ABSTRACT

The initial LEU (IRT-4M fuel assemblies, 19.75% 235U) core of the new IRT-Sofia research reactor of the Institute for Nuclear Research and Nuclear Energy (INRNE) of the Bulgarian Academy of Science, Sofia, Bulgaria is jointly analyzed with the RERTR Program at Argonne National Laboratory (ANL) to evaluate its performance and other important characteristics for safety analyses. The initial configuration using 16 fuel assemblies (four 8-tube and twelve 6- tube fuel assemblies) detailed power distributions and beam tubes flux performance for two critical core states corresponding to different control rods positioning, and different performance characteristics are compared. Results of calculations for two configurations at the beginning of the second operation cycle using 17 fuel assemblies (sixteen burned fuel assemblies (FA) and one fresh 6-tube FA) are presented. The results provide important and useful information for safety analyses and performance of the future reactor operation.
