Background technique

Fourth-generation nuclear reactors such as lead-cooled fast reactor (LFR), molten salt reactor (MSR), and sodium-cooled fast reactor (SFR) are research objects of widespread concern in the scientific and engineering circles. Among them, the performance testing of in-reactor materials such as fuel cladding and pressure vessels is a key issue that affects the successful development of the reactor. Different from other industrial application fields, the service conditions of the above-mentioned in-reactor materials are often multi-physics coupling environments, which usually need to withstand coupling effects such as high temperature, particle irradiation, and liquid corrosion. Therefore, conducting multi-physics coupling tests close to actual operating conditions is of great significance to the development of in-reactor materials.

As the research on materials in the reactor continues to deepen, the testing equipment for testing materials in the reactor is also constantly updated. One of the main updates of the test equipment is the upgrade from a single physical field test equipment to a multi-physics coupled test equipment. The multi-physics coupling test device can provide multiple coupled physical fields for the testing of materials in the reactor, making the test environment closer to the actual use conditions of the materials in the reactor. Although the traditional multi-physics coupling test device is more efficient than a single object Great advances have been made in test equipment for physics. However, traditional multi-physics coupled testing devices usually place the sample of the material to be tested in the vacuum environment of the accelerator. Once the isolation window is damaged, the corrosive liquid can easily rush into the vacuum environment of the accelerator.

The diameter of the sample to be tested is 3mm~10mm, and the thickness is 20μm~200μm.

For example, the SRIM 2011 commercial software is used to calculate the theoretical thickness of the 12Cr-F/M steel sample to be tested, and the sample to be tested is prepared based on the theoretical thickness29. Furthermore, using the SRIM 2011 commercial software, the theoretical thickness of the 12Cr-F/M steel sample to be tested was calculated to be approximately 50 μm. Accordingly, wire cutting, 500-3000# sandpaper polishing, and fully automatic vibration polishing methods were used to prepare a 10mm diameter disc sample with a flat and smooth surface, and its average thickness was measured by a scanning electron microscope (SEM) to be 50 μm. (Error ≤ 5%).

Transfer the corrosive liquid in the second corrosive liquid housing 4 to the first corrosive liquid housing 1 through the corrosive liquid inlet pipe 11;

The first corrosive liquid shell 1 is heated by the first heating element 2 to maintain the temperature of the corrosive liquid at 350°C; a helium purge area is formed between the through hole and the outlet of the beam pipe 25 by the helium purge element; The particle flow is generated by the accelerator host 24; the particle flow is led out through the beam pipe 25, and passes through the transmission film 26, the helium purge area and the through hole in sequence, and then the sample 29 to be measured is irradiated with particles.

In a specific example, when the first oxygen measuring component 21 detects that the oxygen content of the corrosive liquid 30 in the first corrosive liquid housing 1 is not in the range of 1±0.2×10 ^-7 wt%, the first corrosive liquid housing is The corrosive liquid 30 in the body 1 is recharged. The refueling method includes: transferring the corrosive liquid 30 in the first corrosive liquid housing 1 into the third corrosive liquid housing 7 through the corrosive liquid outlet pipe 13 . Optionally, the third corrosive liquid housing 7 can be insulated through the third insulation layer 8 to prevent the high-temperature liquid from rapidly cooling. When the corrosive liquid 30 in the first corrosive liquid housing 1 is transferred to the third corrosive liquid housing 7 , the corrosive liquid in the second corrosive liquid housing 4 is transferred to the first corrosive liquid through the corrosive liquid inlet pipe 11 In the housing 1, the first oxygen measuring component 21 is used to detect the oxygen content of the corrosive liquid 30 in the first corrosive liquid housing 1. When the oxygen content enters the range of 1±0.2×10 ^-7 wt%, it indicates that the refueling is completed. When the material change is completed, close the liquid inlet valve 12 and the liquid outlet valve 14.

After the test of the sample to be tested 29 is completed, the accelerator host 24 and the helium gas cylinder 27 are first closed. Subsequently, protective gas is filled into the second corrosive liquid housing 4 through the protective gas supply member 9 . Then the liquid inlet valve 12 and the liquid outlet valve 14 are opened, so that the corrosive liquid 30 in the first corrosive liquid housing 1 is transferred to the third corrosive liquid housing 7 , and the third corrosive liquid housing is detected through the liquid outlet liquid level detector 20 When the liquid level of the corrosive liquid 30 in the body 7 remains unchanged, it indicates that the corrosive liquid 30 in the first corrosive liquid housing 1 has been emptied. Next, the protective gas supply part 9, the inlet liquid level detector 17, the second temperature measuring part 18, the second oxygen measuring part 19, the first oxygen measuring part 21, the first temperature measuring part 22, and the first heating part are closed in sequence. Part 2, second heating part 5, liquid inlet valve 12 and liquid outlet valve 14. Finally, when the first corrosive liquid housing 1 When the temperature drops to room temperature, remove the sample on the first seal 23.
