Releases: njoy/NJOY2016
NJOY2016.67
This update resolves a number of issues encountered when processing the newly released JENDL5 nuclear data library and TENDL-2021 library for evaluations with sub-actinide fission, and provides fixes for a few minor issues.
Due to an internal compiler error, gcc-11 will not be supported. Users should consider moving to gcc-12 or any version from gcc-7 to gcc-10.
The following minor changes and fixes are included in this version:
- several corrections to the ERRORR source code to remove compiler warning messages (these were made while looking into issue #211 for gcc-11 compilation)
- increased the nxcmax array size parameter in ACER to resolve issue #228
- increased the nthr array size parameter in PURR to resolve an issue in JENDL5 Mn55 (issue #233)
- fixed an issue for processing JENDL5 U235 in ACER (issue #237)
- correction in HEATR to properly retrieve the fission energy release component's Q value at 0 eV (issue #209 - there currently is no evaluation impacted by this change)
- corrected ACER following issue #188. Evaluations using LAW=7 in MF6 data that are added to the DLWH block are impacted by this change (i.e. for secondary particle types that are not the incident particle type). For ENDF/B-VIII.0, only the secondary alphas from MT16 in Be9 is impacted by the change.
- properly set the za in the case of sub-actinide fission (MF10 MT18 data) when using MF10 automated processing in GROUPR (issue #241)
- exclude fission from a>4 particle production matrices in GROUPR
- when using the ign option in GROUPR for predefined group structures, some of the newer options did not return the correct structure, this has been fixed
- an array size for reading in ENDF data was increased to accommodate a new evaluation
A large number of compiler warnings have now been resolved (unused variables, large static arrays converted into allocatable arrays, etc.). There are still a lot of warnings but their number is heavily reduced. For source files that were corrected in this way, the remaining warnings relate to equality comparisons for real values, unused dummy arguments in subroutines and potential 0 indices into arrays (in all cases, if statements prevented this from happening).
NJOY2016.66
This constitutes a major update of NJOY to accommodate the latest IAEA photonuclear data library (which uses non-isotropic photon distributions) and the mixed mode elastic scattering ENDF format (adopted in the ENDF format in November 2020).
The following is an overview of the major changes made to NJOY for this update:
- LAW=61 is now allowed for photonuclear ACE libraries (the secondary angular distributions are now tabulated in all cases instead of being assumed isotropic when using LAW=1 LANG=1)
- Some photonuclear libraries use MF6/MT18 but with a neutron multiplicity equal to 1 instead of nubar. A warning is now printed when this is encountered and the multiplicity is replaced with the appropriate nubar data.
- thermal scattering ACE files now support mixed mode elastic scattering (both coherent and incoherent elastic scattering are used), with appropriate updates to THERMR and MODER
- The XSS array and its size is now set in the common acecm module. Writing out the ACE file and locator checking for photonuclear and thermal scattering files has been enabled as well (previously only available for incident neutron and charged particle ACE files).
In addition, the following minor issues were fixed as well:
- fixed a typo in a reaction name printed by the ACER output (issue #195)
- fixed a crash in ERRORR using ENDF/B-VIII.0 U235 for MF34 covariance data (issues #122 and #203)
- increased the size of an array when processing photonuclear ACE files (issue #204)
- extended the CLAW (iwt=9,10) weight function to cover 1e-5 -- 2e7 eV
- fixed issues with ACELAW=33 for continuous energy neutron, charged particle and photonuclear files (issue #212)
- fixed an issue when using the special charged particle interpolation law (INT=6) in RECONR
- fixed an issue with MODER not being able to handle MF28 (atomic relaxation data) when converting ASCII to binary
Notes:
- While the second minor fix no longer results in a crash of NJOY, the resulting covariance matrix is not correct since only the first subsubsection is added to the output (NJOY still calculates the matrices for each subsubsection - see issue #205)
NJOY2016.65
NJOY2016.64
This fixes a bug in ACER when producing photonuclear ACE files using some TENDL2019 evaluations. The use of LAW=4 in MF6 of these evaluations lead to corrupted ACE files related to incorrect logic in counting secondary particle producing reactions.
This release addresses issue #201.
NJOY2016.63
This fixes a bug in ERRORR when using the 999 option. When using this option, the input and output tapes are not closed in Fortran. This causes problems in NJOY21 as the output from ERRORR isn't completely written to disk before the next module starts. This update simply closes files nitape and notape which resolves the issue.
In addition, some logic statements in the GROUPR conver and ACER convr subroutines have been corrected to fix failures in the test suite when building in Debug mode.
NJOY2016.62
This adds a number of changes to NJOY2016 contributed by Toshihiko Kawano, Bob McFarlane, IAEA and CIEMAT. In particular, the following changes were made:
- fixed an issue in PURR when nunx is not set to the default value (when nunx is set to anything else but 0 or the number of energy points in the unresolved energy region, purr will now properly calculate the probability tables for the given number of tables spread out over the entire unresolved resonance region)
- fixed an issue in RECONR where the wrong channel radius was used for the calculation of the phase shift
- array sizes were increased
- additional allocated arrays are now deallocated at the end of the subroutine in which they were created
- added consistency checking for probability tables in ACER for continuous energy libraries
NJOY2016.61
This release updates the physical constant to the CODATA2018 standard. The values are those recommended in the ENDF-6 Format manual as of this writing.
Because the physical constants were updated, many of the regression tests were changed. A careful check of the differences was made before release. Please see Pull Request #140 for more details.
Note: this replaces a previous tagged version 2016.61 that had issues when running the tests. Since no actual code is changed, the original tag was removed and replaced with this one.
NJOY2016.60
When processing new incident charged particle ENDF files, NaN values were discovered in the ACE files. This appeared to be due to an array index overflow. A parameter for the size was added so that we can more easily resize the array, and an error message was added to detect similar issues in the future.
NJOY2016.59
This release fixes a minor issue in ACER. Whenever an ACER check run changed the library suffix for thermal scattering libraries, it was ignored. Test 61 was added to the non regression tests.
This release addresses issue #163.
NJOY2016.58
This release fixes a processing issue for the IRDFF-II ENDF files in GROUPR.
This release addresses issue #124.
