Данная модель имеет высокую степень детализации и позволяет проводить теплофизические расчеты параметров активной зоны в различных режимах ее работы, в том числе на предельных энерговыделениях и при возникновении нештатных ситуаций. Входными данными служат многомерные массивы с распределением энерговыделения по активной зоне, полученные после проведения нейтронно-физических расчетов. Результатом моделирования является массив данных, содержащий значения температуры, рассчитанные для каждого узла модели в каждый момент времени. При разработке теплофизической модели были реализованы новые нестандартные подходы, которые ранее не применялись. В данной работе показаны особенности моделирования активной зоны ИГР в среде ANSYS Mechanical APDL, которые позволили получить качественный инструмент для исследования температурных режимов реактора.</p></abstract><trans-abstract xml:lang="en"><p>To model thermal processes that occur in the core of the Impulse Graphite Reactor (IGR), the Institute of Atomic Energy of the RSE NNC RK uses a designed three-dimensional thermophysical model. This model has a high degree of detail and allows for thermophysical calculations of the core parameters in various modes of operation, including at maximum energy release and in the event of emergency situations. The input data are multidimensional arrays with the distribution of energy release in the core, obtained after neutronic calculations. The result of the modeling is an array of data containing the temperature values of each unit of the model at each moment in time. When designing the thermophysical model, new non-standard approaches were implemented that were not previously used. This paper shows the features of modeling the IGR core in the ANSYS Mechanical APDL environment, which made it possible to obtain a high-quality tool for studying the temperature modes of the reactor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ИГР</kwd><kwd>теплофизическая модель</kwd><kwd>метод конечных элементов</kwd><kwd>многомерный массив</kwd><kwd>ANSYS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>IGR</kwd><kwd>thermophysical model</kwd><kwd>finite element method</kwd><kwd>multidimensional array</kwd><kwd>ANSYS</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Данные исследования финансировались Министерством энергетики Республики Казахстан в рамках Научно-технической программы (BR24792713) «Развитие атомной энергетики в Республике Казахстан».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Vityuk V., Vityuk G., Vurim A., Irkimbekov R., Kukushkin I., Surayev A., Mukhamedov N.
