Abstract
PURPOSE:To perform detection which is less in malfunction and is highly reliable over a long time by performing supervising with a radiation ionization detector at all time, and performing rechecking of leakage with a semiconductor type detector. CONSTITUTION:In the stage of ordinary operation, the 3rd valve 8 is opened, and the 1st, 2nd valves 2, 5 are closed to flow a sampling gas through an inflow pipe 1 then through a bypass pipe 9, the 3rd valve 8, a bypass valve 9 and a connection pipe 6. The leakage of sodium is detected with a radiation ionization detector 7. At the point of the time when the detector 7 responds and its output attains an output B by exceeding the set value A, the 3rd valve 8 is closed, the valves 2, 5 are opened, and the detector 7 and a semiconductor type detector 4 are operated simultaneously. When the leakage of sodium is checked with the detector 4 as well, the signal for the leakage of sodium is emitted, whereby the malfunction for suspended solids other than sodium is also checked.
