Abstract

Предложен элемент для ядерных реакторов, который может стабильно использоваться без распухания или деформации ползучести даже при прямом воздействии нейтронов, без каких-либо дополнительных улучшений эксплуатационных условий и устройств ядерного реактора. Элемент для ядерных реакторов содержит центральную секцию, содержащую совокупность твердых частиц графита и покрывающий слой, содержащий керамическое плотное тело, которое покрывает центральную секцию. Поскольку графит, подвергаемый облучению нейтронами, используется в виде совокупности твердых частиц, которые не связаны взаимно, форма и размеры элемента для ядерных реакторов не нарушаются даже при распухании, деформации ползучести или др. Кроме того, данный элемент для ядерных реакторов имеет покрывающий слой, содержащий плотную оболочку из керамики, покрывающую центральную секцию. Поскольку покрывающий слой, содержащий плотную оболочку, более устойчив, чем графит, к облучению нейтронами, снижается вероятность нарушения формы и размеров элемента для ядерных реакторов.
