1.   NAME AND TITLE OF DATA LIBRARY

POINT2009:      A Temperature-Dependent, Linearly Interpolable, Tabulated Cross Section Library Based on ENDF/B-VII.0.

 

2.   NAME AND TITLE OF DATA RETRIEVAL PROGRAMS

None included. Any codes which treat ENDF/B-VII format can be used as retrieval programs.

 

3.   CONTRIBUTOR

International Atomic Energy Agency, IAEA, Vienna, Austria.

 

4.   HISTORICAL BACKGROUND AND INFORMATION

The ENDF/B-VII data library, available from the National Nuclear Data Center (NNDC) at Brookhaven National Laboratory, was processed into the form of temperature dependent cross sections and are being distributed as POINT2009 by the Nuclear Data Section at IAEA, the National Nuclear Data Center (NNDC) at Brookhaven, the NEADB and RSICC. Details on this and previous versions of this library can be found in the included documentation.

 

5.   APPLICATION OF THE DATA

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. 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. CCC-638/TART2005 is recommended for use with these data. Codes within TART can be used to display these data or to run calculations using these data.

 

6.   SOURCE AND SCOPE OF DATA

      ENDF/B-VII.0 was released by CSEWG in November 2006 and is to be frozen for three years until November 2009. As such the Original data included in POINT 2009 is identical to that included in the earlier release POINT 2007 [RSICC ID: D00227/MNYCP/00]. However, the processed, temperature dependent results may differ because of improvements in the PREPRO ENDF/B Preprocessing Codes, particularly with regard to accuracy, and correct interpretation of the ENDF/B rules as defined by the ENDF/B formats and procedures manual, ENDF-102.

      POINT2009 contains all of the evaluations in the ENDF/B-VII.0 general purpose library. A table in the appendix summarizes the contents of this library, which contains evaluations for 393 materials (isotopes or naturally occurring elemental mixtures of isotopes). These evaluations include all cross sections over the energy range 10e-5 eV to at least 20 MeV. This library does not contain data from special purpose ENDF/B-VII libraries.

      The PREPRO2009 code system (soon to be released thru IAEA NDS) 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).

7.   DISCUSSION OF THE DATA RETRIEVAL PROGRAM

No data retrieval program is included in the package.  The PREPRO2009 codes may be used to plot the POINT2009 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 these data. The latest versions are available at NNDC http://www.nndc.bnl.gov/nndcscr/endf/endf-util/index.html.

 

8.   DATA FORMAT AND COMPUTER

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 11.5 gigabyte of storage. (D00239/MNYCP/00).
