Abstract: This work focuses on the study of integral parameters of VVER-type critical experiment lattices of LWRs for VVER core calculations with the purpose of validation of the lattice transport code WIMSD-5B based on evaluated nuclear data files ENDF/B-VII and JENDL-3. These lattices are the standard benchmarks for testing reactor physics methods (codes) and libraries. The integral parameters of these lattices were calculated using WIMSD-5B based on the aforesaid libraries and were compared with the measured values as well as evaluated calculations of different libraries. It was found that in most cases, the values of integral parameters demonstrate a good agreement with the experiment values and evaluated calculations. This analysis reflects the validation of WIMSD-5B and associated libraries. Furthermore, the group constants' study also enriches this validation work. Therefore, this study is essential to implement further neutronics analysis and core calculations of the VVER reactors using same code and libraries.
