Abstract
The use of Mechanical Shim to control core reactivity changes causes rod position-dependent changes in calibration relationships used to determine the values of Reactor Power and Axial Flux Difference (AFD) determined from Power Range detectors. To support the real-time plant control system, it is required to compensate this Power Range signal. This paper introduces a new method of Ex-core nuclear instrument signal compensated by continuous measured In-core nuclear instrument signal, and the compensated signal is used for Tavg and AFD control.
