В статье представлены результаты экспериментов по измерению температуры образцов конструкционных материалов, подвергнутых радиационному разогреву в условиях импульсного облучения на исследовательском реакторе ИГР. Для регистрации температуры разработано внутриреакторное экспериментальное устройство, состоящее из защитной ампулы с максимально разреженной средой, внутри которой размещались исследуемые образцы. Термопары интегрированы непосредственно в структуру образцов, с целью измерения температуры внутри материала. Исследованы температурные отклики 12 материалов, включая тугоплавкие металлы, высоколегированные стали и алюминиевые сплавы. Установлены характерные закономерности нагрева, отражающие влияние физических и радиационных свойств материалов. Полученные данные актуальны для верификации теплотехнических моделей и повышения точности расчетов при проектировании оборудования для ядерных установок.

The paper presents experimental findings on the temperature measurement of structural material samples exposed to radiation heating during pulsed irradiation at the IGR research reactor. To record the temperature, an in-pile experimental device was specifically designed, consisting of a protective ampoule with an ultra-low-pressure environment to house the test samples. Thermocouples were embedded directly into the sample structures to enable precise temperature measurements within the materials. Temperature responses in 12 materials have been examined, including refractory metals, high-alloy steels, and aluminum alloys. Distinct heating patterns were identified that influenced by their physical and radiation properties of the materials. These results provide valuable data for refining thermal engineering models and enhancing the accuracy of calculations in the design of equipment for nuclear installations.
