The latest ENDF/B-VII.1 data library is now freely available through the National Nuclear Data Center (NNDC), Brookhaven National Laboratory. This release completely supersedes all preceding releases of ENDF/B. The ENDF/B-VII.1 data library was processed into the form of temperature dependent cross sections and is being distributed as POINT2012. Details on this and previous versions of this library can be found in the included documentation.

Compared to VII.0 which included 393 evaluations, VII.1 is comprised of 423 evaluations; this includes 32 new evaluations; 2 natural evaluations were dropped (23-V – Nat, and 30-Zn-Nat). See documentation for full list.


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


As distributed the original evaluated data includes cross sections represented in the form of a combination of resonance parameters and/or tabulated energy dependent cross sections, nominally at 0 K. For use in applications, this data has been processed using the 2012 version of the ENDF/B pre-processing codes PREPRO 2015 to produce temperature dependent, linearly interpolable in energy, tabulated cross sections, in the ENDF-6 format.


The steps required and codes used to produce room temperature, linearly interpolable tabulated cross sections, in the ENDF-6 format, are described below; the name of each code in given in parenthesis; for details of each code see reference.


Here are the steps, and PREPRO 2015 codes, used to process the data, in the order in which the codes were used.


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 K) 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.


Note - this processing only involved the energy dependent neutron cross sections. All other data in the evaluations, e.g., angular and energy distributions, was not affected by this processing, and is identical in all versions of the final results, i.e., it is the same in all of the directories, ORIGINAL, as well as 0K through 2100 K, and 1ev through 10 kev, on the DVDs.

No data retrieval program is included in the package. The PREPRO codes may be used to plot the POINT2015 data.  Mozilla Firefox can be used to access the data through the html index. Internet Explorer might require forward slashes in path names of the html index file to be changed to back slashes.

The ENDF Utility Codes for handling ENDF/B data may be used to access this data. The latest versions are available at NNDC


In this library each evaluation is stored as a separate file. The entire library is in the computer independent ENDF-6 character format, which allows the data to be easily transported between computers. The entire library requires approximately 15.1 gigabytes of storage. (D00273MNYCP00).
