sandy.sections.mf10 module

This module contains only two public functions:

• read_mf10

• write_mf10

Function read reads a MF10/MT section from a string and produces a content object with a dictionary-like structure. The content object can be accessed using most of the keywords specified in the ENDF6 manual for this specific MF section.

Function write_mf10 writes a content object for a MF10/MT section into a string. MAT, MF, MT and line numbers are also added (each line ends with a ` `).

sandy.sections.mf10.read_mf10(tape, mat, mt)

Parse MAT/MF=10/MT section from sandy.Endf6 object and return structured content in nested dictionary.

Parameters:

tapesandy.Endf6

endf6 object containing requested section.

matint

MAT number.

mtint

MT number.

Returns:

outdict

Content of the ENDF-6 tape structured as nested dict.

Examples

>>> import pprint
>>> tape = sandy.get_endf6_file("jeff_33", 'xs', 410930)
>>> test = read_mf10(tape, 4125, 16)
>>> test['AWR'] = round (test['AWR'],5)
>>> pprint.pprint(test, width=1)

sandy.sections.mf10.write_mf10(sec)

Given the content of a MF10 section as nested dictionaries, write it to string.

Parameters:

secdict

Content of the ENDF-6 tape structured as nested dict.

Returns:

str

Multiline string reproducing the content of a ENDF-6 section.

Notes

Note

The end-of-line records MAT, MF, MT and line number are added at the end of each line.

Important

The string does not end with a newline symbol.

Examples

String reproducing the content of a ENDF-6 section for (n,2n) of Nb-93 from the JEFF-33 library to obtain the cross sections for production of radiactive nuclides >>> tape = sandy.get_endf6_file(“jeff_33”, ‘xs’, 410930) >>> sec = read_mf10(tape, 4125, 16) >>> text = write_mf10(sec) >>> print(text)
