4.         NATURE OF PROBLEM SOLVED

The LLNL Evaluated Nuclear Data Library has existed since 1958 in a succession of forms and formats. The data included here is a binary file, ENDL2011, containing the pointwise continuous neutron cross-sections from the 2011 version of the library as formatted for use in the LLNL COG code.

The Evaluated Nuclear Data File has existed since 1968 and is maintained by the National Nuclear Data Center located at Brookhaven National Laboratory. The data included here are three binary files: MCNP.71nc containing the point-wise continuous cross-sections; PT.MCNP.71nc containing the probability tables for the unresolved resonance region; and, T.MCNP.71nc containing thermal scattering data, respectively, from the ENDF/B-VI I.1 version of the library as originally distributed by Los Alamos National Laboratory with the MCNP6.1 code package but reformatted here for use in the LLNL COG code.

5.         APPLICATION OF THE DATA

Libraries provided to facilitate code inter-comparisons between COG and other codes using these data libraries.

6.         SOURCE AND SCOPE OF DATA

The COG supplemental data libraries were prepared using RSICC Code Package PSR-607 for use with RSICC Code Package CCC-777.

7.         DISCUSSION OF THE DATA RETRIEVAL PROGRAM

Described in documentation provided in RSICC Code Packages PSR-607 and CCC-777.

8.         DATA FORMAT AND COMPUTER

Binary files compatible with PC, MAC and UNIX 32-bit and 64-bit machines.

9.         TYPICAL RUNNING TIME

Not stated.
