ABSTRACT:
A lifting assembly is configured to facilitate attaching of the lifting bar to a load bearing water rod in a nuclear fuel assembly. A connecting member is rigidly secured to the water rod and is provided with one of a male engaging portion and a female receiving portion. A lifting member including the lifting bar is engageable with the connecting member and includes the other of the male engaging portion and the female receiving portion. The male engaging portion and the female receiving portion are correspondingly shaped, and after insertion of the connecting member into or about the lifting member, the connecting member and lifting bar can be rotated relative to each other to prevent disassembly of the lifting assembly. A spring is disposed between the lifting bar and the water rod and urges the male engaging portion toward a locked position. The lifting assembly facilitates the attaching and detaching of the lifting bar to a load bearing water rod.
