description: The work is devoted to the verification of the TDMCC code for calculating criticality of the nuclear assembles in the benchmark experiments with fast neutrons using the MCCNUC, ENDF/B-7.1, ENDF/B-8.0, JEFF-3.3, JENDL-4.0 evaluated nuclear data libraries. The research sets the following goals: 1. Studying of the theory basics of Monte Carlo method and of nuclear reactors. 2. Examining several experiments with fast neutrons from International handbook of evaluated criticality safety benchmark experiments which were used in the verification of the MCU-FR code. 3. Writing the input data files for the TDMCC code. 4. Calculation of multiplication factors for experimental assemblies from picked experiments and their analysis to identify the library with the most accurate data. The use of the TDMCC code and collection on it results were carried out in JSC Â«AtomenergoproektÂ». Calculations of multiplication factors based on 35 calculational models, confirming the possibility of using the TDMCC code with fast neutrons, and the analysis of them by determining evaluations of methodical errors, showing which library has the most accurate data, were performed. As a result, it turned out that the data in the ENDF/B-7.1 library is the most accurate, and the methodical errors for the MCCNUC, ENDF/B-7.1 and ENDF/B-8.0 libraries are close. Based on the carried studies, JSC Â«AtoenergoprojectÂ» decided to continue the verification of the TDMCC code with fast neutrons systems and to compare the MCU-FR and TDMCC codes in the future.
