ZZ-POINT-2009

This most recent library is identified as ENDF/B-VII.0; this is the first release of ENDF/B-VII. This release completely supersedes all preceding releases of ENDF/B.

As distributed the ENDF/B-VII.0 data includes cross sections represented in the form of a combination of resonance parameters and/or tabulated energy dependent cross sections, nominally at 0 Kelvin temperature.

For use in our applications the ENDF/B-VII.0 library has been processed into cross sections at eight neutron reactor like temperatures, between 0 and 2100 Kelvin, in steps of 300 Kelvin (the exception being 293.6 Kelvin, for exact room temperature at 20 Celsius). It has also been processed to five astrophysics like temperatures, 1, 10, 100 eV, 1 and 10 keV. For reference purposes, 300 Kelvin is approximately 1/40 eV, so that 1 eV is approximately 12,000 Kelvin. At each temperature the cross sections are tabulated and linearly interpolable in energy.

This library contains all of the evaluations in the ENDF/B-VI.0 general purpose library. A table in the appendix summarizes the contents of the ENDF/B-VII.0 general purpose library. This library contains evaluations for 393 materials (isotopes or naturally occurring elemental mixtures of isotopes).

This library does not contain data from special purpose ENDF/B-VII libraries, such as fission products, thermal scattering, photon interaction data. To obtain any of these special purpose libraries contact the National Nuclear Data Center, Brookhaven National Laboratory,

All results are in the computer independent ENDF-6 character format

The PREPRO 2009 code system was used to process the ENDF/B data. Listed below are the steps, including the PREPRO2009 codes, which were used to process the data in the order in which the codes were run.

1. Linearly interpolable, tabulated cross sections (LINEAR)

2. Including the resonance contribution (RECENT)

3. Doppler broaden all cross sections to temperature (SIGMA1)

4. Check data, define redundant cross sections by summation (FIXUP)

5. Update evaluation dictionary in MF/MT=1/451 (DICTIN)
   For the "cold" (0 Kelvin) data steps 1), 2) and 4), 5) were used (no Doppler broadening). For the data at other temperatures, after steps 1) and 2), the data was Doppler broadened to each temperature using step 3), and the results were then made consistent with the ENDF/B formats and conventions using steps 4) and 5), to produce the final distributed data.

The result is linearly interpolable in energy, tabulated, temperature dependent cross sections, in the ENDF-6 format, ready to be used in applications.

Due to recent changes in ENDF-6 Formats and Procedures only the latest version of the ENDF/B Pre-processing codes, namely PREPRO 2009, can be used to accurately process all current ENDF/B-VII evaluations. The use of any earlier versions of these codes may occasion inaccurate results.
