[0019] The component proposed by the present invention adds a layer of water rod wall, so that the moderator flows in the opposite direction in the water rod, and then enters the double-layer water rod structure of the coolant channel. The following is an explanation with reference to the drawings.
[0020] image 3 It is a diagram of the flow mode of the working fluid in the core with a double-layer water rod assembly, which illustrates the flow mode of the working fluid in the core after adding a layer of water rod wall. image 3 The two ends of the passage 2 between the hanging basket 4 and the component outer wall 12 (pressure vessel) are connected to the upper chamber 1 and the lower chamber 9 respectively. The working fluid inlet 3 is connected to the upper part of the passage 2 between the hanging basket 4 and the component outer wall 12. The lower end of the inner pipe wall 13 of the water rod communicates with the lower chamber 9, the upper end of the outer pipe wall 13 o...
