Abstract

PURPOSE: To improve the functions of immediate detection of fuel damage and detection positioning by means of a gas storage provided in the course of the sampling tube of a cooling sodium so as to collect and detect bubbles generated by fuel damage.
CONSTITUTION: In the course of a sampling tube, provided is a gas storage with a diameter larger than that of the tube 11. Bubbles 17 generated by fuel damage flows into the tube 11 due to a dynamic pressure of the cooling sodium, floating up and collected with the storage 15. During the sampling, the course from the inlet of the tube 11 to a solenoid pump turns vaccum. Therefore, bubbles collected into the gas storage expands and passes through a flow gauge 3. changing the reading. In this manner, the sensing and detection positioning are made possible
