Fission Energy Release File Format
|
||||
==================================
|
||||
|
||||
This file is a compact HDF5 representation of the ENDF MT=1, MF=458 data (see
|
||||
ENDF-102_ for details). It gives the information needed to compute the energy
|
||||
carried away from fission reactions by each reaction product (e.g. fragment
|
||||
nuclei, neutrons) which depends on the incident neutron energy. OpenMC is
|
||||
distributed with one of these files under
|
||||
data/fission_Q_data_endfb71.h5. More files of this format can be created from
|
||||
ENDF files with the
|
||||
``openmc.data.write_compact_458_library`` function. They can be read with the
|
||||
``openmc.data.FissionEnergyRelease.from_compact_hdf5`` class method.
|
||||
|
||||
:Attributes: - **comment** (*char[]*) -- An optional text comment
|
||||
- **component order** (*char[][]*) -- An array of strings
|
||||
specifying the order each reaction product occurs in the data
|
||||
arrays. The components use the 2-3 letter abbreviations
|
||||
specified in ENDF-102 e.g. EFR for fission fragments and ENP for
|
||||
prompt neutrons.
|
||||
|
||||
**/<nuclide name>/**
|
||||
Nuclides are named by concatenating their atomic symbol and mass number. For
|
||||
example, 'U235' or 'Pu239'. Metastable nuclides are appended with an
|
||||
'_m' and their metastable number. For example, 'Am242_m1'
|
||||
|
||||
:Datasets:
|
||||
- **data** (*double[][][]*) -- The energy release coefficients. The
|
||||
first axis indexes the component type. The second axis specifies
|
||||
values or uncertainties. The third axis indexes the polynomial
|
||||
order. If the data uses the Sher-Beck format, then the last axis
|
||||
will have a length of one and ENDF-102 should be consulted for
|
||||
energy dependence. Otherwise, the data uses the Madland format
|
||||
which is a polynomial of incident energy.
|
||||
|
||||
For example, if 'EFR' is given first in the **component order**
|
||||
attribute and the data uses the Madland format, then the energy
|
||||
released in the form of fission fragments at an incident energy
|
||||
:math:`E` is given by
|
||||
|
||||
.. math::
|
||||
\text{data}[0, 0, 0] + \text{data}[0, 0, 1] \cdot E
|
||||
+ \text{data}[0, 0, 2] \cdot E^2 + \ldots
|
||||
|
||||
And its uncertainty is
|
||||
|
||||
.. math::
|
||||
\text{data}[0, 1, 0] + \text{data}[0, 1, 1] \cdot E
|
||||
+ \text{data}[0, 1, 2] \cdot E^2 + \ldots
