ABSTRACT:
A single insert is provided with a plurality of curved channels extending therethrough. Such insert allows passage of a relatively large number of cables through a relatively small area of a pressure vessel wall, and the curvature of the channels prevents a straight line path for gamma radiation. The curvature of the channels (i.e. their radius) exceeds the design minimum bend radius for cables that will be passed through the insert. The ends of the insert are conical in shape to provide increased spacing for gland nuts secured in the ends of the channels.
