РАСЧЕТНОЕ ИССЛЕДОВАНИЕ РАДИАЦИОННЫХ ХАРАКТЕРИСТИК В НИШЕ ЭКСПЕРИМЕНТАЛЬНЫХ УСТРОЙСТВ РЕАКТОРА ВВР-К

Ядерный реактор – сложная инженерно-техническая установка, генерирующая излучение. Поэтому экспериментальные измерения радиационных характеристик ядерного реактора является сложной задачей, и в некоторых случаях технически невозможной. Современное развитие расчетных кодов и инструментов позволяет определить радиационные характеристики ядерного реактора с достаточной точностью и достоверностью. В связи с этим, компьютерное моделирование физических процессов, происходящих в ядерной реакторе, стало одним из основных методов научных исследований. Реактор ВВР-К это многоцелевой исследовательский реактор с большим количеством вертикальных и горизонтальных облучательных позиций, используемых для решения широкого круга научных и прикладных задач. Облучательная позиция с наибольшими размерами в реакторе ВВР-К представляет собой нишу для экспериментальных устройств, что позволяет проводить облучение объектов диаметром до 1000 мм. Данная позиция рассматривается в качестве кандидата для нейтронно-трансмутационного легирования слитков кремния диаметром более 200 мм. В статье представлены радиационные характеристики текущей и модернизированной конфигурации ниши экспериментальных устройств реактора ВВР-К. Показано, что усовершенствование конфигурации приводит к улучшение нейтронных характеристик в облучательной позиции.
