Computational study of physical processes in the IGR reactor with using the PRIZMA.D code

The possibility for calculational study on physical processes in the IGR pulse uranium-graphite reactor core through the PRIZMA.D program with application of the correlation results in multivariant calculations is shown by example of one of the experiments. It is shown that the methodology, whereby the correlation results are obtained in one calculational task for multiple configurations, makes it possible to forecast reliably small experimental effects, starting with the percent fractions. The multivariant calculation for the task under consideration proved to be by 90 times more efficient as compared to the series of independent calculations
