Feasibility Study for Evaluation of Control Rod Worth in Pressurized Water Reactors using Neutron Count Rate during a Control Rod Drop Testing

Large-eddy simulation, fuel rod vibration and grid-to-rod fretting in pressurized water reactors

The grid-to-rod fretting (GTRF) problem in pressurized water reactors is a flow-induced vibration phenomenon that results in wear and failure of the cladding material on fuel rods. Grid-to-rod fretting is responsible for over 70% of the fuel leaks in pressurized water reactors in the U.S. The GTRFinduced wear process involves turbulent flow, mechanical vibration, tribology, and time-varying irr...

Experimental Hysteresis Identification and Micro-position Control of a Shape-Memory-Alloy Rod Actuator

In order to exhaustively exploit the high-level capabilities of shape memory alloys (SMAs), they must be applied in control systems applications. However, because of their hysteretic inherent, dilatory response, and nonlinear behavior, scientists are thwarted in their attempt to design controllers for actuators of such kind.  The current study aims at developing a micro-position control system ...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
