Abstract

Описаны кольцевое металлическое топливо и топливные стержни, которые имеют улучшенные характеристики по сравнению с топливными стержнями на основе оксида урана. Кольцевое металлическое топливо может быть изготовлено из пористого металлического ядерного топлива, генерирует больше энергии и работает при гораздо более низкой температуре, чем топливо на основе оксида урана. Кольцевые металлические топливные стержни могут использоваться в реакторах с бегущей волной и в других реакторах на быстрых нейтронах. Водо-водяные энергетические реакторы также могут быть оснащены кольцевыми металлическими топливными стержнями для улучшения эксплуатационных характеристик реактора.
