SCALE 6.1.1 Updates
CENTRM (Updated in SCALE 6.1.1, May 23, 2012)
CENTRM was updated to correct an issue that can lead to non-conservative keff values when using the 44-group ENDF/B-V data with CENTRM for high-leakage models with trace-element number densities below ~10‑9 atoms/barn-cm when running SCALE 5.1–SCALE 6.1. The effect on the 238-group ENDF/B-V, VI, and VII libraries is minimal. There is no effect on continuous-energy Monte Carlo calculations.
In the dozens of test cases examined thus far, the discrepancy appears only in cases that meet ALL of the following conditions.
- Calculations are performed with SCALE 5.1, 6.0 or 6.1.
- The number density of at least one nuclide has a small fractional concentration of 10-8 or less relative to the total mixture number density. Typically this corresponds to an absolute concentration less than ~10-9 to 10-10 atoms/barn-cm, but greater than zero.
- The SCALE 44-group ENDF/B-V library or a user-generated broad group library with few groups in the U-238 resolved resonance range (1 eV-4 KeV) is used.
- CENTRM is used for resonance self-shielding. This is the default behavior in SCALE 6.1, but NITAWL processing is the default behavior for SCALE 5.1 and 6.0 for the ENDF/B-V cross-section data, so the user must explicitly request CENTRM processing to observe the discrepancy with SCALE 5.1 or 6.0.
- The system is sensitive to the high-energy portion of the resolved range, which most commonly occurs for high-leakage systems. Low-leakage criticality and depletion models examined realized only a minimal impact.
Impact of CENTRM error on computed results:
- Continuous-energy KENO calculations do not use CENTRM and are not affected.
- The impact for all 238-group calculations examined thus far is small, on the order of a few pcm.
- Eigenvalues and isotopic concentrations computed for the 44-group ENDF/B-V depletion cases examined are not significantly affected, because these are low-leakage systems [reflected lattice geometries]. For most cases that meet all of the above criteria, including burned fuel criticality safety calculations that include small concentrations of fission products, the discrepancy introduces an error on the order of 100 pcm.
In a contrived case that artificially introduces a trace material into a plutonium nitrate system, a discrepancy of ~3% delta-k between the SCALE 6.1 and corrected SCALE 6.1.1 result has been observed. However, the SCALE development team has not observed an experimental benchmark or operational safety-related problem that exhibits an error on the order of this contrived numerical case.
After applying the patch, users should repeat any calculations where this discrepancy could affect results.
Lattice Physics Enhancements (Updated in SCALE 6.1.1, May 23, 2012)
Several minor updates for lattice physics calculations have been included for TRITON and NEWT. Users will realize improved performance where these specific features are utilized. The following issues have been resolved.
- Homogenization of kinetic parameters in NEWT: The delayed neutron fraction, beta, is currently homogenized by forward fission weighting. In this formulation, beta should be weighted by the nu-fission reaction rate. The current coding uses the fission reaction rate (i.e., without the nu). Users should expect differences in the homogenized values of kinetic parameters, which will impact subsequent transient analysis.
- TRITON TRACE Block: An issue was identified using the TRACE block in TRITON. The TRACE block now supports any nuclide in the ORIGEN light-element library. Previously in SCALE 6.1, only trace amounts of nuclides from the AMPX cross-section library could be added to depletion materials. The ORIGEN light-element library contains more nuclides than are available in the AMPX cross-section library.
- Depletion File ft71f001 Index Listing: TRITON provides an output edit for a table of contents of the data in the ORIGEN nuclide inventory file (i.e., ft71f001). This file can be used in follow-on ORIGEN-ARP and OPUS analyses. It was identified that the record numbers were not properly displayed for the two cumulative datasets (system-sum of materials and selected-sum of materials). This edit was corrected.
- KENO Depletion Message: TRITON increases the user-defined KENO parameters NSK and GEN for depletion analysis. A message was added to the TRITON output to notify users of the modified values.
