Abstract
A reactor vessel O-ring spring clip designed to hold the tubular O-ring in the groove of a reactor vessel head flange, especially during head lifting. The spring clip is designed such that the weight of the O-ring acts to increase the friction force between the spring clip and the, typically, threaded hole into which it is inserted. The end of the clip adapted to be inserted through a slot in the tubular O-ring for securement thereto has a circular member thereon which prevents the spring clip from becoming disengaged from the O-ring during head lifting.
