Embodiment 1

[0031] Such as figure 1 , 2 , 3, during implementation, the irradiation tank 15, the lower cover plate 17, the upper cover plate 6, the air intake pipe 14, and the protective tube 5 are fully welded together by manual argon arc welding to form a relatively independent irradiation space. In the irradiation space, the lower pad 16 is installed at the lower end, the sample 12 is installed in the middle hole of the clamping block 11, the thermocouple is installed in the vertical groove opened on the contact surface between the clamping block 11 and the sample 12, and the electric heating wire is wound on In the annular groove on the outer surface of the clamping block 11, the installed clamping block 11, sample 12, thermocouple and electric heating wire are installed on the lower pad 16, and the displacement sensor 10 is installed on the support clamping block 8, and is fixed with a set screw 9 for fastening, the support ring 7 is a thin-walled round tube, installed between the u...

Embodiment 2

[0036] On the basis of Example 1, the displacement sensor 10 can be replaced, and a displacement sensor that can detect diameter changes can be selected to realize the detection of radial dimension changes of irradiated samples under different power levels and different temperatures of the HFETR stack. Or install a displacement sensor that can detect axial displacement changes and radial displacement changes at the same time, to realize the detection of axial and radial dimension changes of irradiated samples under different power levels and different temperatures of the HFETR stack.

Abstract

The invention discloses a deformation measurement irradiation device. The deformation measurement irradiation device comprises a measurement part on the lower portion, and the measurement part comprises an irradiation tank, a clamping block, a data collector and a temperature adjusting mechanism, wherein a sealed space is formed in the irradiation tank; the clamping block, the data collector and the temperature adjusting mechanism are arranged in the sealed space; the clamping block is arranged on the internal bottom of the irradiation tank, a hole for placing a sample is formed in the clamping block, the data collector is arranged above the hole, and a suitable gas gap is formed between the clamping block and the inner wall of the irradiation tank; the temperature adjusting mechanism comprises a first adjusting mechanism body and / or a second adjusting mechanism body, the first adjusting mechanism body achieves temperature adjustment by changing the thermal resistance of the gas gap, and the second adjusting mechanism body adjusts the test temperature of the sample by adjusting the voltage of a heating wire in an annular clamping block groove. By means of the device, under the environmental condition that the irradiation temperature is changed, more precise deformation measurement data can be obtained.

Description

technical field [0001] The invention relates to the field of radiation deformation measurement, in particular to a deformation measurement radiation device. Background technique [0002] In the process of research and development of materials for new reactors and localization of imported materials, in-reactor irradiation of related materials is one of the indispensable links. The traditional material irradiation process generally includes the following processes: preparation of standard samples, design of irradiation devices, assembly of samples and irradiation devices, irradiation of irradiation devices into piles, testing of mechanical properties after irradiation, data analysis and theoretical analysis. all. This irradiation process can only obtain the cumulative effect of the irradiated samples in the irradiated environment, but does not reveal the change process of the irradiated samples during the irradiation process. difficulty. Moreover, the mechanical property te...