- NEWT ARRAY block: Two issues were addressed for the NEWT ARRAY block. An error message was added in the case where an array is used in the model geometry without being defined in the ARRAY block. Second, a code bug was removed so that the model geometry may include multiple placements of the same array definition.
- CENTRM Cross-section processing defaults: TRITON supports several sets of CENTRM cross-section processing defaults: parm=2region, parm=centrm, and parm=(xslevel=1/2/3/or 4). An error was identified in depletion calculations if the user supplied parm=centrm. In this case, TRITON continued to use the depletion default set, which has been slightly modified to decrease run-time without significantly impacting depletion analysis. This error was resolved in this patch. For depletion calculations (i.e. =t-depl, =t-depl‑1d, =t5-depl, =t6-depl) that use parm=centrm, users can expect a small deviation (~50 pcm change in multiplication factor as a function of burnup) and slightly longer run-times for depletion models that utilize the parm=centrm option when using the SCALE 6.1.1 update.
MAVRIC/Monaco Enhancements (Updated in SCALE 6.1.1, May 23, 2012)
A few minor issues were identified with the SCALE fixed-source Monte Carlo code Monaco and an associated utility, especially related to seldom-used optional features. Users should review any results produced with these features using SCALE 6.1.
- When specifying the special distribution pwrNeutronAxialProfileReverse or pwrGammaAxialProfileReverse for a spatial source distribution, the un-reversed profile was erroneously returned.
- The sum of the point detector group-wise results may be higher than the point detector energy-integrated (total) results. The reported total is correct. The group-wise values are high due to rejecting negative contributions (which happen a small fraction of the time due to the multigroup energy/angle physics).
- If a source specification utilizes different Watt spectra distributions in multiple sources, the energies sampled for one source may include energies from the wrong distribution.
- The utility program mim2wwinp does not format MCNP *.wwinp files correctly for photon-only problems. MCNP interprets a *.wwinp with only one particle listed as neutrons, even in a "mode p" problem. The *.wwinp file produced by SCALE needs to specifically identify that there are 0 neutron groups for photon-only problems.
ORIGEN Data Enhancements (Updated in SCALE 6.1.1, May 23, 2012)
Three issues are corrected within the ORIGEN depletion and decay libraries.
- origen.rev03.jeff200g – The energy group boundaries of the 200-group JEFF-based ORIGEN library were inadvertently generated using constant lethargy boundaries instead of the boundaries of the SCALE 200-neutron and 47-gamma group cross section libraries. The library was regenerated to include the corrected boundaries. No other changes were made. All calculations performed with the previous version of the jeff200g library should be discarded and repeated with the current library.
- The fission product yield library used by COUPLE was modified to include ternary yields of H-3, He-3, and He-4 based on data from the JEF-2.2 fission yield library. In the previous library these fission products are only generated as by-products of neutron reactions other than fission, and not directly from fission. Cumulative yields are applied for H-3 and He-4, and direct yields are used for He-3 since it is a decay product of H-3. Direct yields for He-3 are zero for all fission nuclides.
- The ORIGEN decay libraries were updated to provide correct natural abundances of several elements. Previously, the use of natural isotopic abundances (NEX1=4) for input element concentrations entered in gram units may have resulted in incorrect isotopic concentrations for Mg, Ge, Kr, Sr, and Te. If atom units (gram atoms) were used, incorrect isotopic concentrations may have occurred for F, Na, Mg, Al, P, Sc, Mn, Co, Ge, As, Kr, Sr, Y, Nb, Rh, Te, I, Cs, Pr, Tb, Ho, Tm, and Au. The libraries origen.rev02.decay.data and origen.rev02.end7dec were updated.
KENO-VI Hexagonally-Pitched Arrays (Updated in SCALE 6.1.1, May 23, 2012)
KENO-VI was updated to correct an issue that occasionally caused a calculation to fail when tracking in a hexagonally-pitched array. Previous calculations that encountered this error failed, and the results of other calculations are not affected.
