armi.nuclearDataIO.cccc.pmatrx module

Module for reading PMATRX files which contain gamma productions from fission reactions.

armi.nuclearDataIO.cccc.pmatrx.compare(lib1, lib2)

Compare two XSLibraries, and return True if equal, or False if not.

armi.nuclearDataIO.cccc.pmatrx.compareNuclideXS(nuc1, nuc2)

armi.nuclearDataIO.cccc.pmatrx.addDummyNuclidesToLibrary(lib, dummyNuclides)

This method adds DUMMY nuclides to the current PMATRX library.

Parameters:

• lib (obj) – PMATRX library object

• dummyNuclides (list) – List of DUMMY nuclide objects that will be copied and added to the PMATRX file

Notes

Since MC2-3 does not write DUMMY nuclide information for PMATRX files, this is necessary to provide a consistent set of nuclide-level data across all the nuclides in a XSLibrary.

armi.nuclearDataIO.cccc.pmatrx.readBinary(fileName)

Read a binary PMATRX file into an IsotxsLibrary object.

armi.nuclearDataIO.cccc.pmatrx.readAscii(fileName)

Read an ASCII PMATRX file into an IsotxsLibrary object.

armi.nuclearDataIO.cccc.pmatrx.writeBinary(lib, fileName)

Write the PMATRX data from an IsotxsLibrary object to a binary file.

armi.nuclearDataIO.cccc.pmatrx.writeAscii(lib, fileName)

Write the PMATRX data from an IsotxsLibrary object to an ASCII file.

class armi.nuclearDataIO.cccc.pmatrx.PmatrxIO(fileName, xsLib, fileMode, getNuclideFunc)

Bases: Stream

readWrite()

Read and write PMATRX files.

Implementation: Tool to read and write PMATRX files. I_ARMI_NUCDATA_PMATRX

signature: readWrite requirements: R_ARMI_NUCDATA_PMATRX

Reading and writing PMATRX files is performed using the general nuclear data I/O functionalities described in I_ARMI_NUCDATA. Reading/writing a PMATRX file is performed through the following steps: Read/write global information including: Number of gamma energy groups Number of neutron energy groups Maximum scattering order Maximum number of compositions Maximum number of materials Maximum number of regions Read/write energy group structure for neutrons and gammas Read/write dose conversion factors Read/write gamma production matrices for each nuclide, as well as other reaction constants related to neutron-gamma production.
