Abstract

MONTE CARLO CALCULATIONS OF VVER-440 AND VVER-1000 FULL-SCALE CORES BY MCU CODED.S. OleynikNational Research Centre “Kurchatov Institute”, Russia, MoscowABSTRACTBecause of the restricted experimental data of power distribution due to design codes’ verification Monte Carlo codes it is taken advantage of Monte Carlo codes. These codes simulates the interaction of radiation with substance on the basis of the information from files of the evaluated nuclear data (i.e. the most exact data without additional assumptions is used). Besides, this method practically does not impose restrictions on the geometry of considered systems.In the frame of AER group the calculation benchmarks of VVER-440 and VVER-1000 full core are prepared for reliability validation of design codes. These benchmarks are calculated by means of MCU (Monte Carlo Universal) code. The results of the calculations are presented in the paper.26th Symposium of AER on VVER Reactor Physics and Reactor Safety 9 10 – 14 October 2016, Helsinki, Finland
