Quick boron applying device for boron-coated tank of boron-coated neutron detector and working method thereof

Abstract

The invention relates to the field of nuclear radiation detection, and provides a quick boron applying device for a boron-coated tank of a boron-coated neutron detector and a working method thereof. The device comprises a stepper motor, a coupling screw, an end compression plate, a positive electrode core body, an output screw, and a graphite brush. The graphite brush closely abuts on the outer wall of a boron-coated tank, conducts electricity through linear contact, and is loaded with a negative electrode. A base, a bearing, the output screw and the positive electrode core body are metal conductors, conduct electricity through series connection, and are loaded with a positive electrode. Under the action of the voltages of the loaded positive and negative electrodes, boron complexes in boron-coated solution are precipitated out from the positive electrode to the negative electrode to form a boron film with uniform thickness. The device is simple in structure, convenient to operate and reliable in sealing, can be used repeatedly, and is of lower manufacture cost and higher universality. The boron applying device can freely and accurately control the thickness of boron applied, and is of good consistency. Moreover, through organic mechanical and electrical integration and automatic programmed control, the production efficiency of the boron-coated neutron detector is improved.

Description

technical field [0001] The invention relates to the field of nuclear radiation detection, in particular to a fast boron-coating device for a boron-coated liner of a boron-coated neutron detector and a working method thereof. Background technique [0002] In the field of nuclear radiation detection, boron-coated neutron detectors are key components used in the core area of ​​the plant, and are used in large quantities and widely used. In the manufacturing process of boron-coated neutron detectors, the technical bottleneck lies in the production of the detection sensitive body, that is, the boron-coated liner. The traditional boron-coated technology has the disadvantages of uncontrollable boron-coated coating thickness, poor adhesion, and uniform circumferential and axial directions. There are a series of problems such as cumbersome disassembly, assembly and sealing, and high scrap rate. Therefore, improving the quality and efficiency of boron coating is of great significance...
