Effectiveness of Multiple Control Rods

Journal of Nuclear Science and Technology, 1966
A new approximate method for calculating the effectiveness of multiple control rods fully inserted in a reactor is described. This method is appicable to a bundle of many control rods, regardless of the number of rods, as well as to an array of a limited number of few rods.

Control Rod Calibration Experiment

AbstractTo assure the safety of a nuclear reactor during operation, it is important to know the control rod worth, which is an absolute value of negative reactivity induced by a control rod insertion. The measurement for the control rod worth is known as the control rod calibration.

Study on Reactor Power Control Strategies Based on Mode-C Operation and Control Mode

Energies
At present, the operation control modes of pressurized water reactor (PWR) nuclear power plants in service mainly include Mode-A, Mode-G, and MSHIM. Mode-A is mainly applicable to base load operation and cannot realize load tracking.

Topologically controlled synthesis of active colloidal bipeds

Nature Communications
Topological growth control allows to produce a narrow distribution of outgrown colloidal rods with defined and adjustable length. We use an external magnetic field to assemble paramagnetic colloidal spheres into colloidal rods of a chosen length.

The Structural Design, Kinematics, and Workspace Analysis of a Novel Rod–Cable Hybrid Cable-Driven Parallel Robot

Biomimetics
This study presents a novel rod–cable hybrid planar cable-driven parallel robot inspired by the biological synergy of bones and muscles. The design integrates rigid rods and flexible cables to enhance structural stability and precision in motion control.
