Description

The purpose of the present work is to investigate the shape changes and void swelling in safety rod guide tubes of the reactors BN-350 and BOR-60 after operation for the scheduled life time. Authors show that the change of safety rod guide tube sizes occurs due to a non-uniform swelling of the material along tube wall height, perimeter and thickness

Abstract (Russian)

В работе исследовались формоизменение и распухание направляющих гильз стержней управления и защиты (СУЗ) реакторов БН-350 и БОР-60 после отработки ими заданного ресурса. Авторами показано, что деформация направляющих гильз стержней СУЗ происходит в результате неоднородного распухания материала гильз по высоте, периметру и толщине стенки
