  ORIGIN: JEF-2.2

  WEIGHTING SPECTRUM: Thermal + 1/E + fast reactor + fusion
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The library is focused on the fast reactor analyses. It has 80 and 24 energy group structures for neutron and photon, respectively. It includes 97 nuclide data based on JEF-2.2 and has a format of MATXS processed by the NJOY94 code. It can be used to calculate the problem dependant group constants with the TRANSX code for neutron and gamma transport.

4. METHODS

The data were generated at 300 ~ 2500 Kelvin degrees and at 4~7 background cross sections for the self shielding considerations. The weighting function used for group averaged neutron cross sections from the pointwise data is " thermal + 1/E + fast reactor + fusion". The library has been validated through the CSEWG benchmark analyses such as VERA-11A, ZPR-3-12, SNEAK-7B, ZPPR-2, ZPR-6-7, etc.
