Abstract
Активная зона ядерного реактора относится к области атомной энергетики. Активная зона ядерного реактора включает по меньшей мере один модуль, твёрдый (4) и жидкий замедлители нейтронов. Модуль содержит корпус (1), по меньшей мере одну тепловую трубу, по меньшей мере один тепловыделяющий элемент и теплоизоляцию (5). Тепловая труба выполнена в виде корпуса (2), снабжённого фитилём (6), и содержит теплоноситель. Тепловыделяющий элемент выполнен из ядерного топлива (8), расположенного в зоне испарения тепловой трубы вокруг её корпуса (2) в тепловом контакте с ним и заключённого в оболочку (3). В качестве теплоносителя тепловой трубы используют легкоплавкие металлы с высокой температурой кипения, например литий, кальций, свинец, серебро. Между оболочкой (3) и корпусом (1) модуля помещена теплоизоляция (5). В твёрдом замедлителе (4) нейтронов выполнено по меньшей мере одно отверстие, в котором размещён по меньшей мере один модуль. Пространство между корпусом (1) модуля и твёрдым замедлителем (4) нейтронов заполнено жидким замедлителем нейтронов. Технические результаты - повышение коэффициента полезного действия реакторных установок и расширение области применения активной зоны.
