix - NUCLIDE_I: nuclide identifier of the parent nuclide - PARENT: ZAM of the parent nuclide - CONC: concentration of the parent nuclide in $at/cm^3$ - RR: reaction rate in $1/s$ - JAC: jacobian in $at/cm^3/s$

Parameters:

filestr

ALEPH-2 reaction rate matrix output file.

Returns:

dfpandas.DataFrame

dataframe with reaction rates.
