ENDL File Support – pyne.endl

Module for parsing and manipulating data from ENDL evaluations.

For the moment, classes and functions in this module only implement the specifications relevant to the EEDL (Evaluated Electron Data Library) and the EPDL (Evaluated Photon Data Library). The formats are described by the following documents:

“ENDL type formats for the Livermore Evaluated Photon Data Library, EPDL” https://www.oecd-nea.org/dbdata/data/manual-endf/nds_eval_epdl.pdf

“ENDL type formats for the Livermore Evaluated Electron Data Library, EEDL” https://www.oecd-nea.org/dbdata/data/manual-endf/nds_eval_eedl.pdf

For more information, contact Davide Mancusi <davide.mancusi@cea.fr>.

class pyne.endl.DataTuple

Create new instance of DataTuple(yo, limits, x1)

limits

Alias for field number 1

x1

Alias for field number 2

yo

Alias for field number 0

class pyne.endl.Library(fh)[source]

A class for a file which contains multiple ENDL tables.

get_rx(nuc, p_in, rdesc, rprop, x1=None, p_out=None)[source]

Grab the data for one reaction type.

Parameters:

nuc : int

id form of nucleus to read from.

p_in : int

ENDL incident particle designator

rdesc : int

ENDL reaction descriptor

rprop : int

ENDL reaction property

x1 : int or None

ENDL atomic subshell indicator (if applicable)

yo : int or None

ENDL outgoing particle designator (if applicable)

Returns:

data : NumPy array

Contains the reaction data in a n-by-m-dimensional array. The values of n and m depend on the reaction property rprop.
