Experimental researching of buffer material specimen
Nuclear power is a highly efficient clean energy.With the widely applying of nuclear energy, nuclear waste disposal is increasingly paid attention.Bentonite is selected as the buffer material of high-level radioactive waste repository which is because that it has a very low water conductivity, great capability of thermal insulation, excellent expansion and good adsorption properties of radionuclides.While bentonite as a buffer material needs to be compacted and remodeling.Its special properties are not fully applicable to existing norms bentonite laboratory tests.In this paper, bentonite, the buffer material for nuclear waste disposal, is studied by axial compression tests.According to associated test codes and references, specimen preparation method is designed, and the related strength of buffer material specimens in laboratory experiments analyzed.
