Работа ориентирована на решение реальных задач реактора ВВЭР. Решается проблема моделирования ТВЭЛа и ТВЭЛа с гадолинием в ВВЭР, а именно, анализируется на какое количесвто расчётных слоёв необходимо разбивать топливный стержнь и топливо с гадолиниевым стержнием. Работа содержит зависимость отклонения коэффициента размножения нейтронов от выгорания. Для решения данных задач использовались программы GETERA-93 и WIMS. Для подготовки данных была использована SIMPLE FORTRAN.

This work is focused on solving real problems of a WWER reactor. The problem of simulating a fuel rod and a fuel rod with gadolinium in WWER is solved, exactly, it is analyzed for how many design layers is necessary in the fuel rod and fuel with gadolinium rod. The work contains the dependence of the deviation of the multiplication factor of neutrons from burnout. To solve these problems, the GETERA-93 and WIMS programs are used. SIMPLE FORTRAN was used for data preparation.
