A mechanical device for grasping an object includes a receiver having a distal end shaft with an internal bore, the internal bore defining a recessed track. The recessed track defines a curvilinear path having two sets of resting peaks, each set of resting peaks being at a different height relative to a centerline of the curvilinear path. An actuator is slidably engaged with the receiver and includes a central shaft and an activator disposed at a distal end portion of the central shaft. A rotatable sleeve is disposed within the internal bore of the receiver and is coupled to the actuator. The rotatable sleeve has opposed protrusions, the opposed protrusions being disposed within the recessed track of the receiver. A pilot is secured to a distal end portion of the receiver and a grasping device is mounted to the pilot and coupled to the activator.

Disclosed is nuclear reactor fuel rod for use in a nuclear reactor. The nuclear reactor fuel rod comprises a sleeve defining a longitudinal axis. The sleeve includes a first end portion and a second end portion. The nuclear reactor fuel rod further includes a first end cap mechanically coupled to the first end portion of the sleeve and a second end cap mechanically coupled to the second end portion of the sleeve. The second end cap is configured to slide along the longitudinal axis relative to the sleeve. The nuclear reactor fuel rod further includes a fuel compact located inside of the sleeve between the first end cap and the second end cap.
