<p>The invention relates to a control rod insertable into a guide thimble of a nuclear fuel assembly to provide xenon compension.
<??>The control rod (32) consists of a rod-like inner member (34) and a tubular outer member (36) each composed of alternating poison regions (38,42) and non-poison regions (40,44). The rod-like inner member (34) extends axially through the tubular outer member (36), and one of the two members is axially movable relative to the other such as to vary the degree of overlap between the respective poison and non-poison regions of the two members and thereby change the overall worth of the control rod.</p> |
