Availability of Additional ENDF/B-VI Nuclear Data

This memorandum announces the release of the following ENDF/B-VI tapes for general use at ORNL. 
They are:

       ENDF/B-VI Tapes 120-124,        Revision 1 of Neutron Sublibrary
       ENDF/B-VI Tapes 125-126,        Neutron Fission Product Yield Sublibrary
       ENDF/B-VI Tape  209,            Spontaneous Neutron FP Yield Sublibrary
       ENDF/B-VI Tapes 300, 320, 340,  Charged Particle Sublibraries
       ENDF/B-VI Tapes 200-208,        Radioactive Decay Data Sublibrary.

Tapes 120-124 contain corrections to the neutron sublibrary and as such should supersede the
corresponding evaluations in Tapes 100 through 117.  We are still expecting a corrected version of the
thermal scattering law sublibrary for graphite.  The other tapes are new releases of the specialized nuclear
data cited above.  (For example, tapes 200-208 contain the complete decay data sublibrary.)  The contents
of the various ENDF/B-VI Tapes are given in the enclosures.

In addition to the X-tapes on the IBM 3090 mainframe, users can now access all ENDF/B-VI data via
a workstation or other computers.  Please send your IP host address to B.L. Kirk via email at
pdc@ornlstc if you wish workstation access to the ENDF data.  Users will be able to gain access to the
data through NFS.  The file naming convention will follow the ENDF tape designation (e.g., ENDF/B-VI
Tape 100 will be t100, etc.).

RSIC has received several copies of the revisions to ENDF-102 dated October 1991.  Holders of
ENDF-102 can contact me for a copy of the changes (~61 pages).

These evaluations are being released with no restrictions on their distribution or use.  The National
Nuclear Data Center at Brookhaven National Laboratory requests that all users report results obtained
when testing and intercomparing benchmark results using this data.

Please contact me if you have any questions about ENDF/B-VI data.
