На АЭС с ВВЭР она состоит из пассивных каталитических рекомбинаторов водорода. Расчет устройств имеет большое значение для обоснования безопасности, поскольку сложные условия аварии на энергоблоке невоспроизводимы в экспериментах. Рекомбинатор состоит из корпуса и кассеты c каталитическими элементами, конструкция которых обеспечивает прохождение газообразной среды через устройство. При контакте с катализатором происходит химическая реакция соединения водорода и кислорода, сопровождающаяся выделением теплоты, в результате концентрация водорода под оболочкой снижается. Проблемой является пуск из холодного состояния: активность холодного катализатора низка, а тяга не наблюдается до нагрева катализатора и формирования столба теплого газа внутри устройства. Переход из холодного состояния в рабочее занимает определенное время, в течение которого производительность рекомбинатора меньше номинальной. Время пуска – важный для безопасности параметр. В статье проведен расчет времени пуска рекомбинатора водорода с каталитическим блоком в форме эквидистантных параллельных каталитических пластин. Используются средние по местному сечению величины и коэффициенты передачи, последние учитывают влияние свободной конвекции и химической реакции. Скорость газа определяется по балансу сил плавучести и сопротивления. Расчетные и известные из научно-технической литературы данные совпадают удовлетворительно. В качестве консервативной оценки времени пуска рекомбинатора рекомендуется использовать величину 300 с. Рост температуры практически не влияет на запуск рекомбинатора с активным катализатором, повышение концентрации водорода ускоряет запуск, понижение давления его замедляет. Полученные результаты могут использоваться при обосновании безопасности АЭС с ВВЭР и экспертизе отчетов по обоснованию безопасности энергоблоков.</p></abstract><trans-abstract xml:lang="en"><p>The hydrogen removal system ensures hydrogen safety. At a VVER nuclear power plant, it consists of passive catalytic hydrogen recombiners. The calculation of devices is of great importance for safety justification, since the complex conditions of an accident at a power unit are not reproducible in experiments. The recombiner consists of a casing and a cassette with catalytic elements, the design of which ensures the passage of a gaseous medium through the device. Upon contact with the catalyst, a chemical reaction of hydrogen and oxygen compounds occurs, accompanied by the release of heat; as a result, the concentration of hydrogen under the shell decreases. The problem is starting from a cold state since the activity of the cold catalyst is low, and the thrust is not observed until the catalyst is heated and a column of warm gas is formed inside the device. The transition from the cold state to the working state takes a certain time, during which the recombiner performance is below nominal. The start-up time is a parameter that is important in terms of safety. The article calculates the start-up time of a hydrogen recombiner with a catalytic block in the form of equidistant parallel catalytic plates. Local cross-sectional averages and transmission coefficients are used, the latter taking into account the influence of free convection and chemical reaction. The gas velocity is determined by the balance of buoyant and resistance forces. The calculated data and the data known from the scientific and technical literature coincide satisfactorily. As a conservative estimate of the start-up time of the recombiner, it is recommended to use the value of 300 s. An increase in temperature practically does not affect the start of the recombiner with an active catalyst, an increase in the concentration of hydrogen accelerates the start, and a decrease in pressure slows it down. The results obtained in the study can be used in the justification of the safety of VVER nuclear power plants and the examination of reports on the justification of the safety of power units.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>АЭС</kwd><kwd>ВВЭР</kwd><kwd>водородная безопасность</kwd><kwd>пассивные каталитические рекомбинаторы водорода</kwd><kwd>время пуска</kwd><kwd>расчеты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nuclear power plant</kwd><kwd>VVER</kwd><kwd>hydrogen safety</kwd><kwd>passive catalytic hydrogen recombiner</kwd><kwd>start-up time</kwd><kwd>calculations</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">Исследование локальной гидродинамики теплоносителя в смешанной активной зоне реактора ВВЭР / С.
