The KAFAX-J33 is a MATXS-format, 150-group neutron and 12-group photon cross section library for fast reactors based on JENDL-3.3. This library was originally generated for the KALIMER (Korea Advanced LIquid MEtal Reactor) core analyses. It includes 136 nuclide data processed by the NJOY99.245 code patched with NEA020. The library can be utilized to generate the problem-dependent group constants for neutron and/or photon transport calculations through the DANTSYS, DOORS, or PARTISN code systems.

4. METHODS

The KAFAX-J33 was generated at 300, 600, 900, and 1200 K. It contains the self-shielded cross sections for 5 to 10 background cross sections depending on the nuclides. The neutron group structure consists of one-eighth lethargy widths in almost all the energy ranges, except between 1 and 10 keV in which one-sixteenth lethargy widths were used. The LANL 12-group structure (IGG=3) provided in the NJOY code was selected as a photon group structure. In the NJOY processing, an equilibrium core flux of the KALIMER-150 core was used as a weighting function. The background cross sections for a self-shielding were also selected from those of the calculations. The library has been validated through the fast benchmark experiments taken from the CSEWG benchmark specifications and BFS critical assemblies.
