FIELD: nuclear power engineering. SUBSTANCE: device has housing, which is filled with heat conducting liquid and is closed by cap with holes for load of assemblies, rotor which is located in housing and has sockets for assemblies, and at least one pressure branch pipe, which is connected to torsion box, which is located in housing and which upper part is connected to cap, and which lower part is located under level of heat conducting liquid. Branch pipe is connected to torsion box through gasket which provides gas passing between inner chamber of torsion box and housing chamber. Another claim of invention describes device design in which gasket has maze and deflecting plate which is located in expanding chamber which has channel for removal of leakage under level of heat conducting liquid. EFFECT: increased safety due to decreased output of vapor and splash of heat conducting liquid from housing. Сущность изобретения: устройство позволяет повысить безопасность путем уменьшения выхода теплоносителя из корпуса в виде паров и брызг. Барабан отработавших сборок ядерного реактора состоит из корпуса 1, ротора 2 с гнездами 3 для отработавших сборок 4, крышки 5 с отверстиями 6 для перегрузки и напорного патрубка 10. В корпусе выполнены по крайней мере два напорных патрубка 10, подсоединенных к кессону 11, верхняя часть которого прикреплена к крышке 5, а нижняя размещена под уровнем теплоносителя 7, при этом патрубок 10 подсоединен к кессону 11 через уплотнение 12. Уплотнение обеспечивает связь по газу полости кессона 11 с полостью 8 корпуса 1. Уплотнение может быть снабжено отбойным элементом 14, размещенным в камере 15 с каналом 17 для отвода протечек под уровень теплоносителя. 1 з.п. ф-лы. 2 ил.
