Embodiment 1

[0017] like figure 1 As shown, a special sample hanger for nuclear fuel and material out-of-pile corrosion tests includes a hook 1, a cylinder 2 and a disc 3, wherein the hook 1, the cylinder 2 and the disc 3 are all made of corrosion-resistant materials. The hook 1 is connected to the central part of the upper end surface of the disc 3, the upper end of the cylinder 2 is open and the lower end is sealed, the number of the cylinders 2 is multiple, and the upper ends of the side walls of the plurality of cylinders 2 are all connected to the lower end surface of the disc 3, A plurality of cylinders 2 are evenly distributed under the disc 3 . The disk 3 is provided with sample through-holes that run through the upper and lower end surfaces of the disk 3, wherein the number of sample through-holes is the same as that of the cylinder 2, and the positions of the multiple sample through-holes and the opening ends of the multiple cylinders 2 are one by one. correspond.

Embodiment 2

[0020] The main difference between this embodiment and Embodiment 1 is that the sample through-hole in this embodiment is a circular through-hole whose diameter matches the inner diameter of the cylinder 2. influences.

Embodiment 3

[0022] The main difference between this embodiment and embodiment 1 or embodiment 2 is that: the disk 3 of this embodiment is formed with a plurality of first medium circulation holes penetrating through the upper and lower end surfaces of the disk 3, and the side wall and bottom of the cylinder 2 are provided with multiple A second medium flow hole connecting the inside of the cylinder 2 with the outside. When this embodiment is applied, the exchange flow of the corrosive medium can be ensured through the first medium flow hole and the second medium flow hole, thereby ensuring a uniform corrosive environment around all the samples.

Abstract

The invention discloses a special sample hanger for a nuclear fuel and material pile outer corrosion test. The special sample hanger comprises a hook (1), a circular disc (3) and a plurality of cylinders (2) with sealed lower ends, wherein the hook (1) is connected with the central parts of the upper end faces of the cylinders (2); the upper ends of the side walls of the plurality of cylinders (2) are all connected with the lower end face of the circular disc (3); the circular disc (3) is provided with sample through holes which are equal to the cylinders (2) in quantity and penetrate through the upper and lower end faces of the circular disc (3); a plurality of the sample through holes correspond to the positions of the opening ends of the plurality of cylinders (2) one by one. With the adoption of the structure, the special sample hanger is simple in whole structure and convenient to realize; when the special sample hanger is applied, samples with different shapes can be conveniently placed, so that the samples are convenient to operate when the nuclear fuel and material pile outer corrosion test is carried out, and the time and the labor are saved.

Description

technical field [0001] The invention relates to an auxiliary tool for nuclear fuel and material out-of-pile corrosion performance tests, in particular to a special sample hanger for nuclear fuel and material out-of-pile corrosion tests. Background technique [0002] In order to ensure the safe operation of nuclear power reactors, long-term corrosion tests simulating the working conditions in the reactor must be carried out outside the reactor before new fuels and materials are put into the reactor to test their corrosion resistance. Among them, the corrosion performance test must be carried out in a custom-made high-temperature autoclave dedicated to nuclear equipment. Due to the different types, specifications and shapes of fuel and materials, such as fuel rod type, spherical type and plate type, etc., and the materials are also tubular, plate-shaped and rod-shaped, etc., the current corrosion tests on nuclear fuel and materials are aimed at different shapes. The process o...
