LIQUID METAL REACTOR WITH DIRECT CONNECTION OF INTERMEDIATE HEAT EXCHANGE INLET/OUTLET TO UPPER PART OF HEAT GENERATOR

摘要

PURPOSE: A liquid metal nuclear reactor for connecting directly an entrance/exit of an intermediate heat exchanger with an upper portion of a vapor generator is provided to reduce the capacity of an electronic pump by simplifying a structure of an existing nuclear reactor. CONSTITUTION: An entrance/exit pipe arrangement(3,4) of a sodium cooling material is connected directly from an upper portion of a vapor generator(2) to an upper portion of an intermediate heat exchanger(1). A rising tube(9) for rising a cooling material is installed at a center of an inside of the vapor generator(2) connected with the pipe arrangement(4). A jet pump(11) and an electronic pump(10) are installed sequentially within the rising tube(9).
