Технология основана на применении однородного укороченного плазменного разряда в инертном газе (аргон) для ионной и термической обработки одновременно всех поверхностей графитового блока в специальной камере. Дезактивация графитового блока кладки реактора осуществляется посредством ионного распыления радионуклидов с его поверхностей, а также за счет их термодиффузии из объема блока благодаря нагреву плазменным разрядом. При этом технология позволяет сохранить интегральную целостность дезактивированных блоков графитовой кладки реактора для эффективного захоронения. В статье получены теплофизические параметры ионно-плазменной камерной технологии на примере дезактивации реакторного графита марки ГР-280.</p></abstract><trans-abstract xml:lang="en"><p>A new “dry” ion-plasma chamber deactivation technology is developed for the first time to deactivate irradiated graphite blocks. The technology is based on a homogenous shortened plasma discharge in an inert gas (argon) for the ion and thermal treatment of all graphite block surfaces simultaneously in a special chamber. The deactivation of graphite block of the reactor masonry is carried out by the ion sputtering of radionuclides from the block surfaces, as well as due to the thermal diffusion of radionuclides from the graphite block volume under plasma discharge heating. The technology provides a maintenance of the graphite masonry blocks integrity during the deactivation process for the effective burial of radionuclides. The thermophysical parameters of the ion plasma in chamber technology for the deactivation of the grade GR-280 reactor graphite have been obtained.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ионно-плазменная технология дезактивации в камере</kwd><kwd>ядерные энергетические установки</kwd><kwd>дезактивация</kwd><kwd>облученный реакторный графит</kwd><kwd>вывод из эксплуатации</kwd><kwd>реактор большой мощности канальный</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ion plasma chamber deactivation technology</kwd><kwd>nuclear power plants</kwd><kwd>deactivation</kwd><kwd>irradiated reactor graphite</kwd><kwd>nuclear plant decommission</kwd><kwd>high-power channel-type reactor</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 24-29-00321, https://rscf.ru/project/2429-00321/.</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">Gurau D., Deju R. // Radiat.
