Anchor assembly for fuel bundle

摘要

Anchor assembly apparatus for improving the structural integrity of a guide tube (26) in a nuclear fuel bundle (20). A sleeve (100) has a proximate end (102) and a distal end (104) that is adapted for insertion into a receiving end (38) of the guide tube. A pin (140) has a near end (142) and a far end (144) adapted for insertion into the sleeve at the sleeve's proximate end. The pin has an external surface (148) that applies a radial force to an inner surface (118) of the sleeve when the pin is inserted into the sleeve. The force is sufficient to cause a locking surface (120) on the sleeve to expand radially outward.
