Description

Results of calculated neutron characteristics of BIR and BIGR fast pulse reactors, namely, cylindric systems with the core zone involving 90 %- and 36 % uranium enriched alloy with 10 % by mass of molybdenum or composite uranium-graphite material are presented. Neutron characteristics of the reactors were calculated by means of the S-95 code by the Monte Carlo method with the aim of possible increasing inner cavities in the reactors without pronounced degradation of time parameters of impulses. Disk reactor core systems with the axial cavity by the diameter to 30 cm and iron reflector limited by the width are the most acceptable

Abstract (Russian)

Приведены результаты расчетов нейтронных характеристик быстрых импульсных реакторов типа БИР и БИГР, а именно цилиндрических систем с активной зоной из сплава урана 90 %- или 36 %-ного обогащения с 10 % по массе молибдена или композитного уран-графитового материала. Нейтронные харктеристики реакторов рассчитывали с помощью программы С-95 метода Монте-Карло с целью возможного увеличения внутренних полостей в реакторах без заметного ухудшения временных параметров импульсов. Наиболее приемлемыми признаны системы с дисковой активной зоной, имеющей осевую полость диаметром до 30 см и ограниченный по толщине железный отражатель
