ABSTRACT:
Disclosed is a sodium ionization detector (SID) for detecting sodium leaks by detecting the magnitude of fluctuation of the ion current produced by thermally ionizing sodium. There is a particular relationship between the magnitude of fluctuation of the ion current and the concentration of sodium. The sodium ionization detector is adapted to determine the magnitude of fluctuation of the ion current so as to compare it with a predetermined value. The magnitude of fluctuation of the ion current is determined, for example, by the root-mean-square value of a fluctuation component of the ion current.
