Статья посвящена анализу существующих вариантов подреакторных ловушек расплава, конструкций и недостатков данных ловушек. Предложена вариация собственной подреакторной ловушки расплава с жаростойким композитным покрытием с кипящим слоем. Приведено описание установки для проведения экспериментальных исследований жаростойкого композитного покрытия с кипящим слоем. Приведены результаты теплового расчета вариации подреакторной ловушки расплава с кипящим слоем. Тепловой расчет показал, что увеличение средней температуры расплава проходит менее интенсивно в модели подреакторной ловушки с кипящим слоем, за счет теплоотвода от кориума к металлу на совершение фазового перехода.
