The redox behavior of uranium on Beishan granite: Effect of Fe2+ and Fe3+ content

Journal of Environmental Radioactivity, 2020
The Beishan granitic area in Gansu Province is a site with the greatest potential for a repository of high-level radioactive waste (HLW) in China. In this study, the redox behavior of uranium on Beishan granite was investigated at pH values from ~4.4 to ~9.2.

Determination of the effective diffusion coefficient for 125I− in Beishan granite

Radiochimica Acta, 2008
With the policy of active development of nuclear energy in China in the following 20 years or more, the high-level radioactive wastes and spent fuels will increase considerably. In order to dispose of these wastes safely, China plans to construct a geological repository in the middle of the 21st century.

Experimental characterisation of thermo-mechanical coupling properties of Beishan granite

European Journal of Environmental and Civil Engineering, 2015
With the help of MTS815 rock mechanics test system and 3D acoustic emission monitoring system, a series of thermo-mechanical coupling tests at temperatures in the range of 23–90 °C and confining pressures from 5 to 30 MPa are carried out, to investigate the thermo-mechanical properties of Beishan granite.

Evolution of thermal damage and permeability of Beishan granite

Applied Thermal Engineering, 2017
Abstract Thermal damage in Beishan granite subjected to high temperature treatment (from 100 °C to 800 °C at different heating rates, ranging from 1 to 15 °C/min) is studied in order to assess the thermal effect on physical and mechanical properties.

Experimental study on permeability of Beishan granite

2011
Rock engineers involved in the design and construction of nuclear waste repositories need to know the permeability of Beishan granite under high stress. A series of permeability tests were performed on specimens of Beishan granite at different axial stress levels and confining stresses.

Influence of Thermal Treatment on the Thermal Conductivity of Beishan Granite

Rock Mechanics and Rock Engineering, 2018
Granitic rocks are potential rock types for hosting high-level radioactive waste (HLW) repositories at depth. A better understanding of rock thermal conductivity is essential to develop HLW repositories successfully. In this work, experimental investigations on the thermal conductivity of thermally treated Beishan granite were conducted. Disk specimens
