Experimental study on the physico-mechanical properties of Tamusu mudstone-A potential host rock for high-level radioactive waste in Inner Mongolia of China
文献摘要：
Tamusu mudstone,located in Bayin Gobi Basin in Inner Mongolia of China,has been selected as a po-tential host rock for high-level radioactive waste(HLW)disposal in China.A series of tests has been carried out,including X-ray diffraction(XRD)tests,scanning electron microscopy(SEM)tests,disinte-gration tests,permeability tests and triaxial compression tests,to estimate the physico-mechanical properties of Tamusu mudstone in this work.The mineral composition of Tamusu mudstone was analyzed and it was considered as a stable rock due to its low disintegration rate,i.e.approximately 0.11％after several wet/dry cycles.Based on the results of permeability test,it was found that Tamusu mudstone has a low permeability,with the magnitude of about 10-20 m2.The low permeability makes the mudstone well prevent nuclide migration and diffusion,and might be influenced by temperature.The triaxial tests show that Tamusu mudstone is a stiff mudstone with high compressive strength,which means that the excavation disturbed zone would be smaller compared to other types of mudstone due to construction and operation of HLW repositories.Finally,the properties of Tamusu mudstone were compared with those of Opalinus clay,Callovo-Oxfordian(COx)argillite,and Boom clay to further discuss the possibility of using Tamusu mudstone as a potential nuclear waste disposal medium.
