Abstract

Abstract

The Power Spectrum Density（PSD） of neutron noise induced by the Core barrel vibration of has been carried out.This work verifies that the vibration frequencies and amplitudes can be obtained by analyzing the neutron noise,and indicates that the validity of vibration monitoring to internals using neutron noise.critical installation is analyzed,and the analysis demonstrates the possibility of obtaining the vibration char-acteristic of core barrel from PSD of neutron noise.Calculation methods for the scale factor between PSD of neutron detectors and the vibration amplitude of core barrel are introduced and the corresponding calculation
- Core barrel,
- Vibration,
- Neutron noise,
- PSD,
- Scale factor
