Trans. of KNS Spring meeting , CD-ROM, 2009.
The BFS-1 critical facility was built at Institute of Physics and Power Engineering (IPPE) of Russia for benchmarking sodium cooled fast reactor cores. As a part of the cooperation program between Korea Atomic Energy Research Institute (KAERI) and IPPE, the BFS- 73-1 and BFS-75-1 critical assemblies were mounted in the BFS-1 critical facility to examine the KALIMER-150 fuels in 1997 and 1999. The average uranium enrichments of the two critical assemblies is 18.5 wt% that is similar to that of KALIMER-150. The analysis of the two core has been carried out by using the K-CORE and ECCO/ERANOS2.1 code system. The objective of this study is to analyze the BFS-73-1 and BFS-75-1 experiments with the Monte Carlo code of Seoul National University, McCARD
