Испытания проводились на стенде ФТМ-2023 НГТУ в свинцовом теплоносителе с температурой до 430—450 °С, без циркуляции. Трубный пучок для моделирования течи парогенератора при истечении лёгкой фазы представляет собой два ряда труб 22×3,5 приваренных к пластине с шагом в 33 мм. Данные получены для трубных пучков с двумя разными видами отверстий для истечения паровой фазы: щелевое отверстие 13х1 мм и круглое отверстие диаметром 4 мм. Обработка и анализ результатов позволили сделать вывод о том, что при попадании пароводяной смеси в контур ТЖМТ происходит утонение оксидных покрытий в зависимости от места расположения трубки в пучке и от формы отверстия истечения. Происходит заметное уменьшение микротвёрдости (на 49 HV для трубного пучка с круглым отверстием истечения и на 23 HV для трубного пучка с прямоугольным отверстием истечения), что проявляется сильнее при приближении к отверстию истечения и зависит от ориентации поверхности трубки, на которую попадает смесь, относительно неплотности. Полученные данные рекомендуется использовать при оценке последствий большой течи парогенератора горизонтального исполнения в установках с ТЖМТ.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of experimental studies of the durability of protective oxide coatings of 12X18N10T stainless steel in a lead coolant environment, when simulating an emergency situation of “inter-circuit leakage of a steam generator”. The tests were carried out on the FTM-2023 NSTU stand in a lead coolant with a temperature of up to 430—450 °C, without circulation. The tube bundle for simulating a steam generator leak during the outflow of the light phase is two rows of 22x3.5 pipes welded to a plate with a pitch of 33 mm. The data were obtained for tube bundles with two different types of holes for the outflow of the vapor phase: a slit hole of 13x1 mm and a round hole with a diameter of 4 mm. The processing and analysis of the results allowed us to conclude that when a steam-water mixture enters the HLMC circuit, the oxide coatings become thinner depending on the location of the tube in the bundle and the shape of the discharge hole. There is a noticeable decrease in microhardness (by 49 HV for a tube bundle with a round discharge hole and by 23 HV for a tube bundle with a rectangular discharge hole), which is more pronounced when approaching the discharge hole and depends on the orientation of the tube surface onto which the mixture enters, relative to the leak. The obtained data are recommended for use in assessing the consequences of a large leak in a horizontal steam generator in installations with heavy liquid metal coolant.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>течь парогенератора</kwd><kwd>свинцовый теплоноситель</kwd><kwd>горизонтальный парогенератор</kwd><kwd>износ оксидного покрытия</kwd><kwd>микротвердость</kwd><kwd>трубная решетка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>steam generator leak</kwd><kwd>lead coolant</kwd><kwd>horizontal steam generator</kwd><kwd>oxide coating wear</kwd><kwd>microhard-ness</kwd><kwd>tube sheet</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">Chauthwani G.C. and Kannan U.
