Abstract: A computing system includes at least a first division and a second division. The first division has a first clock rate and the second division has a second clock rate. The computing system includes a first processor configured to execute a task on the first division and a second processor configured to execute the task of the second division. The task executed on the first division operates according to the first clock rate, and the task executed on the second division operates according to the second clock rate. A method of executing a task in order to reduce common mode failures in a computing system includes varying a program speed of each of the plurality of divisions such that the task, when executed on a corresponding one of the plurality of divisions, operates at a clock rate according to the corresponding one of the plurality of divisions.

Abstract: Methods and apparatus for moving fuel bundles in a reactor pressure vessel (RPV) of a nuclear reactor are described. In one embodiment of the apparatus, a support tube facilitates the positioning of a multiple channeled magazine within the RPV, especially at locations adjacent fuel bundles. In the one embodiment, the support tube extends in the reactor pressure vessel into the area above the top guide. A magazine assembly is coupled to the support tube, and includes a magazine having a plurality of fuel bundle receiving channels. The magazine extends from the support tube so that it is adjacent the fuel bundles and the top guide. Grapples extend through the magazine channels, engage the fuel bundles, and retract the bundles into the magazine channels. The magazine and support tube, and thus the bundles, are then moved.
