Analysis of the sodium-water steam generator protection usina the signals of magnetic flowmeters

The influence of background noises on the efficiency of a system for sodium-water steam generator leak detection based on the formation of difference signal from inlet and outlet magnetic flowmeters is investigated. It is shown that signal filtration gives an opportunity to decrease the probability of false operations and ensures reliable detection of leaks of about 1 g/s and more for sodium flow rate up to 100 m3/h
