Embodiment Construction

[0020] If no additional support is provided, such as that provided by a transport cask, the nuclear fuel assembly needs to be moved into a vertical orientation so that the fuel rods and guide thimbles do not bend. However, due to the long dimension of the outer packaging 12, a single fuel assembly transport packaging apparatus, such as the TRAVELLER 10 shown in Figure 1, will be more stable if transported in a horizontal orientation. Therefore, a transport packaging device, such as the TRAVELLER 10, needs to be turned upright for loading and unloading. A reusable tipping device 24 constructed in accordance with the present invention is used to facilitate the loading and unloading of nuclear fuel packages. figure 2 The turning device 24 shown in is a structural component having a translating base 26 mounted on a fixed beam structure 28 . The mobile base 26 has at least two stabilizing or support arms 30 and 32 which are bolted to fixed supports 36 located at the rear and secur...

Abstract

A reusable up-ending device for loading or unloading nuclear fuel assembly shipping packages. The device has a translating base mounted to a fixed beam structure and two stabilizing arms affixed to a mounting fixture on the base that is secured to the operating floor. The stabilizing arms include a spring dampener and have a simple elbow joint that straightens after the package is up righted. Translation is achieved by means of a hand adjustable lead screw and enables the base to be most advantageously positioned. The shipping package is inserted into pivot mount blocks located at the front of the base and the package is secured at the pivot mount blocks by means of a trunnion and at the support arms by means of a locking pin. Once the package is up-righted the elbows on the support arms are locked in place.

Description

technical field [0001] The present invention generally relates to a handling device for transport containers for nuclear fuel components, and more particularly to an inverting device for smoothly moving such transport containers between horizontal and vertical orientations. Background technique [0002] During the transport and storage of non-irradiated nuclear fuel elements and assemblies containing large and / or concentrated fissile material U235, it must be ensured that criticality does not occur during normal use and under potential accident conditions. For example, the maximum fuel enrichment (ie, weight and percent weight of U235) that a fuel transport container can transport is approved by the Nuclear Regulatory Commission (NRC) for each fuel assembly design. In order for a new shipping container design to be licensed, it must demonstrate compliance with the NRC's requirements that the new shipping container design will meet the requirements of NRC rules and regulation...
