RSICC received these data from the NEADB where they are distributed
with identifier NEA-1768 ZZ-MCJEFF3.1NEA. In the DB collection each
temperature is distributed as a separate package (versions 01 through 11).
RSICC made no changes but distributes all temperatures in one package.

This package contains the ACE format library of all scattering materials
of the JEFF-3.1 library at different temperatures.

Libraries for the other cross sections for different temperatures (300, 
400, 500, 600, 700, 800, 900, 1000, 1200, 1800 Kelvin) are provided as 
separate zip files. 

Updates required for processing JEFF-3.1 with NJOY99.90 are provided 
as a separate set of patch files.  The NJOY99 manual and the UPD utility 
should be used to apply them. The NJOY99 package is available from 
both RSICC and the NEADB.

NJOY99.90 inputs used for processing each material are provided.

Data for each temperature are provided in ascii format. In addition,
the xsdir file is provided for both ascii and binary file.

Documentation is provided including results from benchmark tests for 
criticality (ICSBEP) and shielding (SINBAD).
