Description

The paper describes the refinements of the design model of the SM reactor. The division of beryllium into separate zones with the same nuclide composition has been clarified. An optimal list of nuclides for calculations was selected, and the effect of thermal expansion of materials on reactivity was investigated. The approach used by the authors is applicable to other models of research reactors

Abstract (Russian)

В работе описаны проведенные уточнения расчетной модели реактора СМ. Уточнено разбиение бериллия на отдельные зоны с одинаковым нуклидным составом. Отобран оптимальный для проведения расчетов список нуклидов и исследовано влияние теплового расширения материалов на реактивность. Использованный авторами подход применим к другим моделям исследовательских реакторов
