A shipping container comprises a tubular or cylindrical shell having a closed end and an open end, a top end-cap removably secured to the open end of the tubular or cylindrical shell, and at least one fuel assembly compartment defined inside the shell. Each fuel assembly compartment includes elastomeric sidewalls and is sized and shaped to receive an unirradiated nuclear fuel assembly through the open end of the shell. The shipping container may further include a divider component, for example having a cross-shaped cross-section with ends of the cross secured to inner walls of the shell, and the divider component and the inner walls of the shell define the fuel assembly compartments. To load, the shipping container is arranged vertically and an unirradiated nuclear fuel assembly is loaded through the open end of the shell into each compartment, after which the open end is closed off by securing the top end-cap.

An on-line sipping air delivery system that propels bubbles across the entire surface of the fuel assembly. A pump delivers liquid through an aspirator located near the bottom of the fuel handling mast. Liquid flow through a venturi in the aspirator causes a drop in pressure inside the aspirator and pulls air into the aspirator through an ambient air line that extends above the surface of the liquid. The air is mixed with liquid as it flows through the aspirator and the mixture is injected under the fuel assembly through nozzles positioned at the bottom of the assembly. Suction nozzles above the liquid level at the top of the fuel assembly are used in a conventional manner to capture and deliver the released air and gases to appropriate testing equipment.
