Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as figure 2 A nuclear fuel assembly flow detection device shown includes a control system 1, a water pump 2, a surge tank 3, an insulation tank 4, a heating system 5, a detection container 6, a standard flow meter A7, a standard flow meter B8, and a water source 9.
[0027] The water pump 2, the insulation tank 4, the standard flowmeter A7, the detection container 6, the standard flowmeter B8, the heating system 5 and the surge tank 3 are sequentially connected through pipelines to form a closed loop. The pipe diameter is 125mm.
[0028] The water source 9 communicates with the insulation tank 4, and the flow of the water source 9 flowing into the insulation tank 4 is controlled by a valve.
[0029] The nuclear fuel assembly to be tested is vertically placed in the testing container 6 .
[0030] The water pump 2, the h...

The invention relates to the technical field of flow detection, and particularly discloses a flow detection device for nuclear fuel assemblies. The flow detection device comprises a water pump, a heatpreservation tank, a standard flow meter A, a detection container, a standard flow meter B, a heating system and a pressure stabilization tank. The water pump, the heat preservation tank, the standard flow meter A, the detection container, the standard flow meter B, the heating system and the pressure stabilization tank are sequentially connected with one another by pipelines to form a closed loop in an enclosed manner. The flow detection device has the advantages that the uniform internal flow of the nuclear fuel assemblies and the uniform internal flow of pipelines can be guaranteed by theflow detection device in use procedures, tests carried out by the flow detection device can be guaranteed against being affected by external conditions, and accordingly the accuracy of detection results can be guaranteed.
Description
technical field [0001] The invention belongs to the technical field of flow detection, and in particular relates to a flow detection device for a nuclear fuel assembly. Background technique [0002] Fuel assembly flow detection is an internationally advanced technology, and there are few domestic researches on this type of product, so there is currently no method for reference at home and abroad. [0003] Such as figure 1 As shown, the fuel assembly is an object with relatively irregular geometry. When performing flow detection, the assembly needs to be placed vertically, clamped and sealed by a special fixture, and the high-temperature medium is pressed from one end of the assembly to the other end by the power system to form a stable flow. medium. At present, there are test methods such as standard table comparison method and mass method for detecting liquid flow rate, but due to the particularity of the fuel assembly structure, the existing detection technology cannot m...
