This work was fulfilled in the frame of JNC-IPPE Collaboration on Ex- perimental investigation of Excess Weapon Pu Disposition in BN-600 re-actor Using BFS-2 Facility. Data processing system CONSYST/ABBN cou- pled with ABBN-93 nuclear data libraty was used in analysis of BFS-62 and ZPPR JUPITER series fast reactor cores, applying JNC core calcu- lation code CITATION-FBR. FFCP cell code was used for taking into ac- count the spatial cell heterogeneity and response effect based on the first Flight collision Probability method and subgroup approach. Espe-cially two converting programs were written to transmit the prepared effective cross section to JNC standard PDS files to let then the CI- TATION code be applied for 3-D HEXZ neitronics calculation of the in- vestigated cores. The effects of nuclear data library have been stu- died by comparing the results calculated using ABBN-93 nuclear data library with the former ones obtained in JNC based on JENDL-3.2 nucle-ar data library.

This work was fulfilled in the frame of JNC-IPPE Collaboration on Experimental Investigation of Excess of Weapon Pu Disposition in BN-600 Reactor using BFS-2 Facility. The data processing system CONSYST/ABBN coupled with ABBN-93 nuclear data library was used in analysis of BFS and ZPPR fast reactor cores applying JNC core calculation code CITATION. FFCP cell code was used for taking into account the spatial cell heterogeneity and resonance effects based on the first flight collision probability method and subgroup approach. Especially a converting program was written to transmit the prepared effective cross sections to JNC standard PDS files. Then the CITATION code was applied for 3-D XYZ neutronics calculations of BFS and ZPPR JUPITER experiments series cores. The effects of nuclear data library have been studied by comparing the former results based on JENDL-3.2 nuclear data library. The comparison results using IPPE and JNC nuclear data libraries for k-effective parameter for ZPPR-9, ZPPR-13A and ZPPR-17A cores are presented. The calculated correction factor in all cases was less than 1.0%. So the uncertainty in C value caused by possible errors in calculation of these corrections is expected to be less than 0.3% in case of ZPPR-13A and ZPPR-17A cores, and rather less for ZPPR-9 core. The main result of this study is that the effect of applying ABBN-93 nuclear data in JNC culculation route revealed a large enough discrepancy in k-eff for ZPPR-9 (about 0.6%) and ZPPR-17A(about 0.5%) cores. For BFS-62-1 and BFS-62-2 cores such analysis is in progress. Stretch cell models for both BFS cores were formed and cell calculations using FFCP code have started. Some results of cell calculations are presented.
