Abstract

PURPOSE: To separate and remove impurities exactly by providing a path to a cold trap for liquid metal used for the coolant of nuclear reactor in such a way that the temperature distribution of impurities-arresting portion is lowered along the vertical flow direction.
CONSTITUTION: The metal Na coming into the cold trap body 10 from the inlet tube 24 is introduced through the top of the inside cylinder 11 to the outward radial direction and then flowed through the cooling path 12 to the trapping portion 18 where impurities such as sodium oxide, etc., in the metal Na deposit. On the other hand, the metallic Na goes up through the path 14 and during the period, is heated by the metallic Na passing through the cooling path 12. It passes through the packed layer 17 provided in the partition part 13 and goes down, during which separated inpurities are removed. Because the packed layer 17 is designed to gradually lower its temperature from upper part to lower part along the flow direction, impurities are separated at respective temperatures and arrested.
