Abstract—After numerous years of international research and development, there is a broad technical consensus that deep geological disposal is the method for the management of High-Level Radioactive Waste (HLRW). Deep geological disposal offers relatively enough space to accommodate the large volume of HLRW accumulated over the years will provide safety of to humankind and the environment for now and far into the future. This paper presents the methodology that the analytical solution of the general temperature field of the HLRW underground disposal repository can be approximately obtained by performing the calculations of Gaussian numerical integration and Gaussian quadrature. The process of the calculations has been compiled to the MATLAB codes by the authors. The verification of the results confirms that the method of this study is feasible and accurate.

Index Terms—The analytical solution of the general temperature field, deep geological disposal, Gaussian quadrature, the thermal conductivity of host rock.