Other Enhancements (Updated in SCALE 6.1.1, May 23, 2012)
The SCALE 6.1 distribution included some sample problem output data that were generated with a prerelease version of SCALE and were not consistent with those produced by the final release of SCALE 6.1. Additionally, some of the sample problems were verified using output that included timing information, such as Figure of Merit data from Monte Carlo calculations. This update provides revised .out and .table files for all sample problems, updates in the XML files that drive the sample problems, corrections in platform-specific information in three Windows sample problem inputs, and provides an updated differencing tool that is used for comparing sample problem outputs.
Additionally, KENO3D and OrigenArp example files that are referenced in some publications but were not included in SCALE 6.1 are also installed with this update, and an updated version of GeeWiz is provided to correct minor issues.

SCALE 6.1.1 Known Issues
Minor Issues Identified with Fixed-Source Monte Carlo Capabilities
Corrected in SCALE 6.1.1
A few minor issues were identified with the SCALE fixed-source Monte Carlo code Monaco and an associated utility, especially related to seldom-used optional features. These features will be corrected in a pending patch for SCALE. These features should be used with caution until the patch is applied.
- When specifying the special distribution pwrNeutronAxialProfileReverse or pwrGammaAxialProfileReverse for a spatial source distribution, the un-reversed profile is erroneously returned.
Impact: This is a seldom-used feature that was implemented for compatibility with previous MORSE calculations. Problems run using one of the special axial distributions containing the word reverse are in fact not reversed, and erroneous results could result due to an inaccurate source specification.
- The sum of the point detector group-wise results may be higher than the point detector energy-integrated (total) results. The reported total is correct. The group-wise values are high due to rejecting negative contributions (which happen a small fraction of the time due to the multi-group energy/angle physics).
Impact: The energy-integrated results are correct. Only energy-dependent results are in error for some calculations. If the use of energy-dependent results is desired, users should verify that they sum to the total value.If a source specification utilizes different Watt spectra distributions in multiple sources, the energies sampled for one source may include energies from the wrong distribution.
- If a source specification utilizes different Watt spectra distributions in multiple sources, the energies sampled for one source may include energies from the wrong distribution.
Impact: Only models that implement more than one Watt spectrum are impacted. Since Watt spectra from different isotopes are quite similar, the impact of this discrepancy may not be noticeable. For Watt spectra that are very different, results may differ.
- The utility program mim2wwinp does not format MCNP *.wwinp files correctly for photon-only problems. MCNP interprets a *.wwinp with only one particle listed as neutrons, even in a "mode p" problem. The *.wwinp file produced by SCALE needs to specifically identify that there are 0 neutron groups for photon-only problems.
Impact: Subsequent MCNP calculations that use the SCALE generated .wwinp files for photon-only problems will not run.

Discrepancy Observed with Small Number Densities with 44-Group ENDF/B-V Data and CENTRM
Corrected in SCALE 6.1.1
An issue has been identified that can lead to non-conservative keff values when using the 44-group ENDF/B-V data with CENTRM for high-leakage models with trace-element number densities below ~10-9 atoms/barn-cm when running SCALE 5.1 – SCALE 6.1. The effect on the 238-group ENDF/B-V,VI, and VII libraries is minimal. There is no effect on continuous-energy Monte Carlo calculations.
In the dozens of test cases examined thus far, the discrepancy is only realized in cases that meet ALL of the following conditions:
- The number density of at least one nuclide has a small fractional concentration of 10-8 or less relative to the total mixture number density. Typically this corresponds to an absolute concentration less than ~10-9 to 10-10 atoms/barn-cm, but greater than zero.
- The SCALE 44-group ENDF/B-V library or a user-generated broad group library with few groups in the U-238 resolved resonance range (1 eV-4 KeV) is used.
