Abstract

Изобретение касается тепловыделяющей сборки для использования в активной зоне ядерного энергетического реактора. Сборка содержит каркас, имеющий форму и конфигурацию, подходящие для размещения каркаса во внутренней конструкции активной зоны ядерного реактора, и множество спирально закрученных тепловыделяющих элементов, находящихся в пучке тепловыделяющих стержней, поддерживаемых каркасом. Каждый из тепловыделяющих элементов содержит делящийся материал. На виде в разрезе, перпендикулярном осевому направлению тепловыделяющей сборки, самые внешние тепловыделяющие элементы пучка тепловыделяющих стержней образуют, по существу, круговой периметр. Описаны также другие особенности тепловыделяющей сборки и ядерный реактор.
