    摘要: Substantially pure uranium hexafluoride is shipped in a conventional overpack. A cylinder includes a vessel with a cylindrical sidewall A head permanently affixed to the sidewall closes one end of the vessel. A valve controls the flow of matter into and out of the vessel. A sealing surface connected to the vessel surrounds the valve. A cap covers the valve and a pair of seals is located between the sealing surface and the cap. The volume between the two seals, the cap and the sealing surface defines a test volume. A test port connects the test volume and an exterior surface of the vessel, and fasteners press the cap against the sealing surface. A maximum rate of leakage from within the cap to the atmosphere outside the cap is determined by measuring the leakage rate into the test volume with a leak testing apparatus connected to the test port. Thereafter the cylinder is placed in a conventional overpack. The maximum leakage rate is determined using a test apparatus consisting essentially of a vacuum pump, a pressure gauge, a container of known volume, a valve to control the flow of air from the atmosphere into the container which are all adapted to be connected to the test port at the same time, a valve controlling the flow of gas from the container into the test volume, and a valve controlling the flow of gas from the test volume to the vacuum pump.

    摘要: A vessel for the shipment of uranium hexafluoride includes a cylindrical wall closed by pair of approximately semi-ellipsoidal heads welded to form a sealed container. A service valve is located in one end. The valve is covered by a removable, watertight valve protection cover assembly. The vessel also includes a test port by means of which the integrity of the valve protection cover assembly may be tested after the cylinder has been filled with uranium hexafluoride and the valve protection assembly has been installed. The valve protection assembly is shaped so that it fits within the envelope of the standard 30B cylinders. The distal end of the valve protection assembly is recessed from a plane defined by the open end of the surrounding chime by at least one half inch, and preferably by ¾ inch or more. Accordingly, the fits within an overpack already approved by the NRC and used by shippers of uranium hexafluoride.

    摘要: A vessel for storing and transporting hazardous substances, like for example Uranium Hexafluoride, includes a body having an internal region that is subdivided into two or more isolated regions. The vessel further includes end members that house ingress and egress valves. A cover assembly is affixed to the vessel to shield the valves from damage due to exposure and/or impact.
