Abstract

Головка тепловыделяющей сборки с высоким поглощением энергии (10) для тепловыделяющей сборки с ядерным топливом, в которой используется удлиненный верхний трубчатый корпус (18) и удлиненный нижний трубчатый корпус (38), который может скользить в верхнем трубчатом корпусе (18). Верхний и нижний корпуса (18, 38) отталкиваются один от другого с помощью множества продольно вытянутых пружин (52, 54), которые удерживаются поршнем (32), способным двигаться в продольном направлении, движение которого вверх в верхнем корпусе (18) ограничено. Энергия, которая передается головке при аварийном сбрасывании контрольного стрежня, поглощается главным образом пружинами (52, 54) и гидравлическим действием поршня (32) внутри головки (10).