- CENTRM is used for resonance self-shielding. This is the default behavior in SCALE 6.1, but NITAWL processing is the default behavior for SCALE 5.1 and 6.0 for the ENDF/B-V cross-section data, so the user must explicitly request CENTRM processing to observe the discrepancy with SCALE 5.1 or 6.0.
- The system is sensitive to the high-energy portion of the resolved range, which most commonly occurs for high leakage systems. Low-leakage criticality and depletion models examined realized only a minimal impact.
- Calculations are performed with SCALE 5.1, 6.0 or 6.1.
Impact on calculations:
- Continuous-energy KENO calculations do not use CENTRM and are not affected.
- The impact for all 238-group calculations examined thus far is small, on the order of a few pcm.
- Eigenvalues and isotopic concentrations computed for the 44-group ENDF/B-V depletion cases examined are not significantly affected, as these are low-leakage systems [reflected lattice geometries]. For most cases that meet all of the above criteria, including burned fuel criticality safety calculations that include small concentrations of fission products, the discrepancy introduces an error on the order of 100 pcm.
- In a contrived case that artificially introduces a trace material into a plutonium nitrate system, a discrepancy of ~3% delta-k was observed. This is the maximum discrepancy observed for the real and hypothetical systems examined thus far, but it should not be considered a bounding value.
Corrective Action
- The SCALE Team is developing a patch that corrects this issue.
- Users should examine calculations to determine if they meet the criteria provided above.
- The eigenvalue for suspect systems should be examined using a different library, such as the 238-group ENDF/B-V to determine if a particular system is impacted.
- Users should install the SCALE 6.1 patch when it is available and repeat any suspect calculations.

Optional Output Edit in STARBUCS
In STARBUCS burnup credit loading curve search calculations, an optional input prt=short may be used within the READ SEARCH input block to restrict the final output to contain only relevant information for a burnup loading curve calculation. In SCALE 6.1, this optional input causes the calculation to crash.
Users should only use the default parameter prt=long, which retains all SCALE output information for the last step of the iterative fuel enrichment search process. As prt=long is the default option in STARBUCS, there is no need for this input option to be specified in a STARBUCS input file.

MacOS System Requirements
The SCALE 6.1 Readme states that the system will operate on Mac OSX version 10.5 or newer, where Mac OSX 10.6 or newer is actually required to properly execute SCALE 6.1.
The symptoms are such that the SCALE runtime will execute and a job banner will be produced, but the executable modules will fail.
If messages are turned on (-m flag on the batch6.1 command) the following message will be reported:
'dyld: unknown required load command 0x80000022'
The solution is to upgrade to Mac OSX 10.6 or newer.

Windows ORIGEN and OPUS Sample Problems
Corrected in SCALE 6.1.1
There has been an issue identified when running the ORIGEN and OPUS sample problems on Windows.
Specifically, the sample problems' shell script uses an invalid path when attempting to copy needed resources into the working directory. Without these needed resources, both sample problems fail to produce the expected results.
The fix is simple. For the origen.input and opus.input files, located in
scale6.1\smplprbs\Windows, replace
=shell
copy z:\scale_staging\data\arplibs\w17_e40.arplib ft33f001
end
with
=shell
copy %DATA%\arplibs\w17_e40.arplib ft33f001
end

Unable to access jarfile ... ScaleDiff.jar
Corrected in SCALE 6.1.1
There has been an issue identified where when running the sample problems,
the ScaleDiff.jar file is not found producing an 'Unable to access jarfile ... ScaleDiff.jar' message.
The issue is due to not having the source code installed.
The ScaleDiff-Samples.xml zip file contains the following:
• samples.xml
• ScaleDiff.jar
Do the following to update your Scale6.1 install
1. Extract the contents into your Scale6.1 directory. You will be prompted to ‘copy and replace’ your samples.xml file.
2. Move the Scale6.1\ScaleDiff.jar file into your Scale6.1\cmds directory. You will be prompted ‘copy and replace’ your ScaleDiff.jar file.
