DETECTING OF COOLANT BOILING IN VVER-1000 CORE ON THE BASE OF NEUTRON FLUX NOISE DUE TO FLUCTUATIONS OF COOLANT PARAMETERS
17th Symposium of AER on VVER Reactor Physics and Reactor Safety (2007, Yalta, Crimea (Ukraine, back then))
CORE SURVEILLANCE AND MONITORING. CFD ANALYSIS
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.
