Abstract

Изобретение относится к конструкциям легководных ядерных реакторов, в которых в качестве топлива применяется торий, в частности, к конструкциям бесчехловых тепловыделяющих сборок, из которых сформированы активные зоны водо-водяных энергетических реакторов, таких как реактор ВВЭР-1000. В активной зоне ядерного реактора, содержащей топливную сборку из запального и воспроизводящего модулей, сжигается ториевое топливо в воспроизводящем модуле вместе с обычным реакторным топливом, включающим непролиферативный обогащенный уран или энергетический плутоний в запальном модуле. Запальный модуль содержит пучок топливных элементов из обогащенного урана или энергетического плутония, при этом каждый топливный элемент имеет трехлепестковый профиль, образующий винтовые дистанционирующие ребра. Указанный пучок топливных элементов установлен в кожухе. Кожух с пучком топливных элементов запального модуля установлен в воспроизводящем модуле, который включает в себя силовой каркас с шестью продольными угловыми элементами и дистанционирующими решетками, имеющими в центральной зоне отверстие для расположения в нём кожуха запального модуля. В силовом каркасе расположен пучок топливных элементов, выполненных из тория с добавлением обогащенного урана. Опорная часть хвостовика воспроизводящего модуля выполнена с возможностью сопряжения с опорным стаканом легководного реактора. Запальный и воспроизводящий модули имеют в плане форму правильного шестиугольника. Также топливная сборка содержит головку с пружинным блоком для поджатия её к опорному стакану реактора и предотвращения всплытия топливных элементов при
