1. NAME AND TITLE OF DATA LIBRARY

PVE: 38 Group, P₈, Photon Interaction Cross Sections in ANISN Format from VITAMIN-E.

2. NAME AND TITLE OF DATA RETRIEVAL PROGRAMS

BCBN: Program to Convert from Card Image to ANISN Binary Form.

3. CONTRIBUTOR

Oak Ridge National Laboratory, Oak Ridge, Tennessee.

4. HISTORICAL BACKGROUND AND INFORMATION

PVE is based on the photon interaction data available in the DLC-113/VITAMIN-E package.

5. APPLICATION OF THE DATA

The data can be used in most discrete ordinates codes and in the CCC-203/MORSE-CG multigroup Monte Carlo code for photon radiation transport calculations.

6. SOURCE AND SCOPE OF DATA

This 38-group, P₈, library of photon interaction cross sections was derived from the photon interaction data in DLC-113/VITAMIN-E using the NITAWL and ALPO modules of the PSR-63/AMPX-II system. The original VITAMIN-E data were generated from DLC-99/HUGO using the SMUG module of AMPX-II. Data are provided for elements with atomic number in the range Z=1 to 100.

7. DISCUSSION OF THE DATA RETRIEVAL PROGRAM

A program called BCBN is provided in the package to convert the PVE data from ANISN card image to binary form which can then be used directly in most multigroup discrete ordinates codes.

8. DATA FORMAT AND COMPUTER

EBCDIC card images, Fortran IV; IBM-3033.

9. TYPICAL RUNNING TIME

Conversion of the entire library took 1.1 m on an IBM-3033.
