Настоящая работа посвящена разработке технологии исследования свойств облученного топлива реактора ВТГР. Объектом исследования являются топливные элементы реактора ВТГР. Топливные элементы содержат микротвэлы, представляющие собой сферическое трехструктурное изотропное топливо с внешним диаметром 0,92 мм. Микротвэлы имеют тройную оболочку из пироуглерода и карбида кремния. Микротвэлы спрессованы с графитовой матрицей в компакт.</p><p>В задачи исследований входят:</p><p>– внешний осмотр и анализ размеров топливного компакта;</p><p>– отделение микротвэлов от графитовой матрицы;</p><p>– определение доли поврежденных микротвэлов;</p><p>– определение выгорания урана.</p><p>Подобные исследования в институте проводятся впервые. Для реализации вышеописанных задач потребовалось разработать технологию обращения с облученным ядерным топливом. Полученные результаты будут применены для квалификации топлива ВТГР с целью дальнейшего увеличения глубины выгорания урана в нем.</p></abstract><trans-abstract xml:lang="en"><p>RSE “Institute of Nuclear Physics” of the Ministry of Energy of the Republic of Kazakhstan, together with the Atomic Energy Agency of Japan over the years have been conducting research aimed at developing the technology of a high-temperature gas-cooled reactor (HTGR). This paper is devoted to the development of technology to study the properties of the irradiated fuel of the HTGR reactor. The object of research is the fuel elements of the HTGR reactor. Fuel cells contain particles, which is a spherical three-structured isotropic fuel with an outer diameter of 0.92 mm. Particles have a triple coating of pyrocarbon and silicon carbide. Particles pressed with a graphite matrix in a compact.</p><p>The objectives of the research include:</p><p>– external inspection and analysis of the size of the fuel compact;</p><p>– separation of particles from the graphite matrix;</p><p>– determination of the proportion of damaged particles;</p><p>– determination of uranium burnout.</p><p>Such studies are conducted at the institute for the first time. To accomplish the above tasks, it was necessary to develop a technology for handling irradiated nuclear fuel. The results obtained will be used to qualify the HTGR fuel in order to further increase the burnup of uranium in it.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ВТГР</kwd><kwd>ВВР-К</kwd><kwd>топливо</kwd><kwd>микротвэл</kwd><kwd>выгорание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HTGR</kwd><kwd>WWR-K</kwd><kwd>fuel</kwd><kwd>particle</kwd><kwd>burnout</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Прогноз развития энергетики мира и России до 2040 года // ФГБУН «Институт энергетических исследований Российской академии наук», Аналитический центр при Правительстве Российской Федерации. – 2013.</mixed-citation><mixed-citation xml:lang="en">Прогноз развития энергетики мира и России до 2040 года // ФГБУН «Институт энергетических исследований Российской академии наук», Аналитический центр при Правительстве Российской Федерации. – 2013.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Рюль К.
