armi.nuclearDataIO.cccc.pmatrx module

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

See [GAMSOR] and [MC23].

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._read(fileName, fileMode)

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.

armi.nuclearDataIO.cccc.pmatrx._write(lib, fileName, fileMode)

armi.nuclearDataIO.cccc.pmatrx._readWrite(lib, fileName, fileMode, getNuclideFunc)

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

Bases: armi.nuclearDataIO.cccc.cccc.Stream

Create an instance of a Stream.

Parameters

• fileName (str) – name of the file to be read

• fileMode (str) – the file mode, i.e. ‘w’ for writing ASCII, ‘r’ for reading ASCII, ‘wb’ for writing binary, and ‘rb’ for reading binary.
