Abstract

A channel spacer for separating the channels in the core of a nuclear reactor is proposed. Four channels are arranged adjacent to one another in a single cell, and each has a spacer of this kind with arms which are supported on the spacers of the adjacent channels. The lower tips of the arms can be inserted into openings in the sides of the channels. <IMAGE>
