С использованием программного комплекса MCNP выполнены расчеты уран-водного соотношения, распределений удельного энерговыделения в твэлах и средней удельной мощности по высоте активной части топлива. Проведен анализ влияния конструктивных особенностей одностенных и двустенных облучательных устройств на нейтронно-физические характеристики топлива. Установлено, что применение облучательного устройства ID-M приводит к снижению среднего уровня удельного энерговыделения приблизительно на 45% по сравнению с устройством WF. Сопоставление расчетных характеристик облучательных устройств с параметрами реакторов ВВЭР-1000, APR-1400 и HPR-1000 показало возможность воспроизведения в реакторе ИГР, в течение 100–200 с, уровней энерговыделения, характерных для эксплуатации топлива энергетических реакторов. Полученные результаты могут быть использованы при подготовке внутриреакторных испытаний перспективного ядерного топлива, оценке тепловых режимов и обеспечении безопасности экспериментальных исследований.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of computational neutron-physical modeling of irradiation devices ID-M and WF containing fuel from VVER-1000, APR-1400, and HPR-1000 reactors and placed within the central experimental channel of the IGR reactor. Using the MCNP code system, calculations of the uranium-water ratio, specific power generation distributions in fuel rods, and average specific power along the active fuel height were performed. An analysis of the influence of the design features of single-wall and double-wall irradiation devices on the neutron-physical characteristics of the fuel was carried out. It was established that the use of the double-wall ID-M irradiation device results in approximately a 45% reduction in the average specific power generation level compared to the single-wall WF device. Comparison of the calculated characteristics of the irradiation devices with the corresponding parameters of VVER-1000, APR-1400, and HPR-1000 reactors demonstrated the possibility of reproducing in the IGR reactor power generation levels characteristic of fuel operation in commercial power reactors. The obtained results can be applied to the preparation of in-reactor testing of advanced nuclear fuels, thermal regime assessment, and safety assurance of experimental investigations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нейтронно-физическое моделирование</kwd><kwd>облучательные устройства</kwd><kwd>ИГР</kwd><kwd>энергетический реактор</kwd><kwd>энерговыделение</kwd><kwd>удельная мощность</kwd><kwd>MCNP</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neutron-physical modeling</kwd><kwd>irradiation devices</kwd><kwd>IGR reactor</kwd><kwd>VVER-1000</kwd><kwd>APR-1400</kwd><kwd>HPR-1000</kwd><kwd>power generation</kwd><kwd>specific power</kwd><kwd>MCNP</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа была выполнена при поддержке Комитета науки МНВО РК в рамках грантового проекта «Расчетное обоснование режимов внутриреакторных испытаний перспективного ядерного топлива» (ИРН AP26199863)</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">Компьютерная модель реактора ИГР для стационарных нейтронно-физических расчетов: а. с.