The updated Scale6.1\samples.xml, and Scale6.1\cmds\ScaleDiff.jar files should be available to verify Scale as detailed in the readme file.
Updated: 11/15/2011
table_of_content_*.txt: no such file or directory
Corrected in SCALE 6.1.1
When running the sample problems an error may occur similar to the following,
C:\Scale6.1\Windows_amd64\bin\grep: table_of_content_*.txt: No such file or directory
This is due to a typo in the scale\samples.xml file.
'table_of_content_*' should be 'table_of_contents_*'. Notice the extra 's'.
Edit your Scale\samples.xml file, find 'table_of_content_*' and replace with 'table_of_contents_*'.

ORIGEN 200-group cross section library
Corrected in SCALE 6.1.1
A problem was identified in the energy-group boundaries of the ORIGEN 200-neutron-group cross-section library, origen.rev02.jeff200g. The boundaries were generated with constant lethargy instead of the boundaries of the SCALE 200-group transport library. Use of this library is currently not recommended, as it will produce erroneous results. An update to the library will be available soon.
Date Identified: 10/24/2011
ORIGEN natural isotopic abundances
Corrected in SCALE 6.1.1
The natural isotopic abundances for several elements in the ORIGEN library are incorrect. The abundances have been corrected and an updated library will be available soon. The use of natural isotopic abundances (NEX1=4) for input element concentrations enter in gram units may result in incorrect isotopic concentrations for Mg, Ge, Kr, Sr, and Te. If atom units (gram atoms) are used, incorrect isotopic concentration may occur for F, Na, Mg, Al, P, Sc, Mn, Co, Ge, As, Kr, Sr, Y, Nb, Rh, Te, I, Cs, Pr, Tb, Ho, Tm, and Au.

Problem with thermal energy cutoff in continuous-energy KENO calculations
Internal testing of continuous-energy calculations with KENO has revealed a considerable non-conservative change in keff, on the order of 20%, for cases involving BeO. Users who properly validate continuous-energy KENO calculations for these systems would notice a strong systematic bias for bound BeO cases prior to use in safety calculations. Nevertheless, users should not use be-beo in continuous-energy KENO calculations.
Note that multigroup calculations in KENO are not affected by this issue, and updates to the continuous-energy data for bound BeO will be available soon.
Further explanation:
Scale continuous energy neutron cross-section libraries are based on ENDF/B-VI Release 8 and ENDF/B-VII Release 0. While most of the neutron cross sections are for nuclides that are assumed to be free (not bound in a molecule), some nuclide cross sections are for bound nuclei that are commonly referred to as s(a,b) cross sections or thermal kernels. Hydrogen bound in water or Be in BeO are some example nuclei that have bound thermal cross sections. Scale continuous-energy neutron cross-section libraries were generated by processing the ENDF thermal kernel data for incident neutron energies of 5.05eV or below. To provide flexibility in analysis without the need to regenerate the cross section library, KENO was designed to implement a user-selectable value for the thermal cutoff for s(a,b) treatment, with default neutron cutoff energy of 3eV. Above this cutoff the effects of thermal motion of the molecule are assumed to be negligible.
As a result of a recent internal testing, it was discovered that KENO does not apply the thermal cutoff value to the use of s(a,b) treatment. If the evaluation does not have data up to 5.05eV, the short collision time method is used to extend the incoherent inelastic scattering data up to 5.05eV. Coherent elastic scattering is generated only for the energy range specified in the ENDF file. It was discovered that for Be in BeO, the coherent elastic and incoherent inelastic scattering cross sections extended beyond 3eV but did not have the same upper cut-off value. When KENO ignores the default thermal cut-off value of 3eV, it tries to sample from both coherent elastic and incoherent inelastic and obtains the wrong cross section between the cut-off values of these reactions.
