ABSTRACT:
A cask for containing spent nuclear fuel during transport. The cask has a pair of multiple element trunnions disposed on opposite sides of the cask adjacent the top thereof. The multiple elements of the trunnions provide separate and independent load paths for lifting the cask. The trunnions are removable and disassemblable to permit inspection of each element. Disposed on the ends of the cask are convex impact limiters for reducing forces applied to the cask in a collision. Apparatus engageable with the trunnions for lifting the cask thereby comprise a pair of multiple element laminated plates engageable with a crane hook. A pair of multiple element straps have ends selectively engageable with the plates and ends selectively engageable with the trunnions of the cask.
