Abstract: A method for performing diagnostics of coolant boiling in a VVER-1000 core is described. This method was developed at the Russian Science Center Kurchatov Institute and is based on monitoring the increase of the sensitivity of neutron flux noise to the fluctuations of the coolant parameters. This procedure is intended to be used as part of the in-reactor noise diagnostics system. It is now in commercial operation of the No. 3 unit of the Kalinin and two units of the Tianwan (China) nuclear power plants.
