The device has the advantages of convenient operation, can simulate local environment conditions of the high-level radioactive waste geological disposal repository, and ensures the high-efficiency assembly and smooth operation of a buffer material multi-field coupling test bed.
Description
technical field [0001] The invention belongs to the technical field of buffer / backfill materials for geological disposal of high-level radioactive waste, and in particular relates to a multi-field coupling test bench device for buffer materials. Background technique [0002] High-level radioactive waste is a special waste containing strong radioactivity, long half-life of nuclides, high toxicity, and high calorific value. It needs long-term and reliable isolation from the human living environment. The safe disposal of high-level radioactive waste is a major issue related to the national land environment, public safety, and the health and sustainable development of the nuclear industry. solve. In the prior art, the geological disposal of high-level radioactive waste can be carried out in the form of multiple barrier systems. As an important part of the multiple barrier system of the repository, the buffer material is the last artificial barrier filled between the waste tank ...
