Abstract

The paper discusses investigation results of SPND signals for noises caused by fluctuations of coolant parameters. The dependence of neutron flux amplitude oscillations (local power) in SPD locations on the value and frequency of fluctuations of coolant parameters (pressure, flow rate, temperature) is analysed in the paper.
