Embodiment 1

[0021] Such as Figure 1~2 As shown, the experimental device used for the study of the diffusion of actinides in the high-level radioactive waste repository, the diffusion device is composed of the stock solution pool 4 and the diffusion pool 1. The side of the stock solution bottle 4 is provided with a connector 5, the diffusion cell 1 is fixed on the connector 5 of the stock solution bottle 4 and communicates with the inside of the stock solution bottle 4, the diffusion cell 1 has a bottom cover 6, between the bottom cover 6 and the connector 5 Locked by locking mechanism 2. The locking mechanism 2 is a bolt, and the bolt locks the diffusion cell 1 between the connecting head 5 and the bottom cover 6 through the threaded hole 11 on the connecting head 5 and the bottom cover 6 .

[0022] Diffusion cell 1 is cylindrical, and its material is PTFE or stainless steel. The interior of the diffusion cell 1 is filled with a porous material 3 , and the porous material 3 is formed b...

The experiment device can be operated for a long time, and is suitable for migration experiments of uranium, neptunium and plutonium.

Description

technical field [0001] The invention belongs to the research field of geological disposal of high-level radioactive waste, and in particular relates to an experimental device used for the research on the diffusion of actinide elements in a high-level radioactive waste disposal storehouse. Background technique [0002] Establishing a geological repository for high-level radioactive waste is currently the best way to dispose of spent fuel from nuclear power plants. It adopts the design idea of ​​"multiple barrier system", which is mainly divided into "engineering barrier" and "natural barrier". Countries choose different lithology as natural barriers according to different geological conditions, usually choose granite, clay rock and tuff as natural barriers; choose bentonite as engineering barriers. In order to ensure the long-term safety of these isolation barrier buffer materials, it is necessary to carry out scientific experiments on these systems to simulate the retardati...
