NUCLEAR FUEL IRRADIATION TEST VESSEL HAVING PASSIVE MEMBER FOR CHANGING FLOW

摘要

PURPOSE: A nuclear fuel irradiating test container including a passive flow switching device is provided to improve stability by automatically changing a flow path in a remaining heat removing direction according to the operation of a pump. CONSTITUTION: A pressure case(20) has an outlet nozzle which discharge coolants on the upper side thereof. An inlet nozzle(24) is formed on the lower side of the outlet nozzle to input the coolants. A flow separation tube(40) is separated from the inner side of the pressure case. A flow hole(42) is formed on one side of the flow separating tube. A nuclear fuel(1) is arranged in the flow separation pipe.
