Abstract

PURPOSE:To detect the concentration of Na and Na compound in gas extending over a wide range in a short time, by introducing Na vapor into a receptacle put in water and reacting with the water and then, measuring the concentration of hydrogen ion of reacted liquid. CONSTITUTION:A receptacle 1 put in a water 2 is evacuated through an exhaust pipe 7 connected to a suction pump 6 and gas to be tested exsisting in a space wherein liquid Na flows, between a piping 4 and a heat insulating material 5 is introduced into the water 2 through an introducing pipe 3 to cause to react Na and the water 2. Further, the concentration of hydrogen ion of this reacted water 2 is measured by a glass electrode 8 and measured value is amplyfied by an indicator 10 through an electrode cable 9 and then, is converted into an electric signal and is introduced into a recorder 11 and an alarm 12. Moreover, the water 2 in the receptacle 1 is discharged from a valve 16 through a feeding and discharging water pipe 13, a valve 15 and a pump 14 provided to the bottom of the receptacle 1, thereafter, a valve 17 is opened and the water is fed by a pump 14. Hereby, leakage of the liquid Na used for cooling material of a high speed breeder is quickly detected with high accuracy.
