Abstract

PURPOSE: To absorb the expansion and contraction of Na and efficiently remove included air by disposing a cylinder which is connected at the bottom end of an Na inlet nozzle and has the specific opening area in the upper part within an expansion tank provided with the Na outlet nozzles at the bottom.
CONSTITUTION: An inside cylinder 11 which connects to an Na inlet nozzle 12 at the bottom and is opened upward is provided to the inside of an expansion tank body 10 nearly similar to that in the prior art. Plural Na outlet nozzles 13 and an aggregating nozzle 14 are provided to the lower part of the tank so that all the Na passes the tank 10 inside. The top end opening area of said inside cylinder 11 is selected at a value smaller than 1/2 the sectional area of the tank 10. Hence, the ascending velocity of flow into the inside tower 11 becomes higher than the descending velocity of flow and the gas gathering in the upper part passes the free liquid surface and dissipates into the space. The expansion and contraction of Na are absorbed in this way, and since the included bubbles may be removed efficiently, the occurrence of cavitation may be eliminated.
