In configuration I-2A, an L-shaped hafnium control blade (half of a real cruciform blade) is inserted adjacent to the north-west corner of the central fuel assembly.
The new cars have a round of improvements such as updates to the "control blade" rear suspension system, a wider rear track and a quicker ratio for the steering, which now has electric power assistance.
It could be shown, that the design of the control blade plays a dominant role for the occurrence of local power peaks while instantaneously moving down the control rod.
An active control system is developed to control blade as well as rotor vibrations in a coupled rotor blade system where rotor lateral and blade flexible movements are coupled.
On bulldozers, high-technology electronics devices control blade operations, engine speed and emissions as they push dirt and gravel.
Burn-up and energy deposition were simulated with high spatial granularity, especially in the vicinity of the control blade tip.
It is found that the hydride fuel bundle design can be simplified by eliminating water rods and replacing the control blade with control rods.
It reduces the number of blades in the core during normal operation by 50% in comparison to a similar fuel cycle core design with regular inventory of control blades.
The objective is to design fuel bundles, and to use them for developing a core design, that minimizes (but does not eliminate) the use of control blades during operation.
The control blades are the primary control mechanism to address the need for performing reactivity adjustments (using fine-motion drives) at or near rated steady state power.
