摘要： An improved gas circulator for a gas-cooled nuclear reactor system is disclosed which includes a stator, a rotor having a rotor shaft, and an impeller attached to one end thereof. A radial active magnetic bearing and a radial backup bearing are positioned proximate each end of the rotor shaft. An axial active magnetic bearing is also located between the ends of the rotor shaft, as is an axial backup bearing, with two of the backup bearings enclosed within a sealed chamber that may contain a lubricant, for example, a solid lubricant or a liquid lubricant. Preferably, the gas circulator is installed in a nuclear reactor system with the rotor shaft in a substantially vertical orientation and the sealed chamber near the bottom of the rotor shaft. The lower radical backup bearing and the axial backup bearing are advantageously located within the sealed chamber. The lower radial backup bearing and the axial backup bearing may be spaced apart sufficiently to permit the lower radial backup bearing to provide substantially all radial support for the rotor when the radial active magnetic bearings are deenergized.

摘要： An apparatus for consolidating spent fuel rods from spent fuel assemblies includes a container with a bottom and front, back, and side walls. The container has a plurality of flutes positioned adjacent to the front wall, and the plurality of flutes defines a plurality of channels. The apparatus also includes a plurality of springs, which are mounted on a support. The springs bear against the flutes and the channels when no fuel rods have been inserted into the container and the support is located proximate the front wall. The springs assist in guiding a fuel rod into a preselected location in the container; the springs are capable of maintaining the fuel rod in the preselected location. Preferably, each spring is a resilient finger that extends outwardly from the support toward the front wall. The support may be a movable sheet. The apparatus advantageously includes a device for moving the support. Such a device may automatically position the support in response to control signals.
