Description

Electronic data collection of the description of 2D and 3D models for the critical experiments realized in the ZR-6 critical assembly (Hungary) is developed. The program generating the source data for simulation of the assemblies using the MCU-RFFI/A program is prepared, and mathematical modelling for 154 configurations is made. Good agreement between the results of calculations and experiments is shown. When using two-dimensional models the value of the efficient multiplication factor averaged over 154 configurations amounts to 0.9989 ± 0.0034. For three-dimensional models the mean value of the efficient multiplication factor equal to 0.9994 ± 0.0023 is obtained for 13 assemblies. This value for the same assemblies in two-dimensional model amounts to 0.9987 ± 0.0030

Abstract (Russian)

Разработан электронный атлас описаний 2D- и 3D-моделей критических экспериментов, выполненных на сборке ZR-6 (Венгрия). Создана программа-генератор исходных данных для моделирования сборок по программе MCU-RFFI/A, и проведено математическое моделирование 154 конфигураций. Показано хорошее согласие результатов расчета и эксперимента. Для двумерных моделей среднее значение эффективного коэффициента размножения нейтронов по 154 конфигурациям равно 0,9989 ± 0,0034. Для трехмерных моделей на 13 сборках получено среднее значение эффективного коэффициента размножения, равное 0,9994 ± 0,0023. Для тех же сборок в двумерной модели эта величина составляет 0,9987 ± 0,0030
