    • 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.
    • 基本上纯的六氟化铀以传统的外包装运输。 圆柱体包括具有圆柱形侧壁的容器,永久地固定到侧壁的头部封闭容器的一端。 阀控制物质流入和流出容器。 连接到容器的密封表面围绕阀。 盖子覆盖阀门,一对密封件位于密封表面和盖子之间。 两个密封件之间的体积,盖子和密封表面限定了测试体积。 测试端口连接测试体积和容器的外表面,紧固件将盖子压靠密封表面。 通过使用连接到测试端口的泄漏测试设备测量进入测试体积的泄漏率来确定帽内部到帽外大气层的最大泄漏速率。 此后将圆筒放置在传统的外包装中。 使用基本上由真空泵,压力计,已知体积的容器组成的测试装置来确定最大泄漏率,用于控制从大气进入容器的空气流动的阀,所述阀都适于连接到 同时测试端口,控制从容器进入测试体积的气体流量的阀,以及控制从测试体积到真空泵的气体流量的阀。

    • 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.
    • 用于运输六氟化铀的容器包括由一对大致半椭圆形头封闭的圆柱形壁,其被焊接以形成密封容器。 维修阀位于一端。 阀门由可拆卸的水密阀门保护盖组件覆盖。 船舶还包括测试端口,通过该测试端口,可以在气瓶已经填充六氟化铀并且已安装阀保护组件之后测试阀保护盖组件的完整性。 阀门保护组件的形状使其适合标准30B气缸的外壳内。 阀保护组件的远端从由周围的钟声的开口端限定的平面凹进至少半英寸,优选地为¾英寸或更大。 因此,已经在NRC已批准并由托运人使用六氟化铀使用的外包装中。
