The verification of the method for acceleration the calculation of slow transition xenon processes based on the use of the similarity theorem were done in this paper. For this purpose experiments with spatial xenon oscillations were calculated by using this method. Two experiments were considered in this work: in the first experiment initiation of xenon oscillations was realized by injection of boron acid in primary circuit and following reactor plant power decreasing, in the second experiment initiation of xenon oscillations was realized by control rod group movement. The calculation results were compared with calculation results of analogical experiments without using calculation acceleration method and experimental data. Additionally calculations of daily maneuvering cycle with electrical power level changing on graph 100-70-100 % Nnom and using calculation acceleration method were performed. These calculations were done for AES-2006 project VVER reactor plant. The calculation results were compared with calculation results of analogical daily maneuvering cycle without using calculation acceleration method. Some conclusions on the possibility of using the calculation acceleration method for calculations of long-term xenon processes were made. The calculations were performed by using KORSAR/GP code.
